Common use of Metals Clause in Contracts

Metals. Metal analyses were conducted on soil and groundwater. In only one case did the metals exceed the State TTLCs that classify soil as hazardous waste for disposal purposes (Marshack, 1988): refuse subsurface soil sample 7A had a detected value of 3000 ppm lead. Two prior Levi▇-▇▇▇▇▇▇ ▇▇▇surface soil samples (one panhandle and one non-refuse fill area) had detected elevated lead concentrations of 3800 ppm and 2000 ppm McLaren's groundwater analytic results for metals were consistent with Levi▇▇-▇▇▇▇▇▇'▇ ▇▇▇ults. Although the water is brackish at the site, and therefore unsuitable for drinking, the metals detected in the shallow groundwater were generally below California's Maximum Contaminant Levels (MCLs) for drinking water (CDHS, 1989). Only a few metals slightly exceeded the MCLs. McLaren's surface water analytic results for metals did not demonstrate any elevated levels.
