About STEEP's Private Well Study

Sources, Transport, Exposure & Effects of PFAS (STEEP) is a Superfund Research Program led by the University of Rhode Island in partnership with the Harvard T.H. Chan School of Public Health’s Department of Environmental Health and Silent Spring Institute. STEEP is funded by the National Institute of Environmental Health Sciences (NIEHS) Superfund Research Program to address the emerging problem of PFAS contaminated sites across the U.S. and elsewhere. STEEP is engaging communities on Cape Cod, Massachusetts, to address local PFAS contamination issues. Our local community partners include Massachusetts Breast Cancer Coalition, the Sierra Club Cape Cod Group, and the Mashpee Wampanoag Tribe.
