Attached for your signature is the second Five-Year Review Report for the Limestone Road Superfund Site (Site) located south of Cumberland in Allegany County, Maryland.

The remedy for the Limestone Road Superfiind Site in A'llegany County, Maryland included: installation of a multilayer caps over contaminated soils at two landfills and installation of a public water line to 19 residences impacted by Site groundwater. The fences around the landfills restrict access. Institutional controls, which alert prospective buyers of contaminants on-site and place prohibitions on future development, have been implemented for the Diggs and CC&SC properties. In addition, a Groundwater Management Zone prohibits the installation of new groundwater wells in the vicinity of the Site. This is the second five-year review for the Site. The trigger for this five-year review is the signature date of the previous Five-Year Review report, January 19, 2006. The purpose of a Five-Year Review is to ensure Ithat the cleanup remains protective of human health and the environment and is functioning as designed.

The Site remedy is protective of human health and the environinent in the short-term because the remedial actions selected in the RODs for OU11 and 0U2 were implemented and all immediate threats at the Site have been addressed. However, this Five Year Review found that two of the nineteen residences that were connected to the public water supply have had their public water turned off. Nonetheless, it should be noted that the maximum concentrations of contaminants detected at these two residences (identified as sample locations DW-OOl and DW-014 in the RI/FS) were both below MCLs in sample analyses performed during the RI/FS. Moreover, current data (2010) collected ,from monitoring wells located dovmgradient of the landfill and iipgradient of the homes indicate that the manganese concentrations have dropped below risk based concentrations. Long-term protectiveness will be verified during the next sampling event. "

In addition, although concentrations of cadmium and lead in sediment were just above BTAG screening levels in recent sampling, an inspection of the unnamed stream

t 3 Printed on 100% recycled/recyclable paper with 100% post-consumer fiber and process chlorine free. Customer Service Hotline: 1-800-438-2474

by a BTAG specialist concluded that the stream supports macroinvertibrates that are indicative of moderately clean water. Thus, the remedy the remedy appears to be protective of the environment.

Further information will be obtained by taking the following actions:

Determine the reasons for the cancellation of public water supply service at two of the residences located downgradient of the Site. If possible, collect a groundwater sample from each of the wells for Site COC analysis.

Replace missing or damaged sighs; clear vegetation fi-om the perimeter fence line; mow/brush hog the landfill cap and perimeter fencing; and change the timing of mowing and brush hogging the landfill cap and around perimeter fencing from "After the First Killing Frost" to mid-November.

The following are operation and maintenance recommendations related to issues which del not affect current or fijture protectiveness identified during the Five-Year Review:

EPA will review the monitoring well abandonment plan and determine which wells should remain for long term monitoring of the Site. Abandonment of designated monitoring wells will be completed before the next Five-Year Review

I

It is expected that these issues and actions will be implemented by the end of June 2011. The information, actions and results will be documented in the next (3rd) Five-Year Review.

Executive Summary

The Limestone Road Superfiind Site (Site) is located in Allegany Countly, approximately 2.5 miles southeast of the City of Cumberland, Maryland. The Site consists of two parcels of land: the 20-acre former Diggs Sanitafion Company property (Diggs) and the 190-acre Cumberland Cement and Supply Company (CC&SC) property. The Diggs property is bordered on the southwest by several residences and to the northeast by the former Cumberland City Dump and undeveloped land. The CC&SC property is bordered to the northwest by the former Cumberland City Dump and Limestone Road, and undeveloped land on the remaining perimeter of the property. There are 19 residences downgradient of the Site that had previously obtained drinking water from individual water supply wells prior to EPA's involvement at the Site.

The selected remedies for the Limestone Road Superfund Site included, among other things: installation of multilayer caps over the contaminated soils at the two landfills, installation of a water line to connect the 19 residences impacted by the Site to the public water supply system, and institutional controls (ICs) to prohibit the installation of drinking water wells in the vicinity of the Site. Allegany County created a Groundwater Management Zone which prohibited installation of new groundwater wells in the vicinity of the Site at the time of the water line construction. However, some of the residents challenged EPA's decision to permanently destroy their existing wells, citing plans to potentially use their groundwater resource for purposes other than potable water. EPA determined that it did not have the authority to require the abandonment of private residential wells and, on September 27, 2000, issued a Memorandum of Minor Change to the 0U2 Record of Decision (ROD) which removed this requirement from the 0U2 ROD remedy. Allegany County then offered jhomeowners the opportunity to connect to the public water supply at the expense of the Potentially Responsible Parties (PRPs) and required them to abandon their existing residential wells as a condition to the connection to the public water supply.

In addition, the PRPs filed notices on the deeds for the Diggs and CC&SC properties which provide notice that groundwater use is restricted and those activities tha!t would interfere with or damage the integrity of the caps for each of the two properties are prohibited.

The trigger for this Five-Year Review is the signatiire date of the previous Five-Year Review Report January 19, 2006. The purpose of a Five-Year Review is to ensure that the cleanup remains protective of human health and the environment and is flinctioning as designed.

Protectiveness Statement

The Site remedy is protective of human health and the environment in the short-term because the remedial actions selected in the RODs for OUl and 0U2, were implemented and all immediate threats at the Site have been addressed. However, this Five Year R'eview found that two of the nineteen residences that were connected to the public water supply have had their public water turned off Nonetheless, it should be noted that the maximum concentrations of contaminants detected at these two residences (identified as sample locations DW-OO1 and DW-014 in the RI/FS) were both below MCLs in sample analyses performed during the RI/FS. Moreover, current data (2010) collected from monitoring wells located downgradient of the

landfill and upgradient of the homes indicate that the manganese concentrations have dropped below risk based concentrations. Long-term protectiveness will be verified during the next sampling event.

In addition, although concentrations of cadmium arid lead in sediment were just above BTAG screening levels in recent sampling, an inspection of the unnamed stream by a BTAG specialist concluded that the stream supports macroinvertibrates that are indicative of moderately clean water. Thus, the remedy the remedy appears to be protective of the environment.

1. As part of the Limestone Road remedy, a public water system was installed for residents that were located downgradient of the Site. Two of the residents have had their public water Isupply either turned off or requested that the water be turned off. However, residential well sampling performed during the RI/FS indicated that the maximum concentrations of contaminants detected at these two residences were below both MCLs and action levels.

2. Site inspections revealed that several signs were missing or damaged along the perimeter fencing; some areas of perimeter fencing were too overgrown to observe fencing and potential burrow holes; and the Site'has not been mowed and brush hogged.due to early season snow.

