Nuel.Henderson recommended immediate <br /> resampling of these MWs to confirm the ground water results for the lastest round and then go to quarterly <br /> sampling, if appropriate. <br /> Postponement of injection in this area seems-warranted, until,more data is available and reevaluated. <br /> HARLIN KNOLL <br /> SAN JOAQUIN COUNTY/EHD <br /> 600 E MAIN STREET <br /> STOCKTON, CA 95202 <br /> (209)468-3442 <br /> FAX: 468-3433 <br /> From: Chris Strong [mailto:cstrong@wgr-sw.com] <br /> Sent: Tuesday, August 31, 2010 10:08 AM <br /> To: Harlin Knoll [EH] <br /> Ce: 'Jim Neal WGR' <br /> Subject: Third Quarter UST#3 Sampling and Remediation Activities <br />'h Hi Harlin, in follow-up to our phone conversation this morning,.I just wanted to confirm county approval for <br /> the details we discussed regarding the UST#3 site at the Port of Stockton (T0607711817). In response to <br /> our 8120110 letter to the county, you said you were OK with the sampling of the two extra wells; MW3-6 and <br /> MW3-9, this quarter in addition to the MW3-8 well,which we have already been sampling on a quarterly <br /> basis. This is in order to better assess downgradient natural attenuation trends and temporarily hold back <br /> i on installing the downgradient dissolved oxygen injection system unless natural attenuation proves <br /> insufficient. We will plan to go ahead and sample wells MW3-6, MW3-8 and MW3-9 this quarter and will <br /> still be installing the Ozone-Peroxide Pilot system at the core of the plume, as approved in the 7130110 <br /> SJCDEH comment letter. <br /> L Regards, <br /> Chris Strong, PG <br /> Senior Geologist <br /> WGR Southwest, Inc. <br /> 315 W.
