Fish have been tested for mercury in Massachusetts since the 1980’s. So far, 234 waterbodies have been tested, resulting in 97 fish advisories where fish had mercury levels above 0.5 mg/kg. Fish from 113 waterbodies did not contain elevated concentrations of mercury. When mapped, the distribution of fish advisories presents a picture of the history of mercury pollution in the state.
