Is Drexel Hill Tap Water Safe? 2026 Water Quality Report

Short answer: Three PFAS, PFNA, PFOA and PFOS, are above their federal limits (2024 limits that water systems have until at least 2029 to meet); lithium sits above a screening level, and a past health-based violation (E. coli) is on record. Aqua Pa Main System serves 822,600 residents.

Questions

Frequently asked questions

Is Drexel Hill tap water safe to drink?

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Drexel Hill, PFOA 12.6 ng/L (limit 4 ng/L), PFOS 9.2 ng/L (limit 4 ng/L) and PFNA 12 ng/L (limit 10 ng/L) were measured above their limits in EPA's 2024 testing; one health-based violation is on record (E. coli). AQUA PA MAIN SYSTEM (PWSID PA1460073) has a Purity Score of 53/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured. Water can change in your own pipes, so a certified test is the only way to know what comes out of your tap.

Who provides tap water in Drexel Hill?

AQUA PA MAIN SYSTEM (PWS ID PA1460073) is the public water system on record for Drexel Hill, Pennsylvania, serving about 822,600 people. Confirm the utility on your water bill before acting on a specific finding.

Where does Drexel Hill get its drinking water?

Surface water (primary source of record in EPA SDWIS).

Are PFAS "forever chemicals" in Drexel Hill's water?

Yes. In EPA's UCMR 5 testing (2024-02-01 to 2024-12-11), PFOA was measured at 12.6 ng/L against a 4 ng/L federal limit, PFOS was measured at 9.2 ng/L against a 4 ng/L federal limit and PFNA was measured at 12 ng/L against a 10 ng/L federal limit. PFBS (9.5 ng/L, below the 2,000 ng/L EPA health advisory), PFHxA (17.2 ng/L, below the 400,000 ng/L state limit) and PFHxS (7.7 ng/L, below the 10 ng/L federal limit) were also detected. PFBA (10.1 ng/L), PFHpA (6.9 ng/L) and PFPeA (21.8 ng/L) were also detected; they have no federal or state limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap.

Is there lead in Drexel Hill's tap water?

Lead is not in Drexel Hill's current published record. Lead usually enters from a building's own pipes and fixtures, so a certified home test is the way to know yours.

Has Drexel Hill's water system had violations?

The federal SDWIS record lists a health-based violation for AQUA PA MAIN SYSTEM within about the last ten years: E. coli (2017). The findings above show each one's status.

What does the latest Drexel Hill water report show?

PurityMap's current record for Drexel Hill holds 32 findings: 5 above a reference, 3 detected within the reference, 3 detected with no limit and 21 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
