About this area's water Wauseon City
Did you know
- The raw-water line between Wauseon and Napoleon runs both directions: Wauseon can pull Maumee River water in, or push its own reservoir water back to Napoleon to be treated there when the river is too dirty. It never…
- Wauseon's reservoirs are upground basins, not dammed valleys — a 50-acre one holding 350 million usable gallons and a 15-acre one holding 90 million, filled by pump stations on two farm ditches that drain just 6.6…
- The plant ran 22,069 turbidity samples in 2025. The single cloudiest reading all year was 0.8 NTU, and the worst month still met the standard 99.9996% of the time.
- Wauseon's water is softened the old-fashioned way, with lime and soda ash — a class 3 lime/soda softening plant whose chemical list runs to nine items including potassium permanganate and carbon dioxide.
- The city sells treated water beyond its own limits: it supplies the Village of Lyons, and Fulton County's 100,000-gallon fairgrounds tank is part of the Wauseon system.
History4
- 1989Wauseon's wastewater treatment plant began operations on February 27, 1989, after nearly a decade of preliminary planning.
- 2001In August 2001 Wauseon's reservoir began receiving Maumee River water through a new raw-water line from Napoleon; since then most of the city's drinking water has come from the Maumee rather than…
- 2023Triennial lead and copper distribution sampling: 0 of 20 samples over the action level, with lead at the 90th percentile non-detectable.
- 2025The water plant is operating under a conditional license to operate, placed under Ohio EPA findings and orders for past total trihalomethane (TTHM) violations; the unconditional license returns once…

Supply stress
Quantity risk is real but engineered around. The two upground reservoirs hold about 440 million usable gallons but are fed by only 6.6 square miles of creek runoff, which is precisely why the Napoleon line exists: since August 2001 most of Wauseon's water has come from the Maumee River rather than from Big Ditch and Stuckey Ditch.…

What the records show about Lyons Village
Who runs it
EPA's record describes Lyons Village as owned by a local government. It has 418 service connections and serves 562 people.
EPA classes it as a community water system, one that serves the same residents all year.
Its office telephone on EPA's record is 419-923-2001.

How the water is treated
Lyons Village buys water that Wauseon City treats first, so the steps that count are the seller's. EPA's treatment table registers these steps for Wauseon City: aeration, corrosion control, coagulation and settling, chlorine disinfection, iron and manganese removal, fluoridation, lime softening, powdered activated carbon, and sand or media filtration.
The list is what each system registered with EPA for treatment plants EPA still shows as active, and it can lag a plant upgrade.

Violations
EPA counts 2 health-based violations for Lyons Village since 2015. Health-based means a contaminant above its legal limit or a required treatment step not carried out. They fall into 2 separate problems (one contaminant or rule in one year); the table lists them all.
EPA logs 2 violations of any kind since 2020: 1 for a report, record or notice that was missing, late or incomplete (the yearly water quality report, a public notice, lead line records); 1 health-based.
| Year | Contaminant or rule | Kind | Measured | Limit | Status in EPA's record |
|---|---|---|---|---|---|
| 2024 | Lead and Copper Rule Revisions | lead service line inventory missing or incomplete (a records requirement, not a lead test result) | not on file | not on file | returned to compliance |
| 2017 | Total trihalomethanes (TTHM) | above the legal limit on average | 0.082 mg/L | 0.08 mg/L | returned to compliance |

Lead and copper at the tap
In the sampling period ending December 2025, the 90th-percentile lead result at Lyons Village was 0 ppb, under both the current 15 ppb action level and the 10 ppb level that applies from 2027. A result of 0 means at least nine in ten of the homes sampled had no lead detected.
EPA has 4 sampling periods on file for Lyons Village since 2016, the first ending in 2016; no period was above 10 ppb.
Every water system has to inventory its service lines, the pipes from the main to each building. In the inventory Lyons Village sent EPA, 429 lines are counted.
| Material | Lines |
|---|---|
| Lead | 0 |
| Galvanized, needing replacement | 0 |
| Unknown material | 0 |
| Not lead | 429 |
| All lines | 429 |
Systems sample taps in the homes most likely to have lead pipes or solder. The 90th-percentile result is the level nine in ten of the sampled homes were at or below. Lead comes mostly from service lines and house plumbing, not the source water, so a low result for the system does not clear an old house.
EPA's dashboard status for this inventory: reported all required service line types.

