Executive Summary This is the Second Five-Year Review of the Valley Wood Preserving Inc. Superfund Site. The purpose

of this Five-Year Review is to review information to determine if the remedy is and will continue to be

protective of human health and the environment. The triggering action for this Five-Year Review (FYR) was the signing ofthe previous FYR Report in September 2009.

In September 1991 , EPA issued a Record ofDecision (ROD) for the VWP Site. The remedy for groundwater was to utilize the existing extraction and treatment system and electrochemically treat the groundwater to change the hexavalent chromium to trivalent chromium followed by treatment using

activated alumina adsorption to remove arsenic. The soil remedy involved excavating contaminated soil and fixing and stabilizing the hazardous substances in the soil with a stabilizing agent. The soil would then be backfilled and capped. The chemicals ofconcern are arsenic and chromjum.

In September 2003, EPA issued a ROD amendment revising the arsenic cleanup standard for soil,

modifying the soil remedy, and selecting new institutional controls. Data on the background

concentrations ofnaturally-occurring arsenic in the Central Valley, not available at the time the original

ROD was released, demonstrated that the original arsenic cleanup standard for soil was below background levels. The change in cleanup standard for arsenic was coupled with the requirement for an institutional control (e.g., land use covenant) and rezoning prohibiting future residential development of

the VWP property. The modified soil remedy was to excavate the impacted soil (soils above cleanup standards) to the newly-promulgated standard for arsenic (25 mg/kg) and dispose the contaminated soil

offsite with concentrations above 25 mg/kg for arsenic or 4 mg/kg chromium IV. Following implementation of the soil excavation work in 2004, confirmation sampling determined that all soi ls in

the unsaturated zone with chromium and arsenic levels above their respective cleanup standards had

been removed.

In March 2007, EPA issued a second ROD amendment revising the cleanup standard for arsenic in the groundwater from 50 micrograms per liter (µg/L) to JO µg!L (consistent with the revised federa l Maximum Contaminant Level (MCL) for drinking water) and revising the remedy to address the

residual levels ofcontamjnants in the groundwater. This ROD Amendment selected the use of additional in-situ treatment followed by monitored natural attenuation (MNA) to address the residual

arsenic concentrations in the groundwater that remained onsite above the revised cleanup standard. The in-situ treatment consisted of injection ofViroBind™ F Blend reagent slurry into grid injection points

sunrounding the impacted area on the VWP property. The objective of the injections was to permanently immobilize and incorporate arsenic into ferrous iron minerals and to reduce the residual hexavalent

chromium to trivalent chromium.

The in-situ components to the groundwater remedy for hexavalent chromjum and arsenic were successfu l at reducing the areal footprint of the contamination plume to four wells remaining onsite.

Institutional controls implemented pursuant to the 2003 ROD amendment ensure that future use of the Site will be restricted to commercial and industrial purposes (certain specific uses are excluded by the

recorded land use covenant). The addjtional in-situ groundwater treatment also successfully reduced the

areal footprint of the arsenic contamination plume. Under the MNA component of the groundwater

Valley Wood Preserving Superfund Site Second Five-Year Review Report

remedy selected in the 2007 ROD amendment, VWP has continued to monitor wells to ensure the

groundwater reaches COC concentrations statistically below the MCL in a reasonable timeframe.

The remedy is functioning as intended. Past remedial actions have reduced contaminant concentrations

to levels below ROD cleanup I.evels for the majority of the wells. However, further assessment may be needed to determine the reason for the elevated concentrations at several wells. The exposure

ass111rnptions, toxici ty data, cleanup levels, and RAOs have not changed in the past five years. The State ofCalifornia has recently adopted an MCL for hexavalent chromium. No additional ecological risks

have been identified. No impacts from natural disasters have affected the protectiveness or activities of the Site. No additional information has come to light which would affect the protectiveness of the

remedy.

The remedy at Valley Wood Preserving Superfund Site currently protects human health and the

environment because land use controls have been implemented and enforced to ensure exposure to contaminant concentrations above the MCL is eliminated as well as prohibiting residential use at the Site, which has been remediated only to soil cleanup levels. However, in order for the remedy to be

protective in the Jong term, an evaluation should be conducted to assess the reason for the elevated

concentrations at several wells and to determine if the current remedy can achieve the new hexavalent chromium standard. Also, an Explanation of Significant Differences should be issued to select the new

State MCL as a groundwater cleanup standard for the Site.

Second Five-Year Review Report

for

Valley Wood Preserving Inc. Superfund Site

1. Introduction The purpose ofa Five-Year Review (FYR) is to evaluate the implementation and performance ofa

remedy in order to determine if the remedy wtill continue to be protective of human health and the environment. The methods, findings, and conclusions ofFYRs are documented in five-year review

reports. In addition, FYR reports identify issues found during the review, ifany, and document recommendations to address them.

The U.S. Environmental Protection Agency (EPA) prepares FYRs pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Section 121 and the National

Contingency Plan (NCP). CERCLA 121 states:

"If the President selects a remedial action that results in any hazardous substances, pollutants, or contaminants remaining at the site, the President shall review such remedial action no less often than each five years after tfre initiation of such remedial action to

assure that human health and the environment are being protected by the remedial action being implemented. In addition, ifupon such review it is the judgment ofthe President that

action is appropriate at such site in accordance with section {104} or {106}, the President shall take or require such action. The President shall report to the Congress a fist of facilities for which such review is required, the results ofall such reviews, and any actions

taken as a result ofsuch reviews."

EPA interpreted this requirement further in the NCP; 40 Code ofFederal Regulations (CFR) Section 300.430(f)(4)(ii), which states:

"If a remedial action is selected that results in hazardous substances, pollutants, or contaminants remaining at the site above levels that allow for unlimited use and

unrestricted exposure, the lead agency shall review such actions no less oft.en than every five years after the inWation ofthe selected remedial action."

EPA Region 9 has conducted the FYR and prepared this report regarding the remedy implemented at the Valley Wood Preserving, Inc. Superfund S ite, Stanislaus County, California. EPA is the lead agency for developing and implementing the remedy fo r the Site. DTSC and CVRWQCB are support

agencies, with DISC acting as the lead state agency.

This is the Second FYR for the Valley Wood Preserving Inc. Superfund Site (the VWP Site or the

Site) . The triggering action for this statutory review is the previous FYR in September 2009. The

Valley Wood Preserving Superfund Site Second Five-Year Review Report

FYR is required due to the fact that hazardous. s6ubstances, pollutants, or contaminants remain at the

Site above levels that allow for unlimited use and unrestricted exposure.

Valley Wood Preserving Superfund Site Second Five-Year Review Report 2

3. Background

3.1. Physical Characteristics

The VWP Site is located at 2237 South Golden State Boulevard in an unincorporated area of Stanislaus County, California. The Site, a fonner wood preserving facility, lies roughly ll .5 miles

southeast of the City ofTurlock's boundary (Figure 1). The Merced County line is about 0.5 miles

southeast of the Site.

The primary land use in the Site vicinity is agricultural; therefore, the area around the Site is lightly

populated. The immediate boundaries of the Site are South Golden State Boulevard to the east; a poultry fann to the south; agricultural lots to the west; and (currently) an automotive repair shop to the

north (Figure 2). The agricultural parcels near the Site are about 10 to 20 acres each.

The Site occupies an area ofapproximately 14.4 acres, and is primarily level. Parts of the Site have

been graded to control surface water runoff. The former wood treating and storage areas have been paved over. The remainder of the Site is unpaved. The entire perimeter of the Site is secured with a 6

foot (ft) high chain-link fence.

