Source Water Assessments

Completed in 2002, the Delaware River Source Water Assessment (SWA) was created in response to the 1996 SDWA Amendments, which call for the assessment of all source water supplies across the U.S. to identify potential sources of contamination. PWD, along with its project partners, conducted a watershed-based, multi-phase assessment that identified and prioritized potential and existing sources of contamination and evaluated the vulnerability of the water supply to these contaminant sources.

The Source Water Protection Plan (SWPP), completed in 2007, establishes a set of priority actions to address threats to the water supply identified during the assessment phase. The plan’s recommended actions items are based upon a holistic watershed approach that recognizes the interconnectedness between source water protection concerns, upstream land and water use, and the need to maintain a healthy aquatic ecosystem. Upon completion of the protection plan, PWD became one of the first water suppliers in the state to meet all steps outlines in the Pennsylvania Department of Environmental Protection’s (PADEP) minimum criteria for Source Water Protection Program.

Drinking Water Quality Reports

Every year PWD publishes an annual drinking water quality report. The report is mailed to every resident in the city and contains a wealth of information regarding the source, safety and contents of the City’s drinking water, as well as Philadelphia’s source water protection efforts.
