About this area's water
Did you know
- Zaleski's water system serves only about 360 people through 175 connections, run out of a village hall reachable by a Gmail address and a single phone line.
- The village draws entirely from three groundwater wells (Wells 6, 8, and 9) with no filtration — just chlorination — before it reaches taps.
- Ohio EPA placed a source water protection designation on the Zaleski well field effective December 3, 2025.

History5
- 2018EPA SDWIS records a violation for an inadequate yearly water quality report (the Consumer Confidence Report), not health-based, opened November 9, 2018; it remains listed as ongoing.
- 2020A second violation for an inadequate yearly water quality report was opened February 6, 2020, per EPA SDWIS, also still listed as ongoing.
- 2023A separate violation for not issuing the yearly water quality report, opened July 1, 2023, was resolved by August 22, 2023.
- 2024A lead service line inventory violation, which EPA counts as health-based though it is a records requirement and not a lead test result, plus a related reporting violation were opened October 17, 2024; EPA shows both returned to compliance August 4, 2025.
- 2025A further violation for not issuing the yearly water quality report was opened July 1, 2025 and remains ongoing. Separately, an Ohio EPA source water protection designation took effect for the Zaleski well field on…

Treatment & pressure
How it is treated
Groundwater from three wells (Wells 6, 8, and 9) is disinfected with post-treatment hypochlorination (chlorination only) before entering the village distribution system; EPA SDWIS's TREATMENT table confirms no filtration or other process is on file for this system.

Water quality & impurities
EPA compliance record
Lead at the tap: 90th-percentile result 0 ppb in 2025 (action level 15 ppb).
EPA health-based violations since 2015:
- 2024Lead and Copper Rule Revisions · lead service line inventory missing or incomplete (a records requirement, not a lead test result) · returned to compliance
5 violations of any kind logged since 2020: 4 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.
Supply stress
A small 3-well groundwater supply for about 360 people through 175 connections in rural Vinton County with one treatment plant and one storage tank — limited redundancy is an inherent vulnerability for a system this size.

How the water is treated
EPA's treatment table registers these steps for Zaleski Village: chlorine disinfection.
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 1 health-based violation for Zaleski 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 5 violations of any kind since 2020: 4 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 |
|---|---|---|---|---|---|
| 2024 | Lead and Copper Rule Revisions | lead service line inventory missing or incomplete (a records requirement, not a lead test result) | not on file | not on file | returned to compliance |

Lead and copper at the tap
In the sampling period ending December 2025, the 90th-percentile lead result at Zaleski 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 4 ppb, in the period ending December 2018.
EPA has 4 sampling periods on file for Zaleski 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 Zaleski Village sent EPA, 171 lines are counted.
| Material | Lines |
|---|---|
| Lead | 0 |
| Galvanized, needing replacement | 0 |
| Unknown material | 0 |
| Not lead | 171 |
| All lines | 171 |
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 Zaleski 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 Zaleski Village as sampled, most recently June 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 Zaleski Village's samples in 2019, the last year it was sampled, was 0 µg/L. The worst yearly average was 11.6 µg/L and the highest single sample was 11.6 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) | 11.6 µg/L | 11.6 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 was not detected in 8 samples through 2019 (limit 10 mg/L as nitrogen; above 10 is unsafe for infants).
Arsenic was not detected in 3 samples (limit 10 µg/L).
| Contaminant | Samples | Highest result | Limit | Samples over limit |
|---|---|---|---|---|
| Nitrate (as nitrogen) | 8 | not detected | 10 mg/L | 0 |
| Arsenic | 3 | 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 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 57 µg/L (limit 2,000). Not detected: atrazine, alachlor, chromium, cadmium, mercury, selenium, and thallium, in 3 samples each.
| Substance | Kind | Limit | Samples | Detected in | Highest result | Samples over limit |
|---|---|---|---|---|---|---|
| Atrazine | Farm chemical | 3 µg/L | 3 | 0 of 3 | not detected | 0 |
| Alachlor | Farm chemical | 2 µg/L | 3 | 0 of 3 | not detected | 0 |

Bacteria in the pipes
From 2012 to 2019, 2 of 102 routine total coliform samples taken in the distribution system at Zaleski Village tested positive (1.96%); in 2019, the last year on file, 0 of 12 did. E. coli was never found in the 2 samples tested for it.
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 Zaleski Village has fluoride from natural sources, but at a level below what is recommended for preventing tooth decay, and does not adjust it. The level it reports is 0.3 mg/L.
EPA's treatment table lists no fluoridation step at Zaleski Village.
Measured fluoride: 0.36 mg/L on average at the plant's entry points in 2019 (below the 0.7 mg/L target); samples ran from 0.33 to 0.43 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.
