About this area's water Tuppers Plains/chester Water District
Did you know
- The district's treatment plant is built to strip C-8 (PFOA) and other 'forever chemicals' out of the water along with iron and manganese - an unusual capability for a small rural system, and a legacy of PFAS…
- The source is the Ohio Valley Aquifer, tapped by seven wells at Long Bottom; the treatment plant sits on Sand Hill Cemetery Road, directly across SR 124 from the wellfield.
- Twenty-one storage tanks holding over 3.1 million gallons and more than 600 miles of water line serve roughly 5,700 homes across a hilly, sparsely populated two-county area.
- The board is five directors elected by the district's own customers to three-year terms - the founding trustees are still named in every annual water quality report.
- It keeps emergency interconnects with Leading Creek Conservancy District, the Villages of Racine and Syracuse, and the City of Athens, but reports that on average these connections are not used in a given year.

How the water is treated
Coolville Village buys water that Tuppers Plains/chester Water District treats first, so the steps that count are the seller's. EPA's treatment table registers these steps for Tuppers Plains/chester Water District: chlorine disinfection, iron and manganese removal, fluoridation, granular activated carbon, and ion-exchange softening.
The list is what each system registered with EPA for treatment plants EPA still shows as active, and it can lag a plant upgrade.
Source: EPA Safe Drinking Water Information System (SDWIS) treatment table (EPA Envirofacts, pulled September 2026).
Violations
EPA counts 1 health-based violation for Coolville Village since 2015. Health-based means a contaminant above its legal limit or a required treatment step not carried out. It falls into 1 separate problem (one contaminant or rule in one year); the table lists it.
EPA logs 10 violations of any kind since 2020: 1 for required testing that was missed or reported late; 8 for a report, record or notice that was missing, late or incomplete (the yearly water quality report, a public notice, lead line records); 1 health-based.
| Year | Contaminant or rule | Kind | Measured | Limit | Status in EPA's record |

Lead and copper at the tap
In the sampling period ending December 2024, the 90th-percentile lead result at Coolville Village was 2.8 ppb, under both the current 15 ppb action level and the 10 ppb level that applies from 2027.
EPA has 4 sampling periods on file for Coolville Village since 2016, the first ending in 2017; 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 Coolville Village sent EPA, 224 lines are counted.
| Material | Lines |
|---|---|
| Lead | 0 |
| Galvanized, needing replacement | 0 |
| Unknown material | 224 |
| Not lead | 0 |
| All lines | 224 |
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 Coolville Village buys is treated by Tuppers Plains/chester Water District, so the results below are Tuppers Plains/chester Water District's.
EPA's fifth national round of testing (UCMR 5) took 3 samples of the water entering the pipes of Tuppers Plains/chester Water District in 2025 and measured 29 PFAS. No PFAS was detected, PFOA and PFOS (federal limit 4 ng/L each) among them.
The system reported PFAS treatment: granular activated carbon.
The system reported potential PFAS sources near its supply.
Ohio EPA's own statewide sampling tested 1 plant of Tuppers Plains/chester Water District (latest sample June 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 Tuppers Plains/chester Water District as sampled, most recently July 2025.
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 Coolville Village's samples in 2019, the last year it was sampled, was 26.8 µg/L. The worst yearly average was 26.8 µg/L and the highest single sample was 81.3 µg/L, from 26 samples taken from 2013 to 2019.
For HAA5, the average in the last year sampled was 6.2 µg/L. The worst yearly average was 6.2 µg/L and the highest single sample was 12.8 µg/L, from 26 samples.
| Byproduct | Limit | Latest yearly average | Worst yearly average | Highest sample | Samples |
|---|---|---|---|---|---|
| TTHM | 80 µg/L | 26.8 µg/L (2019) | 26.8 µg/L | 81.3 µg/L | 26 |
| HAA5 | 60 µg/L | 6.2 µg/L | 6.2 µg/L | 12.8 µg/L | 26 |
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 Coolville Village buys is treated by Tuppers Plains/chester Water District, so the results below are Tuppers Plains/chester Water District's.
Nitrate: the highest of 7 samples was 2.3 mg/L (as nitrogen) in 2013; in 2018, the last year sampled, the highest was 1.7 mg/L. No sample was over the limit of 10 mg/L. Nitrate above 10 is unsafe for infants.
Arsenic was not detected in 4 samples (limit 10 µg/L).
| Contaminant | Samples | Highest result | Limit | Samples over limit |
|---|---|---|---|---|
| Nitrate (as nitrogen) | 7 | 2.3 mg/L | 10 mg/L | 0 |
| Arsenic | 4 | 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.

Fluoride
The Ohio Department of Health's report to the CDC (My Water's Fluoride) says Coolville Village buys its water from Tuppers Plains/chester Water District, 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 Tuppers Plains/chester Water District, which treats the water Coolville Village buys.
Measured fluoride: 0.92 mg/L on average leaving the plants of Tuppers Plains/chester Water District, which supplies Coolville Village, in 2018 (in the range dentists aim for); samples ran from 0.92 to 0.97 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.

Lithium
Lithium was not detected in 2 UCMR 5 samples at Tuppers Plains/chester Water District, which supplies Coolville Village, last sampled in 2025 (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.
