Manchester Water Department water quality
Manchester, TN · serves 24,975 people (9,950 connections) · Purchased surface water · Local government · EPA ID TN0000429
Data: U.S. EPA · How we read the data · How we check it
Buys water from Duck River Utility Commission. Treated water bought from another system can carry that system's contaminants.
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 above the federal limit in EPA's 2023–2025 testing (PFOA 4.42 ppt vs a limit of 4 ppt, where ppt = parts per trillion).
- Lead
- Below action level0.6 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
- None health-basedNo health-based violations since 2016.
- 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 Manchester Water Department'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 (931) 728-3991. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 1 entry point tested Apr 2024 to Jan 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 Above limit Limit 4 ppt | 4.42 ppt 1.11× the limit |
| PFOS One sample above limit Limit 4 ppt | 1.65 ppt 41% of the limit |
| 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 | 0.0021 |
| PFBS Detected, below limit Guideline 2,000 ppt | 4.15 ppt |
| PFBA Detected, below limit Guideline 6,000 ppt | 2.85 ppt |
| PFHxA Detected, below limit Guideline 3,000 ppt | 3.1 ppt |
| PFPeA Detected, no limit | 3.52 ppt |
| PFHpA Detected, no limit | 1.05 ppt |
| PFDA Detected, no limit | 0.75 ppt |
For context: the PFOA average is higher than at 95% 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: 0.6 ppb lead (Jan 2026 – now (in progress)). Below action level
Highest since 2016: 15 ppb (Dec 2016).
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2026 – now (in progress) | 0.6 ppb |
| Jan 2023 – Dec 2025 | 0.7 ppb |
| Jan 2020 – Dec 2022 | 1 ppb |

| Jan 1993 – Jun 1993 | 8 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
1 unresolved monitoring or reporting violation: Consumer Confidence 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 |
|---|---|---|
| Manganese | 3.2 ppb | 300 ppb |
| Strontium | 0.045 ppm | 1.5 ppm |
| Vanadium | 0.33 ppb | 21 ppb |
| Chromium-6 | 0.053 ppb | – |
| Chlorate | 80 ppb | 210 ppb |

Questions
Is Manchester Water Department water safe to drink?
Manchester Water Department has no health-based violations since 2016. 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 Manchester Water Department water have PFAS?
Yes. EPA's 2023–2025 testing of Manchester Water Department found 8 PFAS at least once. The highest entry-point averages were above the federal limit for PFOA: PFOA 4.42 ppt (limit 4 ppt for PFOA and PFOS, 10 ppt for the others).
What is the lead level in Manchester Water Department water?
The most recent 90th-percentile lead result for Manchester Water Department is 0.6 ppb, for the monitoring period that began Jan 2026 (still in progress). The federal action level is 15 ppb, falling to 10 ppb in November 2027. The 90th percentile means 9 in 10 homes sampled were at or below this number. Individual homes can be higher.
