About this area's water
Did you know
- Plymouth village straddles the Richland/Huron county line so directly that police jurisdiction is split between the two counties' sheriff's departments.
- The village operates no water treatment plant of its own; it is entirely a wholesale customer of the City of Willard, whose plant draws from a 215-acre, 2.3-billion-gallon upground reservoir on the West Branch Huron…

Treatment & pressure
How it is treated
Plymouth Village buys 100% of its finished drinking water wholesale from the City of Willard and treats none of its own. Willard's plant is a Class III surface-water facility (design capacity 3.2 MGD, currently treating roughly 1.3 MGD average) drawing raw water from the West Branch Huron River…

Supply stress
Plymouth has no independent water source and depends entirely on Willard's West Branch Huron River reservoir and treatment plant as its sole wholesale supplier, so any Willard supply, drought, or treatment disruption directly affects Plymouth. EPA also lists three open violations for an inadequate yearly water quality report (the Consumer Confidence Report), dated 2019 and 2020.

What the records show about Plymouth Village
Who runs it
EPA's record describes Plymouth Village as owned by a local government. It has 838 service connections and serves 1,874 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 419-687-4331.

How the water is treated
Plymouth Village buys water that Willard City treats first, so the steps that count are the seller's. EPA's treatment table registers these steps for Willard City: corrosion control, coagulation and settling, chlorine disinfection, iron and manganese removal, fluoridation, powdered activated carbon, and sand or media filtration.
Plymouth Village adds nothing of its own on that table.
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's record shows no health-based violations for Plymouth Village since 2015.
EPA logs 1 violation 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).

Lead and copper at the tap
In the sampling period ending December 2025, the 90th-percentile lead result at Plymouth 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.
The highest result on file is 9.8 ppb, in the period ending December 2022.
EPA has 6 sampling periods on file for Plymouth Village since 2016, the first ending in 2018; 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 Plymouth Village sent EPA, 771 lines are counted.
| Material | Lines |
|---|---|
| Lead | 5 |
| Galvanized, needing replacement | 1 |
| Unknown material | 673 |
| Not lead | 92 |
| All lines | 771 |
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 Plymouth Village buys is treated by Willard City, so the results below are Willard City's.
EPA's fifth national round of testing (UCMR 5) took 6 samples of the water entering the pipes of Willard City in 2023 and measured 29 PFAS. No PFAS was detected, PFOA and PFOS (federal limit 4 ng/L each) among them.
Ohio EPA's own statewide sampling tested 1 plant of Willard City (latest sample September 2020). Not one of the six PFAS tested (PFOA, PFOS, PFHxS, PFNA, GenX and PFBS) was detected.
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 Plymouth Village's samples in 2019, the last year it was sampled, was 45.8 µg/L. The worst yearly average was 60.9 µg/L and the highest single sample was 84.2 µg/L, from 60 samples taken from 2012 to 2019.
For HAA5, the average in the last year sampled was 21.7 µg/L. The worst yearly average was 34.8 µg/L and the highest single sample was 49.9 µg/L, from 60 samples.
| Byproduct | Limit | Latest yearly average | Worst yearly average | Highest sample | Samples |
|---|---|---|---|---|---|
| TTHM | 80 µg/L | 45.8 µg/L (2019) | 60.9 µg/L | 84.2 µg/L | 60 |
| HAA5 | 60 µg/L | 21.7 µg/L | 34.8 µg/L | 49.9 µg/L | 60 |
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 Plymouth Village buys is treated by Willard City, so the results below are Willard City's.
Nitrate: the highest of 96 samples was 1.21 mg/L (as nitrogen) in 2016; in 2019, the last year sampled, the highest was 1.05 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) | 96 | 1.21 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 Plymouth Village buys is treated by Willard City, so the results below are Willard 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 Plymouth Village buys is treated by Willard City, so the results below are Willard City's.
EPA's file holds results for 8 of the nine herbicides and metals it checked. Detected: barium in 8 of 8 samples, highest 34 µg/L (limit 2,000). Not detected: atrazine, alachlor, chromium, cadmium, mercury, selenium, and thallium, in 8 samples each.
| Substance | Kind | Limit | Samples | Detected in | Highest result | Samples over limit |
|---|---|---|---|---|---|---|
| Atrazine | Farm chemical | 3 µg/L | 8 | 0 of 8 | not detected | 0 |
| Alachlor | Farm chemical | 2 µg/L | 8 | 0 of 8 | not detected | 0 |
| Chromium | Metal | 100 µg/L | 8 | 0 of 8 | not detected | 0 |
| Cadmium | Metal | 5 µg/L | 8 | 0 of 8 | not detected | 0 |

Bacteria in the pipes
From 2012 to 2019, 1 of 195 routine total coliform samples taken in the distribution system at Plymouth Village tested positive (0.51%); in 2019, the last year on file, 0 of 24 did. E. coli was never found in the 1 sample tested for it.
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 Plymouth Village buys its water from Willard 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 Willard City, which treats the water Plymouth Village buys.
Measured fluoride: 0.86 mg/L on average leaving the plants of Willard City, which supplies Plymouth Village, in 2019 (in the range dentists aim for); samples ran from 0.75 to 0.94 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 Willard City, which supplies Plymouth Village, last sampled in 2023 (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 Plymouth Village buys is treated by Willard City, so the results below are Willard 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 28 times in 245 raw-water samples, across 2 bloom seasons (2017 to 2024); the highest raw-water result was 5 µg/L on November 8, 2017. The highest raw-water result since 2024 was 0.564 µg/L.
Microcystin was never detected in treated water (109 samples).
In all, 354 samples from 2016 to 2026, the latest on August 24, 2026.
| Water | Samples | Detections | Highest result |
|---|---|---|---|
| Raw water, at the intake | 245 | 28 | 5 µg/L |
| Treated water | 109 | 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.