Recommendations:

1. Determine the reasons for the cancellation of public water supply service at two of the residences located downgradient of the Site and the source of potable water being iised by the residences. If groundwater is being used as a source of drinking water, collect a groundwater sample from ekch of, the wells for Site contaminant of concern (COC) analysis.

2. Replace missing or damaged signs; clear vegetation from the perimeter fence line; mow/brush hog the landfill cap and around perimeter fencing; and change the timing of mowing and brush hogging the landfill cap and around perimeter fencing from "After the First Killing Frost" to mid-November.

Five-Year Review Report For

Limestone Road Superfund Site Cumberland, Allegany County, Maryland

I. Introduction

The purpose of the Five-Year Review is to determine whether the remedy at a Site is protective of human health and the environment. The methods, findings, and conclusions of reviews are documented in Five-Year, Review Reports. In addition, Five-Yeari Review Reports identify issues found during the reviews, if any, and recommendations to address them.

The United States Environmental Protection Agency (EPA) is preparing this Five-Year Review Report pursuant to §121 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and the National Oil and Hazardous Substances Pollution, Contingency Plan (NCP). CERCLA §121 states: I

r J

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 the initiation of such remedial action to assure that human health and the environment are being protected by the remedial action being implemented. In addition, if upon such review it is the judgment\of the 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 list of facilities for which such review is required, the results of all such reviews, and any actions taken as a result of such reviews. !

The Agency interpreted this requirement ftirther in the NCP; 40 Code of Federal Regulations ' 300.430(f)(4)(ii) 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 action no less five years after the initiation of the selected remedial action.

often than every

The United States Environmental Protection Agency, Region 3, conducted the Five-Year Review of the remedy implemented at the Limestone Road Site in Allegany County, Maryland. This review was conductedby the designated Remedial-Project'Managers (RPMs) for the entire Site from October 2007 through January 2011. This report documents the results of the review.

This is the second Five-Year Review for the Site. The first Record of [Decision (ROD) was issued September 30, 1986 which was before the Superfimd Amendments and Reauthorization Act (SARA) was issued. Therefore, the initial triggering action for this policy review is the Preliminary Close Out Report (PCOR) dated September 28, 2000. The first Five-Year Review was completed January 19, 2006. Five-Year Reviews are required due to the fact that hazardous substances, pollutants, or contaminants remain at the Site above levels that allow for unlimited use and unrestricted exposure.

III. Background

Physical Characteristics and Land Use

The Limestone Road Site is located in Allegany County, approxiinately 2.5 miles southeast of the City of Cumberland, Maryland (Figure 1). The Site consists jbf two parcels of land: the 20-acre former Diggs Sanitation Company property and the 190-acre Cumberland Cement and Supply Company property. The Diggs property is bordered on the southwest by several residences arid to the northeast by the former Cumberland City Dump and undeveloped land. The CC&SC property is bordered to the northwest by the former Cumberland City Dump and Limestone Road, and undeveloped land on the remaining perimeter of the [property (Figure 2). All 19 residences located within a half mile of the Site had previously obtained drinking water from individual water supply wells prior to EPA's involvement at the Site!

• The Diggs property was utilized for un-permitted refiise operations from the late 1960's through the early 1980's. The primary operation was the landfilling of commercial, residential and demolition wastes. The CC&SC property, formerly a limestone quarrying operation, was also used for un-permitted disposal of commercial, residential and mixed industrial wastes during the mid-1970's. In April of 1981, Diggs illegally dumped contaminated waste sludge containing elevated concentrations of chromium, lead, and cadmium on both the Diggs and the CC&SC properties. |

History of Contamination and Response Actions

On September 26, 1956, CC&CS purchased an undivided one-half interest in a 191 acre parcel of land located on Limestone Road. On September 19, 1973, CC&SC purchased the remaining one-half interest of the parcel. CC&SC indicated that the property was purchased with the intent of using a preexisting limestone quarry on the property. Liniestone had been quarried in areas to the north and east of the Site; however the planned quarry was never developed by CC&SC. In the mid-1970's, CC&SC began allowing various contractors to dump

and more level clean fill (housing demolition material) on the property to provide a larger garbage, drums. working surface. However, bricks, mortar, stone, concrete, wood, domestic

mattresses, glass, furniture, tires, clothing, glass industrial waste, wooden spools, and pallets have all reportedly been dumped into a ravine on the property.

Joesph Diggs was a licensed waste hauler and he operated Diggs Sanitation Inc. from his adjacent property on Limestone Road. Diggs used the property for un-perrnitted filling and grading operations through the mid-1980s.

In April of 1981, Diggs illegally dumped contaminated waste sludge containing chromium, lead, and cadmium from Fairchild Republic Company (now Fairchild Corp.) of Hagerstown, Maryland. It was estimated that 99 tons of that sludge was disposed of on the CC&SC property and 11 tons on the Diggs property.

The Cuniberland City Dump is located adjacent to and in between the Diggs and the CC&SC parcels] but is not considered part of the Superfund Site and did not receive any of the illegally dumped contaminated sludge (See Figure 2). The Cumberland City Dump fiinctioned as a municipal landfill from 1932 to 1968. Fly ash from coal burning, miscellaneous solid metal wastes, tires, and several crushed, and rusted drums were noted along the banks of the inactive landfill during tlie Site investigation. The amounts of household wastes that may have been disposed in the landfill are unknovm.

I . , , •

The United States Environmental Protection Agency (EPA) issued an Operable Unit One Record of Decision (OUl ROD) on September 30, 1986 to address the immediate threats posed by theexposed waste at the Site. The OUl ROD required capping of the contaminated soils and waste material,on both properties with a low-permeability clay cap and fencing of the capped areas. The OUljiROD also required continued environmental monitoring and the preparation of an Operable Unit Two (0U2) Remedial Investigation and Feasibility Study (RI/FS) to evaluate the local groundwater system. On February 28, 1990, EPA the potentially responsible parties (PRPs) entered into a Partial Consent Decree wherein the PRPs agreed to conduct the work described in the p u i ROD. Construction of the fences and low permeability caps for landfilled areas on both the Diggs and CC&SC properties began in June 1994 and was completed in November 1994! Satisfactory completion of OUl construction activities is documented in the Remedial Action]Report dated September 23, 1996.

1 . . Early findings of the 0U2 RI/FS indicated that six local residential wells contained

elevated levels of metals, including lead, manganese, and cadmium. To address this immediate threat to human health, the PRPs entered into a Removal Administrative Order on Consent (AOC) in April of 1994 wherein the PRPs agreed to provide potable water to the six residences with elevated levels of contaminants in their private wells. In addition, the AOC required the PRPs to conduct potable water to

regular monitoring of an additional 13 nearby residential wells and to provide |any residence found to be contaminated. In accordance with the AOC, bottled

water was provided to residents until a more permanent source of clean water could be installed and the identified residential wells were routinely monitored.

