The chain of-custody forth <br /> includes Kleinfelder's name, address and telephone number, the ctnpioyee number of the <br /> individual who performed the sampling, the sample numbers, the date and time the <br /> samples were collected, the number of containers each sample occupies, and the analyses <br /> for which the samples are being submitted.

Survey <br /> accuracy is 0.1 foot for the "x" and' +"coordinates and.01 foot for the T coordinate. The <br /> depth to static ground water is measured from a set location at the top of the PSC casing. <br /> The depth of water is then subtracted from the ciavatou of the top of the well casing to <br /> _i provide a ground water elevation for each monitoring well location. <br /> �*7 <br /> f <br /> i <br /> Ew <br /> t F6-I DPR© <br />
