Well LM037AA at Tracy Army Depot <br /> I don't have access to the latest sample results (3Q02)today, but VOCs <br /> were not detected in 2000 and 2001. I'm guessing that the 2002 results <br /> were ND too. This well is located more than 1,000 feet upgradient of <br /> the portion of the TCE/PCE plume exceeding 5 Ng/L (Tracy's groundwater <br /> cleanup level). This well is also screened across the top of the water <br /> table and not in any of the lower aquifer zones. I think pressure <br /> grouting will be adequate for this well, but require more if you think <br /> it is needed. <br /> Marcus <br /> <<<"Harlin Knoll [EH]" <HKnoll@sjcehd.com> 4/8 8:37a >>> <br /> Hello Marcus. Can the well be pressure grouted or do they need to <br /> overdrill? <br /> Hk <br /> -----Original Message----- <br /> From: Marcus Pierce [mailto:PierceM@rb5s.swrcb.ca.gov] <br /> Sent: Friday, April 04, 2003 2:03 PM <br /> To: Harlin Knoll [EH] <br /> Cc: John.Guzman@dla.mil <br /> Subject: Decom. Well LM037AA at Tracy Army Depot <br /> Hi Harlan, <br /> I assume you are still the person handling the Tracy Army Depot's <br /> permits. If not, please forward this email to the right person. <br /> Anyway, they need to remove monitoring well LM037AA because of <br /> construction activities in the area. I have already concurred with this <br /> action, but we may require a replacement well after the construction <br /> activities have been completed. Let me know if you need anything from <br /> me to process their permit application. Thanks. <br /> Marcus Pierce <br /> 916-255-3233 <br /> 1 <br />