Within the Site boundaries, a garage/workshop and a storage shed are located in the northeast corner of the property. Two service/storage type buildings and a covered work structure are located in the southeast corner of the property. Jn addition, the property still contains one small above-ground tank

that stores surface water retrieved from pumps onsite, a pole lbam, and an office structure. The wood preserving facilities and equipment have been dismantled and removed.

3.2. Hydrology

This section provides an overview of the hydrogeology of the region and Site detailing the soil

makeup, depths and thicknesses of the aquifers in the region and onsite, and the general

geomorphology of the area.

3.2.1. Regional Geology The Site is located in the lowlands ofCalifornia's Great Valley that is approximately 400 mjles long, situated between the Sierra Nevada Mountains to the east and! the Coast Range Mountains to the west.

The Site is located in the San Joaquin Valley, the southern region of the Great Valley. The valley is a structural trough composed of over 9,000 feet of unconsolidated and consolidated marine and

continental sediments overlying a pre-Tertiary metamorphic and igneous basement complex.1 The valley geologic formations were deposited and fonned in periodic inundations by the Pacific Ocean

and by erosion of tlhe surrounding mountains, respectively. Continental deposits originating from the surrounding mountains form an alluvial wedge that thickens from the valley margins toward the axis

of the structural trough.

3.2.2. Local Hydrogeology The Site is located within the Turlock groundwater basin. The Turlock groundwater basin is a

subbasin of the San Joaquin Valley Groundwater Basin and Ines in the eastern portions ofStanislaus and Merced counties. The primary hydrogeologic units in the Turlock Subbasin include both

consolidated and unconsolidated sedimentary deposits that are as much as 16,000 feet thick within the western portion of the Subbasin. The unconsolidated deposits ofTurlock Lake, Riverbank, and

Modesto formations overlie the consolidated deposits. These deposits generally yield moderate to large quantities ofwater to wells and are the main water-yielding units of the subbasin. Fine-grained

deposits within the formations do not transmit substantial quantities of water and function as aquitards. The unconfined aquifer is generally 150 feet thick and is the water-table aquifer. This unconfined aquifer supplies the area for both private domestic supply and agricultural supply in the western part of

the subbasin. Wells less than 200 feet in depth draw from this aquifer. The confined aqumfer, which is contained under pressure by the Corcoran Clay, occurs in the deeper hydrogeologic units of the

sub basin.

3.2.3. Site Hydrogeology The bydrogeologic system on the Site can be divided into three major units. The upper-most aquifer

consists of unconsolidated gravel, sand, silt, and clay that ex.tends from the land surface to approximately 60 to 80 feet below ground surface (bgs). Ferric hydroxide is abundant and coats the grains of the aquifer.2 A pump test determined the hydraulic conductivity is 4.9 x I 0·2 centimeters per

second (cm/sec). This aquifer is classified by t he state as a drinking water source.

The upper zone uniformly overlies a continuous aquitard that has water with natural reducing

conditions, composed of lacustrine silt and clay that is about 40 to 90 feet thick. The reduced state produces an elevated level of arsenic and is an important consideration with respect to migration of

1 Geosystems. 1991. 2 MWH. 2006.

Valley Wood Preserving Superfund Site Second Five-Year Review Report 7

contamination onsite. Ferrous iron minerals are common. This unit produces low volumes ofwater;

the Remedial Investigation/Feasibility Study (RI/FS) reports hydraulic conductivity ranging from 1.4 x 10-6 to I.Ix 10-7 cm /sec.2

The aquitard is underlain by the second main aquifer system. This second aquifer is located 125 to 200

feet bgs. The aquifer is confined, and contains oxidized water.2 It consists of Pleistocene and

Holocene alluvium, gravel, sand, silt, and clay. As in the upper zone, ferric hydroxides are present This unit is capable ofyielding large volumes ofgroundwater1 and is also classified by the state as a

drinking water source. The groundwater flows to the southwest as determined from groundwater monitoring and historical data.

The Site is located completely in the Turlock Irrigation District (TID) and the Turlock Groundwater Basin. The TID utilizes a combination ofsurface and groundwater resources to service agricultural

lands and municipalities within the district boundaries.3 The upper zone of the groundwater basin was historically used as a source ofwater supply, but such use of this zone has been discontinued in favor ofdeeper zones. This is due to widespread nitrate contamination caused by the historical agricultural

use of the region. The use oforgano-arsenic herbicide is also common in the region.

3.3. Land and Resource Use

No one is currently using the Site. The area surrounding the Site consists ofagricultural lands that

include vineyards, vegetable farms, walnut orchards, poultry farms, and grazing lands. GIS data show

the area across S. Golden State Boulevard is industrial zoning and further to the south is planned development (Figure 4). During the onsite interview Bob Schmidt, the owner and representative of VWP, said the Site may be turned into a semi-truck parking lot and storing facility_The projected land

use of the surrounding area is presumed to be agriculture.

Figure 4. Land zoning around the VWP Site. Zoning data from Stanislaus County GIS (Stanislaus County 2006).

Organo-arsenic herbicide is commonly used in the surrounding area. In addition, studies have

indicated there is a naturally-occurring background concentration of arsenic in the soil and

groundwater. Of more than 2,000 domestic, irrigation, observation, a nd public supply wells in

Merced, San Joaquin, and Stanislaus Counties that were compiled in the databases of the U.S.

Geological Survey (USGS) and California Departme nt of Health Services (now the California

Department ofToxic Substances Control [DTSC]), 13 percent of the wells had groundwater

concentrations of arsenic greater than the maximum contaminant level (MCL).

3.4. History of Contamination

Valley Wood Preserving, Inc. occupied the Site and conducted wood preserving activities between

1973 and 1979. The process of preserving the wood onsite included placement ofup to 20,000 pounds

of lumber into pressure treatment cylinders which were treated with a 1 to 2 % chromate-copper­

arsenate (CCA) solution. After processing, the lumber was removed from the cylinder to drip-dry on

paved and unpaved portions of the property. The Central Va!Uey Regional Water Quality Control

Board (CYRWQCB) identified the presence ofwood preserving chemicals in the soil and groundwater

in L979. When identified in 19'79, the hexavalent chromium plume identified in the upper aquifer had

migrated over 2,500 feet southwest from the source. An arsenic plume was also identified in the upper

aquifer but it had not migrated far from the Site.

Valley Wood Preserving Superfund Site Second Five-Year Review Report 9

There were a number of sources the contamination has been attributed to; these include: unpaved drip

pads, chemical spills, leaking tanks, and onsite disposal practices common during that time.

Contamination was spread by the use ofstorage ponds, holding tanks, surface run-off, and soils both

onsite and offsite. The exact amounts (in mass) ofarsenic and hexavalent chromium that were leaked or migrated due to the disposal practices of the past is unknown. The highest groundwater concentration of total chromium detected was above 28,000 parts per billion (ppb) prior to remedial

actions. This concentration was seen at the following monitoring wells: GW-5, GW-15B, and GW-26.

The greatest concentration ofarsenic detected in the groundwater was 2,350 ppb prior to remedial actions.

3.5. Initial Response

In November 1979, the CVR WQCB issued a cleanup and abatement order to VWP. In 1980, the

CVRWQCB obtained a preliminary injunction ordering VWP to perform groundwater extraction and

treatment (pump-and-treat) actions at the Site. VWP commenced soil and groundwater sampling in early 1980; however, remedial actions ceased in 1983 due to alleged financial difficulties.

