PA Streams Recovering: Nature's Cleanup Crew at Work
28 Nov
Summary
- Nature-based solutions like rain gardens improve water quality.
- Restoration efforts have brought fish back to Montour Run.
- Abandoned mine drainage systems remove tons of pollutants annually.

More than 80,000 miles of streams and rivers in Pennsylvania are showing signs of recovery, particularly in Allegheny County, where pollution from erosion and stormwater runoff has historically been a major issue. The Allegheny County Conservation District (ACCD) has been implementing innovative, nature-based solutions for over 15 years to combat these challenges and improve water quality for local communities.
One such initiative is a rain garden in Findlay Township, designed to capture and naturally filter stormwater runoff before it enters the water supply. This approach not only enhances water quality but also helps reduce water treatment costs. The ACCD has also prioritized addressing abandoned mine drainage and stormwater runoff in the Montour Run Watershed, recognizing the significant impact heavy rains can have on polluting waterways with various contaminants.
These dedicated efforts are yielding visible results. The creation of the Milk Run AMD system has successfully removed tens of thousands of pounds of acid and aluminum annually. Consequently, Montour Run now supports a healthy ecosystem, with fish populations, including stocked trout, making a comeback. The ACCD observes an overall improvement in regional water quality and anticipates continued progress through collaboration with environmental partners.