EPA issued the 0U2' ROD on June 28, 1996. The selecteid remedy required the installation of a [waterline and ancillary equipment (a pumping station and fire hydrants) to service the nineteen residents in the vicinity of the Site. In addition, the 0U2 ROD required that institutional controls be implemented to prevent the use of contaminated groundwater for potable use and to prevent the fiature use of the disposal areas in such a way as to potentially expose the fill material.

Shortly after EPA issued the 0U2 ROD, Allegany County officials informed EPA and the Limestone Road PRPs of its long-term plans for providing public waterlines to the citizens in a large section of Cumberland, Maryland. All the parties determined that it would be in the public interest to combine the waterline project mandated by the 0U2 ROD with the County's larger scale project. Accordingly, the PRPs and Allegany County entered into a third-party agreement whereby the remedial design and remedial action work and costs were split between these parties. EPA and Maryland Department of the Environment (MDE) were not parties to this agreement and were not privy to its terms; however, EPA and MDE did not object to the work

proceeding under such an arrangement with limited EPA and MDE oversight; Pursuant to the third party agreement, Allegany County installed the waterline which services the 19 residences mandated by the 0U2 ROD.

Initial Response

In June 1981, following an initial investigation by the Maryland Department of Health and Mental-Hygiene, Diggs Sanitation, Inc. and CC&SC were ordered by the State to clean up their respective properties. The Orders were challenged by Diggs and CC&SC and reversed in a State court action. Subsequently, new Orders were issued to both parties. This action was stayed when EPA became the lead agency for the Site.

In March 1982, EPA conducted a preliminary assessment of the Site which resulted in the proposal for placement of the Site on the Superfimd National Priorities September of 1983, EPA included the Site on the NPL.

Basis for Taking Action

.ist (NPL). In

The risk characterization presented in the Record of Decisi6rf'(RC)D) found that the chemicals present in soils, sediment and groundwater at the Limestone Road Site presentee! a direct contact threat to the public health and environment. Specifically, the OUl ROD stated, "The chemicals

or waters could groundwater, the

exist in amounts above background that, if ingested from the soil, sediment, cause harm to human ingestors and perhaps to other animals (EPA 1986)." For Site did not pose an unacceptable carcinogenic risk. However, non-carcinogenic contaminants present in the groundwater were considered unacceptable.

The following contaminants, hazardous substances' and inorganics were detected in surface and subsurface soils, groundwater and sediment at the Site. The primary COCs for each media are highlighted in yellow.

In order to protect human health and the environment, the ROD ordered that specific remedial actions be implemented at the Site to address the direct contact threat. These remedial actions are discussed below.

IV. Remedial Actions

Remedy Selection

Remedial Action Objectives

The major objectives of the OUl remedy were to cap the areas where contarhinated materials were disposed on the Diggs property-and the CC&SC property to prevent direct contact and to eliminate ithe pathway for contaminant migration to the groundwater, surface water and sediment in the vicinity of the Site. The major objectives of the 0U2 remedy were to provide safe drinking water to the area residents and eliminate their reliance on groundwater for a drinking water supply. The institutional controls were required to prevent fiiture use of the landfilled areas so that the integrity of the caps would not be compromised and the contaminated groundwater would not be used for a drinking water supply.

OUl Remedy

On September 29, 1986, EPA issued a Record of Decision (ROD) for Operable Unit One (OUl) of the Site. The interim remedy selected required the following components:

Capping the contaminated area of the properties with a low-permeability clay • Fencing both properties • Surface water, sediment and groundwater monitoring • Preparation of an 0U2 Remedial Invesdgation and Feasibility Study (R!l/FS) to evaluate

the local ground water system

OU2 Remedy

On June 28, 1996, a ROD for 0U2 was issued which required:

• Installation of a waterline and ancillary equipment (a pumping station aind fire hydrants) to service the residents in the vicinity of the Site j

• Implementation of deed restrictions on the previously capped areas of the Site to prevent use of such areas in a manner that would cause disturbance of the caps

• Implementation of a groundwater management program to prevent installation of drinking water wells in the vicinity of the Site

• Continuation of the long term groundwater, surface water and sediment: currently being implemented pursuant to the OUl ROD and

• Abandonment of existing residential water supply wells.

Remedy Implementation

O U l Remedial Action

In February of 1990, EPA and two PRPs entered into a Partial Consent Decree to perform the work in the OUl ROD. Construction of the fences and low permeability caps for both areas began in June 1994, and was completed in November 1994. Figure 2 shows the properties, the capped areas and the monitoring well locations.

OU2 Remedial Action

Early findings of the 0U2 RI/FS indicated that some local residential wells contained elevated levels of metals. To address this immediate threat, several PRPs entered into an AOC in April 1994 to provide potable water to the affected residents. The 0U2 RI/FS was completed in the Fall of 1995.

Shortly after EPA issued the 0U2 ROD, Allegany County officials informed EPA and the Limestone Road PRPs of its long-term plans for providing public waterlines to the residents

monitoring plans

in a large section of Cumberland, Maryland. All the parties determined that it, would be in the public interest to; combine the waterline project mandated by the 0U2 ROD with the County's larger, scale project. Accordingly, the PRPs and Allegany County entered into a third-party agreement whereby the remedial design and remedial action work and costs were split between these parties. EPA and the Maryland Department of the Environment (MDE) were not parties to this agreement and were not privy to its terms. However, EPA and MDE did not object to the work proceeding] under such an artangement with limited EPA and MDE oversight. Pursuant to the third party ! agreement, Allegany County installed the waterline which services the 19 residences mandated by the 0U2 ROD.

i] •

Institutional Controls

Allegany County created a Groundwater Management Zone which prohibited installation of new groundvvater wells in the vicinity of the Site at the time of the water line construction. However, some] of the residents challenged EPA's decision to permanently abandon their existing wells, citing plans to potentially use their groundwater resource for purposes other than potable water. EPA determined that it did not have the authority to require the abandonment of private residential wells and, on September 27, 2000, issued a Memorandum of Minor Change to the 0U2 ROD which removed this requirement from the 0U2 ROD remedy (Attachment 1.). Allegany County, then offered homeowners the opportunity to connect to the public water supply at the expense of the PRPs and required them to abandon their existing residential wells as a condition to the connection to the public water supply.

