There is a STANTEC O&M 1 Q-2011 report of the pilot test work that was <br /> addressed to you and on my GT pending list...I rec'd it May 23, 2011. 1 did not comment on it. <br /> I did receive ATC's 2ndQ-2011 report of for the SVE system due to restart soon... <br /> This site can go a few ways with ATC after the Sept 2011 gw data is in and evaluated; 1-if the Mn <br /> has attenuated, they can recommend Ozone as the full RAP and implement as is (many injection <br /> wells are already installed) or <br /> 2- they can send in a workplan to install more wells to better enact a RAP or, <br /> 2- they do NOT recommend Ozone and plan to send in an alternative remedial plan/pilot or, 3-they <br /> would like to re-pilot the ozone using different parameters/flows/etc and maybe find a happy medium <br /> between high flow ozone and Mn formation. <br /> Either way, turning any Ozone on requires an EHD approval first. And I haven't given it yet. <br /> mike <br /> -----Original Message----- <br /> From: Jim Barton [mailto:jbarton@waterboards.ca.gov] <br /> Sent: Monday, September 19, 2011 12:06 PM <br /> To: Mike Infurna [EH] <br /> Subject: RE: Circle K, 16470 Cambridge Rd., Lathrop, San Joaquin Co. <br /> Hi Mike, <br /> Thanks for the update. <br /> Typically oxygenation results are reversed as the source of oxygen is removed. It would also make <br /> sense this sampling event to see if Mn concentrations have reversed since March, which would <br /> provide some data to determine if ISCO is to blame for the increases. <br /> They need to let me know soon (this week) if they anticipate restarting the system, as there will be a <br /> bill sent out in October for the permit. <br /> Jim <br /> James L.L.
