Units shown in <br /> mg/L. <br /> 3=Screening levels for soil constituents were established based on available California Human Health Screening Levels(CHHSLs;Cal EPA,2005). Units shown inµg/kg. <br /> °=The California MCL for arsenic is 0.01 mg/L;however,arsenic concentrations as great as 0.018 mg/L have been reported in drinking water wells throughout the Manteca area and likley represent background concentrations. <br /> Geosyntec Consultants,Inc <br /> Page 1 of 1 <br />