In March 1987, the DTSC issued a remedial action order to VWP. This order required VWP to conduct a remedial investigation/feasibility study (RVFS) and to develop a remedial action plan

(RAP).

In 1991 a total of 105 wells located within the study area were identified. Of the 105 wells, 91 were for domestic water use. Of those 91 wells, 10 were inactive. The 81 active domestic wells were tested

for levels ofhexavalent chromium in 1989. Some of the weUs contained concentrations ofhexavalent chromium elevated above background but at levels below California MCL for chromium. A consent

order, mentioned in the 1991 ROD, called for VWP to design a plan for the development ofan

alternative water supply for affected residents in the area. This alternative supply plan was to be put in effect if contamination levels reached 60 percent of the MCL. The plan included use of the three deep

groundwater wells VWP installed in 1990 to serve as domestic water supply, which at the time were determined to be "clean." ln 1991 three additional wells offsite along GolfRoad were replaced with

deeper water supply wells as a precaution against future contamination.

3.6. Basis for Taking Action

The primary contaminants ofconcern for the VWP Site were hexavalent chromium and arsenic. The presence of these contaminant(s) in soil and groundwater provided the basis for taking action under

the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). Hexavalent chromium and arsenic are considered possible human carcinogens. The primary threats to human health were posed by inhalation ofsoi ti dust from the Site, ingestion of soil, and ingestion of

groundwater.

The RVFS found contaminated soil and groundwater at the Site at levels exceeding health-based

limits. Groundwater contamination was present in the upper zone and elevated arsenic levels were

present in the underlying aquitard. EPA determined that, over time, the primary pathway for release

Valley Wood Preserving Superfund Site Second Five-Year Review Report 10

from the contaminated soil to the groundwater is via leaching, followed by plume migration due to

groundwater movement. Since hexavalent chromium is mobile in groundwater, a significant

contaminant plume was present in the upper zone and had migrated from the western Site boundary down-gradient in a southwesterly direction (Figure 5).

Similarly, an arsenic contamination plume in groundwater was also delineated around the western

boundary, though no significant migration onsite of this plume had occurred (Figure 5). Arsenic is not as mobile in groundwater as hexavalent chromium, and as a result the arsenic plume remained close to

the western property boundary (i.e., in the vicinity of the wood treating operations). Impacts to the soil were also centered on this western boundary of the Site for both hexavalent chromium and arsenic.

EPA prepared a baseline risk assessment to evaluate the potential risks associated with the contaminants found at the Site_ Routes ofexposure for both groundwater and soil evaluated in the risk

assessment included ingestion. inhalation, and dermal contact. EPA concluded that actual or threatened releases ofhazardous substances from this Site could present an imminent and substantial endangerment to human health. Arsenic and hexavalent chromium were identified as the contaminants

that posed the most significant risks under current and future exposure scenarios. The primary

potential exposure pathway of concern for groundwater at the Site was ingestion and for soil the primary potential route ofconcern was dust inhalation. No sigillficant ecological risks were detected.

4. Remedial Actions

4. 1. Remedy Selection

The remedy selection for YWP entailed remediation for both groundwater and soils, to reduce the risks ofcancer and negative impacts from chronic arsenic and chromium exposure. Following is the

description of the remedies, the reasons they were applied, and the list of documents that supports the

choice of remedy.

4 .1.1. 1991 ROD On September 27, 1991, EPA signed a ROD for the VWP Site that selected cleanup remedies for contaminated soil and groundwater. The remedy for the groundwater contamination consisted of electrochemical treatment, in conjunction with the existing extraction and treatment system. For

groundwater, the ROD selected cleanup standards of 50 µg/L for total chromium (which includes hex.avalent chromium) and 16 ~tg/L for arsenic (equal to 50 parts per billion (ppb) and l6ppb).

To address onsite contaminated soil, the ROD selected a remedy that included excavating

contaminated soil, fix ing and stabilizing the hazardous substances in the soil with a stabilizing agent, and backfilling the fixed-soils into the excavated areas. Measures such as capping by placing covers of

clean soil or other capping mechanisms would be taken to protect the surface of the fixed soil from

physical decomposition. Institutional controls would be required to ensure that future land-use practices would be compatible with the fixed-so il. Based on information available at the time of the

1991 ROD, it was estimated that 15,000 cubic yards ofsoi l would be subject to remediation.

The ROD specified cleanup standards for soil based on applicable or relevant and appropriate

requirements (ARARs) and health protection criteria. The surface soil cleanup standards were based on potential health risks from inhalation and direct contact, assuming residential use of the Site. The

standards for shallow soil (0 to 4 feet bgs) were set at 4 milligrams per kilogram (mg/kg) for hex.avalent chromium and 2 mg/kg for arsenic, which corresponded to a l x 1 o~ excess cancer risk.

The cleanup standards for subsurface soil , deeper than 4 feet bgs, were set at 5 milligrams per kilogram (mg/kg) for both arsenic and hexavalent chromium as measured in the leachate from the

subsurface soil. Those levels were based on the Soluble Threshold Limit Concentrations (STLC) as defined in the Designated Level Methodology (DLM) for characterizing wastes in soil prepared by the CVRWQCB in June 1989.

4.1.2. 1994 ESD In 1994 an Explanation ofSignificant Difference (ESD) declaration was completed. The ESD revised

the ROD with respect to the following groundwater cleanup changes:

• Cleanup levels and performance for groundwater remediation through the utilization of above­

ground electrochemical treatment, and in-situ treatment with the use of ionic reductants.

• The ESD also identifies all ARA Rs for the reinjection of groundwater after treatment.

The ESD selected a cleanup level for total chromium at 50 µg/L and a cleanup level for arsenic of 16

µg/L. The ESD made no changes to the soil remedy selected in the ROD.

4 .1.3. 2003 ROD Amendment On September 29, 2003, EPA issued the first of two ROD amendments revising the arsenic cleanup

standard for soil. The ROD amendment determined that the soil cleanup standards in the original ROD were too conservative because they were based upon the future residential use of the VWP property

and technical data not available at the time of the original ROD suggesting that the original cleanup standard for surface soil was below background concentrations. By 2003, VWP had submitted an application to have the VWP property re-zoned as "planned industrial" which would both effectively

prevent the construction of residences on the property and require local zoning input on the future industrial usage. In the first ROD Amendment, EPA revised the soil cleanup standards to reflect this change in future use of the VWP property and also required institutional controls (ICs) prohibiting

residential use of the Site to ensure that future use is compatible with post-cleanup Site conditions. The revised soil cleanup standards established in the first ROD amendment are summarized in (Table 2).

Table 2. Valley Wood Preserving Soil Clean-up Standards from 2003 ROD Amendment

*mg/kg - milligrams per kilogram = pa11s per million (ppm)

The amendment also modified the soil cleanup remedy. The remedy selected in the original ROD,

excavation, fixation, and backfilling offixated soil, was replaced by the new remedy that required that soil with concentrations ofarsenic and chromium exceeding industrial cleanup standards be excavated

and disposed offsite . The new p lan also eliminated the separate cleanup requirement for soluble

leachate soil in requiring that all soil meet a single standard. Because the remedy outlined in this ROD amendment would result in hazardous substances remaining onsite at levels above health-based levels, the Site became subject to the five-year review requirements.

Remedial action objectives (RAOs) describe what the site cleanup is expected to accomplish. ln the 2003 ROD amendment, the RAOs for the soil cleanup remedy at the Site remained the same as in the original ROD (EPA, 2003). They are as follows:

• Protect human health and the environment

• Protect groundwater quality based on the potential for arsenic and/or hexavalent chromium in the soils to contaminate the groundwater.

