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 Carmel tap water safe to drink?

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Carmel, no regulated PFAS were detected in EPA's 2024 testing; the lead 90th-percentile result was 2.94 µg/L against the 15 µg/L action level; one health-based violation is on record (E. coli). CARMEL WATER DEPARTMENT (PWSID IN5229004) has a Purity Score of 93/100 (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 Carmel?

CARMEL WATER DEPARTMENT (PWS ID IN5229004) is the public water system on record for Carmel, Indiana, serving about 99,927 people. Confirm the utility on your water bill before acting on a specific finding.

Where does Carmel get its drinking water?

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

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

None of the 29 PFAS in EPA's UCMR 5 testing (2023-02-20 to 2023-11-08) was detected. "Not detected" means below the lab's reporting limit, not proven zero.

Is there lead in Carmel's tap water?

CARMEL WATER DEPARTMENT's most recent lead 90th-percentile result (2021–2023) was 2.94 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.

Has Carmel's water system had violations?

The federal SDWIS record lists a health-based violation for CARMEL WATER DEPARTMENT within about the last ten years: E. coli (2021). The findings above show each one's status.

What does the latest Carmel water report show?

PurityMap's current record for Carmel holds 32 findings: 1 above a reference, 2 detected within the reference and 29 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
