Each water sample collected will be labeled, logged onto a chain- <br /> of-custody form, and p*W in a chilled ice chest. Upon completion of the well <br /> sampling, the well will bi clowd and locked and the sampler will move to the next <br /> sampling point. Sampletwill be analyzed by a state-certified analytical laboratory by <br /> the test methods desaribed.below in Task 1.4. Upon completion of field monitoring <br /> and analytical testing a report of findings will be prepared for submittal to the PHS- <br /> EHD, and the California ate Water Resources Control Board (SWRCB). <br /> Task I.4 - Chemical, Pkat, and Biological Parameters Testing <br /> At least one soil core shoNili be collected from within each of the two on site aquifer <br /> lithofacies(one frau theolirth ekk and one from the south side of the property) for <br /> permeability testing. The tiwo values can then be averaged for identifying the <br /> groundwater flow nttea. <br /> Up to three soil "Avtes ilAd six groundwater samples will be submitted for analysis for <br /> the following: <br /> • TPH-G by EPA r ,8015M <br /> • BTEX by EPA X8;8020/602 <br /> At least one soil sample iM silt groundwater samples will be analyzed in the field or, (" <br /> laboratory (depending appopriate protocols and equipment available to the samplers) <br /> for the following; <br /> • Dissolved oxygen codho either by down-hole meter reading or immediate surface <br /> measurement by the WlWder method. <br /> • Oxygen-reduction poNii" by method AB25880 (filled from the bottom, and <br /> analyzed immadliucly); <br /> • pH by EPA method *.1, or SW-9040, or a direct reading meter. <br /> • Conductivity by EPA".Awhod 120.1 or SW-9050, or a direct reading meter. <br /> • 'Temperature by EPA:'llai hod 170.1 (preferably by down-hole meter reading). <br /> 1• Alkalinity by Alkalinky test frit model AL AP MG-L, method A2320, or EPA <br /> metbod 310.2. <br /> a Nitrate by EPA methi784353.2, or SW-9200, or HACH method 8039, or 8192. <br /> a Sulfate by EPA metNdt333.2, or SW-903619038, or HACH method 8051. <br /> a Ferrous Iron by EPA'inithod 200.7, or SW-6010, A3500, or HACH method <br /> 25140-25. <br /> a Biologic screening Wiisumed psuedomonas genera. <br /> Car Car ProjecrNo. 4090 DRAFT' Page 4 <br />
