C) <br /> s - <br /> if the groundwater in the aquifer is contaminated then the soil <br /> in the aquifer will be contaminated from the contaminated water. <br /> Based on prior work, the calculated gradient varies but is <br /> generally south easterly. <br /> The properties in the area within a 2,000 foot radius surrounding <br /> the subject site are all reported to be on city water. <br /> PROPOSED WORK <br /> The proposed workplan for this quarterly monitoring will require <br /> seven tasks identified below. The workplan can be completed <br /> three weeks after SCSAMS has approved the workplan. <br /> Prior to any work being performed, JPCA will coordinate the work <br /> with SJCEHD with a 48 hour notice. <br /> I <br /> Task 2 <br /> JPCA will measure the groundwater depth in the five monitoring <br /> wells with an electronic probe prior to purging. A site plan is <br /> �1 shown in Figure 2. <br />` ` Task 3 <br /> The five monitoring wells will be purged prior to the collection <br /> of .groundwater samples and the collected purged groundwater will <br /> be put in 55-gallon drums labeled awaiting analysis. <br /> Task 4 <br /> One groundwater sample will be collected from each monitoring <br /> well, after the wells are purged and allowed to recharge. A <br /> clean dedicated bailer will be_ ,used to obtain the samples, then <br /> the samples will be placed 'in four 40-ml VOAs with Teflon septa <br /> and a one liter glass jar, labeled, held in a cooled (4 Degrees <br /> C) ice chest and transported to a State Certified Laboratory, <br /> under Chain of Custody (COC) documentation, for analyses. A <br /> maximum of 5 groundwater samples is anticipated to be collected. <br /> Task 5 <br /> The groundwater samples collected will be analyzed for Total <br /> Petroleum Hydrocarbons as Diesel (TPHD) , Total Petroleum <br /> Hydrocarbons as Gasoline (TPHG) via EPA protocol 8015 Modified, <br /> Benzene, Toluene, Ethylbenzene and Xylene (BTEX) via EPA protocol <br /> 8020 : Oxygenates [DIPS, ETBE, MTBE, TAME, tert-Butanol and 1,2 <br /> - 2 <br />