4 .1.4. 2007 ROD Amendment On March 30, 2007, EPA issued a second ROD amendment to address residual levels ofgroundwater contaminants and revise the cleanup standards. The groundwater remedy outlined in the second ROD

amendment called for: a) in-situ treatment to address residual levels ofarsenic contamination in groundwater beneath and

down-gradient from the Site,

Valley Wood Preserving Superfund Site Second Five-Year Review Report 14

b) monitored natural attenuation to address residual hexavalent chromium, any remaining levels of

arsenic following the in-situ treatment, and secondary contaminants generated by the in-situ

treatment, and

c) a revised cleanup goal of 10 micrograms per liter (µg/L) for arsenic in groundwater impacted by Site activities.4

The RAO for the Site groundwater remedy, as described in the second ROD amendment, is as follows:

• Restore groundwater to its beneficial use within a reasonable time frame.

The groundwater standards selected in the 2007 amendment are listed in Table 3.

4.2. Remedy Implementation The following remedial measures have been completed:

4.2.1. Groundwater Extraction and Treatment System VWP operated a groundwater extraction and treatment system intermittently beginning in 1980 until

July 2004. Following the issuance of the ROD in September l 991 , VWP continued groundwater extraction and treatment activities at the Site in accordance with the ROD. The groundwater extraction

and treatment system involved extraction ofcontaminated groundwater, above-ground treatment of extracted water with an electrochemical process to reduce the hexavalent chromium to trivalent chromium, followed by additional treatment using activated alumina to remove residual arsenic. The

treated groundwater was discharged into an infiltration pond on the VWP property where the water eventually seeped back into the subsurface.5

4.2.2. Ground Water Pilot Study The groundwater pilot study (GPS) approved by the 1994 ESD began on February 4, 1998. In the

GPS, contaminated groundwater was pumped from seven extraction wells along the axis of the hexavalent chromium plume, treated via the existing electrochemical precipitation system, then

amended with caJcjum polysulfide (a reductant) and reinjected into the groundwater through a series

ofwells along the plume's perimeter. The added calcium polysulfide reductant reacted with the hex.avalent chromil!.lm, in-situ, reducing it to the less toxic and less mobile trivalent chromium.

Residual calcium polysulfide from the in-situ treatment mobilized arsenic and manganese, and also

generated sulfate, temporarily and locally causing increased concentration of these contaminants in groundwater beneath the Site and down-gradient of the VWP property. Due to this increase in

manganese and sulfate concentrations above their respective secondary MCLs, they were identified as constituents of interest (COis) and their concentrations were monitored until 2012. This sampling was

4 EIPA. 2007. 5 EIPA. 1991.

Valley Wood Preserving Superfund Site Second Five-Year Review Report 15

ended because concentrations at domestic wells were well below the secondary MCLs and

concentrations at monitoring wells were either below secondary MCLs or at MCLs with either

declining trends or stable trends. Overall, the GPS was effective at essentially eliminating the

hexavalent chromill!m contamination plume. After 33 months of GPS operation, the hexavalent chromium concentrations in groundwater had been essentially eliminated, and EPA determined in July 2004 that the groundwater extraction system could be shut down in order to implement the soil

remedial action.6

4.2.3. Soil Excavation Soil remedial actions involving excavation and offsite disposal ofsoil with contaminant concentrations that exceeded the revised cleanup standards were completed in 2004. The Site was divided into seven

separate areas for excavation. Three areas were excavated to the groundwater table and four were excavated to 4 feet bgs. To determine whether all impacted soil was being removed, confirmation soil

samples were colle·cted intermittently during excavation. The excavation continued until the confirmation samples displayed hexavalent chromium and arsenic concentrations below the cleanup

criteria. In total, 3,216 cubic yards (c.y.) ofsoil were removed from seven excavation areas.7

4.2.4. In-situ Treatment and Monitored Natural Attenuation for Residual Groundwater Contamination

Pursuant to the second ROD amendment, in-situ treatment for arsenic in groundwater was completed

on October 8, 2007. The in-situ treatment was conducted in the area of residual arsenic contamination along the western side of the former VWP wood-treating facility. The evolution of the arsenic plume from 1998 to early 2006 illustrated the need for further treatment as there was little change in the

arsenic plume over that period of time. The additional in-situ treatment involved the injection of ViroBind™ F Blend reagent slurry (a product produced rrom clay with a high iron content) into

gridded injection points, covering an area rrom near monitoring well GW-24 to approximately 50 feet north of monitoring wells GW-1 and GW-12 (Figure 3, within red bracket). Virobind™ reagent has high metal binding properties along with the ability for acid neutralization. The technology has been

shown to be a viable and economical treatment solution for immobilization ofany heavy metal contaminants present in a non-leachable form. The Virobind1

"M reagent prevents leaching of heavy

metals by binding them as part of the formation ofnew chemically and physically stable mineral phases with very low solubilities.

The objective was to hydrofracture the subsurface, allowing for the creation ofa series of sub­horizontal fractures that would allow the reagent to migrate laterally away from injection points.

Sulfate, iron, and manganese concentrations increased significantly after the injections.8 Arsenic concentrations in the vicinity of the injection area dropped by as much as two orders ofmagnitude

following the in-situ treatment.

In addition to the in-situ treatment to address t he residual contamination at the Site, the second ROD amendment calls for monitored natural attenuation (MNA) following the in-situ treatment phase. Based on the focused feasibility study (FFS), EPA believed that natural attenuation would have

addressed residual hexavalent chromium and arsenic left in the groundwater, and concentrations would

Valley Wood Preserving Superfund Site Second Five-Year Review Report 16

continue to decrease with time.9 However, the last five years ofgroundwater monitoring data s show

increasing trends for hexavalent chromium and arsenic in several wells.

4. 3. Operation and Maintenance (O&M) No remediation (i.e., active treatment) system is currently operating at the Site. The groundwater extraction and treatment system ceased operation in July 2004 and has been dismantled, as the system

is no longer necessary. Groundwater monitoring under the MNA phase of the remedy is continuing at the Site pursuant to the groundwater monitoring plan (GMP) revised in December 2008.

Table 4 provides the total costs related to operation and maintenance of the Site since 1980. The costs include past remedies and sampling as well as annual land-use covenant inspections. Since that time cost ofoperation and maintenance has declined due to the reduction in remedial actions being

conducted ( 1980-2007) as well as a reduction in sampling and reporting (2008-2014 ).

5. Progress Since the Last Five-Year Review

5. 1. Previous Five-Year Review Protectiveness Statement and Issues

The protectiveness statement from the 2009 FYR for the Valley Wood Preserving lnc. Superfund Site stated the following:

"The remedies implemented at the VWP Site pursuant to the ROD and both ROD amendments are protective of human health and the environment. Confirmation soil sampling performed during the revised soil remedial action, selected in the 2003 ROD amendment, confirmed that soil cleanup

standards for chromium and arsenic in the unsaturated zone have been achieved. The institutional

controls (including the land use covenant) reqt1ired by the 2003 ROD amendment ensure that future use of the Site will be restricted to commercial and industrial ptLrposes. Implementation of the original

and the revised groundwater remedies has reduced the chromi um groundwater contamination plume to below MCLs for all monitoring wells offsite and also successfully reduced the areal footprint of the

arsenic contamination plume. The ongoing MNA phase of the groundwater remedy will monitor

progress toward achieving groundwater cleanup standards in the remaining small footprint of the

plume on the western VWP property line."

