DOMESTIC WELL SAMPLING AT 10757 COPPEROPOLIS ROAD, STOCKTON, <br /> SAN JOAQUIN COUNTY <br /> As an initial site assessment relating to the underground storage tanks at the former Countryside Market, <br /> staff sampled six domestic water supply wells in close proximity to the Countryside Market location. <br /> Your domestic well was sampled on 24 April 2001, and again on 23 May 2001. On both dates, the <br /> holding tank was purged approximately five minutes until the pump turned on, and then a sample was <br /> collected from a hose bib at the wellhead. A clean brass hose connector and a one-foot piece of <br /> disposable polyethylene tubing were used to transfer the water sample from the hose bib into sample <br /> containers provided by the laboratory. The sample containers were labeled,placed directly into a pre- <br /> cooled ice chest with ice, and submitted to California Laboratory Services (CLS) in Rancho Cordova for <br /> analysis. The 24 April samples were analyzed by EPA Method 8260B for volatile organic compounds, <br /> and the 23 May samples were analyzed by EPA Method 8260B for volatile organic compounds, by EPA <br /> Method 8015M for gasoline, and by EPA Method 200.8 for organic lead. On both sampling dates, the <br /> sample was designated"CSM10757" for 10757 Copperopolis Road domestic well. The trip blank for <br /> 24 April was designated"TCMW-2" and the trip blank for 23 May was designated"CSM10710". <br /> The water sample from your domestic well did not contain any constituents at respective detection <br /> limits. A copy of the CLS laboratory report is attached for your records. If you have well construction <br /> details for your well,we would appreciate a copy of the documents. If you have any questions,please <br /> call me at (916) 255-3115. <br /> Marty Hartzell <br /> Associate Engineering Geologist <br /> Attachments <br /> cc: Ms. Margaret Lagorio, San Joaquin County Environmental Health Division, Stockton <br /> File: Countryside Market, 10848 Copperopolis Road, Stockton <br /> California Environmental Protection Agency <br /> ea Recycled Paper <br /> The energy challenge facing California is real.
