Summary
PFAS above the 2024 federal limits. Systems have until 2029 to meet the PFAS limits.
Is it an emergency? No: PFAS limits are about years of exposure, not a glass of water, and nothing in EPA's data calls for you to stop drinking the water today. If your utility ever issues a boil-water or do-not-drink notice, follow it.
- PFAS
- Above limitPFOA, PFOS above the federal limit in EPA's 2023–2025 testing (PFOA 9.6 ppt vs a limit of 4 ppt, PFOS 16.2 ppt vs a limit of 4 ppt, where ppt = parts per trillion).
- Lead
- Below action level0.4 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 Jan 2026 – now, still in progress (results reported so far). Your home's pipes can make yours higher.
- Violations
- Resolved1 health-based violation since 2016, most recently Apr 2025.
- Pregnant, or mixing baby formula with tap water? Babies drink more water for their size, so PFAS exposure matters more for them. Consider bottled water or a filter certified for PFAS for formula, and ask your doctor. Health effects.
- To lower your PFAS exposure now, a home filter certified for PFAS reduction works (reverse osmosis, or activated carbon certified to NSF/ANSI 53 or 58). Filters for these results.
- Built before 1986, or not sure what your service line is made of? Check your service line and test your tap. Utility data can't show your pipes.
- Tested your own tap? Compare your result with these numbers. Moving? Compare this system with another.
- Read First Utility District of Hardin County'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. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 1 entry point tested Mar 2023 to Jan 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 Above limit Limit 4 ppt | 9.6 ppt 2.4× the limit |
| PFOS Above limit Limit 4 ppt | 16.2 ppt 4.06× the limit |
| PFHxS Detected, below limit Limit 10 ppt | 0.9 ppt 9% of the limit |
| 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 | 0.092 |
| PFBS Detected, below limit Guideline 2,000 ppt | 4.42 ppt |
| PFBA Detected, below limit Guideline 6,000 ppt | 7.58 ppt |
| PFHxA Detected, below limit Guideline 3,000 ppt | 3.3 ppt |
| PFPeA Detected, no limit | 0.78 ppt |
| PFHpA Detected, no limit | 1.05 ppt |
For context: the PFOA average is higher than at 99% of the Tennessee systems EPA tested and the PFOS average is higher than at 98% of the Tennessee systems EPA tested.
29 PFAS tested, 8 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: 0.4 ppb lead (Jan 2026 – now (in progress)). Below action level
Highest since 2016: 9 ppb (Dec 2019).
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2026 – now (in progress) | 0.4 ppb |
| Jan 2023 – Dec 2025 | 0.3 ppb |
| Jan 2020 – Dec 2022 | 0.5 ppb |

| Jan 1993 – Jun 1993 | 3 ppb |
| Jul 1992 – Dec 1992 | 2 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 |
|---|---|
| Apr 2025 | The running annual average for TTHM was above the legal limit. EPA record: TTHM · Maximum Contaminant Level Violation, Average · measured 0.091 mg/l (limit 0.080 mg/L) Resolved |
1 unresolved monitoring or reporting violation: Lead and Copper Rule.
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 |
|---|---|---|
| 1,4-Dioxane | 0.38 ppb | 0.35 ppb |
| Vanadium | 0.41 ppb | 21 ppb |
| Chromium-6 | 0.099 ppb | – |
| Strontium | 0.073 ppm | 1.5 ppm |
| Chlorate | 530 ppb | 210 ppb |
| Manganese | 5.54 ppb | 300 ppb |

Is First Utility District of Hardin County water safe to drink?
First Utility District of Hardin County had 1 health-based violation since 2016, all since resolved. EPA testing found PFAS above the 2024 federal limits, which systems must meet by 2029. 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 First Utility District of Hardin County water have PFAS?

What is the lead level in First Utility District of Hardin County water?
The most recent 90th-percentile lead result for First Utility District of Hardin County is 0.4 ppb, for the monitoring period that began Jan 2026 (still in progress).
