Monroeville Village treats its own water from West Branch Huron River, stored in Monroeville's reservoir.
The system's record
The Ohio Department of Health's fluoridation report (CDC My Water's Fluoride) lists Monroeville Village as buying its water from Sandusky City; EPA's inventory shows its own sources as primary with Sandusky City as an emergency connection. The two records may reflect a blend or a recent switch.

About this area's water
Did you know
- Monroeville stores its river-drawn water in a man-made 'upground reservoir' on Farr Road before treatment rather than pumping straight from the river.
- The village permanently sealed its last combined sewer overflow pipe on November 14, 2025, ending a decades-long federal CSO control obligation.
- It keeps a zero-use emergency backup connection to Northern Ohio Rural Water that delivered no water in 2025 and is used on average 0 days per year.
- The NRHP-listed, 1856-62-built octagonal John Hosford House still stands in this village of about 1,300 residents (2020 census).

What the records show about Monroeville Village
Who runs it
EPA's record describes Monroeville Village as owned by a local government. It has 656 service connections and serves 1,400 people.
EPA classes it as a community water system, one that serves the same residents all year.
EPA's record says it has substantially implemented source water protection under Ohio's program, dating the program from 2023. Its office telephone on EPA's record is 419-465-2922.

How the water is treated
EPA's treatment table registers these steps for Monroeville Village: coagulation and settling, chlorine disinfection, iron and manganese removal, 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's record shows no health-based violations for Monroeville 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 2024, the 90th-percentile lead result at Monroeville 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 3 sampling periods on file for Monroeville 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 Monroeville Village sent EPA, 604 lines are counted.
| Material | Lines |
|---|---|
| Lead | 0 |
| Galvanized, needing replacement | 22 |
| Unknown material | 521 |
| Not lead | 61 |
| All lines | 604 |
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
Ohio EPA's own statewide sampling tested 1 plant of Monroeville Village (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 Monroeville Village's samples in 2019, the last year it was sampled, was 38.3 µg/L. The worst yearly average was 75.5 µg/L and the highest single sample was 109 µg/L, from 57 samples taken from 2012 to 2019.
For HAA5, the average in the last year sampled was 10.9 µg/L. The worst yearly average was 18.1 µg/L and the highest single sample was 27.8 µg/L, from 56 samples.
| Byproduct | Limit | Latest yearly average | Worst yearly average | Highest sample | Samples |
|---|---|---|---|---|---|
| TTHM | 80 µg/L | 38.3 µg/L (2019) | 75.5 µg/L | 109 µg/L | 57 |
| HAA5 | 60 µg/L | 10.9 µg/L | 18.1 µg/L | 27.8 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
Nitrate: the highest of 96 samples was 2.35 mg/L (as nitrogen) in 2013; in 2019, the last year sampled, the highest was 0.65 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 | 2.35 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
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
EPA's file holds results for 8 of the nine herbicides and metals it checked. Detected: atrazine in 1 of 17 samples, highest 1.09 µg/L (limit 3); chromium in 4 of 8 samples, highest 8 µg/L (limit 100); barium in 3 of 8 samples, highest 15 µg/L (limit 2,000). Not detected: alachlor in 17 samples, cadmium in 8 samples, mercury in 8 samples, selenium in 8 samples, thallium in 8 samples.

Bacteria in the pipes
From 2012 to 2019, 0 of 385 routine total coliform samples taken in the distribution system at Monroeville Village tested positive (0%); in 2019, the last year on file, 0 of 48 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 Monroeville Village buys its water from Sandusky City, a system that adjusts the fluoride level to the recommended level for preventing tooth decay.
EPA's treatment table lists no fluoridation step at Monroeville Village.
Measured fluoride: 0.23 mg/L on average at the plant's entry points in 2019 (too little to protect teeth); samples ran from 0.2 to 0.23 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.

Algal toxins
Ohio EPA tests for microcystin, a toxin that harmful algal blooms can release, in raw water at the intake and in treated water.
No microcystin was detected in the 221 raw-water samples.
Microcystin was never detected in treated water (73 samples).
In all, 294 samples from 2016 to 2026, the latest on August 25, 2026.
| Water | Samples | Detections | Highest result |
|---|---|---|---|
| Raw water, at the intake | 221 | 0 | not detected |
| Treated water | 73 | 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.
