Tiny shells, big sign. 🦪

Freshwater mussels are showing up in Pittsburgh-area waterways, and that's exciting news.

Why? Because mussels are sensitive to pollution and can help indicate improving water quality. Their presence is one of many signs that our rivers are healthier today than they were decades ago.

Cleaner rivers don't happen overnight. They happen through years of investment, collaboration, science, stewardship, and people who care deeply about protecting our waterways.

Shoutout to our regional partners, researchers, environmental organizations, municipalities, and agencies working every day to improve water quality throughout our watershed.

This is a win worth celebrating. 🙌
