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 Pocatello tap water safe to drink?

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Pocatello, no regulated PFAS were detected in EPA's 2024 testing; the lead 90th-percentile result was 5 µg/L against the 15 µg/L action level; one health-based violation is on record (Nitrate). POCATELLO CITY OF (PWSID ID6030043) 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 Pocatello?

POCATELLO CITY OF (PWS ID ID6030043) is the public water system on record for Pocatello, Idaho, serving about 58,231 people. Confirm the utility on your water bill before acting on a specific finding.

Where does Pocatello get its drinking water?

Groundwater (primary source of record in EPA SDWIS).

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

None of the 29 PFAS in EPA's UCMR 5 testing (2024-02-15 to 2024-08-13) was detected. "Not detected" means below the lab's reporting limit, not proven zero.

Is there lead in Pocatello's tap water?

POCATELLO CITY OF'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.

Has Pocatello's water system had violations?

The federal SDWIS record lists a health-based violation for POCATELLO CITY OF within about the last ten years: Nitrate (2021). The findings above show each one's status.

What does the latest Pocatello water report show?

PurityMap's current record for Pocatello holds 32 findings: 2 above a reference, 1 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.
