About this area's water
Did you know
- Chickasaw historically operated four wells (1E, 2W, 3N, 4S by compass direction), but two (1E, 2W) were taken offline in 2019 — the system now runs on just 3N and 4S, matching modern records rather than the four-well…
- Unlike most villages this size, Chickasaw runs real iron/manganese treatment — greensand and pressure-sand filtration, with pre-ozonation used at its since-retired original plant — rather than just chlorinating raw well…
- EPA facility records show both a current and an 'old' Chickasaw Village treatment plant on file, with the old plant, two of the four original wells, and an old storage tank all deactivated together in 2019, evidence of…
- The village adds an orthophosphate corrosion inhibitor to protect pipes and control lead/copper leaching.

How it is treated
EPA treatment records show the active plant (facility 47315) using greensand filtration, pre- and post-hypochlorination, an orthophosphate corrosion inhibitor, and a reaction step for iron/manganese removal and disinfection. A separate, now-deactivated 'old' plant (facility 5585, retired 2019) is…

Supply stress
System now draws on two active wells (3N, 4S) after wells 1E and 2W were deactivated in 2019 (four wells — 1E, 2W, 3N, 4S — were operated historically). Iron/manganese treatment (greensand filtration, ozonation at the retired plant) suggests naturally mineral-rich groundwater typical of Mercer County's glacial aquifers. No drought or…

What the records show about Chickasaw Village
Who runs it
EPA's record describes Chickasaw Village as owned by a local government. It has 182 service connections and serves 358 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 419-925-6709.

How the water is treated
EPA's treatment table registers these steps for Chickasaw Village: corrosion control, chlorine disinfection, and iron and manganese removal.
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 Chickasaw Village since 2015.
EPA logs 1 violation of any kind since 2020: 1 for required testing that was missed or reported late.

Lead and copper at the tap
In the sampling period ending December 2025, the 90th-percentile lead result at Chickasaw 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 10 sampling periods on file for Chickasaw 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 Chickasaw Village sent EPA, 185 lines are counted.
| Material | Lines |
|---|---|
| Lead | 0 |
| Galvanized, needing replacement | 0 |
| Unknown material | 30 |
| Not lead | 155 |
| All lines | 185 |
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 Chickasaw 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 Chickasaw Village as sampled, most recently May 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 Chickasaw Village's samples in 2019, the last year it was sampled, was 0 µg/L. The worst yearly average was 2.6 µg/L and the highest single sample was 2.6 µg/L, from 8 samples taken from 2012 to 2019.
For HAA5, the average in the last year sampled was 0 µg/L. The worst yearly average was 0 µg/L and the highest single sample was 0 µg/L, from 8 samples.
| Byproduct | Limit | Latest yearly average | Worst yearly average | Highest sample | Samples |
|---|---|---|---|---|---|
| TTHM | 80 µg/L | 0 µg/L (2019) | 2.6 µg/L | 2.6 µg/L | 8 |
| HAA5 | 60 µg/L | 0 µg/L | 0 µg/L | 0 µg/L | 8 |
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 9 samples was 0.27 mg/L (as nitrogen) in 2014; in 2019, the last year sampled, the highest was 0.25 mg/L. No sample was over the limit of 10 mg/L. Nitrate above 10 is unsafe for infants.
Arsenic: the highest of 42 samples was 8.7 µg/L (limit 10); detections averaged 4.2; none over the limit.
| Contaminant | Samples | Highest result | Limit | Samples over limit |
|---|---|---|---|---|
| Nitrate (as nitrogen) | 9 | 0.27 mg/L | 10 mg/L | 0 |
| Arsenic | 42 | 8.7 µg/L | 10 µg/L | 0 |
| Combined radium | 1 | 1.6 pCi/L | 5 pCi/L | 0 |
| Gross alpha | 1 | 4.2 pCi/L | 15 pCi/L | 0 |
| Uranium | 1 | not detected | 30 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. Not detected: atrazine in 2 samples, alachlor in 2 samples, chromium in 3 samples, cadmium in 3 samples, barium in 3 samples, mercury in 3 samples, selenium 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 121 routine total coliform samples taken in the distribution system at Chickasaw Village tested positive (0%); in 2019, the last year on file, 0 of 20 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 Chickasaw Village has fluoride from natural sources at a level higher than what is needed to prevent tooth decay. The level it reports is 1.71 mg/L.
EPA's treatment table lists no fluoridation step at Chickasaw Village.
Measured fluoride: 2.05 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 1.69 to 2.05 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.
