From EPA SDWIS. A clean violation history means no enforcement action was recorded; it does not cover contaminants without a limit.

Questions

Frequently asked questions

Is Ambler tap water safe to drink?

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Ambler, PFOA 15.3 ng/L (limit 4 ng/L), PFOS 13.7 ng/L (limit 4 ng/L) and PFNA 13.5 ng/L (limit 10 ng/L) were measured above their limits in EPA's 2024 testing; the lead 90th-percentile result was 2.3 µg/L against the 15 µg/L action level. AMBLER BORO WATER DEPT (PWSID PA1460020) has a Purity Score of 55/100 (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 Ambler?

AMBLER BORO WATER DEPT (PWS ID PA1460020) is the public water system on record for Ambler, Pennsylvania, serving about 20,000 people. Confirm the utility on your water bill before acting on a specific finding.

Where does Ambler get its drinking water?

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

Are PFAS "forever chemicals" in Ambler's water?

Yes. In EPA's UCMR 5 testing (2024-08-19 to 2025-05-13), PFOA was measured at 15.3 ng/L against a 4 ng/L federal limit, PFOS was measured at 13.7 ng/L against a 4 ng/L federal limit and PFNA was measured at 13.5 ng/L against a 10 ng/L federal limit. PFBS (9.2 ng/L, below the 2,000 ng/L EPA health advisory), PFHxA (12.2 ng/L, below the 400,000 ng/L state limit) and PFHxS (5 ng/L, below the 10 ng/L federal limit) were also detected. 6:2 FTS (6 ng/L), PFBA (10.6 ng/L), PFHpA (9 ng/L) and PFPeA (14 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 Ambler's tap water?

AMBLER BORO WATER DEPT's most recent lead 90th-percentile result (2025) was 2.3 µg/L, below the 15 µg/L action level. That figure comes from sampled homes; lead usually enters from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.

What does the latest Ambler water report show?

PurityMap's current record for Ambler holds 31 findings: 4 above a reference, 4 detected within the reference, 4 detected with no limit and 19 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
