Buys water from Eastside Utility District, Tennessee American Water. Treated water bought from another system can carry that system's contaminants.
Summary
No federal limits exceeded in EPA data.
- PFAS
- Detected, below limit2 of 29 PFAS found at least once. All averages below the federal limits.
- Lead
- Below action level2.7 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.

- Read Catoosa Utilities District Authority'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 (706) 937-4121. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 3 entry points 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) Detected, below limit Limit 1 | 0.006 |
| PFBS Detected, below limit Guideline 2,000 ppt | 12 ppt |
| PFBA Detected, below limit Guideline 6,000 ppt | 5.58 ppt |
| PFHxA Not detected Guideline 3,000 ppt | – |
29 PFAS tested, 2 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 10 samples (reporting limit 9 ppb). About lithium.
Lead and copper
Latest 90th percentile: 2.7 ppb lead (Jan 2023 – Dec 2025). Below action level
Highest since 2016: 4.3 ppb (Dec 2019).
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2023 – Dec 2025 | 2.7 ppb |
| Jan 2020 – Dec 2022 | 2.7 ppb |
| Jan 2017 – Dec 2019 | 4.3 ppb |
Earlier results (6)
| Jan 2014 – Dec 2016 | 2.6 ppb |
| Jan 2013 – Dec 2015 | 2.5 ppb |
| Jan 2010 – Dec 2012 | 3.8 ppb |
| Jan 2007 – Dec 2009 | 3.1 ppb |
| Jan 2004 – Dec 2006 | 2.8 ppb |
| Jan 2001 – Dec 2003 | 3.3 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 | 5.56 ppb | 300 ppb |
| Chlorate | 47 ppb | 210 ppb |
| Chromium-6 | 0.25 ppb | – |
| Strontium | 0.033 ppm | 1.5 ppm |
| Vanadium | 0.5 ppb | 21 ppb |

Questions
Is Catoosa Utilities District Authority water safe to drink?
Catoosa Utilities District Authority 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 Catoosa Utilities District Authority water have PFAS?
Yes. EPA's 2023–2025 testing of Catoosa Utilities District Authority found 2 PFAS at least once. None of the averages were above the federal limits.
What is the lead level in Catoosa Utilities District Authority water?
The most recent 90th-percentile lead result for Catoosa Utilities District Authority is 2.7 ppb, for the period ending Dec 2025.