PFAS
The water Lyons Village buys is treated by Wauseon City, so the results below are Wauseon City's.
EPA's fifth national round of testing (UCMR 5) took 4 samples of the water entering the pipes of Wauseon City in 2025 and measured 29 PFAS.
PFOA and PFOS were not detected, against a federal limit of 4 ng/L each.
The highest PFAS results were PFPeA 11 ng/L, PFHxA 9.3 ng/L, and PFBA 8.4 ng/L.
The system reported potential PFAS sources near its supply.
Ohio EPA's own statewide sampling tested 1 plant of Wauseon City (latest sample May 2021). Not one of the six PFAS tested (PFOA, PFOS, PFHxS, PFNA, GenX and PFBS) was detected.
| Compound | Highest result | Federal limit |
|---|---|---|
| PFOA | not detected | 4 ng/L |
| PFOS | not detected | 4 ng/L |
PFAS are the 'forever chemicals' from firefighting foam, plating shops and non-stick coatings. Results are for water leaving the plant, not your tap.

Disinfection byproducts
Chlorine that disinfects water also reacts with organic matter to form byproducts. Two groups have federal limits: total trihalomethanes (TTHM, 80 µg/L) and five haloacetic acids (HAA5, 60 µg/L), judged on running yearly averages at each sampling site.
For TTHM, the average of Lyons Village's samples in 2019, the last year it was sampled, was 46 µg/L. The worst yearly average was 82.7 µg/L and the highest single sample was 159 µg/L, from 56 samples taken from 2012 to 2019. A yearly average over 80 is not itself a violation, because compliance is judged site by site.
For HAA5, the average in the last year sampled was 19.9 µg/L. The worst yearly average was 29.9 µg/L and the highest single sample was 39.5 µg/L, from 56 samples.
| Byproduct | Limit | Latest yearly average | Worst yearly average | Highest sample | Samples |
|---|---|---|---|---|---|
| TTHM | 80 µg/L | 46 µg/L (2019) | 82.7 µg/L | 159 µg/L | 56 |
| HAA5 | 60 µg/L | 19.9 µg/L | 29.9 µg/L | 39.5 µg/L | 56 |
A yearly average of 0 means nothing was detected in that year's samples. EPA's file stops at 2019; Ohio EPA's Drinking Water Watch has newer results.

Nitrate, arsenic and radioactivity
The water Lyons Village buys is treated by Wauseon City, so the results below are Wauseon City's.
Nitrate: the highest of 100 samples was 2.43 mg/L (as nitrogen) in 2013; in 2019, the last year sampled, the highest was 2.25 mg/L. No sample was over the limit of 10 mg/L. Nitrate above 10 is unsafe for infants.
Arsenic was not detected in 8 samples (limit 10 µg/L).
| Contaminant | Samples | Highest result | Limit | Samples over limit |
|---|---|---|---|---|
| Nitrate (as nitrogen) | 100 | 2.43 mg/L | 10 mg/L | 0 |
| Arsenic | 8 | not detected | 10 µg/L | 0 |
Measured in finished water: at the plant's entry points and in the distribution system; raw well and intake samples are left out. Non-detects count as zero.

