STANDARD OPERATING PROCEDURE .CROUNDWATER SAMPLING

. .6ettler-Ryan..lnc.. field personnel adhere lo rhe following procedures for the collection and handling ofgroundwater samples prior to analysis by the analyical laboralory. Prior to sarlple collection, rhe iypeof analysis to be performed is determined. Loss prevention of volatile compounds is controlled andsample preservation for subsequent analysis is maintained.

Prior to sampling, lhe presence or absence of free-phase hydrocarbons is determined using an interfaceprobe. Product thjckness, ifpresent, is measured to the nearest 0.01 foot and is noted in the field notes.ln addition, slatic waler level measurements are collected with the interface probe and are also recordedin the field notes.

'After water levels are collected and prior to sampling, eacb well is purged a minimum of three wellcasing volumes of water using pre-cJeaned pumps (srack, sucrion, Grundfos), or polyvinyl chloridebailers. Temperature, pH and electrical conductivity are measured a minimum of three times during rhepurging. Purging continues until these paramerers stabiljze.

Groundwalet samples are collected using Chevron-designared disposable bailers. The water samples aretransferred from the bailer into appropriate containen. Pre-preserved containers, supplied by analyicalIaboralories, are used when possible. When pre-preserved containers are not available, the liboratory isinstructed lo preserve the sample as appropriate. Duplicate samples are collected for the laboratory rouse in majntaining quality assurance/quality contrcl standards. The samples are labeled to jncludgthejob number, sampJe identification, collection date and rime, analysis, preservation (if any), and the sarnplecolleclor's initials. The water samples are placed in a cooler, maintained at 4oC for rranspon ro ihelabotatory. Once collected in the field, a1l samples are mainrained under chain of custody until deljveredto lhe laboratory

The chain of custody document includes the job number, type of preservarion, if any, analysis requested,sample identificat;on, dale and time collected, and tbe sample collector's name. The chajn of cuitody issigned and dated (incJuding dme of rznsfer) by each person who receives or surrenders the sampies,beginning with rhe field personnel and ending with tbe laboratory personnel.

A laboratgry supplied trip blank accompanies each sampling set. For sampling sets grearer than Z0sarnples, 5% trip blanks are jncluded. The trip blank is analyzed for some or all of the same comDoundsas the groundwaler samples.

As requested by Chevron Producls Company, the purge water andduring sampling activities is transponed by tWV to McKirrrjckMcKittrick. Califomia.
