ME <br /> — ,c" r <br /> x a <br /> f t <br /> the former location of filter I and a new filter installed in <br /> filter 2'$ former location. Testing of the effluent and influent <br /> water will be in accordance with Tri Valley Growers, Waste <br /> Discharge Requirements. <br /> Influent and effluent water (from both carbon filters) was <br /> sampled at the end of the pump test. Xylenes were detected 'In <br /> the sample of the effluent water of the second carbon filter <br /> (TVGT EFF2C); however, xylenes were also detected in the trip <br /> blank sample at nearly identical concentrations. Therefore, the <br /> presence of xylenes in the effluent samole is believed to be <br /> contamination introduced either during transport or in the <br /> laboratory. Crons-contamination during sample collection is not <br /> likely since the trip blank is prepared in the laboratory. <br /> A summary of analytical data is <br /> presented in 1. A sen <br /> round of samples from 2C effluent water (TVGTble EFF2C) willco bedcollected and analyzed to confirm laboratory results. Laboratory <br /> data sheets are included In Attachment 3, <br /> The system Is ready for continuous operation. Permission to <br /> begin operations is requested from the Regional Water <br /> Control Board and San Joaquin Public Health Services.