In addition, the PRPs filed notices on the deeds to the Diggs and CC&SC properties which provide notice that groundwater use is restricted and those activities \yhich would interfere with or damage the integrity of the caps for each of the two properties are prohibited. The deed notice for the CC&SC property was filed on July 8, 2003, and the deed notice for the Diggs property was filed on June 3, 2005. The deed notices are presented in Attachments 2 and 3:

System Operation/Operation and Maintenance (O&M)

The PRPiS consultant, Conestoga-Rovers & Associates, prepared the Operation and Maintenance Plan (O&M Plan) in June 1994. The plan requires routine Site inspections for the perimeter fences] caps and vegetative cover, drainage swales and monitoring wells. The PRPs are also required' to prepare an annual report of the work performed and a summary of testing results and monitoring data.

The O&M Plan provided figures showing the location of approxirnately 30 monitoring wells used.for the RI/FS. At the time the plan was prepared the PRPs agreed to abandon twenty-five of those wells and monitor the remaining five wells. This Five-Year Review evaluated the groundwater monitoring data from the following five wells: MW-C3, MW-10, CRMW-5A, CRM-8 and CRM-9.' Monitoring well locations are presented in Figiire 3.

During the period of the first Five-Year Review, some of the original monitoring wells had not been properly abandoned due to the steep slopes and terrain of the Site. In addition, the PRPs were waiting to be sure that these locations would not be needed in the fiiture. Once the

first Five-Year monitoring period was finished, it was expected that the; PRPs would abandon the wells; however, the well abandonment has not occurred during this second Five-Year Review cycle. EPA recommends that the abandonment of wells occur during the next Five-Year Review period.

Routine surface water and sediment monitoring began in April 1993, prior to the construction of the'caps, and continued through September 1998, nearly four years after completion of cap construction. Six surface water and sediment locations were selected for analysis for the first Five-Year Review. A total of three surface water and se;diment locations were selected for analysis for this Second Five-Year Review.

V. Progress Since Last Five-Year Review

The Protectiveness Statement of the previous Five-Year Review in 2005 concluded, "The Site remedy is protective of human health and the environment in the short-term because the remedial actions selected in the RODs for OUl and 0U2 were implemented and all immediate threats at the Site have been addressed.

For the Site to be protective in the long-term, inorganics in the groundwater, specifically manganese, must be monitored until the concentrations are below the Risk Based Concentrations level of 800 ug/l identified in the 0U2 ROD. Concentrations have been decreasing over the past ten years and are currently in the range of 1100 ug/l. In addition, the surface water samples indicate that concentrations of cadmium exceed the Region 3 Biological Technical Assistance Group (BTAG) screening value of 0.25 ug/l and stream monitoring data should be updated to determine if cadmium levels are a result of the Site. "

Issues and Recommendations identified in the First Five-year Review included:

Issues:

1. Monitoring wells immediately downgradient of the Diggs property remain above the Risk Based Concentration levels of 800 ug/l for manganese used in the ROD. |

2. Surface water samples from the streams where runoff is likely from the Site indicate levels of cadmium which exceed the BTAG screening values.

-^ Recommendations:

1. The groundwater monitoring should continue to determine if the concentrations of manganese continue to decrease in the fiiture. i

2. The stream monitoring data should be updated.

During this Second Five-Year Review period, the PRP's consultant, Conestoga-Rovers &1 Associates, performed biennial Site inspections of the landfills and security] fencing. These; inspections occurred in the late Fall season of 2008 and June 17, 2010. The inspection report fori

2010 can be found in Attachment A of the Limestone Road Annual 2010 O&M and Interim Monitoring Report, which is presented in Appendix 1. The 2010 biennial Site inspection noted that some Site signs were either missing or damaged; vegetation along reaches of the perimeter fencing was too overgrown to perform inspections of fencing integrity or to note animal burrows; and mowing/brush hogging of the Site did not occur in 2010 due to early snow. EPA recommends that damaged or missing signs be replaced; the perimeter fencing be cleared of vegetation; and the Site landfill caps be mowed/brush hogged so that adequate inspections of the landfill cap can:be made. EPA also recornmends that the timetable for mowing and brush hogging be changed from "After the First Killing Frost" to the second week of November. A discussion of the 2010 Site visit and inspection is presented in Section VI of this Five-Year Review. ]

! )

Groundwater monitoring at the five designated well locations was performed in December 2007 and June 2010. Analytical results from these sampling events are presented in Attachment C of the Limestone Road Annual 2010 O&M and Interim Monitoring Report, which is presented in Appendix 1. A discussion of the groundwater analytical results is presented in Section VI of this Five-Year Review.

As part of the Second Five-Year Review, three surface water and sediment samples were collected on behalf of EPA by TechLaw, Inc. on August 27, 2007. The samples were analyzed by the Bonner Alnalytical Testing Company under procedures outlined in the USEPA Contract Laboratory Program. A discussion of the surface water and sediment analytical results is presented in Section VI of this Five-Year Review.

Upon completion of the Five-Year Review Report for the Site, the results of the review and report will be available to the public at the Allegany C ounty Municipal Building, at the offices of http://epa.gove/5vr or www.epa.gov/arweb.

Document Review

US EPA Region III and on the internet at:

This Five-Year Review included the review of a number of relevant documents including the OUl Record of Decision (9/30/86), the Operafion and Maintenance Plan |(1994), the 0U2 Record of Decision (6/28/96), the Preliminary Close-Out Report (9/28/00), the Remedial Action Report (12/19/03), and the First Five-Year Review Report (1/09/06). PRP contractor reports of O&M activities and other documents on file regarding Site cleanup progress were also reviewed

Data Review

Previous Surface Water and Sediment Monitoring

One of the components of the OU 1 ROD was surface water and sediment monitoring and the 0U2 ROD required continuation of the monitoring program. Routine surface water and sediment monitoring began in 1993, prior to capping the contaminated area on the Diggs and CC&SC properties. Sampling continued through 1998, which was four years after the caps were constructed. The primary contaminants of concern were cadmium, chromium and lead based on the sampling and history of the contaminated sludge disposed at the Site.

In the O&M Plan prepared in March 1994 and modified by letter dated March 1996 from the PRP to EPA, the surface water and sediment monitoring was to be conducted quarterly for three years from completion of the Site caps, after which the program was to be re-evaluated. In the 1997 Annual Report, the PRPs proposed that they be allowed to discontinue the surface water and sediment sampling because they concluded that the Site caps were effective in preventing degradation of the quality of the surface water and sediment and those conditions had improved since the caps were completed.

The PRPs continued to sample for another year awaiting EPA's response to the proposed modification. When the 1998 Annual Report was submitted, the PRPs again requested that they be allowed to discontinue the surface water and sediment sampling and indicated that the sampling would be discontinued unless EPA notified them that their proposed modification was not acceptable. EPA did not respond and the surface water and sediment sampling was

11

discontinued. Consequently, the First Five-Year Review used the 1998 data as the basis for the evaluation of the iprotectiveness of the remedy.

