Fremont Street, Stockton <br /> we are allowing multiple repeataole gw sampling events to occur. Agruments for'drilling induced'or'cross- <br /> contamination' in the past has taught us to allow a trend to develop in gw data before jumping to any conclusions. <br /> if I remember correctly, the Shell site had vadose soil contamination at the northern pump island. This added to <br /> the SE gradient and non detect CPTs across Fremont Street to the north places more possiblity in a possible co- <br /> mingled plume than a "not our problem, it came from across the street'conclusion. <br /> I'm still working on it and the EHD will comment on your position. <br /> Until then I strongly recommend you continue your required investigation and remedial action evaluation. <br /> From: Murphy, Mike [mailto:mrmurphy@craworld.com] <br /> Sent: Friday, February 22, 2008 10:07 AM <br /> To: Mike Infurna [EH] <br /> Subject: RE: 2494 E. Fremont Street, Stockton <br /> Mike—any update on your review. Most recent data sure looks like adjacent site plume is primary cause <br /> of plume beneath the Shell site.
