performed during the 1996 groundwater monitoring The analytical and sampling methods <br /> are discussed in Section 2 1 The groundwater elevation and analytical results are discussed In <br /> Section 2 2 Groundwater sampling protocol are described in Appendix A <br /> 2.1 SAMPLING AND ANALYTICAL METHODS <br /> Depth to groundwater was measured in each of the five monitoring wells using an <br /> electronic water level Indicator Groundwater samples were collected from each monitoring <br /> well after purging at least three casing volumes of water from the monitoring well with a <br /> portable submersible pump Temperature, pH, and electrical conductivity (hereafter field <br /> parameters) were measured during purging and noted on a Field Record of Water Sampling <br /> Form, as presented In Appendix B After equilibration, an aliquot of water was collected from <br /> each monitoring well using a disposable polyethylene bailer After collection each sample <br /> was stored in a cooled ice chest and hand delivered to Quanterra Environmental Laboratories <br /> (Quanterra) in West Sacramento, California for analysis Quanterra is a State of California <br /> Department of Toxic Substances Control (DTSC) certified laboratory Quanterra analyzed each <br /> water sample for total petroleum hydrocarbons as diesel (TPH-d) by EPA Method 8015 <br /> modified <br /> 2.2 ANALYTICAL RESULTS <br /> Field parameter and depth to groundwater data are provided in the table below <br /> Electrical <br /> Depth to Water Conductivity Temperature <br />' Well No. (ft bgs) pH (iumhoslcm) (°F) <br /> DMW-1 52 26 743 840 725 <br /> DMW-2 5269 733 905 732 <br /> DMW-3 5288 733 983 722 <br /> DMW-4 5247 715 984 72 1 <br />' DMW-5 5295 709 923 723 <br />' bgs a below ground surface <br /> 1 <br /> R 15AC1044M1SC19610 04 WPD 2 <br /> DAMES & MOORE <br />
