The Agency for Toxic Substances and Disease Registry, or ATSDR, released a draft assessment on the effects of certain chemicals in drinking water.

Last month, Fitzpatrick demanded EPA Administrator Scott Pruitt release the study on the human health effects of PFAS, or perfluoroalkyls.

The 429 page report reveals humans exposed to increased levels showed an increase in cholesterol levels and higher risk of thyroid disease, decreased fertility, lower birth weights, liver issues, and decreased effectiveness of vaccines.

In July of 2017, Fitzpatrick spoke on the house floor about the Warminster military base that was one of 400 tested for contamination. The recent study found levels of PFAS in the area’s water supply are at least seven times higher than the minimal risk level.

Director of the Office of Ground Water and Drinking Water Dr. Peter Grevatt released a statement on behalf of the EPA.

“Addressing Per- and polyfluoroalkyl substances (PFAS) is one of EPA’s top priorities and the agency is committed to continuing to participate in and contribute to a coordinated approach across the federal government,” Dr. Grevatt said. “EPA looks forward to continuing to collaborate with ATSDR and all of our federal partners as we work together to protect public health.”

The EPA held a National Leadership Summit in Washington, D.C. last month, during which EPA Administrator Scott Pruitt pledged to take steps to address PFAS. These include designating the chemicals as “hazardous substances,” developing groundwater cleanup recommendations, and designating a maximum contaminant level.

PFAS can be found in food, household products like paints and cleaning supplies, and drinking water. It is currently believed PFAS accumulate over time and do not exit the body.

Fitzpatrick, along with Congressman Brendan Boyle, is increasing pressure on the EPA to take action immediately on PFAS. The Congressmen will be hosting a joint press conference Monday morning.
