Questions

Frequently asked questions

Is Myers Corner tap water safe to drink?

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Myers Corner, PFAS were detected below their limits, and PFBA 5.3 ng/L with no federal or state limit; the lead 90th-percentile result was 5 µg/L against the 15 µg/L action level. UNITED WAPPINGER WATER IMPROVEMENT DIST. (PWSID NY1330660) has a Purity Score of 94/100 (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 Myers Corner?

UNITED WAPPINGER WATER IMPROVEMENT DIST. (PWS ID NY1330660) is the public water system on record for Myers Corner, New York, serving about 14,000 people. Confirm the utility on your water bill before acting on a specific finding.

Where does Myers Corner get its drinking water?

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

Are PFAS "forever chemicals" in Myers Corner's water?

In EPA's UCMR 5 testing (2023-04-17 to 2024-03-25), PFBS was detected at 3 ng/L, below the 2,000 ng/L EPA health advisory. PFBA (5.3 ng/L) was also detected; it has no federal or state limit.

Is there lead in Myers Corner's tap water?

UNITED WAPPINGER WATER IMPROVEMENT DIST.'s most recent lead 90th-percentile result (2026) was 5 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 Myers Corner water report show?

PurityMap's current record for Myers Corner holds 31 findings: 1 above a reference, 2 detected within the reference, 1 detected with no limit and 27 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