I

Even though the RODs for OUl and 0U2 of the Site did not set any cleanup standards that must be achieved, the 0U2 ROD did include a table of the aquatic screening values used by the Biological Tjechnical Assistance Group (BTAG) for organic compounds. Based on the .analytical results] from 1998, surface water samples from the streams where runoff is likely from the Site indicated levels of cadmium that exceeded the BTAG screening value of 0.25 ug/L.

Current Surface Water Monitoring

For this Five-Year Review, surface water samples were collected at three sampling 'locations in June 2007. Two surface water samples were collected from the unnamed tributary ;that runs along the northwest portion of the Site and one surface water background sample was I collected in Evitts Creek above the confiuence of the unnamed tributary and Evitts Creek ^samples (See Figure 4). Analytical results from this sampling event indicate that levels of [dissolved cadmium had dropped below the BTAG screening value of 0.25 ug/L. Some Total imetals concentrations including cadmium were above BTAG screening criteria. However, all of the targeted dissolved metals were below BTAG screening criteria, EPA Ambient Water Quality Criteria (AWQC) and Maximum Contaminant Levels (MCLs) for drinking water'. Analytical results for Disso^ respectively.

ved metals and Total metals in surface water are presented in Tables 2 and 3,

[ It should! be noted that concentrations of calcium in surface water that exceeded BTAG screening criteria are likely ubiquitous to the environment as limestone is present in the reaches of these streams. 1

Current Sediment Monitoring'

Three sediment samples were collected for this Five-Year Review. Sediment samples were collocated with surface water samples (See Figure 3).

It should be noted that exceedences of screening levels are not, by themselves, an indication of a failure to achieve protectiveness. Screening levels are developed to indicate the potential for unacceptable conditions and the need for additional study. Consequently, EPA in consultation with BTAG, conducted a Site inspection of the unnamed stream on May 4, 2009, to evaluate the status of aquatic life in the streams. Based on the inspection, BTAG concluded that, although cadmium and lead contaminant levels exceed the freshwater sediment screening criteria, the stream supports macroinvertibrates that are indicative of moderately clean water. These invertebrates included crayfish and worms, which were observed in leaf debris samples

collected form the stream. Accordingly, the presence of cadmium and lead at concentrations at or near the BTAG screening criteria within the stream does not appear to interfere with aquatic life in the stream and by inference, the remedy appears to be protective of the environment.

Groundwater (Quality Monitoring i

Groundwater monitoring began with the monitoring well installation during the RI/FS in 1994 which became the basis for the 0U2 ROD in June of 1996. Five of the monitoring wells

II °

were sampled quarterly from June 1994, through December 1998, and semi-annually from March 1999, through December 2002. These wells included upgradient wells CRMW-8 and .CRMW-9; downgradient wells CRMW-5A and MW-C3; and MW-10, which is located in the center of the landfill^. Monitoring well locations for this sampling event are presented in Figure

Annual sampling was approved by EPA in January 2003. The annual sampling events ;for the first Five-Year Review were conducted in April 2003, December 2004, and December '2005.^ After thejfirst Five-Year Review, EPA approved biennial sampling events for the same five monitoring iwells. The biennial sampling events for the second Five-Year Review were conducted in December 2007, and June 2010. Groundwater flow directions are presented in Figure 6. | ; , . • v

The COCs identified for groundwater in the Site Risk Assessment included the following metals: cadmium, chromium, lead, manganese and nickel.. The December 2007 analytical iresults from wells located downgradient of the contaminated area reveal that only manganese :was above the current Risk Based Concentration (RBC) level of 880 ug/l at MW-C3 (880 J/1030 ug/L) See Table 5. In 2010, manganese concentrations had dropped below the current RBC of 880 ug/L and the former RBC of 800 ug/L at both dovmgradient monitoring wells (See Table 6). Based on these concentrations, the risks associated with residential exposure to manganese in groundwater do not exceed EPA's acceptable risk levels if groimdwater at these wells was used for drinking water.

Currently, MW-10 is the only well with manganese concentrations that remain above the current residential RBC of 880 ug/L (See Table 6 and Figure 7C). However, this well is located in the center of the landfill where residential land use and groundwater use have been restricted by ICs. It should be noted that concentrations of manganese in groundwater haye fluctuated over the past ten years, but have generally decreased from the highest levels of 2800 to 3300 ug/l in the 1990s to 1,370 ug/L in 2007 and 914 ug/L in 2010.| :See Figures 7A to 7E for a time trend analysisof Site groundwater COC concentrations. j '

As seen in Figure 7D and Table 6, a long-term trend (since 1994) of very low detections of lead in MW-C3 suddenly changed with the June 20,1'0 sampling event. At that time, lead concentrations jumped from near zero to 37.8 ug/L (45.2 ug/L in duplicate). This is most likely an anomalous result. It should be noted that concentrations of lead in groundwater have occasionally spiked above the lead MCL of 15 ug/L inlother Site wells: upgradient well MW-1/CRMW-8 in June 1996; and downgradient well CRMW-5A in June 1998 (See Figure 7D). The high lead result at MW-C3 in 2010 should be verified as anomalous during sampling event. i

the next planned

Concentrations of all other COCs were below: Safe Drinking Water Act Maximum Contaminant Levels (MCLs) and residential RBCs at both upgradient (CRMW-8 and -9) and both dovmgradient (CRMW-C3 and -5A) monitoring wells.

Site Inspection {'

i I On October 18, 2010, EPA and PRP representatives conducted a Site inspection as part

of this Five-Year Review to assess the protectiveness of the remedy including the presence of fencing to restrict access, the integrity of the caps and monitoring well locations!

• ^ ' i • I The inspection was conducted by the former EPA Remedial Project Manager, Roy

Schrock and the current EPA Remedial Project Manager, Robert Wallace. The PRP's

15

representatives who are responsible for implementing O&M for the Site, Stan Levanger, Goodyear Global Environmental Engineering, and John Garges, Conestoga Rovers and Associates were blso in attendance. Based on the inspection, as well as the reports prepared by the PRPs contractor, the security at the Site was good with no signs of vandalism and the landfill caps were intact. Monitoring wells were identified and appeared to be in good condition. Analytical results used in this Second Five-Year Review were discussed during the inspection. In addition, clearing of brush around the perimeter fencing and installation of new signs to replace aging or missing signs was discussed. It was noted that the landfill covers were last mowed in the Fa 1 of 2008 as the first killing fronts had not yet occurred in 2010.

