Draft 2020 Pennsylvania Integrated Water Quality Monitoring and Assessment Report

Summary of Study

The Commonwealth of Pennsylvania released its fourteenth report in a series prepared for the federal Clean Water Act. The report addresses the state's rich aquifers: over 85,500 miles of rivers and streams that connect over 700,000 acres of lakes, bays, and wetlands. Protection of this diverse water system remains a challenge.

Today, one out of every 3 miles of rivers and streams has impaired water quality. The number of impaired miles has grown by 5,568 miles since the 2018 assessment. Indeed, over 25,000 miles--30 percent--failed to meet crucial standards, such as consumption and aquatic life. In addition, one out of every 8 miles of streams and rivers are deemed unsafe for recreation.

The top sources statewide for water pollution are agricultural runoff, abandoned mines, and stormwater. Since 2016, however, 26 streams, rivers, and lakes were fully resored for aquatic life.
