Hamler Village

Who runs it

EPA's record describes Hamler Village as owned by a local government. It has 280 service connections and serves 580 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 419-274-7651.

How the water is treated

EPA's treatment table registers these steps for Hamler Village: aeration, corrosion control, chlorine disinfection, ion-exchange softening, 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 24 health-based violations for Hamler Village since 2015. Health-based means a contaminant above its legal limit or a required treatment step not carried out. They fall into 11 separate problems (one contaminant or rule in one year); the table lists the 8 most recent.

EPA logs a violation for each compliance period a problem lasts, so the count of 24 includes 13 repeat entries of the problems listed.

EPA logs 52 violations of any kind since 2020: 26 for required testing that was missed or reported late; 5 for a report, record or notice that was missing, late or incomplete (the yearly water quality report, a public notice, lead line records); 21 health-based.

Lead and copper at the tap

In the sampling period ending December 2025, the 90th-percentile lead result at Hamler 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 2 ppb, in the period ending December 2019.

EPA has 13 sampling periods on file for Hamler 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 Hamler Village sent EPA, 317 lines are counted.

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 Hamler Village (latest sample August 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 Hamler Village as sampled, most recently February 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 Hamler Village's samples in 2019, the last year it was sampled, was 62.7 µg/L. The worst yearly average was 62.7 µg/L and the highest single sample was 108 µg/L, from 51 samples taken from 2012 to 2019.

For HAA5, the average in the last year sampled was 8.1 µg/L. The worst yearly average was 12 µg/L and the highest single sample was 26.9 µg/L, from 51 samples.

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 10 samples was 2.95 mg/L (as nitrogen) in 2013; in 2019, the last year sampled, nitrate was not detected. No sample was over the limit of 10 mg/L. Nitrate above 10 is unsafe for infants.

Arsenic was not detected in 3 samples (limit 10 µg/L).

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. carbon tetrachloride was detected in 1 of 3 samples, highest 0.54 µg/L (limit 5). Benzene, 1,2-dichloroethane, trichloroethylene, tetrachloroethylene, and vinyl chloride were not detected in 3 samples each.

"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 22 µg/L (limit 2,000). Not detected: atrazine, alachlor, chromium, cadmium, mercury, selenium, and thallium, in 3 samples each.

Non-detects count as zero in the highest-result column.

Bacteria in the pipes

From 2012 to 2019, 0 of 185 routine total coliform samples taken in the distribution system at Hamler Village tested positive (0%); in 2019, the last year on file, 0 of 19 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 Hamler Village has fluoride from natural sources at a level higher than what is needed to prevent tooth decay. The level it reports is 2.47 mg/L.

EPA's treatment table lists no fluoridation step at Hamler Village.

Measured fluoride: 2.39 mg/L on average at the plant's entry points in 2018 (high enough that children under 9 can get mottled teeth); samples ran from 2.39 to 2.54 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.

Water and sewer bills

Ohio EPA's 2023 rate survey puts the water bill at Hamler Village for a household using 5,000 gallons a month at $888 a year, about $74 a month.

The sewer bill in the same survey is $924 a year at 5,000 gallons a month.

The survey lists it as “Hamler”. These are inside-city rates and annual bills at the use shown.

How well the service area is mapped

EPA estimated the service area of Hamler Village with a computer model rather than drawing it from the utility's map, so its edges are approximate.
