• Stratus personnel (discussed 1n section 4 2 below), the measured product thickness in well MW-1 <br /> has generally decreased Between January and May 2004, a sheen to 0 03 feet of free product <br /> have been observed in well MW-1 Free product was not reported in newly installed wells <br /> MW-10, MW-12, and MW-15 Based on this observation, the lateral extent of free product <br /> thickness for the deeper screened wells appears to be adequately assessed <br /> GRO and BTEX were reported for the samples collected from newly installed wells MW-10, <br /> MW-12, and MW-15 GRO concentrations ranged between 52,000 µg/L. and 110,000 µg/L, and <br /> benzene concentrations ranged between 4,400 µg/L and 13,000 µg/L. for samples collected on <br /> June 22, 2004 MTBE and other fuel additive concentrations were reported below laboratory <br /> detection limits for the samples collected from wells MW-10, MW-12, and MW-15 The lateral <br /> extent of petroleum hydrocarbon impact to groundwater is not fully characterized southeast of <br /> the site <br /> On-site Water Sppply SupplyWell <br /> Petroleum hydrocarbon and fuel additive concentrations have consistently been reported below <br /> laboratory detection limits for the quarterly samples collected from the ARCO water supply well <br /> • <br /> P\Bp-Arco forOR5161001Reports4arm610Qassessme¢t s r[!update doc Page 10 5 MA W5 <br />
