The goal was to generate data on levels of these contaminants in groundwater used for drinking water in the area. Previous testing showed that this part of the state may have potentially elevated levels of arsenic in well water due to leaching from certain arsenic-rich geologic formations. Two hundred thirty-eight wells were sampled. Three quarters of the well water samples contained arsenic levels below 5 μg/L (micrograms per liter). A quarter of the samples were above 5 μg/L, with 3% of wells containing arsenic levels above 10 μg/L. The highest arsenic level observed in this study was 35 μg/L. Few water samples had detectable levels of mercury, and of those where mercury was detected, the levels were trace.en-USNew JerseyNew Jersey - Hunterdon CountyArticle
