DEP: Number of polluted waterways in Pa. up

The Pennsylvania Department of Environmental Protection says a third of the state’s streams are impaired or polluted — meaning those waterways are unsafe for aquatic life, recreation, fish consumption and water supply. All told, Pennsylvania has 27,886 miles of streams that are impaired — almost 2,400 more than in 2020.

The<a href=”″> draft 2022 Integrated Water Quality Monitoring and Assessment Report</a> is updated every two years as part of the 50-year-old Clean Water Act.

The report indicates that abandoned mine water runoff, agricultural runoff and storm water runoff are the three biggest sources of pollution.

Eighty-nine percent of Lancaster County’s streams are impaired putting the county near the top of the counties with the highest percentage of polluted streams. More than half the streams in Dauphin, Berks, Cumberland, Franklin, and York Counties are impaired, according to the report.

Dustin Shull, Manager of Assessment Section in the Bureau of Clean Water at the Pennsylvania Department of Environmental Protection is on Thursday’s <em><strong>Smart Talk</strong></em> with more information.
