Fish Mercury Research Data Portal

The Massachusetts Department of Environmental Protection monitors contaminant levels in the edible tissues of freshwater fish with two programs: the research program, and the public request sampling program. The data available through this portal come from the research program, which intensively monitors fish mercury levels in 39 lakes to track changes in fish mercury with time. (See "For More Information" below). The Data Portal provides:
  • Individual fish tissue mercury concentrations
  • Sediment quality data
  • Water quality data.
A chronology of DEP’s fish mercury monitoring program and reports of the Environmental Monitoring projects that produced the data are available on MassDEP’s website. There are two options for retrieving data on fish tissue mercury, water quality, or sediment chemistry from the research lakes:



If desirable, download data into workbooks for further processing.
