Copper
3.3mg/L
Each block = 1.3 mg/L federal action level
Short answer: Copper (90th percentile) is above its federal limit; everything else measured is within its reference or not detected. Aqua Illinois-Kankakee serves 80,000 residents.

AQUA ILLINOIS-KANKAKEE (EPA PWSID IL0915030) delivers surface water to 80,000 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.
1health-based violation in the last 10 years
From EPA SDWIS. Counted once per contaminant per year, as in the Track record score.
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.
Every filing is listed; the Track record score counts at most one per contaminant per year.

Screening: quick check, not lab-grade
Silver Lake Research
Lead, bacteria, nitrate, copper, iron, chlorine, hardness and pH
What it can't tell you: Each test gives a yes/no or a rough range, not a lab number, and it cannot detect PFAS or arsenic.
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 Kankakee, no regulated PFAS were detected in EPA's 2024 testing; the lead 90th-percentile result was 1.9 µg/L against the 15 µg/L action level. AQUA ILLINOIS-KANKAKEE (PWSID IL0915030) has a Purity Score of 54/100 (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-KANKAKEE (PWS ID IL0915030) is the public water system on record for Kankakee, Illinois, serving about 80,000 people. Confirm the utility on your water bill before acting on a specific finding.
Surface water (primary source of record in EPA SDWIS).
None of the 29 PFAS in EPA's UCMR 5 testing (2024-06-12 to 2025-03-13) was detected. "Not detected" means below the lab's reporting limit, not proven zero.
AQUA ILLINOIS-KANKAKEE's most recent lead 90th-percentile result (2026) was 1.9 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 Kankakee holds 32 findings: 1 above a reference, 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.

Start with the hot-or-cold tap check. Where Aqua Illinois-Kankakee reported something related, it's shown below.
Lead at Aqua Illinois-Kankakee: 1.9 µg/L (90th percentile, 2026 monitoring period (still open)). Lead has no taste, so a taste neither shows nor rules it out.
Copper: 3.3 mg/L (90th percentile, 2017–2019 monitoring period). The federal action level is 1.3 mg/L.
