The wells which <br /> currently are justified for sampling are well MW-5 (down-gradient of the former UST area 30 feet)and well MW- <br /> 8 (UST area). The ground water samples should be analyzed for TPH-g and VOCs (inclusive). <br /> The rain events,duration and amount(within the past month)will likely to be negligible on the current water <br /> table level. The wells installed last year have the minimal amount of water required to sample. The depth to <br /> ground was approximately 65 feet during the last quarterly event; within the well screens (well MW-1 will likely <br /> be dry). <br /> The sampling of the wells and monitoring of depth to ground water from the wells represents a scope which the <br /> responsible party can fiscally manage(the site is currently vacant). If the USTCF liberates funds owned the client, <br /> then future sampling could occur. The EHD has already comment on the necessity to remediate the site (please <br /> refer to your letter attached). <br /> There is no current reason to sample wells that are non-detect and outside the plume (well MW-4 up-gradient 95 <br /> feet,well MW-6 up-gradient 50 feet,MW-7 up gradient 60 feet)until a closure consideration from you office <br /> have been issued. <br /> AGE will be on-site in the late morning. <br /> William Little <br /> California Professional Geologist#7473 <br /> wlittle@advgeoenv.com <br /> 1(800) 511-9300 <br /> Advanced GeoEnvironmental Inc. <br /> 837 Shaw Road <br /> Stockton, Califorina, 95215 <br /> 1(209)467-1118 facsimile <br /> From: Vicki McCartney [EH] [ma iIto:vmccartney@sjcehd.com] <br /> Sent: Tuesday, February 10, 2009 3:13 PM <br /> To: William Little <br /> Subject: RE: Moore Truck Lines <br /> Bill. <br /> Nuel and I have reviewed the fourth quarter 2008 report for Moore Truck Lines and have concluded that <br /> groundwater samples should be collected from monitoring wells MW-1, MW-5, MW-6, MW-7, and MW-8 during <br /> the scheduled sampling event tomorrow. Based on the recent amount of rainfall,these wells should not be dry. <br /> 2/11/2009 <br />
