Don Light never notified me of the <br /> sampling event and had Jenny not informed me by email on 7 April 2013, 1 would not have known to go to <br /> the site on that day. Please keep me informed of any fieldwork at this site. <br /> Thank you. <br /> Vicki McCartney, Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> 1868 East Hazelton Avenue <br /> Stockton, California 95205 <br /> Phone: (209)468-9852 <br /> Email: vmccartnev cDsicehd.com <br /> s; <br /> •�I <br /> From: Andrew Dorn [mailto:AndrewD@otienv.com] <br /> Sent: Friday, May 10, 2013 4:04 PM <br /> To: Vicki McCartney [EH] <br /> Cc: Jenny Weese; Ray Kablanow <br /> Subject: George' Service - 1600 Durham Ferry Road,Tracy <br /> Good Afternoon Vicki, <br /> I am contacting you in regards to the air sparge remediation system currently operating at the <br /> Georges' Service site located at 1600 Durham Ferry Road.The air sparge system is effectively <br /> cleaning up the edges of the groundwater plume(near OS-1 and OS-2) however the core of the <br /> plume has not shown a response.There is currently only one (1) air sparge well operating in the <br /> core of the plume(AS-1).We recommend that two (2) additional air sparge wells be installed <br /> within the core of the plume to accelerate remediation.The site has been granted an additional <br /> $40,000 from the Fund to be used prior to July 12013 that would cover the cost of the work. <br /> What would need to be done on our part to get these two (2) additional air sparge wells prior to <br /> July 1, 2013? <br /> Thank you and enjoy your weekend, <br /> 5/17/2013 <br />
