The portion of the sample used for VOC analyses will be removed from the <br /> bailer using the VOC subsampler provided by the bailer manufacturer. All subsamples <br /> will be placed in appropriate containers in the field„ labeled, avid then stored in an ice <br /> chest pending immediate delivery to laboratory in Sacramento. Caoundwater will he <br /> analyzed for the parameters specified in Monitoring and Reporting Program 71-37. A <br /> duplicate sample will be taken from one of the wells on two occasions per year. It will be <br /> presented to the laboratory as an independent sample from a different source. <br /> lHL Water level (Measurement <br /> The reference point elevations for groundwater elevation measurements will be surveyed <br /> to the nearest 0.01 foot. Depths to groundwater wrll be measured with a 2-wire sounder <br /> to the nearest 0.01 foot. Thus, the computed groundwater elevations wilt be reported to <br /> the nearest 0.01 foot. Water level measurement is the first task upon arriving at the wells <br /> for a round of sampling. The time of measurernecn is noted on the field data sheet. The <br /> groundwater gradient will be computed from depths to water measured in the three wells. <br /> After determining the gradient in four successive quarters additional well(s) may be <br /> recommended if the original three are found unsuitable for detecting groundwater <br /> impacts of the disposal areas. <br /> 1. Expected Schedule <br /> It is expected to drill and construct the wells on Decernber 21 and 22. The wells will be <br /> developed at least 24 hours after grouting. <br /> Please direct your comme roposal to the undersigned at(530)756-2288. <br /> QQ,0fg� • .,.. , <br /> Sincerely yours, ko r' \ <br /> �2'rchard Arnrstr ph. .; <br /> Principal Scientist rr" CrV �P <br /> �lF OF CAl1F��? <br /> Vince Westphal, Sear Creek Winery, 11900 N.
