All samples were analyzed for hexavalent <br /> chromium, total chromium, copper, and arsenic. Field tests were carried <br /> out on all samples for pH, conductivity, and temperature. With one minor <br /> exception, concentrations of chromium, copper, and arsenic were all below <br /> detection limits. The only exception was a copper concentration for sample <br /> No. 4 of 0.04 mg/l, which is negligible in comparison to the drinking water <br /> standard of 1 mg/l. The reported detection limits are: <br /> Parameter Detection Limit (mg/1) <br /> Hexavalent Chromium 0.02 <br /> Total Chromium 0.05 <br /> Copper 0.02 <br /> Arsenic 0.01 <br /> Most of the wells identified during the earlier portion of the off-site <br /> sampling program were found to be plugged, capped, nonexistent, or other- <br /> wise nonoperational. Samples were collected from five operational wells <br /> at the following locations : <br /> Sample Number Address <br /> 1 4749 East Fremont <br /> 2 4801 East Fremont <br /> 3 830 Ellen <br /> 4 3901 East Minor <br /> 5 249 South Dawes <br />
