Philadelphia, PA, August 13, 2026 —

A recent report released by PennEnvironment reveals that more than half of Pennsylvania’s waterways are contaminated with fecal bacteria, posing potential risks to public health and recreation. The findings highlight significant pollution levels in rivers and creeks across the state, including notable Philadelphia-area water bodies such as the Delaware River and Brandywine Creek.

According to the report, these waterways can reach unsafe levels of fecal bacteria during certain times of the year, making activities like swimming and wading potentially hazardous. This contamination is frequently attributed to the aging infrastructure of combined sewer systems found in older urban areas.

During periods of heavy rainfall, these combined sewer systems are prone to overflowing. When this occurs, untreated raw sewage is released directly into rivers and streams, introducing harmful bacteria and other pollutants. This practice directly impacts the water quality and ecological health of these aquatic environments.

The report notes that while the federal Clean Water Act set a goal of making U.S. waterways swimmable, many older cities, including Philadelphia, face substantial challenges in meeting these standards. The primary obstacle identified is the need to upgrade and modernize decades-old sewer infrastructure.

The specific levels of fecal bacteria and the exact periods of unsafe conditions were detailed in the PennEnvironment report. However, the contractor’s name and the specific timeline for potential infrastructure upgrades were not provided in the summary.
