AQUA ILLINOIS-VERMILION COUNTY (EPA PWSID IL1835120) delivers surface water to 30,106 residents. This report reflects 29 individual PFAS result(s) from the source UCMR5 observations and the latest Lead & Copper Rule 90th-percentile result. Water hardness and disinfectant type are pending the utility's own annual report.
0health-based violations in the last 10 years
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.
Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
lead 9 µg/L, below the 15 µg/L action level
PFBA 7.3 ng/L detected (no federal or state limit)
Screening tells you if something is worth a closer look; a lab result is the number you can act on.

Lead, read as one of three ranges: 0–4, 5–15 or 15+ ppb
What it can't tell you: It shows a lead range, not an exact level, and tests nothing else unless you pay extra for the optional lab test.
Lab-certified results
ETR Laboratories
50+ substances, including lead, copper, arsenic, nitrate, hardness and coliform bacteria
What it can't tell you: It does not test PFAS, and not every result on the panel falls under the lab's accredited scope.

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Danville, PFBA 7.3 ng/L was detected, with no federal or state limit; the lead 90th-percentile result was 9 µg/L against the 15 µg/L action level. AQUA ILLINOIS-VERMILION COUNTY (PWSID IL1835120) has a Purity Score of 90/100 (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.
AQUA ILLINOIS-VERMILION COUNTY (PWS ID IL1835120) is the public water system on record for Danville, Illinois, serving about 30,106 people. Confirm the utility on your water bill before acting on a specific finding.
Surface water (primary source of record in EPA SDWIS).
Yes. In EPA's UCMR 5 testing (2023-09-18 to 2024-06-19), PFBA was detected at 7.3 ng/L. It has no federal or state limit, so PurityMap shows it without grading it. No PFAS with a limit was detected.
AQUA ILLINOIS-VERMILION COUNTY's most recent lead 90th-percentile result (2026) was 9 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.
PurityMap's current record for Danville holds 31 findings: 1 detected within the reference, 1 detected with no limit 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.
