Yes a current Volatile Organic Compounds (VOC)s sample would be helpful from the <br /> small well. Please instruct the lab to report the results on the state CDPH EDT report format and label the <br /> sample as Small Well, 3901330-002. <br /> Nuel, Mike, and myself also have concerns that once this well is placed back into use it will adversely affect the <br /> on-site plume from the USTs. We also, have concerns about the well at Carl's Restaurant. No one has tested <br /> Carls's Restaurant well for VOCs or BTEX that we know of. Do you have any results for this well? <br /> Whether the LOP UST site is closed or not closed the small well must be destroyed if left inactive. If the well is <br /> placed back into use as a small public water system source, quarterly VOC monitoring will be required for one <br /> year and annual VOC testing thereafter. If it is found that the well tested with detectable levels of VOC <br /> contaminants where there was none detected before or rising concentrations of a detected contaminant,then <br /> the well must be destroyed. <br /> 1'11 let Nuel and/or Mike respond to your comments regarding closure of the site. <br /> Thanks, <br /> Adrienne <br /> From: William Little [mailto:wlittle@advgeoenv.com] <br /> Sent: Thursday, September 22, 2011 1:29 PM <br /> To: Adrienne Ellsaesser [EH] <br /> Cc: Mike Infurna [EH]; Nuel Henderson [EH] <br /> Subject: RE: Cecchini &Giovannini Water System and Cherokee Truck Stop, 3535 Cherokee Road, Stockton <br /> Hello Adrienne, <br /> I have not reported these results you directly, so here is the most comprehensive available <br /> data set for the small well. The well is a four inch steel well with approximately 50 gallons of <br /> water within the well casing. AGE purged 200 gallons and then sampled with grunfos pump. As <br /> you can read, most results are non-detect and one older result is below the MCL for the VOCs. <br /> Also this site has an active UST investigation and an additional sampling event for semi-annual <br /> monitoring is forthcoming soon. An additional sampling of the well can be accommodated, <br /> even a duplicate to ensure any data questions. <br /> Maybe your aware, the USTCF has decided not continue funding corrective action for the site <br /> and placed the site in the "site closeout" designation. If additional work is performed only <br /> a <br /> 9/23/2011 <br /> I <br />