The institutional controls were implemented by filing notices on the deeds to the properties which iprovide notice that groundwater use is restricted and that activities which would interfere with or [damage the integrity of the caps for each of the two properties are prohibited. The deed notice for the CC&SC property was filed on July 8, 2003 and the deed notice for the Diggs property \yas filed on June 3, 2005 (See Attachments 2 and 3).

Interviews

EPA conducted one personal interview with the Allegany County Health Department Director of Public Health, Mr. Brian Dicken. He was not aware of any public concerns or recent inquiries about the status of the Site and there have not been any complaints about dumping recently. EPA informed Mr. Dicken "about the status of the Five-Year Review, the stream sampling event and the subsequent inspection of the unnamed stream and Evitts Creek by a BTAG expert. Mr. Dicken was also informed about results from the groundwater monitoring events indicating decreasing trends in concentrations of manganese and other metals. When asked if he knev^ if the Limestone Road residents, who were placed on city water as part of the Site remedy, had been keeping up with their water bills or had any concerns about their water system, Mr. Dicken indicated that the Allegany Department of Public Works would have that information. He then provided EPA with a phone number and contact name.

EPA later conducted a telephone interview with Mr. Jim Webber of the Allegany County Department of Public Works. Mr. Webber had not heard of any concerns from Limestone Road residents about their public water system. When asked if the Limestone Road residents had been keeping up with their water bills, Mr. Webber instructed the accounting department to run a database search. [The results of the search indicated that two of the residents had either requested that their water be turned off or had had their water cut off for non-payment. As no phone numbers were available for the Limestone Road residents who have terminated their access to the public water drinking water.

supply, it is unclear if these residents are using area groundwater for their

16

VII. Technical Assessment

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

Yes, with the exception of the groundwater management program. EPA has determined the two residences are potentially using \yells that should have been abandoned as part of the waterline installation. However, it shouW be noted that residential well sarripling performed during the RI/FS indicated that the maximum concentrations of contaminants idetected at these two residences (identified as sample locations DW-OOl and DW-002) were below both MCLs and action levels (See Attachment 4). i

Question B: Are the exposure assumptions, toxicity data, cleanup levels, and RAOs used at the time of the remedy still valid? !

Standards and TBCs

Have standards identified in the ROD been revised, and would such revisions call into question the protectiveness of the remedy?

The protectiveness of the remedy is not called into question even though some changes to MCLs, RBCs and BTAG screening values have occurred. The RBC for manganese changed from 800 ug/L to 880 ug/L during the period of this FivcrYear Review. Other]screening values for COCs at this Site (cadmium, chromium, lead and nickel) have not changed since the ROD.

Do newly promulgated standards call into question the protectiveness of the remedy?

No.

Have TBCs changed so as to call into question the protectiveness of the remedy?^

No

Exposure ;

Have land uses on or near the site changed, and would this affect the protectiveness of the remedy?

No.

Have routes of exposure or receptors been newly identified or changed in a way that could affect the protectiveness of the', remedy? Are there newly identified contaminants or contaminant sources that could affect the protectiveness of the remedy?

Yes. The installation of the public water supply was supposed to eliminate the potential for human exposure by ingestion of the groundwater and there have been no

17

newly identified

contaminants at the Site. However, it appears that one of the residents has had their public water supply cut off for non-payment and another has requested that their water be turned off. EPA recommends that| these residents be contacted to determine if they are now using groundwater for their drinking water. If so, EPA recommends that the residential wells be tested for Site-related contaminants.

Are there unanticipated toxic byproducts of the remedy not previously addressed by the decision documents?

No.

Have physical site conditions or the understanding of these conditions changed in a way that could affect the protectiveness of the remedy?

No.

Toxicity and Other Contaminant Characteristics

I • Have toxicity factors changed in a way that could affect the protectiveness of the remedy?

No.

Have other contaminant characteristics changed in a way that could affect the protectiveness of the remedy?

The contaminant characteristics have not changed in a way that would affect the protectiveness ofj the remedy. Even though EPA has made some changes to the toxicity factors, the toxicity factors for the COCs at this Site (cadmium, chromium, lead, nickel and manganese) have not changed since the ROD.

Changes in Risk Assessment Methods !

Have standardized risk assessrnent methodologies changed in a way that could affect the protectiveness of the remedy? \

i

The protectiveness of the remedy is not affected even though new risk assessment guidance has been issued since 1996. iThe most notable changes are in the field of dermal risk assessment, but the recommendation to continue monitoring manganese levels in groundwater will allow for re-evaluation if needed. .

18

Expected Progress Toward Meeting RAOs

Is the remedy progressing as expected?

Yes. Concentrations for cadmium, chromium, and nickel have remained below the MCL with some decreases in concentration after the caps were constructed. As noted in Section VI,_ concentrafions of lead spiked above MCL at downgradient well MW-C3 in June 2010. This result is likely anomalous, but will be verified during the next planned round of sampling. Concentrations of manganese have decreased since the caps were placed materials, decrease.

on the landfill; Based on the current trend, concentrations of manganese are expected to continue to

Question C: Has any other information come to light that could call into question the protectiveness of the remedy?

No.

Technical Assessment Summary

According to the data reviewed, the Site inspection, and interviews, the remedy is fimctioning as intended by the RODs with the exception of the groundwater management program. Concentrations of manganese have decreased over the past 10 years such that concentrations in both dovmgradient monitoring wells are now below the associated RBC. Manganese remains above the RBC only at MW-10, which is located in the center of the landfill. Dissolved lead levels spiked above MCL during the last round of sampling in June 2010. As this result is likely anomalous, it will be verified during the next planned round of sampling.

In addition, although surface water and sediment samples collected in 2007 indicated that concentrations of cadmium and lead exceeded the BTAG screening values, an inspection of the

unnamed stream by a BTAG specialist concluded that the stream supports macroinvertibrates that are indicative of moderately clean water. Thus, the remedy appears to be protective of the. environment.

The installation of the public water supply was supposed to eliminate human exposure by ingestion of the groundwater and there have been no contaminants at the Site. However, it appears that one of the residents has had their public water supply cut off for non-payrnent and another has requested that their water be turned off It should be noted that residential well sampling performed during the RI/FS indicated that the maximum concentrations of contaminants detected at these two residences (identified as sample locations DW-OOl and DW-014) were below both MCLs and action levels (See Attachment 4). EPA recommends that these residents be contacted to determine if they are now using well water. If so, EPA recommends that the residential wells be tested for Site-related contaminants.

VIII. Issues

Issues

1. As part of the Limestone Road Remedy, a public water system was installed for residents that were located downgradient of the Site. Two of the residents have had their public water supply either turned off or requested that the water be turned off. .2. Site inspections revealed that several signs were missing or damaged alongi the perimeter fencing; Some areas of perimeter fencing were too overgrown to observe fencing and potential burrow holes; and the Site has not been mowed and brush hogged due to early season snow.

