In December 2025, the Pennsylvania Department of Environmental Protection (DEP) released a draft report showing that 37% of the state’s stream miles are impaired, an increase from 34% in the previous report. Main impairment sources include agricultural runoff, acid mine drainage (AMD), and urban runoff. The hearing aimed to explore improved strategies to address these issues.
Key comments from witnesses highlighted Pennsylvania’s advanced water quality assessment programs, which inform pollution limits and prioritize human health, especially for drinking water. The DEP has identified significant restoration success stories, particularly in Lake Erie, and emphasized the need for continued nonpoint source pollution reduction.
Concerns were raised about federal funding cuts impacting water quality monitoring and restoration efforts, as the availability of federal funds is expected to decline soon. Experts stressed the importance of targeted monitoring, especially in environmental justice communities, and suggested operationalizing TMDL (Total Maximum Daily Load) development for AMD-impacted waters.
Calls for more comprehensive strategies included enhancing pollution reduction practices across both agricultural and urban areas and addressing emerging contaminants like microplastics and PFAS. The hearing concluded with Rep. Greg Vitali emphasizing the need for adequate funding and resources for the DEP to effectively address water quality challenges in Pennsylvania.
