{ <br /> Page 2 of 3 <br /> I read the recommendations in the MW install and QMR about the UST you think is <br /> north of the MW5's.. <br /> wouldn't get your hopes up, but I'm making an apt with my Geo to discuss it. Put <br /> yourself in this landowners position for a moment. Your neighbor gets the EHD on <br /> you to investigate a possible UST in the sidewalk because you think it's affecting <br /> your investigation??? my experience has shown, little to no cooperation w/o proof. <br /> either way, I'll be generating a response letter and I'll include our <br /> thoughts/comments on it. <br /> don't stop progressing on the site until this ghost UST thing is settled. Whether <br /> there's a 'source' or not north of MW5's, your contam at MW-2 is real and too high to <br /> leave in place unremediated. plan on a PAR or SCM to discuss fully the nature and <br /> extent of the plume. I'm interested in your 'delineation' conclusions in the 'core' <br /> area. <br /> With MW-2 and 2A both exceeding gw concentration concerns for doing nothing, <br /> you're still not vertically defined in this core area. Plus, older C-3 had deep gw hits of <br /> concern back in Nov 07 and now C-6, and C-8 have elevated gw hits too and <br /> no MW is close so stopping progress now is not a good idea. <br /> you'll need to be defined to start a corrective action unless you feel (and can prove) <br /> interim remediation is warranted. I see no treat to sensitive receptors, do you? so <br /> plan on delineation work to continue and all the time think remediation alternatives. <br /> be sure to include soil and gw iso-con maps for each depth of concern in <br /> reports/SCMs...(first and A zone)... <br /> give me a call if you want to talk. <br /> also, call me for apt to do First QM- 2009... <br /> From: Anderson, Paul [mailto:PAnderson@pscnow.com] <br /> Sent: Tuesday, February 24, 2009 9:27 AM <br /> To: Mike Infurna [EH] <br /> Subject: Reply to voice Mail (1st QMR 2009) - Global ID # T0607700632, Case #2371, Sara Lee 1717 <br /> South Center Street, Stockton <br /> Mike, <br /> I just received your voice mail today. I was out of the office last Friday and yesterday. <br /> Your voice mail was with regard to the various non-standard analytical constituents that <br /> were performed during the first quarterly event of 2009. <br /> We decided to include these parameters at the last minute as a means to gather some <br /> information regarding natural attenuation for the site. <br /> We also wanted to use the additional information to assist in determining remedial <br /> alternatives as part of a subsequent feasibility study / remedial evaluation for the site. <br /> Obviously, there is residual contamination, perhaps even some off-site source <br /> contamination coming onto the property. <br /> Performing the natural attenuation parameters during the first quarter was a means to <br /> simply gather some additional information. <br /> 2/25/2009 <br />
