Pennsylvania Annual Drinking Water Compliance Report
The U.S. Environmental Protection Agency (EPA) requires states produce an annual report on public water system compliance. PA DEP creates a report each year that includes a summary of the incidence of Pennsylvania public water system (PWS) maximum contaminant level (MCL), maximum residual disinfectant level (MRDL), significant monitoring/reporting (M/R), treatment technique (TT), consumer confidence report rule (CCR), and public notification (PN) violations for the previous calendar year. The level of compliance and efforts being undertaken to provide safe drinking water to the residents and travelers of Pennsylvania are also highlighted in the report.

  • Consumer Confidence Reporting System website generates dynamic reports on detections and violations to assist community water systems in preparing their annual Consumer Confidence Reports on quality of drinking water. The source of the information is the Pennsylvania Drinking Water Information System (PADWIS) maintained by DEP Bureau of Safe Drinking Water's PADWIS Section. Data for the next calendar year will be available on March 1st. The violation reports contain self-monitoring violations for contaminants useful in preparing the CCR.
