The pilot test has been interrupted by long delays <br /> with limited run time and there is little data available at this time to confidently evaluate the method effectiveness. <br /> The January 2014 sampling event was conducted after only 10 days of run time, the limited June sampling event <br /> was conducted after only 30 days of run time following a 3-month operational hiatus. A complete sampling event <br /> is planned for next week. <br /> The consultant provided data tables to me that include the limited June 2014 sampling event, conducted as part <br /> of the monitoring and reporting program for the WDR. The consultant interprets the data for well MW-5A as <br /> demonstrating a beneficial effect on contaminant concentrations, but I note that there are several long-term <br /> waxing and waning trends in the data and cannot discard the possibility that the recent MW-5A data is part of a <br /> natural waning trend. I have attached the table sent me by the consultant. <br /> The consultant points out that the work so far is part of a 6-month pilot study and he feels the problems have been <br /> worked out to limit interruptions to the operation. In view of the investment made to date, I recommend that you <br /> approve the monies to operate and report on the pilot test for the 6-month period and then determine future action <br /> based on the results. <br /> Call or email me with any questions. <br /> Nuel Henderson, PG <br /> (209)468-3436 <br /> From: Angelica Sandoval Marin [EH] <br /> Sent: Tuesday,July 29, 2014 2:19 PM <br /> To: Nuel Henderson [EH] <br /> Subject: FW: Claim 12186 - Fernando's Place (1201 Center St. S., Stockton) <br /> Not sure if you responded to this email? <br /> Angelica Sandoval Marin,Senior REHS <br /> San Joaquin County, Environmental Health Department <br /> 1868 E.
