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 <br /> go to 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: vmccartney(cDsjcehd.com <br /> . n <br /> From: Andrew Dorn (mailto:AndrewDCa gtienv.coml <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 <br /> the Georges'Service site located at 1600 Durham Ferry Road.The air sparge system is <br /> effectively cleaning up the edges of the groundwater plume (near OS-1 and OS-2) however <br /> the core of the plume has not shown a response.There is currently only one (1)air sparge <br /> well operating in the core of the plume(AS-1).We recommend that two (2)additional air <br /> sparge wells be installed within the core of the plume to accelerate remediation.The site <br /> has been granted an additional $40,000 from the Fund to be used prior to July 12013 that <br /> 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 <br /> prior to July 1, 2013? <br /> 5/21/2013 <br />
