What the records show about Stark County Water District
Who runs it
EPA's record describes Stark County Water District as owned by a local government. It has 2,600 service connections and serves 6,690 people.
EPA classes it as a community water system, one that serves the same residents all year.
Its office telephone on EPA's record is 330-451-2303.

How the water is treated
Stark County Water District buys water that Aqua Ohio - Massillon treats first, so the steps that count are the seller's. EPA's treatment table registers these steps for Aqua Ohio - Massillon: corrosion control, coagulation and settling, chlorine disinfection, fluoridation, lime softening, and sand or media filtration.
Stark County Water District adds nothing of its own on that table.
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 Stark County Water District 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 Stark County Water District 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 4 sampling periods on file for Stark County Water District 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 Stark County Water District sent EPA, 2,724 lines are counted.
| Material | Lines |
|---|---|
| Lead | 0 |
| Galvanized, needing replacement | 0 |
| Unknown material | 0 |
| Not lead | 2,724 |
| All lines | 2,724 |
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
EPA's fifth national round of testing (UCMR 5) took 3 samples of the water entering the pipes of Stark County Water District in 2023 to 2024 and measured 29 PFAS. No PFAS was detected, PFOA and PFOS (federal limit 4 ng/L each) among them.
Ohio EPA's own statewide sampling tested 1 plant of Aqua Ohio - Massillon (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 Aqua Ohio - Massillon as sampled, most recently July 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 Stark County Water District's samples in 2019, the last year it was sampled, was 45.4 µg/L. The worst yearly average was 45.4 µg/L and the highest single sample was 54.1 µg/L, from 16 samples taken from 2012 to 2019.
For HAA5, the average in the last year sampled was 4 µg/L. The worst yearly average was 6.2 µg/L and the highest single sample was 8 µg/L, from 16 samples.
| Byproduct | Limit | Latest yearly average | Worst yearly average | Highest sample | Samples |
|---|---|---|---|---|---|
| TTHM | 80 µg/L | 45.4 µg/L (2019) | 45.4 µg/L | 54.1 µg/L | 16 |
| HAA5 | 60 µg/L | 4 µg/L | 6.2 µg/L | 8 µg/L | 16 |
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 Stark County Water District buys is treated by Aqua Ohio - Massillon, so the results below are Aqua Ohio - Massillon's.
Nitrate was not detected in 9 samples through 2019 (limit 10 mg/L as nitrogen; above 10 is unsafe for infants).
Arsenic: the highest of 5 samples was 2.2 µg/L (limit 10); detections averaged 2.2; none over the limit.
| Contaminant | Samples | Highest result | Limit | Samples over limit |
|---|---|---|---|---|
| Nitrate (as nitrogen) | 9 | not detected | 10 mg/L | 0 |
| Arsenic | 5 | 2.2 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
The water Stark County Water District buys is treated by Aqua Ohio - Massillon, so the results below are Aqua Ohio - Massillon's.
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 4 samples each.
| Compound | Limit | Samples | Detected in | Highest result | Samples over limit |
|---|---|---|---|---|---|
| Benzene | 5 µg/L | 4 | 0 of 4 | not detected | 0 |
| Carbon tetrachloride | 5 µg/L | 4 | 0 of 4 | not detected | 0 |
| 1,2-dichloroethane | 5 µg/L | 4 | 0 of 4 | not detected | 0 |
| Trichloroethylene (TCE) | 5 µg/L | 4 | 0 of 4 | not detected | 0 |
| Tetrachloroethylene (PCE) | 5 µg/L | 4 | 0 of 4 | not detected | 0 |
| Vinyl chloride | 2 µg/L | 4 | 0 of 4 | 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.

Bacteria in the pipes
From 2012 to 2019, 2 of 838 routine total coliform samples taken in the distribution system at Stark County Water District tested positive (0.24%); in 2019, the last year on file, 0 of 108 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 Stark County Water District buys its water from Aqua Ohio - Massillon, 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 Aqua Ohio - Massillon, which treats the water Stark County Water District buys.
Measured fluoride: 0.86 mg/L on average leaving the plants of Aqua Ohio - Massillon, which supplies Stark County Water District, in 2019 (in the range dentists aim for); samples ran from 0.86 to 1.1 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 found in 2 of 2 UCMR 5 samples at Stark County Water District, highest 14.7 µg/L; detections averaged 12.9, last sampled in 2023.
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.
