KLEINFELDER <br /> F No sampling spigots were available on the pump heads of the three deep wells, therefore <br /> ' groundwater samples were obtained from the nearest available discharge points at each well. <br /> Well DW-1 is a DSS plant supply well that reportedly pumps almost continuously therefore <br /> purging of this well was not necessary. The groundwater sample from this well was collected <br /> from a water pipe used to fill trucks located approximately 20 feet from the well head. The <br /> groundwater sample from agricultural well DW-3 was collected from a discharge irrigation <br /> standpipe also located approximately 20 feet from the well head. Because of a high rate of <br /> discharge for these two wells the groundwater sample had to be collected in a relatively large <br /> container. A pre-cleaned 5-gallon plastic bucket was used for this purpose. The groundwater <br /> collected from these two wells (DW-1 and DW-3) were then decanted into appropriate sample <br /> containers from the 5-gallon bucket. Approximately 100 gallons of water was purged prior to <br /> collection of a groundwater sample from DW-3. Approximately 30 gallons were purged from <br /> DW-2B prior to collecting groundwater samples directly from a discharge pipe located about 6 <br /> feet from the well head. Groundwater sampling parameters, pH, specific conductivity and <br /> temperature were taken prior to collecting groundwater samples (for details see Appendix Q. <br /> k Purge water from these three deep wells were not contained. <br /> i 4.4 SAMPLE HANDLING <br /> i <br /> After collection, the groundwater samples were labeled, logged on a chain-of-custody form, and <br /> ! immediately stored in an iced cooler. The samples were transported under chain-of-custody <br /> control to Kleinfelder's office and then transported by courier in a sealed container to Sequoia <br /> Analytical (Sequoia) of Sacramento, California for chemical analysis. Sequoia is certified by the <br /> California Department of Health Services (DHS) to perform the requested analyses. The <br /> laboratory data sheets and chain-of-custody records are included in Appendix D. <br /> } <br /> 20-2245-36.E0 1/2011 8279 Page 6 of 10 <br /> �!, Copyright 2001, Kleinfelder, Inc.
