Study finding rampant 'forever chemicals' leads to increased water monitoring across Pa.
More monitoring efforts are underway on Pennsylvania waterways after a study revealed so-called "forever chemicals" are present in some streams and lakes.
The results of a joint study by the United States Geological Survey and Pennsylvania Department of Environmental Protection determined 122 of 161 Pennsylvania rivers and streams tested for polyfluoroalkyl substances contained at least one of these chemicals, known as PFAS.
The DEP on Tuesday said it is ramping up existing efforts to monitor water resources and using the study to develop standards for surface water.
Based on the study’s results, the DEP reports it updated its surface water monitoring strategy for PFAS and is taking more frequent samples in areas of concern.
The study results announced this year were based on samples collected in 2019.
What are PFAS?
PFAS are a group of synthetic chemicals used in a wide variety of common applications, from food packaging and non-stick cookware, to fire-fighting foams and materials that are resistant to water grease or stains. Decades of widespread use of products containing PFAS has resulted in elevated levels of environmental pollution and exposure in some areas of the state.

What other steps are being taken?
The DEP is a planning to begin a monitoring program that would require some wastewater treatment plants to monitor for PFAS discharges. The effort will help the agency track where PFAS chemicals may be entering Pennsylvania’s rivers and streams through wastewater treatment plant discharges, which may include wastewater discharges from industrial entities known or suspected to discharge PFAS in their waste streams.

One fish consumption advisory for Neshaminy Creek was issued as a result of the study and the DEP will continue to collect additional fish tissue samples and update fish consumption advisories as needed.
Sara Breitmeyer, a USGS chemist and lead author of the study, said these chemicals are found in waterways across the world. “People should be aware that it’s in the water. The study was a baseline study just to see what types of PFAS exist in Pennsylvania surface waters and spread out over the state,” she said.
“This joint venture produced the first study of its kind in the nation, and associates PFAS in surface waters across a state with upstream activities that might be sources of the contaminant. This study has expanded our understanding, and will assist in determining what steps need to be taken in addressing issues associated with this emerging contaminant,” Rich Negrin, DEP secretary, said in a news release. “Our findings have already helped, and will continue to help, guide DEP’s actions regarding where to focus resources on identifying, tracking, and addressing potential sources of PFAS contamination.”
Where PFAS concentrations were highest in Pennsylvania
Breitmeyer found 56 Pennsylvania-area streams that had total PFAS of at least 10 nanograms per liter (parts per trillion).