The 2009 FYR had no issues or recommendations.

5.2. Work Completed at the Site During this Five Year Review Period

Between September 22 -26, 2008, 32 Site wells were abandoned following the successful reduction of bexavalent chromium concentrations during the operation of the GPS (Figure 6). The completion of the Revised Groundwater Monitoring Plan (GMP) described the monitoring field requirements for the

MNA phase. This plan determined that a number of injection wells, recovery wells, and monitoring wells were no longer needed to complete the remedy; 32 wells total were no longer needed.Io The EPA approved the recommendation to abandon the wells on September 5, 2008.

In March 201 l three wells were abandoned; two monitoring wells and one former private water supply

wel I. A new vadose-zone well was constructed in the area of the VWP former groundwater pilot study.

Vadose-zone well GW-l 2V was constructed approximately halfway between the existing monitoring

well GW-1 and the abandoned well GW-12. The purpose of the newly constructed well was to check for migration ofperched water from the base of the nearby backfilled soil-excavation area, and to

obtain samples ofground water during periods of high water-table conditions.

6. Five-Year Review Process

6. 1. Administrative Components

EPA Region 9 injtiated plans for the Valley Wood Preserving FYR in 2013 and scheduled its completion for September2014. The review team consisting ofBlair Kinser (environmental engineer)

and Katie King (geologist) from the USACE Seattle District was led by Marie Lacey ofRegion 9 EPA, Remedial Project Manager (RPM) for the Valley Wood Preserving Inc. Site. On December 18, 2013,

EPA held a scoping call with tlhe review team to discuss the Site and items of interest as they related to

the protectiveness of the remedy currently in place. A review schedule was established that consisted of the following:

• Community notification;

• Document review;

• Data collection and review;

• Site inspection;

• Local interviews; and

• Five-Year Review Report development and review.

6.2. Community Involvement

On March 27, 2014 a public notice was published in The Modesto Bee announcing the commencement

of the Five-Year Review process for the Valley Wood Preserving Inc. Site and inviting community participation. The public notice is available in Appendix B. EPA did not receive any calls as a result of

this notice.

The Five-Year Review report will be made available to the public once it has been finalized. A copy of

this document will be placed in the designated local public repository: Stanislaus County Library, 550 N. Minaret Avenue, Turlock, California. Copies will also be available at the EPA Records Center, 95 Hawthorne Street, San Francis·co, California and online at www.epa.gov/region09NalleyWood.

6.3. Document Review

This FYR included a review of relevant, site-related documents including the 1991 ROD, 2003 ROD

amendment, 2007 ROD amendment, remedial action reports, well abandonment reports, correspondences between VWP and the EPA, and recent monitoring data. A complete list of the documents reviewed can be found in Appendix A.

ARARs Review

Section 121 (d)(2)(A) ofCERCLA specifies that Superfund remedial actions (RAs) must meet any

federal, or more stringent state, environmental standards, requirements, criteria, or limitations that are deterrruned to be Applicable or Relevant and Appropriate Requirements (ARARs). ARARs are those

standards, criteria, or limitations promulgated under federal or state law that specifically address a hazardous substance, pollutant., contaminant, RA, location, or other circumstance at a CERCLA site.

Valley Wood Preserving Superfund Site Second Five-Year Review Report 21

Chemical-specific ARARs identified in the selected remedy within the ROD and subsequent ESD and ROD Amendments for the groundwater at this Site and considered in this FYR for continued groundwater treatment and monitoring are listed in Table 5. Cal ifornia primary drinking water standards are the same as federa l primary drinking standards except for the California standard (50 µg/L) for total chromium, which was more stringent than the federal standard (100 µg/L). The more stringent of the two concentrations mentioned above (Cal ifornia Standards) was determined to be the cleanup level for the Site. On May 28, 2014 the State ofCalifornia amended Title 22 CCR §64413 to add hexavalent chromium to its regulated chemicals list, which became effective on Ju ly I, 2014. The new MCL is 10 µg/L. The State MCL for total chromjum remains unchanged.

Human Health Risk Assessment Review

A human health risk assessment was completed for the Site in 1991 and summarized in the ROD. It

considered both continued industrial use and hypothetical future residentia l use of the Site. The risk assessment identified the following exposure pathways: domestic use ofgroundwater, dermal contact

with groundwater and soil, and soil dust inhalation for both children and adults onsite and offsite. The

risk assessment was reviewed to identify any changes in exposure or toxicity that would impact protectiveness.

Valley Wood Preserving Superfund Site Second Five-Year Review Report 24

Soil: The risks associated with the exposure pathways established for soil in the 1991 ROD are no

longer present. Soil remedial actions, along with the land use covenants (LUCs) that limit the land use

to industrial purposes only, have removed the risk related to dermal contact, soil ingestion, and soil inhalation. The soil excavation performed in 2004-2005 removed contaminated soil so that remaining

concentrations are below the industrial cleanup levels of4 mg/kg for hexavalent chromium and 25 mg/kg for arsenic.

Groundwater: The exposure pathways identified in the ROD and ROD amendments for groundwater are

still valid. However, exposure via oral intake and dermal exposure has been li mited or eliminated with LUCs that prevent the installation ofdrinking water wells. In addition, remedial actions at the Site have

reduced concentrations ofarsenic and chromium in groundwater to below cleanup levels in the majority of Site wells.

No additional exposure pathways were identified during this five-year review.

Vapor Intrusion: EPA's understanding ofcontaminant migration from soi l gas and/or groundwater into

buildings bas evolved over the past few years leading to the conclusion that vapor intrusion may have a greater potential for posing risk to human health than assumed when the ROD was prepared. Vapor

intrusion is not an exposure pathway at the VWP Site because the COCs at this Site are arsenic and chromium, which are not volatile organic compounds and do not vaporize under standard temperature

and pressure.

Toxicity values: EPA's Integrated Risk Information System (IRIS) periodically updates chemical specific toxicity profiles as sufficient new infonnation becomes available. IRIS was used as the primary reference for new toxicity values. However, California' s Office of Health Hazard Assessment

(OEHHA) also produces similar chemical toxicity reviews that are applicable in the state. These were used if they are significantly more health protective. Using the updated toxicity values, EPA periodically updates the Regional Screening Levels (RS Ls) using risk assessment guidance from the

EPA Superfund program. They are risk-based media concentrations derived from standardized equations combining exposure information assumptions with EPA toxicity data. The cancer RSL is

based on a 10·6 excess cancer risk which is at the lower limit in EPA ' s acceptable risk management range of 10-4 to 1 o-6 excess cancer risk.

Valley Wood Preserving Superfund Site Second Five-Year Review Report 25

In 2010, EPA updated its Regional Screening Levels (RSLs) for hexavalent chromium. The RSL update

was based on a revised toxicity assessment by the New Jersey Department ofEnvironmental Protection

that used new toxicity information from the National Toxicology Program. The current hexavalent

chromium RSL for tap water ingestion is 0.031 µg/L. The U.S. EPA IRIS program is conducting its own re-assessment of the toxicity ofhexavalent chromium and EPA has committed to revising the chromium MCL upon completion of the IRIS re-assessment.

Ecological Review

The 1991 ROD determined that aquatic communities were unlikely to be affected by contaminants originating from YWP. The ecological risk assessment also found that there were no wetlands or

watercourses in the immediate vicinity of the Site. The contaminated groundwater under the Site did not and still does not discharge into any nearby watercourses. Since the 1991 ROD ecological risk

assessment, there have been no changes in ecological risks or exposure pathways. There also have been no changes to land use on and adjacent to the Site.

