Why read the Drinking Water Quality Report?

Here are four reasons:

  • Peace of mind: Based on data collected by our Bureau of Laboratory Services throughout 2019, the results show Philadelphia’s drinking water meets, or is better than, all state and federal water quality standards.
  • It's your right to see this data: The U.S. Environmental Protection Agency (EPA) requires all water utilities to produce and distribute water quality testing results on an annual basis — which means we are held to a higher standard than bottled water providers.
  • Lots of smart people made it happen: Philadelphia’s report is produced by a team of experienced scientists and engineers who test the city’s drinking water for nearly 100 compounds, thousands of times each month. Additional monitoring is conducted 24/7 at sites throughout the city.
  • You can help others and share it! We ask you to let others know about the report, especially those who may not have received a notice directly, such as people in apartments and nursing homes, school leaders, and businesses. You can also help by posting a notice in a public place or by requesting extra copies to share with community members.
