About this area's water
Did you know
- Ottoville's wastewater plant has been running since 1978 and still discharges to the Little Auglaize River.
- The village was platted twice — an 1845 attempt failed, and the town only took hold after a second platting in 1873.
- The water plant was built in 1982, four years after the wastewater plant, and has had two upgrades since.

Treatment & pressure
How it is treated
Groundwater from 3 wells (#3, #4, #6) is pumped through an aerator, chlorinated, and stored in clear wells, then polished through sand pressure filters before distribution. Plant built 1982 (with two later upgrades), rated 0.325 MGD, averaging about 134,000 gallons/day; two elevated tanks (100,000 gal centrally located, 200,000 gal in the industrial park) provide storage.

Water pressure
Storage is provided by two elevated tanks (100,000 gal and 200,000 gal).
What it costs
$3.40 per 1,000 gallons
Quarterly rate schedule effective 1/1/2024, confirmed directly from the village's Water & Sewer Rate Chart PDF: 3/4"-1" residential service is $36.00/quarter water base + $45.00/quarter sewer base, plus $3.40 per 1,000 gal water and $7.00 per 1,000 gal sewer usage (about $27/mo combined base before usage).

Supply stress
Ohio EPA's source water assessment reportedly rates Ottoville's aquifer as 'high susceptibility to contamination' due to a thin clay layer over the aquifer and nearby contaminant sources; fluoride occurs naturally near (but under) the MCL.

What the records show about Ottoville Village
Who runs it
EPA's record describes Ottoville Village as owned by a local government. It has 485 service connections and serves 976 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 2025. Its office telephone on EPA's record is 419-303-5778.

How the water is treated
EPA's treatment table registers these steps for Ottoville Village: aeration, chlorine disinfection, 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 Ottoville Village since 2015.
EPA logs no violations of any kind for Ottoville Village since 2020.

Lead and copper at the tap
For the sampling period ending December 2025, EPA's record lists the 90th-percentile lead result at Ottoville Village as 0 ppb, under both the current 15 ppb action level and the 10 ppb level that applies from 2027. EPA records a result below the lab's reporting level as 0, so this is the result reported, not proof that no home sampled had lead. The system's own water quality report gives a 90th-percentile result of 4.7 ppb for 2025.
The highest result on file is 6 ppb, in the period ending December 2019.
EPA has 8 sampling periods on file for Ottoville 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 Ottoville Village sent EPA, 485 lines are counted.
| Material | Lines |
|---|---|
| Lead | 0 |
| Galvanized, needing replacement | 0 |
| Unknown material | 372 |
| Not lead | 113 |
| All lines | 485 |
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.

PFAS
Ohio EPA's own statewide sampling tested 1 plant of Ottoville Village (latest sample September 2020). Not one of the six PFAS tested (PFOA, PFOS, PFHxS, PFNA, GenX and PFBS) was detected.
Ohio EPA's current sampling status map lists 1 plant of Ottoville Village as sampled, most recently April 2026.
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 Ottoville Village's samples in 2019, the last year it was sampled, was 50.1 µg/L. The worst yearly average was 66.5 µg/L and the highest single sample was 87.9 µg/L, from 35 samples taken from 2012 to 2019.
For HAA5, the average in the last year sampled was 3.5 µg/L. The worst yearly average was 9.4 µg/L and the highest single sample was 10.7 µg/L, from 35 samples.
| Byproduct | Limit | Latest yearly average | Worst yearly average | Highest sample | Samples |
|---|---|---|---|---|---|
| TTHM | 80 µg/L | 50.1 µg/L (2019) | 66.5 µg/L | 87.9 µg/L | 35 |
| HAA5 | 60 µg/L | 3.5 µg/L | 9.4 µg/L | 10.7 µg/L | 35 |
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 was not detected in 8 samples through 2019 (limit 10 mg/L as nitrogen; above 10 is unsafe for infants).
Arsenic: the highest of 33 samples was 4.6 µg/L (limit 10); detections averaged 3.6; none over the limit.
| Contaminant | Samples | Highest result | Limit | Samples over limit |
|---|---|---|---|---|
| Nitrate (as nitrogen) | 8 | not detected | 10 mg/L | 0 |
| Arsenic | 33 | 4.6 µg/L | 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 3 samples each.
| Compound | Limit | Samples | Detected in | Highest result | Samples over limit |
|---|---|---|---|---|---|
| Benzene | 5 µg/L | 3 | 0 of 3 | not detected | 0 |
| Carbon tetrachloride | 5 µg/L | 3 | 0 of 3 | not detected | 0 |
| 1,2-dichloroethane | 5 µg/L | 3 | 0 of 3 | not detected | 0 |
| Trichloroethylene (TCE) | 5 µg/L | 3 | 0 of 3 | not detected | 0 |
| Tetrachloroethylene (PCE) | 5 µg/L | 3 | 0 of 3 | not detected | 0 |
| Vinyl chloride | 2 µg/L | 3 | 0 of 3 | 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: barium in 3 of 3 samples, highest 17 µg/L (limit 2,000); selenium in 1 of 3 samples, highest 3.92 µg/L (limit 50). Not detected: atrazine in 2 samples, alachlor in 2 samples, chromium in 3 samples, cadmium in 3 samples, mercury in 3 samples, thallium in 3 samples.
| Substance | Kind | Limit | Samples | Detected in | Highest result | Samples over limit |
|---|---|---|---|---|---|---|
| Atrazine | Farm chemical | 3 µg/L | 2 | 0 of 2 | not detected | 0 |
| Alachlor | Farm chemical | 2 µg/L | 2 | 0 of 2 | not detected | 0 |

Bacteria in the pipes
From 2012 to 2019, 0 of 96 routine total coliform samples taken in the distribution system at Ottoville 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 Ottoville Village has fluoride from natural sources at a level higher than what is needed to prevent tooth decay. The level it reports is 1.44 mg/L.
EPA's treatment table lists no fluoridation step at Ottoville Village.
Measured fluoride: 1.45 mg/L on average at the plant's entry points in 2019 (above the 0.7 mg/L level now recommended and well under the 4 mg/L limit); samples ran from 1.42 to 1.51 mg/L across 3 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.
