STEEP is a research project that is addressing a class of chemicals called PFAS in drinking water. The project is led by the University of Rhode Island, in partnership with the Harvard T.H. Chan School of Public Health and Silent Spring Institute. Community partners include Sierra Club Cape Cod Group and Massachusetts Breast Cancer Coalition.

PFAS chemicals are among the most ubiquitous synthetic chemicals in the world – companies add these chemicals to nonstick, stain-resistant, and waterproof consumer products such as carpets and upholstery, waterproof clothing, cookware, food packaging, and even some dental floss. They are also used in firefighting foams and industrial processes. PFAS have been found in public water supplies across the U.S., including in Hyannis and Mashpee.

To better understand the extent of people’s exposure to PFAS in drinking water and to identify potential sources, STEEP has been testing private wells on Cape Cod through its private well study. Over the course of the study, the team has been sharing results with study participants, members of the community, and local officials.

STEEP researchers have also organized and attended many community events on the Cape to share information on PFAS as well as findings from STEEP’s other PFAS studies on Cape Cod. The team has produced a number of resources to help people reduce their exposures to PFAS, lower their chemical footprint, and protect Cape Cod drinking water.
