Is Philadelphia tap water safe to drink?
Philadelphia Water Utilities delivers tap water that earns a grade of D (62/100) from TapWaterSafety.org — a below-average rating, with multiple concerns including pfas contamination.
The utility serves 1,584,000 residents in Philadelphia, drawing from surface water (Schuylkill/Delaware Rivers) and disinfecting with chloramine. Despite being legal under US EPA standards, this water would fail the European Union's Drinking Water Directive, primarily due to pfas contamination.
Public testing data identifies 18 contaminants in this water above EWG's health-based guidelines, including: PFOA, PFOA, PFOA, Haloacetic Acids (HAA5), Haloacetic Acids (HAA5), Haloacetic Acids (HAA5), Total Trihalomethanes (TTHMs), Total Trihalomethanes (TTHMs), Total Trihalomethanes (TTHMs), Chromium-6 (Hexavalent), Chromium-6 (Hexavalent), Chromium-6 (Hexavalent), Nitrate, Nitrate, Nitrate, Lead, Lead, Lead. For most residents, a properly certified home filter at the kitchen tap is the most cost-effective way to reduce exposure to whatever's in your water. See our filter recommendations below, matched specifically to this utility's contaminant profile.
Quick actions for Philadelphia residents
Top concerns in this water
Based on the most recent EPA and EWG data, these are the most significant water quality issues for Philadelphia Water Utilities.
PFAS contamination
Severe concernPFOA, PFOA detected. PFAS are persistent chemicals linked to cancer and immune effects with no known safe exposure threshold.
Lead detected in source water
Severe concernLead detected at 4.1 ppb. EWG considers no level of lead safe; EPA's action level is 15 ppb.
Chromium-6 detected
Moderate concernChromium-6 detected at 0.55 ppb.

Recommended water filters for Philadelphia
Filters matched to the specific contaminants in this water supply.
Filter certified for PFOA/PFOS (NSF/ANSI 53 or 58)
$180-$750Reverse osmosis and some carbon block filters reduce PFAS. Look for certification to NSF/ANSI 53 or 58 for PFOA/PFOS.
Filter certified for lead (NSF/ANSI 53 or 58)
$180-$750When lead is a concern, use a filter certified for lead reduction under NSF/ANSI 53 or 58.
Reverse osmosis certified for chromium (NSF/ANSI 58)
$429-$599Chromium-6 needs reverse osmosis for reliable reduction. Standard carbon filters do not address it.
