C <br /> Ground Water Sampling <br /> ' • The two water supply wells at the Joe Da Silva Dairy were sampled to determine the <br /> PP Y avy p <br /> baseline concentrations of nitrate and total dissolved solids. The water samples from these <br /> two wells were transferred under chain of custody to A& L Western Agricultural <br /> Laboratories in Modesto. Analyses for Calcium, Magnesium, Nitrate, Total Dissolved <br /> Solids, Hardness, Electrical Conductivity, pH; as well as DBCP and EDB were run on <br /> these samples <br /> Ground Water Sampling <br /> t <br /> Five water supply wells in the vicinity were sampled to determine the baseline <br /> concentrations of nitrate and total dissolved solids. DBCP and EDB were also determined <br /> for three of the wells. The wells that were sampled were as follows: <br /> Cross gradient well (sample TVW4) in the SW 1/4 of Section 10, T. 1 S., R. 9 E. <br /> t Downgradient OID irrigation well(sample TVW-5)located at the common corners of <br /> Sections 3, 4, 9 & 10, T. 1 S., R. 9 E <br /> Upgradient private well at the Taro ranch (sample TVW-3) located in the NW 114 of <br /> Section 14, T. 1 S., R. 9 E f <br /> Cross gradient well (sample TVW-1) located at the Eck residence, located in the SW 1/4, <br /> SEI/4, Section 15, T. 1 S., R. 9 E. )h <br /> Cross gradient well (sample TVW-2) located on the Trimble ranch, in the SW 114, SE <br /> 1/4, Section 11, T. 1 S., R. 9 E.. <br /> Water samples from these five wells were transferred under chain of custody to A& L <br /> Western Agricultural Laboratories in Modesto, where they analyzed zed for nitrate and <br /> Y <br /> total dissolved solids. Samples from TVW-3,4 & 5 were also analyzed for total and fecal <br /> coliform, calcium, magnesium, pH, total hardness, electrical conductivity, EDB and <br /> DBCP. <br /> Reference map at appendix II A for locations. <br /> Reference appendix IV A for test results_ <br /> Western Design/David Avila 2000 35 <br /> h <br />