Solvents and fuels
The water Lyons Village buys is treated by Wauseon City, so the results below are Wauseon City's.
EPA's file holds results for all six solvent and fuel compounds it checked. Benzene, carbon tetrachloride, 1,2-dichloroethane, trichloroethylene, tetrachloroethylene, and vinyl chloride were not detected in 8 samples each.
| Compound | Limit | Samples | Detected in | Highest result | Samples over limit |
|---|---|---|---|---|---|
| Benzene | 5 µg/L | 8 | 0 of 8 | not detected | 0 |
| Carbon tetrachloride | 5 µg/L | 8 | 0 of 8 | not detected | 0 |
| 1,2-dichloroethane | 5 µg/L | 8 | 0 of 8 | not detected | 0 |
| Trichloroethylene (TCE) | 5 µg/L | 8 | 0 of 8 | not detected | 0 |
| Tetrachloroethylene (PCE) | 5 µg/L | 8 | 0 of 8 | not detected | 0 |
| Vinyl chloride | 2 µg/L | 8 | 0 of 8 | not detected | 0 |
"Not detected" means the lab's result was below what its method can measure, not that the compound is absent. Non-detects count as zero in the highest-result column.

Farm chemicals and metals
The water Lyons Village buys is treated by Wauseon City, so the results below are Wauseon City's.
EPA's file holds results for 8 of the nine herbicides and metals it checked. Detected: atrazine in 3 of 24 samples, highest 0.52 µg/L (limit 3); barium in 8 of 8 samples, highest 11 µg/L (limit 2,000). Not detected: alachlor in 24 samples, chromium in 8 samples, cadmium in 8 samples, mercury in 8 samples, selenium in 8 samples, thallium in 8 samples.
| Substance | Kind | Limit | Samples | Detected in | Highest result | Samples over limit |

Bacteria in the pipes
From 2012 to 2019, 0 of 96 routine total coliform samples taken in the distribution system at Lyons Village tested positive (0%); in 2019, the last year on file, 0 of 12 did.
A positive coliform test is a warning sign, not a violation by itself. E. coli is a sign that human or animal waste may have reached the water. Coliform counts are routine samples only; E. coli counts include repeat samples.

Fluoride
The Ohio Department of Health's report to the CDC (My Water's Fluoride) says Lyons Village buys its water from Wauseon City, a system that adjusts the fluoride level to the recommended level for preventing tooth decay.
EPA's treatment table lists fluoridation among the steps at Wauseon City, which treats the water Lyons Village buys.
Measured fluoride: 0.96 mg/L on average leaving the plants of Wauseon City, which supplies Lyons Village, in 2019 (in the range dentists aim for); samples ran from 0.91 to 1.15 mg/L across 8 samples in 2012 to 2019.
The recommended level for preventing tooth decay is 0.7 mg/L; the federal limit is 4 mg/L. The treatment list is what each system registered with EPA and can lag a plant upgrade.

Lithium
Lithium was not detected in 4 UCMR 5 samples at Wauseon City, which supplies Lyons Village, last sampled in 2025 (the method reports from 9 µg/L).
Lithium is not regulated. EPA's draft health reference level is 10 µg/L, and it occurs naturally in deep groundwater, so well systems in the northwest run highest.

Algal toxins
The water Lyons Village buys is treated by Wauseon City, so the results below are Wauseon City's.
Ohio EPA tests for microcystin, a toxin that harmful algal blooms can release, in raw water at the intake and in treated water.
At the intake, microcystin was detected 12 times in 256 raw-water samples, across 3 bloom seasons (2018 to 2022); the highest raw-water result was 8.816 µg/L on June 30, 2020. There has been no raw-water detection since 2024.
Microcystin was never detected in treated water (149 samples).
In all, 405 samples from 2016 to 2026, the latest on August 25, 2026.
| Water | Samples | Detections | Highest result |
|---|---|---|---|
| Raw water, at the intake | 256 | 12 | 8.816 µg/L |
| Treated water | 149 | 0 | not detected |
The ten-day advisory levels for treated water are 0.3 µg/L for children under six and 1.6 µg/L for everyone else. Any detection at the intake triggers more frequent testing until two clean weeks.
