From EPA SDWIS. A clean violation history means no enforcement action was recorded; it does not cover contaminants without a limit.

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 Pontiac tap water safe to drink?
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Pontiac, PFPeA 3.2 ng/L was detected, with no federal or state limit; the lead 90th-percentile result was 2 µg/L against the 15 µg/L action level. IL AMERICAN-PONTIAC (PWSID IL1055030) has a Purity Score of 78/100 (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 Pontiac?
IL AMERICAN-PONTIAC (PWS ID IL1055030) is the public water system on record for Pontiac, Illinois, serving about 11,864 people. Confirm the utility on your water bill before acting on a specific finding.
Where does Pontiac get its drinking water?
Surface water (primary source of record in EPA SDWIS).
Are PFAS "forever chemicals" in Pontiac's water?
Yes. In EPA's UCMR 5 testing (2023-11-01 to 2024-08-07), PFPeA was detected at 3.2 ng/L. It has no federal or state limit, so PurityMap shows it without grading it. No PFAS with a limit was detected.
Is there lead in Pontiac's tap water?
IL AMERICAN-PONTIAC'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 Pontiac water report show?
PurityMap's current record for Pontiac holds 32 findings: 2 above a reference, 1 detected within the reference, 1 detected with no limit and 28 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
