Areas in Massachusetts are highlighted in red where PFAS contamination exceeds the state EPA’s acceptable threshold (source, U.S. Geology Survey).

York Analytical Laboratories is now officially licensed by the State of Massachusetts Department of Environmental Protection to perform PFAS analysis in potable water by EPA method 537.1.

York continues to expand its existing licensing and leadership in the northeast region for PFAS analysis in potable water and other matrices – soil, groundwater, wastewater, surface water. In addition to New York and Connecticut, York is now licensed in New Jersey and Massachusetts.

A recent study by the U.S. Geological Survey identified 56 Massachusetts cities and towns where PFAS contamination officially exceeds the standard for PFAS in drinking water, a threshold of 20 parts per-trillion (PPT) set by the Massachusetts Department of Environmental Protection.

The proposed federal threshold by the U.S. Environmental Protection Agency would be much lower at 4 PPT.