6.4. Data Review

6.4.1 Groundwater Groundwater elevations were collected between 2009 through 2014. This data indicated that significant

changes have occurred during hydrological events such as El Nino or the current 2013-2014 drought. The most significant changes to groundwater elevations occurred in 2011 and 2014. ln 2011 the average

increase of 1.66 feet was seen for the well with concentrations above cleanup levels. In 2014 the

average decrease was 1.46 feet

There is a concern that the increasing chromium concentration trends (as discussed further on) may have

had a correlation with the recent drought.

Groundwater concentration data collected from 2009 through 2013 was reviewed as a part of this FYR.

Samples collected from 10 domestic wells and 9 monitoring wells in 2009 to 2013 were analyzed for

Valley Wood Preserving Superfund Site Second Five-Year Review Report 26

arsenic and chromium. From 2007 to 2010 samples were collected on a quarterly basis. The sampling

frequency was decreased in 2010 to semi-annual and decreased in 2011 to annual, based on the

determination that in-situ remediation had reduced groundwater contamination significantly.

Groundwater levels were measured at 11 monitoring wells. Potentiometric maps from past Annual Ground Water Reports (AGWR) show that groundwater tends to flow toward the southwest.

Data collected between 2009 and 2013 were used to identify wells with contaminant concentrations above the cleanup levels. Table 8 displays the wells with concentrations exceeding the cleanup levels,

the concentration ranges, whether they were above the 95% Upper Confidence Level, and the contaminant that was above the c leanup level:

*Indicates that the last series of samples were above clean up levels

Data shows that concentrations in seven ofthe nineteen wells had exceeded the cleanup level between the years of2009-2013. Note that none ofthese wells were offsite domestic wells. Of the seven wells,

two had concentrations exceeding the arsenic cleanup level and six had concentrations exceeding the total dissolved chromium cleanup level.

Although not a chemical ofconcern identified in the ROD, groundwater samples were also tested for

hexavalent chromil!lm. Based on the annual sample results from 2013, total chromium concentrations are almost identical to the hexavalent chromium concentrations indicating that the predominant form of

total chromium present at the site is the hexavalent form. Six wells contain hexavalent chromium exceeding the new State MCL of IO µg/L: GW-390 , GW-l 5A, GW-l 5B, GW-l 5C, GW-5 and J-37. The concentrations in these wells ranged from 41 µg/L to 90 µg/L.

Valley Wood Preserving Superfund Site Second Five-Year Review Report 27

Samples were also analyzed for contaminants of interests (sutifate and manganese). The ROD specifies a

goal ofa "stable and decreasing concentration trend" for these contaminants of interest. Sulfate was

detected in all nineteen wells sampled, at concentrations ranging from 4.8 mg/L to 300 mg/L. Sulfate

has a secondary maximum contaminant level (SMCL) of250 mg/L. At the end of the pre- and post­ViroBind™ Injection analysis in January 2012, three wells had concentrations above the 250 mg/L SMCL for sulfate. The concentrations were 300 mg/L, 280 mg/L, and 274 mg/L for 1-37, GW-1 , and

GW-2 respectively. Two wells (GW-2 and GW-24) exhibited concentrations ofmanganese above the

secondary drinking water standard of0.05 mg/L. These wells are in the area of previous in-situ Activated Red Mud (ARM) treatment for arsenic remediation. The injected reagent contained ferrous ions (in the form offerrous chloride) with mi11or amounts ofmanganese, and these increases were

expected. The remaining wells. sampled did not exhibit manganese above the detection limit of 0.02 mg/L. In December 20 12, EPA approved the deletion ofsulfate and manganese from the GMP because data indicated stable or decreasing trends at all the wells sampled for these COis.

6.4.2.1 Groundwater Mann-Kendall trend analysis To determine the trends ofconcentrations in the wells identified in Table 8 data was analyzed using the

Mann-Kendall tests through the use of the MAROS software application. The results of the statistical analysis are seen i111 Table 9.

The Mann-Kendall Result pages from MAROS and trend analysis figures can be viewed in Appendix G.

The trend analysis determined that six of the seven wells had a trend that was increasing or probably increasing (90% confidence or above). However, the data shows a fairly stable concentration trend with

a jump in concentrations in 2012. These elevated concentrations were verified in the 2013 event.

The data analysis concludes that the remedy has worked for the majority of the wells. However, for wells GW-1 , GW-15-NB/C, GW-5, and 1-37 additional monitoring and analysis is warranted. The jump

in chromium concentration could be attributed to the variatiol!l of the ground water elevation, or other

geochemical changes. The use ofActivated Red Mud as the remedy may have been affected by the

Valley Wood Preserving Superfund Site Second Five-Year Review Report 28

changes to the temperatures and pH of the water as the water level fluctuated causing the absorptive

characteristics of the Activated Red Mud to increase (increase in temperature and pH) or decrease. In addition the original soil may be leaching additional chromiwn ion into the water surpassing the

absorptive capacities of the injected Activated Red Mud.

6.5. Site Inspections

The site inspection was conducted on January 24, 2014. The attendees of the site inspection included:

Marie Lacey (RPM, EPA), Bob Schmidt (Owner), McKinley Lewis (DTSC), Rick Thomasser (VWP), Ellen Engberg (USACE), and Blair Kinser (USACE). The agencies, phone numbers, and emails of the attendees are presented in Appendix D.

The site inspection lasted approximately one hour and consisted ofa walk around the Site and

discussion among the attendees detailing the specifics of general locations ofactive wells and their overall condition with regard to sampling results and physical conditions. Other topics discussed

included the surrounding neighborhood, security and fencing, and other aspects that could affect groundwater conditions and sampling results. Upon conclusion of the site inspection a site inspection

checklist was completed and can be seen in Appendix D.

The Site was well maintained with fencing in good condition. The wells were easily identified as either

active or abandoned. The property owner Bob Schmidt and the owner' s consultant Rick Thomasser

were helpful in helping the other attendees understand the Site conditions and what they believe should

be the future proceedings for the Site. No LUCs were noted to be violated.

6. 6. Interviews

The first interview was conducted with Bob Schmidt (Owner) and Rick Thomasser (MWH consultant) on January 24, 2014 immediately after the Site visit and completion of the site inspection checklist.

They noted no problems with institutional controls other than the occasional cutting of the fence and trespassing. They mentioned no problems with the construction of the remedy but did note their desire to abandon a few wells as documented in the groundwater monitoring report. They mentioned no

unusual situation or problems at the Site.

The second interview with McKinley Lewis of DTSC was conducted on February 2I , 2014 over the phone. In general, Mr. Lewis was positive about how the Site has been remedied, the communication with EPA and VWP, and the professionalism of those involved. Specifics of the interview are in

Appendix C.

6. 7. Institutional Controls

ICs are non-engineered instruments that minimize the potential for human exposure to contaminants,

limit land use, and/or protect the integrity ofthe remedy. At the Site, I Cs were implemented to prohibit

residential use of the VWP property, including a zoning change and recording ofa land use covenant.

The zoning change (to "planned industrial" use) was approved by the Stanislaus County Board of

Supervisors in 2005, and ensures that the Site will not be converted into a use that would increase

exposure.

