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 level1.2 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 Dec 2025. Your home's pipes can make yours higher.
- Violations
- None health-basedNo health-based violations since 2016.

PFAS (“forever chemicals”)
EPA UCMR 5: 1 entry point tested Feb 2024 to Nov 2024. "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 | – |
Michigan has its own PFAS limits. PFNA 6 ppt (this system's highest average: not detected), PFOA 8 ppt (this system's highest average: not detected), PFHxA 400000 ppt (this system's highest average: not detected), PFOS 16 ppt (this system's highest average: not detected), PFHxS 51 ppt (this system's highest average: not detected), PFBS 420 ppt (this system's highest average: not detected), HFPO-DA 370 ppt (this system's highest average: not detected). State compliance is judged on the state's own sampling, so ask the utility or the state program whether it meets them.
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: 1.2 ppb lead (Jan 2025 – Dec 2025). Below action level
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2025 – Dec 2025 | 1.2 ppb |
| Jan 2024 – Dec 2024 | 0.4 ppb |
| Jan 2023 – Dec 2023 | 0 ppb |
Earlier results (9)
| Jan 2022 – Dec 2022 | 0 ppb |
| Jan 2021 – Dec 2021 | 1.15 ppb |
| Jan 2020 – Dec 2020 | 0 ppb |
| Jan 2019 – Dec 2019 | 0.97 ppb |
| Jan 2015 – Dec 2017 | 0 ppb |
| Jan 2012 – Dec 2014 | 0 ppb |
| Jan 2009 – Dec 2011 | 0 ppb |
| Jan 2006 – Dec 2008 | 0 ppb |
| Jan 2003 – Dec 2005 | 0 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
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 |
|---|---|---|
| Chromium-6 | 0.19 ppb | – |
| Strontium | 0.11 ppm | 1.5 ppm |
| Vanadium | 0.68 ppb | 21 ppb |

Questions
Is Clinton Township Water System water safe to drink?
Clinton Township Water System has no health-based violations since 2016. 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 Clinton Township Water System water have PFAS?
EPA tested Clinton Township Water System for 29 PFAS between Feb 2024 and Nov 2024 and none were detected above the reporting limits (about 2 to 20 ppt depending on the chemical).
What is the lead level in Clinton Township Water System water?
The most recent 90th-percentile lead result for Clinton Township Water System is 1.2 ppb, for the period ending Dec 2025. The federal action level is 15 ppb, falling to 10 ppb in November 2027.
