Free product was observed in onsite wells MW-4 (0. 04 <br /> foot) and MW-3 (0. 60 foot) . Free product was observed in offsite <br /> well MW-6 (0. 87 foot) , located at the Exxon site across Tracy <br /> Boulevard. This free product appears to originate from a source <br /> other than the former Mobil station (as evidenced by the lack of <br /> free product in AMW-4, and its crossgradient position relative to <br /> the site) . <br /> The general ground water direction at the site is estimated to be <br /> toward the north-northwest with a average hydraulic gradient of <br /> 0. 005 foot/foot across the site. <br /> If you have any questions, please feel free to contact me at <br /> (818) 953-2626. <br /> sincere <br /> ly, <br /> Stephen Pao <br /> Field Engineer II <br /> enclosure <br /> cc: Ms. Elizabeth Thayer (w/ enclosure) <br /> RWQCB - Central Valley Region <br /> 3443 Routier Road <br /> Sacramento, CA 95827-3098 <br /> Mr. Peter DeSantis (w/ enclosure) <br /> BP Oil Company <br /> Southcenter Place Building <br /> 16400 Southcenter Parkway, Suite 301 ME <br /> Tukwila, WA 98188 w <br /> Environmental <br /> Awareness <br />
