Mike Infurna [EH] <br /> To: tcuellar@advgeoenv.com <br /> Subject: RE: Flag City Chevron <br /> thank you. <br /> -----Original Message----- <br /> From: Timothy Cuellar [mailto:tcuellar@advgecenv.com] <br /> Sent: Tuesday, July 12, 2005 2:40 PM <br /> To: Jim Barton (E-mail) <br /> Cc: Calvin Lee (E-mail) ; Bob Marty (E-mail) ; Mike Infurna [EH] <br /> Subject: Flag City Chevron <br /> Jim - I just received the analytical results from the quarterly ground <br /> water monitoring event (June 2005) . I am attaching some of the results as a <br /> PDF file for your review. Both me and Cal are very concerned with the <br /> recent spike in the MTBE concentrations we are seeing from Flag City <br /> Chevron well MW-2, and wanted to bring it to your immediate attention. <br /> Especially since it is in a downgradient direction and towards San Joaquin <br /> County CSA well no. 2. Basically over the past 4 quarters, MTBE <br /> concentrations at well MW-2 have increased from ND levels (09/04) , to 71 <br /> ug/l (12/04) , to 130 ug/l (03/05) to 220 ug/l (06/05) ; ground water <br /> pump-and-treat operations were suspended in August 2004 . Please call me if <br /> you should want to further discuss.