X Protectiveness Statement

The Site remedy is protective of human health and the environment 'in the short-term because the remedial actions selected in the RODs for OUl and 0U2 were implemented and all immediate threats at the Site have been addressed. However, this Five Year Review found that two of the nineteen residences that were connected to the public water supply have had their public water turned off. Nonetheless, it should be noted that the imaximum concentrations of contaminants detected at these two residences (identified as sample locations DW-OOl and DW-014 in the RI/FS) were both below MCLs in sample analyses performed during the RI/FS. Moreover, current data (2010) collected from monitoring wells located downgradient of the landfill and upgradient of the homes indicate that the manganese concentrations have dropped below risk based concentrations, sampling event.

Long-term protectiveness will 'be verified during the next

In addition, although concentrations of cadmium and lead in sediment were just above BTAG screening levels in recent sampling, an inspection of the unnamed stream by a BTAG specialist concluded that the stream supports macroinvertibrates that are indicative of moderately clean water. Thus, the remedy the remedy appears to be protective of the environment.

XI. Next Review

The next Five Year Review for the Limestone Road Site is five years from the date of this review.

Insignificant Change to the 0U2 Selected Remedy for the Limestone RoAd Superfiind Site^Cumberland, Maryland

Lesley Btrmker, RPM . / / . c .

Limestone Road Site File

SEP

SDMS DocID 2010024

2 7 2000

In conformance with the second operable unit Record of Decision ("0U2 ROD''), issued September 28, 1996, the 19 residences impacted by the Limestone Road Superfund Site ("Site") have been connected to a public waterline which now provides a permanent source of potable water. Several of the residents have challenged EPA's intent to permanently destroy their existing wells, citing plans to utilize the unmetered water source for geothermaljheating/cooling, car washing, lawn irrigation or other non-potable purposes. This memorandum affirms EPA's recognition that all risk reduction goals established at the Site have been achieved without compelling private homeowners to abandon their existing wells. The 0U2 ROD documents that there are no potential health risks posed by the contaminated groimd water wheii used to water lawns or wash cars. Further, there are no applicable or relevant and appropriate jregulations which grant EPA the legal authority to force the homeowoiers to abandon their priva,tely.-pwned wells. Accordingly, EPA is making a minor change to the selected remedy by acknowledging that private well abandonment is a voluntary action.

The minor change described above will not have a significant impact on the scope, performance or cost of the remedy. EPA continues to recommend that homeowners who do not intend to utilize their private well for non-potable purposes properly abandon their residential well. In the event that a home well is abandoned, such abandonment should be accomplished in accordance with the Code of Maryland Regulations 26.04.04. j

1.0 INTRODUCTION

This report presents the results of the groundwater sampling event completed in June 2010 at the Limestone Road Site (Site) in Cumberland, Maryland.

A partial Consent Decree for the Site was executed by the United States Environmental Protection Agency (USEPA), the State of Maryland, Cumberland Cement and Supply Company (CC&SC), and Fairchild Industries, Inc. The partial Consent Decree (Civil Action jNo. R-88-2933), which became effective in December 1989, specified the requirements to be fulfilled as an Interim Remedy for the Site.

The requirements of the Interim Remedy (hereinafter referred to as Interim Remedial Action I [IRA]) included data collection; remedial activities consisting of grading,

capping, and fencing; and monitoring of groundwater, surface water, and sediment. ii

The data collection activities required under the IRA were completed during the period between April 1990 and June 1993 and the results were reported in the "Final Supplemental Remedial Investigation Report" dated March 1, 1995. The Operation and Mainteriance (O&M) Plan for the IRA implemented at the Site is contained in the document "Operation and Maintenance Plan" dated March 11,1994.

An Interim Monitoring Program (IMP) was included in the O&M Plan to monitor the

effectiveness of the IRA. The components of the IMP were: surface water, sediment, and

groundwater quality monitoring, and hydraulic monitoring. The IMP was implemented

at the commencement of the cap construction activities (June 1994). Quarterly IMP

activities were completed between June 1994 and December 1998, and semi-annually

from March 1999 through December 2000. The IMP is currently being conducted on an

annual basis. I

The purpose of this report is to present a summary of the IMP and O&M activities performed at the Site during the calendar year 2010. This report discusses the groundwater monitoring data collected during the latest sampling event and assesses the Site [conditions in terms of the effectiveness of the IRA to facilitate delisting of the Site by the USEPA. This report is organized in the following sections as follow^s:

1 I

i) Section 1 presents a brief history of the project and description of the O&M and inonitoring activities;

ii) Section 2 presents a cornprehensive summary of the O&M activities performed during this reporting period; .

004550 (49) CONESTOGA-ROVERS & ASSOCIATES

iii) Section 3 presents the groundwater monitoring data collected during 2010;

iv) Section 4 presents a discussion of the groundwater monitoring data; and

v) Section 5 presents the conclusions drawn from the information gathered during

the O&M and monitoring activities to date.

004550 (49) CONESTOGA-ROVERS & ASSOCIATES

2.0 OPERATION AND MAINTENANCE ACTIVITIES

O&M activities performed during this reporting period were conducted on June 17, 2010. Inspection of the two landfill caps (northwest and southeast) and an inspection of the Site security features, signage, and drainage w^ere completed. The O&M activities were performed by or under the direct supervision of the designated Site Custodian, Conestoga Rovers & Associates (CRA).

2.1 SITE INSPECTIONS AND CORRECTIVE ACTIONS

The landfill cap inspections were performed on June 17, 2010. Observations made

during the inspection process were logged on inspection log sheets and are presented as

Attachment A.

A brief summary of the inspection observations and corrective actions implemented (if

any) are; presented in the following subsections.

2.1.1 I SECURITY I

The Site security features include cap perimeter fences, fence gates and locks, and signs. In sumrnary, inspection of the security features was hampered by the presence of dense underbrush throughout the Site. Some slight damage to the security features, specifically signage, was noted during the inspection. However, the integrity of the Site security; features appears to be generally good. Some attention to reposting of signage along the landfill should be made, following removal of the dense underbrush. The security features and their relative condition are described below.

Northwest Cap

The perimeter fence could not be inspected along the south side and portions of the east

and west sides due to excessive tiee/brush growth. No problems were observed on the

perimeter fence gates and locks. Signs were not visible on the north, west, or south sides

of the fence due to the dense vegetation growth. The signs posted on the east side of the

Site, were observed to be damaged and will require replacement.

