Following well purging, we allowed the wells to recharge before we collected groundwater samples. We collected the groundwater samples with new, well-dedicated polyethylene disposable bailers and poured the collected groundwater into new 40 milliliter (ml) glass vials and 250 ml amber bottles. Following collection, we immediately placed the water samples on ice in a cooler. JJW did not experience any ambient petroleum-like odors above any of the monitor wells. Specific site conditions and sampling parameters can be found in the Well Sample Field Logs included in Appendix A. JJW transported the groundwater samples under chain-of-custody to TEG - Northern California, Inc. (Certification No. 2012) and Kiff Analytical (Certification No. 2236), State of �. California certified analytical laboratories. The groundwater samples were analyzed for the following parameters: ,., Total petroleum hydrocarbons as gasoline (TPH-gasoline) (EPA method 8260B). Total petroleum hydrocarbons as diesel fuel (TPH-diesel) (EPA method 8015mod). The aromatic fuel components benzene, toluene, ethylbenzene, and xylenes (BTEX), 1,2-Dichloroethane (1,2 DCA), and the fuel oxygenate MtBE (EPA method 8260B). Fuel oxygenates DIPE, EtBE, TAME, tert-butanol, methanol, and ethanol �.. (EPA method 8260B) on selected samples. 1,2-Dibromoethane (1,2 DBA) (EPA method 82606) on selected samples. V 3.2 Analytical Laboratory Results Laboratory analyses indicated that the aromatic fuel component benzene was detected above the laboratory reporting limit in two of the eleven groundwater monitor wells sampled ranging from 1.1 }igIL in MWJA to 10 µglL in MW-5. Monitor well MW-5 is screened through the top of the groundwater table, currently at approximately thirty-one feet below ground surface (bgs). Monitor well MWJA is screened between approximately 100 and 110 feet bgs, adjacent to MW-5. The aromatic fuel components toluene, ethylbenzene, and xylenes were detected in groundwater monitor wells MW-2 and/or MW-5. Toluene was detected in MW-5 at 1.0 µg/L. Ethylbenzene was reported in MW-2 at 2.6 µg/L and in MW-5 at 0.86 µg/L. Xylenes were detected in MW-2 at 14 µg& and in MW-5 at 8.6 fig& TPH-gasoline was detected above the laboratory reporting limit in two of the eleven groundwater monitor wells sampled, at values of 430 µg/l_ in MW-2, and 970 µglL in MW-5. TPH-diesel was not detected in any of the monitor wells sampled. Nine of the eleven monitor wells were sampled for 1,2-dichloroethane (1,2 DCA). Four of the nine monitor wells had low concentrations of 1,2 DCA ranging from 0.64 µglL in MW-5 to 3.0 dig/l_ in MW-1. Laboratory analyses indicated that the fuel oxygenate methyl-tertiary-butyl ether (MtBE) was not detected at or above the laboratory reporting limit in any of the eleven monitor wells �. sampled. Groundwater samples from eight of the eleven monitor wells sampled were analyzed for 1,2-dibromoethane (1,2 DBA), and the fuel oxygenates diisopropyl ether (DIPE), ethyl-t-butyl ether (EtBE), tert-amyl methyl ether (TAME), tert-butanol (TBA), methanol, and ethanol. 3 JJW GEOSCIENCES Inc. w