Valley Wood Preserving Superfund Site Second Five-Year Review Report 29

The Land Use Covenant was finalized in June 2007 and recorded with the Stanislaus County Recorder

Office on June 22, 2007 (VWP, 2007). The Covenant is between VWP, and DTSC, with EPA as a third

party beneficiary. The Covenant restricts future uses of the property to industrial and commercial use

only and specifically prohibits using the property for the fo llowing purposes: residence; hospital for humans; public or private school for persons under 21 years ofage; day care center for children; long­term care facility for the elderly, handicapped or infirm; and any other purpose involving residential

occupancy on a 24-hour basis.

The terms of the Covenant require an annual inspection of the property, as well as an annual report prepared by the owners of the property that describes how all the requirements outlined in the covenant

are being met. On an annual basis the Site is inspected by VWP representatives and/or DTSC for compliance with the land use restrictions and the findings are sent to DTSC in an Annual Inspection Report. In each of the reports, from the past five years, VWP reported that the Site was in compliance

with the Covenant. In each report DTSC accepted the annual report as written.

The !Cs have been properly implemented as verified by Bob Schmidt and McKinley Lewis (Table I 0).

A title search was conducted and shows that the Land Use Covenant was recorded. The title search is

presented in Appendix I.

7. Technical Assessment In this section all items in the checklist, as seen in Appendix D, ofthe Comprehensive Five-Year

Review Guidance are reviewed via questions and discussion.

7.1. Question A: Is the remedy functioning as intended by the decision documents?

Yes, the remedy has fully functioned as intended. Monitoring data has shown significant reduction in contamination and concentrations below clea11up levels; however, six wells with concentrations above

cleanup levels have had an increase in concentration since 2012. Therefore, further monitoring and analysis is warranted. The risk ofexposure to chromium and arsenic has been reduced to acceptable levels due to the remedy and institutional controls implemented at the Site.

Remedial Action Performance

Excavation and offsite disposal of soil contaminated by the wood treating process at VWP, conducted in 2004, was effective in reducing the migration of contaminants from soil to groundwater. Jn addition,

excavation and treatment was conducted between 1980 and 2004. This further reduced tbe possible spread of the arsenic and chromium plume into domestic wells to the southwest of the Site. Since 2004

no other source removal has been conducted.

Currently no active remedy is being conducted and monitored natural attenuation is ongoing. Monitoring includes the sampling of 19 wells for arsenic and chromium. Both domestic and monitoring wells were also sampled for Sllllfate and manganese between 2008 and 2012. EPA approved the deletion

ofsulfate and manganese from the GMP because concentrations at the domestic wells were far below the secondary MCLs and the concentrations at the monitoring wells were either stable or decreasing below the secondary MCLs.

Groundwater data indicate that contaminant concentrations at the Site are approaching cleanup levels.

Most wells have shown sharp declines in chromium and arsenic concentrations (see trend analysis in Appendix H), possibly indicating that areas ofhigh hydraulic conductivity were remediated to levels below the MCLs specified in the ROD. However, there may be localized low hydraulic conductivity

areas on the Site where the ViroBind1 "M injections may not have been as effective. Wells GW-1, GW­

1 SA/B/C, GW-5, and 1-37 contain concentrations that remain above cleanup levels. Well GW-390 has

consistently had chromium and arsenic concentrations above c leanup levels. This well may have been improperly constrll!cted and was rehabilitated in 2003. However, it may be a potential pathway for

vertical migration of contaminants.

System Operations/O&M

The Site is currently at the MNA stage. Seven wells had concentrations above the cleanup standards. Continued monitoring should be conducted at the Site to determine if these wells will reach

concentrations below the cleanup levels specified by the ROD.

Valley Wood Preserving Superfund Site Second Five-Year Review Report 31

Based on discussion with the property owner Bob Schmidt and VWP consultant Rick Thomasser it

appears there have been no significant variances in the operations and maintenance (O&M) costs that

would indicate a remedy problem or issue.

Op[portuoities for Optimization

Opportunities exist for improving performance or reducing monitoring costs:

• EPA approved the abandonment ofWells GW-2 and GW-12V; however, these wells have not

yet been abandoned by VWP.

• Sampling at the domestic wells could be considered for suspension. During the past five years, arsenic and total chromium have never been detected in domestic wells at concentrations above

the cleanup levels.

Other monitoring optimization recommendations that were considered include:

• Well P-5 has been recommended for abandonment by VWP. The well has consistently had concentrations below detection levels. EPA approved the suspension ofchemicaI data collection

from this well in 20 l l , but required continued annual water level monitoring. EPA has not

approved abandonment of this well because of its location as the only remaining well downgradient from Well l-37. T he well, due to its location in the area of the mid plume of 1991 ,

should be left to function as a check for any possible plume movement that could occur between wel ls.

• Well GW-5 was also recommended fo r abandonment by VWP, but EPA did not approve it. Concentrations are increasing in this well, and it shou ld not be abandoned.

7.2. Question B: Are the exposure assumptions, Toxicity Data, Cleanup Levels, and Remedial Action Objectives (RAOs) Used at the Time of Remedy Selection Still Valid?

Yes. Some of the exposure assumptions, toxicity data, c leanup levels, and RAOs have changed in the past five years; however, these changes do not call into question the protectiveness of the remedy. The standards are still val id since the 2007 ROD Amendment. However, the State ofCalifornia has recently

adopted an MCL for hexavalent chromium. T he institutional controls that are in place also ensure that the land use is limited and that onsite groundwater cannot be used for drinking water or other uses that could interfere with Site remediation. No new human health or ecological routes ofexposure or

receptors have been identified since the last FYR. In addition, no new contaminants or contamination sources have been :identified. There were no unanticipated toxic byproducts.

Progress towards the RAOs has been positive since the excavation (2004) and electrochemical (2007)

remedial activities have been conducted. However, wells with contamination levels above the ROD standards may require additional monitoring and evaluation. T he Site cleanup is progressing as

expected.

Valley Wood Preserving Superfund Site Second Five-Year Review Report 32

7.3. Question C: Has Any Other Information Come to Light That Could Call Into Question the Protectiveness of the Remedy?

No additional ecological risks have been ident ified. No impacts from natural disasters have affected the protectiveness or activities of the Site. No addlitional information has come to light which would affect the protectiveness of the remedy.

7.4. Technical Assessment Summary

The remedy is functioning as intended. Past remedial actions have reduced contaminant concentrations to levels below ROD cleanup levels for the majority of the wells. However, further assessment may be needed to determine the reason for the elevated concentrations at several wells. The exposure assumptions, toxicity data, cleanup levels, and RAOs have not changed in the past five years. The State ofCalifornia has recently adopted a new MCL for hexavalent chromium. No additional ecological risks have been identified. No impacts from natural disasters have affected the protectiveness or activities of the Site. No additional information has come to light which would affect the protectiveness of the remedy. The Site is maintainin g LUCs.

In addition, recommendations that improve the effectiveness of the remedy, reduce costs, provide technical improvement, improve management of O&M, accenerate site close out, or improve energy

conservation and sustainability, but don't affect current protectiveness, that were identifi ed during this Five-Year Review are as follows:

• Evaluate the need to sample monitoring wells that have had concentrations below the cleanup levels (except P-5) and domestic wells. Reduce sampling frequency where deemed appropriate.

10. Protectiveness Statement The remedy at Valley Wood Preserving Superfund Site currently protects human health and the environment becaUJse land use controls have been implemented and enforced to ensure exposure to

contaminant concentrations above the MCL is eliminated as well as prohibiting residential use at the Site, which has been remediated only to soil cleanup levels. However, in order for the remedy to be

protective in the long term, an evaluation should be conducted to assess the reason for the elevated concentrations at several wells and to determine if the current remedy can achieve the new hexavalent chromium standard. Also, an Explanation of Significant Differences should be issued to select the new

State MCL as a groundwater Cleanup standard for the Site.

