A Kleinfelder chain-of-custody form is attached to the cooler. The chain-of-custody form <br /> includes Kleinfeider's name, address and telephone number. the employee 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. The chain-of-custody form is signed by each <br /> Person who handles the satrapies, including all Kleinfelder employees and the receiving <br /> employee of the analytical laboratory when the samples are delivered.

Survey <br /> accuracy is 0.1 foot for the "x' and "y" coordinates and.01 foot for the "z" coordinate. The <br /> depth to static ground water is measured from a set location at t1e top of the FVC casing. <br /> The depth of water is then subtracted from the elevation of the top of the well casing to <br /> provide a ground water elevation for each monitoring well location. <br /> F6-FIELDPRO <br />
