Prior to the <br /> collection of groundwater samples, a minimum of.three well volumes (casing and sand pack) will <br /> be purged. Temperature, pH, and electric conductivity will be measured and allowed to stabilize. <br /> Water samples will be collected using disposable bailers, one dedicated to each well. <br /> Groundwater samples collected from all monitoring wells will be submitted using chain-of- <br /> custody record to a State-certified laboratory. Groundwater samples, seven total, will be <br /> analyzed for TPHd. Purge water-will be stored in 55-gallon drums approved for hazardous liquid <br /> storage pending laboratory analysis. <br /> Report Preparation <br /> Upon completion of the well installation and development activities, a summary report will be <br /> prepared for submittal to SJCEHD. The report will include a description of all field activities, <br /> laboratory analytical results, and well/boring logs. <br /> All work described in this workplan will be performed under the direction of a California <br /> Registered Professional Engineer. All work will be performed in accordance with ATC's Site <br /> Safety Plan (SSP) and Quality Control/Quality Assurance Plan, both on file with the SJCEHD. <br /> Projected Schedule <br /> I <br /> Once approval of this workplan has been received, ATC will schedule drilling activities. ATC will <br /> notify SJCEHD prior to beginning any field activities. The summary report will be submitted to <br /> SJCEHD approximately four to five weeks after the completion of field activities. <br /> I <br /> w:%2574.05Vepods\wkpwel.dm 5 <br />
