>>> "Mike Infurna [EH]" <Mlnfurna@sjcehd.com> 9/19/2011 11:54 AM >>> <br /> Jim, <br /> Friday was a day off for the person I needed at ATC to discuss this site. <br /> Just so you know, Stantec was with this site thru March 2011. The six month ozone pilot test ended <br /> March 2011. In April ATC, Mr. Ben Chevlen took the site over. There have been NO gw sampling <br /> events since March 23, 2011. One is scheduled for Sept 21, 2011. <br /> The ozone iscurrently OFF and has been since end of March 2011. It will stay off until we can <br /> determine if the Mn detections are linked to the ozone injections. Stantec and ATC seem to think <br /> they are not. I have my doubts especially since pre-pilot Mn was ND and during the pilot the Mn <br /> spiked as high as 13,000 ug/I . <br /> Be that as it may, if the EHD has anything to say about restarting the ozone, I will require MONTHLY <br /> gw sampling and ozone injection rates to change so as to equilibrate the formation of Mn in the core <br /> area to ensure that the Mn gw concentrations are < MCLs or at acceptable levels in the sentinel <br /> wells. <br /> Based on the gw data from this next gw event, they will either submit a workplan for full RAP or re- <br /> pilot test the ozone...or, option 3 (to be determined later). <br /> Mike. <br /> -----Original Message----- <br /> From: Jim Barton [mailto:jbarton@waterboards.ca.gov] <br /> Sent: Friday, September 16, 2011 1:48 PM <br /> To: Mike Infurna [EH] <br /> Subject: RE: Circle K, 16470 Cambridge Rd., Lathrop, San Joaquin Co. <br /> I would appreciate it, Mike.

But if you need an answer now, I <br /> can call the PM at Stantec and see what's up. <br /> If it can wait, I'll add it to my list of lower priorities... <br /> mike <br /> -----Original Message----- <br /> From: Jim Barton [mailto:jbarton@waterboards.ca.gov] <br /> 2 <br />
