Buys water from Hardin County Water District #1, Louisville Water Company. Treated water bought from another system can carry that system's contaminants.
Summary
No federal limits exceeded in EPA data.
- PFAS
- Detected, below limit7 of 29 PFAS found at least once. All averages below the federal limits.
- Lead
- Below action level6 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 2024. Your home's pipes can make yours higher.
- Violations
- None health-basedNo health-based violations since 2016.
- 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.

- Read Hardin County Water District #2'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 (270) 737-1056. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 3 entry points tested Nov 2024 to Aug 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 One sample above limit Limit 4 ppt | 1.55 ppt 39% of the limit |
| PFOS One sample above limit Limit 4 ppt | 1.32 ppt 33% of the limit |
| PFHxS Not detected Limit 10 ppt | – |
| PFNA Detected, below limit Limit 10 ppt | 1.18 ppt 12% of the limit |
| 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 | 0.12 |
| PFBS Detected, below limit Guideline 2,000 ppt | 1.3 ppt |
| PFBA Detected, below limit Guideline 6,000 ppt | 1.3 ppt |
| PFHxA Detected, below limit Guideline 3,000 ppt | 1.32 ppt |
| PFPeA Detected, no limit | 1.85 ppt |
29 PFAS tested, 7 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 12 samples (reporting limit 9 ppb). About lithium.
Lead and copper
Latest 90th percentile: 6 ppb lead (Jan 2022 – Dec 2024). Below action level
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2022 – Dec 2024 | 6 ppb |
| Jan 2019 – Dec 2021 | 2 ppb |
| Jan 2016 – Dec 2018 | 4 ppb |
Earlier results (9)
| Jan 2013 – Dec 2015 | 8 ppb |
| Jan 2010 – Dec 2012 | 3.8 ppb |
| Jan 2007 – Dec 2009 | 12 ppb |
| Jan 2004 – Dec 2006 | 9 ppb |
| Jan 2001 – Dec 2003 | 9.37 ppb |
| Jan 1998 – Dec 2000 | 7 ppb |
| Jan 1997 – Dec 1997 | 7.6 ppb |
| Jan 1996 – Dec 1996 | 10 ppb |
| Jan 1995 – Dec 1995 | 4.4 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 | 2.38 ppb | 300 ppb |
| Molybdenum | 4.3 ppb | 40 ppb |
| Vanadium | 0.6 ppb | 21 ppb |
| Chromium-6 | 0.39 ppb | – |
| Strontium | 0.37 ppm | 1.5 ppm |
| Chlorate | 62 ppb | 210 ppb |

Questions
Is Hardin County Water District #2 water safe to drink?
Hardin County Water District #2 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 Hardin County Water District #2 water have PFAS?
Yes. EPA's 2023–2025 testing of Hardin County Water District #2 found 7 PFAS at least once. None of the averages were above the federal limits.
What is the lead level in Hardin County Water District #2 water?
The most recent 90th-percentile lead result for Hardin County Water District #2 is 6 ppb, for the period ending Dec 2024. The federal action level is 15 ppb, falling to 10 ppb in November 2027.
