Summary
No federal limits exceeded in EPA data.
- PFAS
- Not detectedNone of 29 PFAS found above EPA's reporting limits in 4 samples (2023–2025).
- Lead
- Below action level1.9 ppb (parts per billion) at the 90th percentile: 9 in 10 homes sampled were at or below it. Action level 15 ppb, falling to 10 ppb in Nov 2027. Monitoring period ending Jun 2026. Your home's pipes can make yours higher.
- Violations
- Resolved1 health-based violation since 2016, most recently Jan 2024. One required an urgent public notice within 24 hours (the kind behind boil-water notices), most recently Jan 2024. What to do if you get a notice.

- Tested your own tap? Compare your result with these numbers. Moving? Compare this system with another.
- Read Aqua Illinois-Kankakee's annual water quality report (Consumer Confidence Report). It lists every regulated contaminant tested and is usually on the utility's website or mailed with your bill, and you can also request it at (224) 602-6779. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 1 entry point tested Jun 2024 to Mar 2025. "Average" is the highest entry-point average (non-detects counted as zero), the way EPA compares UCMR 5 results to the limits. ppt = parts per trillion. These results do not determine compliance.
| Contaminant | Highest average |
|---|---|
| PFOA Not detected Limit 4 ppt | – |
| PFOS Not detected Limit 4 ppt | – |
| PFHxS Not detected Limit 10 ppt | – |
| PFNA Not detected Limit 10 ppt | – |
| HFPO-DA (GenX) Not detected Limit 10 ppt | – |
| Hazard Index (a combined score for PFHxS, PFNA, GenX and PFBS, where above 1 is over the limit) Not detected Limit 1 | – |
| PFBS Not detected Guideline 2,000 ppt | – |
| PFBA Not detected Guideline 6,000 ppt | – |
| PFHxA Not detected Guideline 3,000 ppt | – |
29 PFAS tested, 0 detected at least once. "Not detected" means below EPA's reporting limit (about 2 to 20 ppt depending on the chemical), not proven zero. PFAS not listed were not detected. The limits for PFHxS, PFNA, GenX and the Hazard Index were proposed for rescission in May 2026. That proposal is not final. Systems have until 2029 to meet the limits.
Lithium
Not detected in 4 samples (reporting limit 9 ppb). About lithium.
Lead and copper
Latest 90th percentile: 1.9 ppb lead (Jan 2026 – Jun 2026). Below action level
Highest since 2016: 131 ppb (Jun 2019).
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2026 – Jun 2026 | 1.9 ppb |
| Jul 2025 – Dec 2025 | 2.4 ppb |
| Jan 2025 – Jun 2025 | 1.8 ppb |
Earlier results (9)
| Jan 2024 – Dec 2024 | 5.8 ppb |
| Jan 2023 – Dec 2023 | 4.2 ppb |
| Jan 2022 – Jun 2022 | 6 ppb |
| Jul 2021 – Dec 2021 | 5.8 ppb |
| Jan 2020 – Dec 2020 | 7.5 ppb |
| Jan 2017 – Dec 2019 | 14 ppb |
| Jan 2019 – Jun 2019 | 131 ppb |
| Jul 2018 – Dec 2018 | 17 ppb |
| Jan 2014 – Dec 2016 | 2 ppb |
Copper 90th percentile: 3.3 ppm (Dec 2019), action level 1,300 ppb.
Lead comes from pipes and fixtures, not the source water, so it varies home to home. The 90th percentile means 9 in 10 sampled homes were at or below it. More on lead.
Violations
| When | What happened |
|---|---|
| Jan 2024 | The water was cloudier than allowed at least once. Cloudiness can shield germs from disinfection. Urgent public notice required What that means EPA record: Interim Enhanced Surface Water Treatment Rule · Single Turbidity Exceed (Enhanced SWTR) (limit ) Resolved |
Health-based violations mean a contaminant exceeded a limit or a required treatment step was missed. Monitoring and reporting violations mean required tests or reports were late or missing, so the water's quality during that time is unknown. The total includes every violation in EPA's records, most of them paperwork.
Earlier EPA testing (2013–2020)
| Contaminant | Highest | Guideline |
|---|---|---|
| Manganese | 0.63 ppb | 300 ppb |
| Molybdenum | 5.5 ppb | 40 ppb |
| Strontium | 0.1 ppm | 1.5 ppm |
| Chromium-6 | 2.4 ppb | – |
| Vanadium | 0.52 ppb | 21 ppb |
| 1,4-Dioxane | 0.59 ppb | 0.35 ppb |

Questions
Is Aqua Illinois-Kankakee water safe to drink?
Aqua Illinois-Kankakee had 1 health-based violation since 2016, all since resolved. EPA testing found no PFAS above the federal limits. Federal data can't tell you about your own pipes: lead comes from service lines and plumbing, so test your tap if your home was built before 1986. For the official word, read the utility's annual Consumer Confidence Report.
Does Aqua Illinois-Kankakee water have PFAS?
EPA tested Aqua Illinois-Kankakee for 29 PFAS between Jun 2024 and Mar 2025 and none were detected above the reporting limits (about 2 to 20 ppt depending on the chemical).
What is the lead level in Aqua Illinois-Kankakee water?
The most recent 90th-percentile lead result for Aqua Illinois-Kankakee is 1.9 ppb, for the period ending Jun 2026. The federal action level is 15 ppb, falling to 10 ppb in November 2027. The 90th percentile means 9 in 10 homes sampled were at or below this number. Individual homes can be higher.
