The important distinction
A city report is not the same thing as your faucet.
This is a strong model page for connecting system-level water reports with actual at-the-tap lead sampling language.
PWD system data is citywide; lead exposure is still evaluated through property plumbing and lead service-line sampling.
What to check first

Use cold flushed water and certified filters for sensitive households while waiting for property-specific answers.
Check PWD’s lead plumbing resources before assuming a citywide report answers an individual tap question.

Frequently Asked Questions
Is tap water in Philadelphia, Pennsylvania safe to drink?
Philadelphia has unusually useful official pages because PWD publishes both water quality reports and lead sampling results, including a 2025 lead testing table. This page does not issue a medical or legal safety guarantee. It points you to the official public-water-system report and the address-level checks most likely to change what comes out of a specific tap.
Why can my tap water seem bad if the city report looks good?
A city or utility report mainly describes the public water system. Your tap can still be affected by service-line material, older building plumbing, fixtures, stagnant water, water heaters, filters, or recent plumbing work.
What should renters or Airbnb guests check first in Philadelphia?
Read PWD’s current water quality report and lead sampling results together. If the building has lead plumbing or is older, request a home lead test or documentation from the property manager.
