Most people never see them, but freshwater mussels are some of nature's hardest-working conservation heroes.

Did you know that nearly 70% of Pennsylvania's freshwater mussel species are endangered? These remarkable creatures help keep our rivers healthy by filtering contaminants from the water and serving as indicators of ecosystem health.

This video highlights aquatic biologists, divers, and snorkelers working together on the Allegheny River to survey endangered mussel populations, learn species identification techniques, and support conservation efforts that help protect these vital species for future generations.

Healthy mussels mean healthier waterways for wildlife and people alike. 🌊🐚

Now’s the perfect time to winterize and save.

Under the Shapiro Administration, The Pennsylvania Department of Environmental Protection’s Bureau of Clean Water has significantly expanded the state’s understanding of emerging contaminants through its Water Quality Monitoring Program.

Over the past five years, DEP’s collaboration with the @USGS has generated first‑of‑its‑kind data on PFAS sources, movement, and behavior in Pennsylvania’s surface waters, filling long‑standing scientific gaps.

As noted by Joseph Duris of the U.S. Geological Survey, this longstanding partnership has enabled influential research spanning more than three decades, and recent efforts have been especially impactful in advancing statewide PFAS knowledge. These findings are now helping shape more informed water‑quality strategies, strengthen public‑health protections, and guide future monitoring and remediation priorities.