004550(49) ; 3 CONESTOGA-ROVERS & ASSOCIATES

Southeast Cap

No damage was directly observed to the perimeter fence during this reporting period.

However, the perimeter fence gates and locks could not be inspected due to excessive

vegetation growth. No signs were directiy observed along the fence i line due to the

dense undergrowth.

2.1.2 SITE I

• • • !

The Site features include final and vegetative covers, drainage swales, and monitoring

wells. An attempt to examine each of these features was made during the Site

inspection. As noted on the Inspection Log Sheets in Attachment A, dense growth of

trees and brush were observed on both caps and along the fence lines. Drainage swales,

where visible were generally found in good condition, with no signs of erosion. Site

monitoring wells were found to be in acceptable condition.

u • • ' • i

2.2 ROUTINE MAINTENANCE

The routine maintenance activities for the IRA consist primarily of the maintenance of the cap vegetative covers through fertilization, reseeding, cutting, and application of herbicides as "necessary. The O&M Plan requires cutting of the Site vegetation after the first kiUing frost once every three years to maintain a diversity of flora and fauna.

The next routine maintenance event should be conducted as soon as possible or after the

first killing frost in ihe fall of 2010. i

004550(49) 4 CONESTOGA-ROVERS & ASSOCIATES

3.0 SITE MONITORING I .

On June 16 and 17, 2010, hydraulic monitoring and groundwater sampling were completed at five monitoring well locations (CRMW-5A, CRMW-8, CRMW-9, MW-C3, and MW-10). The following subsections present summaries of the groundwater analytical data collected during the IMP. The analytical database for the five monitoring wells, including the results for the June .2010 sampling event, is provided as Attachment B.

3.1 j; GROUNDWATER

The groundwater monitoring network for the IMP consists of the two background

monitoring wells (CRMW-8 and CRMW-9, the replacement wells for MW-1 and MW-2,

respectively) which are hydraulically upgradient from the Cumberland Cement and

Supply Company (CC&SC) property, and three monitoring wells (MW-10, MW-C3, and j

CRMW-5A) which are hydraulically downgradient from the CC&SC and Diggs properties. The locations of the monitoring wells included in the IMP are shown on Figure 1.

Each' groundwater sample was analyzed for dissolved Target Analyte List (TAL)

metals and total cyanide.

Water Quality Data

The concentrations of the five metals (cadniium, chromium, lead, manganese, and nickel) which were detected during the Supplemental Remedial Investigation (SRI) at concentrations which exceeded Maximum Contaminant Levels (MCLs) or other USEPA action levels have been graphed for the five IMP groundwater monitoring well locations

to illustrate changes over time. These graphs are presented in Attachment B. ! i

Hvdraulic Monitoring Data

In addition to the water quality monitoring. Site-wide hydraulic monitoring was

performed from June 1994 through September 1996. Begirming in December 1996, the I

hydraulic n\onitoring was limited to that required by the IMP; namely, the two background monitoring wells (CRMW-8 and CRMW-9) and three downgradient

monitoring wells (MW-10, MW-C3, and CRMW-5A). A tabulation of the groundwater

elevations measured during the IMP, as well as selected groundwater elevations

measured during the RI and SRI, are presented in Table 1. The groundwater elevations

004550(49) 5 CONESTOGA-ROVERS & ASSOCIATES

for the five monitoring wells which comprise the IMP groundwater quality monitoring

wells have been contoured and are presented on Figure 2. : •

4.0 DISCUSSION OF RESULTS

4.1 INTERIM MONITORING PROGRAM

4.1.1 I GROUNDWATER QUALITY

The groundwater analytical graphs for cadmium, chromium, lead, manganese, and

nickel are presented in Attachment B.

i) Cadmium continues to be non-detect in the IMP monitoring wells since April

2003. '

ii) Chromium has not been detected above 1 |ag/L in any IMP monitoring well since March 2002. Chromium was not detected in any well in June 2010.

iii) Except in December 1998, the concentrations of manganese in the background rhonitoring wells and downgradient monitoring well MW-C3 have consistentiy declined over the course of the IMP. An overall decreasing trend is also apparent ih CRMW-5A. The June 2010 concentration of dissolved manganese (914 ug/L) in MW-10 (located within the capped area) is at an historic low, slightiy below

• the historic range of concentiations of manganese detected during the IMP..

iv) Lead was detected at a concentration of 37.8 ug/L in MW-C3 and its duplicate sample (45.2 ug/L) in June 2010.

v) Nickel continues to be non-detect in the two background wells, and has not been detected in either of the background monitoring wells since December 2005. The downgradient monitoring weU MW-10, continues to exhibit low level nickel concentrations (less than 5 ug/L). In addition, each of the detected nickel results from the June 2010 event was "B" qualified, indicating the reported result was estimated below the laboratory reporting limit. The concentration of dissolved nickel in downgradient monitoring wells MW-C3 and CRMW-5A\ appear consistent with historical averages.

vi) The concentrations of cadmium, chromium, and nickel in the IMP monitoring

•yvells in 2010 were all lower than the MCLs or action levels for these compounds.

vii) Cyanide was detected in the groundwater samples collected from CRMW-8 (117

xig/L) and MW-C3 (27.6 ug/L), above the laboratory detection limit.

4.1.2 GROUNDWATER ELEVATIONS

As shown on Table 1, the groundwater elevations in the five groundwater monitoring

wells included in the IMP have not varied significantiy over the monitoring period.

004550 (49) CONESTOGA-ROVERS & ASSOCIATES

5.0 CONCLUSIONS AND RECOMMENDATIONS V

5.1 MONITORING i

5.1.1. ANNUAL RESULT i

The recent June 2010 data continues to demotestrate that groundwater quality at all the

monitored locations is generally stable or improving and that the only monitored

parameters which are occasionally present at concentrations which exceed the action

criteria is lead and/or manganese in the dov^mgradient monitoring wells. The graphs

showing the concentrations tiends of the Site Indicator Compounds,'(i.e., cadmium,

chromium, lead, manganese, and nickel) in the IMP monitoring wells are presented in

Attachment B. The reviews of the hydraulic monitoring data have demonstrated that

there have been no significant changes in the water level elevations in the monitored

wells over time.

5.2 OPERATION AND MAINTENANCE ACTIVITIES

The Site inspections are currently performed annually. The vegetative cover of the caps

are now well established; therefore, erosion of the caps is not occurring under normal

circumstances. Since the conditions of the Site caps and swales are stable, it is proposed

that the frequency of Site inspections continue on an annual basis.

5.2.2 WELL ABANDONMENT

Abandonment of monitoring wells not included in the IMP was proposed in

November 1996. The abandonment was approved by USEPA in a letter dated April 4,

2001.
