Screening tells you if something is worth a closer look; a lab result is the number you can act on.

Questions

Frequently asked questions

Is Troy tap water safe to drink?

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Troy, no regulated PFAS were detected in EPA's 2024 testing; the lead 90th-percentile result was 10.6 µg/L against the 15 µg/L action level. TROY CITY PWS (PWSID NY4100050) has a Purity Score of 85/100 (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 Troy?

TROY CITY PWS (PWS ID NY4100050) is the public water system on record for Troy, New York, serving about 51,401 people. Confirm the utility on your water bill before acting on a specific finding.

Where does Troy get its drinking water?

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

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

None of the 29 PFAS in EPA's UCMR 5 testing (2024-05-14 to 2025-02-11) was detected. "Not detected" means below the lab's reporting limit, not proven zero.

Is there lead in Troy's tap water?

TROY CITY PWS's most recent lead 90th-percentile result (2025) was 10.6 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 Troy water report show?

PurityMap's current record for Troy holds 31 findings: 1 detected within the reference and 30 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