11. Next Review This Site is subject by CERCLA to ongoing FYRs as long as waste is left onsite that does not allow for

unlimited use and unrestricted exposure. Therefore, assuming waste remains in place, the next FYR for this Site should occur in 2019 five years after the issuance of this Report.

Summary of Conversation

1) What is your overall impression of the project?

We are in the final stage and this is a mature site. The frequent monitoring has had no surprises in data.

We see a slow declining trend. We do have concerns with the possible changes with the clean up levels of the state MCLs. This is a family business and this would incur additional cost.

2) Is the remedy functioning as expected? How well is the remedy performing?

The remedy is doing well. MNA is working well but we would like to have it move faster. With current efforts we suspect the site should be meeting cleanup levels - a~though lack of rainfall this year may cause some changes to the data. This may cause an increase in the sulfate reading in due to the nearby

agricultural processes. Trending data is hard to have a real accurate trend line due to the limitation on detection.

3) What does the monitoring data show? Are there any trends that show contaminant levels are decreasing?

Annual reports show trends analysis on each well for arsenic and chromium. There are a few wells above but most are trending downward. Contingent to speed up the clean up process may be poly sulfite to speed the process up. No rain this year may cause changes in data and trends.

4) Is there a continuous O&M presence? If so, please describe staff and activities. If there is not a continuous on-site presence, describe staff and frequency of site inspections and activities.

Another person does come on site once a week while I (Bob Schmidt) make a visit once every week or every other week.

5) Have there been any significant changes in the O&M requirements, maintenance schedules, or sampling routines in

the last five years? If so, do they affect protectiveness of the remedy? Please describe changes and impacts.

We have gone to annual reporting and sampling. Prior to 2009 we were doing quarterly. From 2009 to

2011 we were doing twice annually. Well abandonment occurred in 2010 and 2011 a few wells have been removed from the sampling events. This has no effect on the remedy and to conduct semi-annual sampling will not impact the remedy as well.

Second Five-Year Review Report, Valley Wood Preserving Superfund Site 45

6) What are the annual operating costs for your organization's involvement with the site?

GW sampling and reporting cost $7,400.00 other cost to be kept in house.

7) Have there been unexpected O&M difficulties or costs at the site in the last five years? If so, please give details.

None.

8) Have there been opportunities to optimize O&M or sampling efforts? Please describe changes and resultant or desired cost savings or improved efficiency.

Each year provide a report on increasing efficiency and decreasing cost. Wells that can be abandoned ­

GW39D and P-5 just to name a few because they do not add to data. We agree with standards and once met wells should be abandoned.

9) Are you aware of any changes in Federal/State/County/Local laws and regulations that may impact the protectiveness of the remedy?

There is a pending change to the hex chrome regulation; we don't believe this will affect the remedy.

10) Do you have any comments, suggestions, or recommendations regarding the project?

We are in MNA mode but being part ofa superfund site cost significant amount of money; in particular

oversight costs is larger than the cost of the wor k actually being done. We want things to be more efficient

Oversight cost is ast ronomical a nd is significant for out of pocket cost for a family owned business.

Additional Site-Soecific Questions 1. What was the total volume ofgroundwater treated?

This has been documented but we believe it is around 10 million gallons ofwater has been treated.

2. Are there are plans for the future use of the site?

There are ­ We are currently conducting a feas ibility s tudy for a truck parking facility.

Summarv of Conversation

Interview Questions

1. What isyour current role as it relates to the site? What isyour overall impression ofthe work conducted at the site to date? (general sentiment)

I am a Project Manager for DTSC overseeing Operations and Maintenance for the VWP site since 2009. The work has been very professional and well done. The data shows that the remedies have

been successful at protecting human health and the environment at the site. Valleywood Preserving has been interacting well.

2. Have there been routine communications or activities (site visits, inspections, reporting activities, etc.) conducted byyour office regarding the site? Ifso, give purpose and results.

Yes there has been routine communication.. I hear from Bob Schmidt (VWP) periodically, contacts me when he receives the cost recovery invoices, he likes to have daily logs of the invoices. We also

receive contact from EPA when there is an issue or request from RP when input is requested. Also have had contact for the S year review, this is my second 5 year review on the site. We also

communicate on the yearly land use covenant inspection. Mr Scmidt does the inspection, and DTSC does a follow up inspection. (McKinley will provide Blair with dates ofany other site visits between 2009 and now).

3. Areyou aware ifthe site has been in compliance with permitting or reporting requirements?

Yes I am, just spoke with the lot, a yearly inspection is required and it is determined that the property is in compliance. No residences, no school, daycare centers, daycare for elderly. Property

has been zoned, was rezoned in 2005 prohibiting residential use. Annual reporting has always been on time, no major issues the findings. A few blips here and there that we keep an eye on.

4. Have there been any complaints, violations, or other incidents related to the site requiring a response byyour office? Ifso, please give details ofthe events and results ofthe responses.

No, not during the past 5 years, not that I am aware of.

Second Five-Year Review Report, Valley Wood Preserving Superfund Site 47

5. Has any individual contacted you voicing questions or concerns about the site?

No.

6. Doyou feel well informed about the site's activities and progress?

Yes, very much so. Marie has been very good, keeping me .aware ofany situations at the site, or the RPs request to change the remedy, or cost estimate they just commented on. Marie: the main issue is the repeated request to abandon certain wells, for some of them it's just not time yet. McKinley: I don't like to move that quick, we are all for moving the project forward and complete it as timely as possible. But the repeated requests to abandon wells. Otherwise, Bob's been good, the reports are

on time, compiled with requests and restrictions, followed the program.

7. Areyou aware ofany changes in State/County/Local laws and regulations that may impact the protectiveness ofthe site?

Yes, California department of public health announced they will change the MCL for hex chrome to 10 ppb. The public comments closed in October, I just checked the website today, and they haven't posted anything fina l yet. But it's in the works, change from 50 ppb to 10 ppb.

8. Doyou have any comments, suggestions, or recommendations regarding the site's management, operation, or any other aspects ofthe site

Up to this date, both departments have done an excellent job, very professional, on the same page. I wouldn't change a thing.

XI. OVERALL OBSERVATIO NS

A. I mplementatio11 of the Remedy

Describe issues and observations relating to whether the remedy is effective and functioning as designed. Begin with a briefstatement ofwhat the remedy is to accomplish (i.e., to contain contaminant plume, minimize infiltration and gas emission, etc.).

The selected remedy was designed to cleanup the groundwater plume. Cleanup is near complete after in-situ bioremediation. The active remediation has been shut down, and monitored natural attenuation continues to show decreasing trends.

B. Adequacy of O&M

Describe issues and observations related to the implementation and scope ofO&M procedures. In particular, discuss their relationship to the current and long-tem1 protectiveness of the remedy.

O&M is minimal since cleanup is near complete and active treatment has ceased. Annua I monitoring is adequate for monitored natural attenuation.

c. Early I ndicator s of Potential Remedy Problems

Describe issues and observations such as unexpected changes in the cost or scope ofO&M or a high frequency ofunscheduled repairs, that sugge.~t that the protectiveness of the remedy may be compromised in the future.

None identified during site visit.

D. Oppor tunities for Optimization

Describe possible opportunities for optimization in monitoring tasks or the operation of the remedy.

None identified during site visit.
