labeled, DOT-approved, 55-gallon storage drum The submersible pump was decontaminated <br /> between each use by circulating first potable water and then deionized water through the system <br /> After purging each well of three well casing volumes of water, a groundwater sample was <br /> collected from each well using a disposable polyethylene bailer The sample water from each well <br /> was carefully poured from the bailer into three 40 ml glass rials (VOA vials) and two 1 liter <br /> amber glass bottles The sample bottles were labeled, recorded on a chain-of-custody form, and <br />' stored in a chilled ice chest for transportation to American Environmental Network - a State <br /> certified analytical laboratory A travel blank was prepared using distilled water to evaluate <br /> potential sample contamination dunng storage and transport of the samples Transport and <br /> handling of samples were performed under strict chain-of-custody protocol The groundwater <br /> analytical data sheets and chain-of-custody records are contained in Appendix A of this report <br /> The groundwater samples were analyzed for benzene, toluene, ethylbenzene and total <br /> xylenes (BTEX) and purgeable Total Petroleum Hydrocarbons (TPH) using EPA Methods 602 <br /> and 5030, respectively, and extractable TPH using EPA Method 3510 The travel blank was <br /> analyzed for BTEX Results of the recent groundwater chemical analyses are shown on Figure 3 <br /> and in Table 2, along with the histoncal groundwater data <br /> 4.0 DISCUSSION OF GROUNDWATER QUALI'T'Y <br />' Groundwater samples collected from Well MW-2 yielded the highest concentrations <br /> detected at the site Table 2 shows that the compounds detected in the sample collected from <br />' MW-2 included gasoline range TPH (TPH-g = 0 4 mg/L), diesel range TPH <br /> (TPH-d = 009 mg/L), benzene (4 pg/L), toluene (1 pg/L), ethylbenzene (1 µg/L), and total <br /> xylenes (3 pg/L) (see also Figure 3) This was the only sample that yielded detectable BTEX <br />' concentrations <br />' TPH-d was detected in all of the wells sampled, at concentrations ranging from 0.08 mg/L <br /> in MW-4 to 0 2 mg/L in MW-3 and MW-5 BTEX compounds were only detected in the sample <br />' from Well MW-2 (Table 2 and Figure 3) No VOCs were detected in the travel blank <br /> R41820A 121950-2 <br /> athgtr 95 2 <br />
