Water Level Data, Chevron 5,5, #96465, Stockton, California <br /> Ground Water <br /> Top-of-Casing Depth to Elevation <br /> Elevation Water (ft relative <br /> Well ID (ft above msl) Date (ft) to msl) <br /> MW-1 7.86 2/4/88 26.85 -18,99 <br /> MW-2 7.99 2/3/88 27,17 -19.18 <br /> MW-3 8.49 2/4/88 27.59 -19.10 <br /> MW-4 7.75 2/4/88 26.78 -19.03 <br /> MW-5 7.72 2/4/88 26.61 -18.89 <br /> MW-6 8.16 2/3/88 27.51 -19,41 <br /> MW-7 8.6 2/4/88 28.08 -19.39 <br /> B&C are included as Attachments B, C, and D, respectively, and the results are <br /> presented in Table 3. <br /> Soil samples from the borings were below analytic detection limits for <br /> TFHC, which is consistent with OVA measurements. Ground water samples from <br /> MW-2, MW-3, MW-5 and MW-7 were below detection limits for TFHC and BTX. <br /> Ground water samples from MW-2, MW-3, MW-5 and MW-7 were below detection <br /> r for TFHC and BTX. The ground water samples from MW-1, MW-4 and MW-6 contained <br /> .021 ppm, .0018 ppm and .0014 ppm benzene, respectively. The ground water <br /> samples from MW-1 and MW-4 contained .0019 and .0006 pprn toluene, <br /> respectively, and the sample from MW-6 was below the toluene detection limit, <br /> The ground water sample from MW-1 contained .013 ppm xylenes and the samples i <br /> from MW-4 and MW-6 were below the xylene detection limit. <br /> s <br /> CONCLUSIONS <br /> The analytic results for the soil samples from the borings were below the <br /> p detection limits for TFHC. The ground •water samples analyzed from wells MW-2, <br /> MW-3, MW-5 and MW-7 were below detection for TFHC and BTX. The ground water <br /> samples from MW-1. MW-4 and MW-6 were above California Department of Health <br /> t', <br />
