No result is not a pass. Your utility's annual water quality report may list them, and a certified lab test covers your own tap.

Questions

Frequently asked questions

Is Norristown tap water safe to drink?

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Norristown, PFAS were detected below their limits, and PFBA 7 ng/L and PFPeA 6.9 ng/L with no federal or state limit; the lead 90th-percentile result was 2 µg/L against the 15 µg/L action level. PA AMERICAN NORRISTOWN (PWSID PA1460046) has a Purity Score of 98/100 (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 Norristown?

PA AMERICAN NORRISTOWN (PWS ID PA1460046) is the public water system on record for Norristown, Pennsylvania, serving about 88,885 people. Confirm the utility on your water bill before acting on a specific finding.

Where does Norristown get its drinking water?

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

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

In EPA's UCMR 5 testing (2024-01-04 to 2024-10-09), PFBS was detected at 5.3 ng/L, below the 2,000 ng/L EPA health advisory and PFHxA was detected at 5 ng/L, below the 400,000 ng/L state limit. PFBA (7 ng/L) and PFPeA (6.9 ng/L) were also detected; they have no federal or state limit.

Is there lead in Norristown's tap water?

PA AMERICAN NORRISTOWN's most recent lead 90th-percentile result (2025) was 2 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 Norristown water report show?

PurityMap's current record for Norristown holds 31 findings: 1 above a reference, 3 detected within the reference, 2 detected with no limit and 25 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
