Good morning all. 1 wed to discuss this site withy <br /> you when you have a chance.... <br /> Since September 2012, an ozone injection system has been operating at this site in Stockton. Fuel contaminant <br /> concentrations in groundwater have generally declined during the operation period. During the second quarter <br /> 2014, benzene levels in groundwater were all reported below the 3,000 <br /> ppb Low Threat Closure Policy threshold <br /> for small plumes for the first time. In the second quarter 2014 monitoring/status report issued a while back,we <br /> recommended collecting one more round of samples, while the ozone injection system remains operational,and <br /> then if concentrations of benzene in groundwater were once again below the 3,000 ppb threshold, moving the <br /> site into a phase of limited post-remediation monitoring before (hopefully) moving the site to closure. In about <br /> 4 weeks, we were planning to collect the next round of samples. <br /> When you get a chance, could you please do a quick review of the site & let me know if you are in agreement <br /> with Stratus' proposed course of action discussed above? In all honesty, we worked with Harlin Knoll on this up <br /> until system start-up, and I don't think I've e-mailed or discussed this site with anyone from San Joaquin County <br /> or the Water Board since this time (nearly 2 years). <br /> Thank you. <br /> Scott. <br /> 3 <br />
