Data: U.S. EPA · How we read the data · How we check it
Most of Independence gets its water from Independence Public Water System. Parts of the city are served by a smaller system: Jackson County Public Water Supply District 16 (4,075 people). Your water bill names your system.
Buys water from Kansas City Public Water System. Treated water bought from another system can carry that system's contaminants.
Summary
No federal limits exceeded in EPA data.
- PFAS
- Not detectedNone of 29 PFAS found above EPA's reporting limits in 2 samples (2023–2025).
- Lithium
- Above screening levelHighest result 40.1 ppb. EPA uses 10 ppb to decide what to study further. It is not a health limit, and there is no federal limit for lithium. About 1 in 4 systems tested were above it.
- Lead
- Below action level1.1 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 Apr 2024 to Oct 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 | – |
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
Detected in 2 of 2 samples. Highest result 40.1 ppb. EPA's non-enforceable screening level is 10 ppb. Above screening level The screening level is how EPA decides what to study further, not a health limit. There is no federal limit for lithium and no filter is certified to remove it. About lithium.
Lead and copper
Latest 90th percentile: 1.1 ppb lead (Jan 2023 – Dec 2025). Below action level
Highest since 2016: 9 ppb (Dec 2023).
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2023 – Dec 2025 | 1.1 ppb |
| Jan 2023 – Dec 2023 | 0 ppb |
| Jan 2021 – Dec 2023 | 9 ppb |
Earlier results (9)
| Jul 2022 – Dec 2022 | 1.1 ppb |
| Jan 2022 – Jun 2022 | 1.5 ppb |
| Jan 2018 – Dec 2018 | 6 ppb |
| Jan 2015 – Dec 2017 | 1 ppb |
| Jan 2013 – Dec 2015 | 0.4 ppb |
| Jan 2012 – Dec 2014 | 0.7 ppb |
| Jan 2011 – Dec 2013 | 0 ppb |
| Jan 2010 – Dec 2010 | 0 ppb |
| Jan 2009 – Dec 2009 | 0 ppb |
Copper 90th percentile: 3.3 ppm (Dec 2014), 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
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 | 0.81 ppb | 300 ppb |
| Chromium-6 | 1 ppb | – |
| Strontium | 0.2 ppm | 1.5 ppm |
| Molybdenum | 3.51 ppb | 40 ppb |
| Vanadium | 1.65 ppb | 21 ppb |

For the official word, read the utility's annual Consumer Confidence Report.
Does Independence water have PFAS?
