Pinkertons Run Abandoned Coal Mine Pollution Clean-up and Streambank Stabilization

Mine pollution


The Allegheny County Parks Foundation is working toward the goal of cleaning Pinkertons Run of abandoned mine pollution so that one day it can be stocked with native fishes and enjoyed for sport. Since 2014, ACPF has partnered with Trout Unlimited to study the environmental impact of pollution coming from old coal mines in the park and mitigate its effects. Biological data gathered over the course of many months has provided an overview of organisms living in the stream and helped gauge the outcome of a remediation strategy. In 2018, PA DEP made a Growing Greener Grant to ACPF to design and construct a passive treatment system for the worst discharge and design is underway. Since that time, other grants have been procured that will make this project a reality. This project also includes plans to stabilize the streambank along Pinkertons Run. See our conceptual plan.

The project design drawings are underway and will be completed mid 2021. This project is now fully funded and is expected to be bid in late 2021. Construction is expected to take place in 2021-2022.
