About this area's water
Did you know
- Seville was home to Captain Martin Van Buren Bates - 7 ft 8 in and 470 lb by age 28 - and his wife Anna Swan Bates, 7 ft 11 in and 413 lb at 22. The 'Giants of Seville' settled in the village in 1873, toured Europe…
- Arsenic in Seville's raw groundwater runs close enough to the federal 10 ppb limit (7.99 ppb in 2025) that the sand filtration installed with the 2006 plant is what keeps the village compliant.
- One body, the Seville Board of Public Affairs, runs four utilities: electric, water, sanitary sewer and storm sewer. Its electric side is a non-profit public power system serving more than 2,000 customers, one of about…
- BOPA's website carries a standing correction to Google: it states the Village of Seville has never issued pool credits against sanitary sewer charges for filling a swimming pool.

Treatment & pressure
How it is treated
Groundwater drawn from an aquifer on Eby Road just south of the Medina County line (Wayne County side), via two village wells. The treatment plant has been in operation since May 2006 and uses sand filtration to remove iron and arsenic, water softening, and chlorination. The well field is capable…

EPA compliance record
Lead at the tap: 90th-percentile result 3.2 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
2 violations of any kind logged since 2020: 1 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
Elevated risk at the source. Seville's 2025 CCR states the Eby Road aquifer has a high susceptibility to contamination, due to the sensitive nature of the aquifer in which the well is located and the potential contaminant sources identified - while stressing this does not mean the well field will become contaminated, only that conditions…

How the water is treated
EPA's treatment table registers these steps for Seville Village: aeration, 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 1 health-based violation for Seville 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 2 violations of any kind since 2020: 1 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 2025, the 90th-percentile lead result at Seville Village was 3.2 ppb, under both the current 15 ppb action level and the 10 ppb level that applies from 2027.
EPA has 5 sampling periods on file for Seville 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 Seville Village sent EPA, 1,447 lines are counted.
| Material | Lines |
|---|---|
| Lead | 0 |
| Galvanized, needing replacement | 0 |
| Unknown material | 0 |
| Not lead | 1,447 |
| All lines | 1,447 |
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 Seville Village (latest sample July 2020). Not one of the six PFAS tested (PFOA, PFOS, PFHxS, PFNA, GenX and PFBS) was detected.
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 Seville Village's samples in 2019, the last year it was sampled, was 30.3 µg/L. The worst yearly average was 36.2 µg/L and the highest single sample was 43.4 µg/L, from 15 samples taken from 2012 to 2019.
For HAA5, the average in the last year sampled was 3.5 µg/L. The worst yearly average was 5.9 µg/L and the highest single sample was 7 µg/L, from 15 samples.
| Byproduct | Limit | Latest yearly average | Worst yearly average | Highest sample | Samples |
|---|---|---|---|---|---|
| TTHM | 80 µg/L | 30.3 µg/L (2019) | 36.2 µg/L | 43.4 µg/L | 15 |
| HAA5 | 60 µg/L | 3.5 µg/L | 5.9 µg/L | 7 µg/L | 15 |
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: the highest of 36 samples was 11 µg/L (limit 10); detections averaged 7; 1 over the limit.
| Contaminant | Samples | Highest result | Limit | Samples over limit |
|---|---|---|---|---|
| Nitrate (as nitrogen) | 8 | not detected | 10 mg/L | 0 |
| Arsenic | 36 | 11 µg/L | 10 µg/L | 1 |
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 46 µg/L (limit 2,000). Not detected: atrazine in 2 samples, alachlor in 2 samples, chromium in 3 samples, cadmium in 3 samples, mercury in 3 samples, selenium in 3 samples, thallium in 3 samples.

Bacteria in the pipes
From 2012 to 2019, 2 of 255 routine total coliform samples taken in the distribution system at Seville Village tested positive (0.78%); in 2019, the last year on file, 0 of 24 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 Seville 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 0.36 mg/L.
EPA's treatment table lists no fluoridation step at Seville Village.
Measured fluoride: 0.36 mg/L on average at the plant's entry points in 2018 (below the 0.7 mg/L target); samples ran from 0.35 to 0.36 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.

How well the service area is mapped
EPA estimated the service area of Seville Village with a computer model rather than drawing it from the utility's map, so its edges are approximate.
Counting the people who live in the ZIP codes it overlaps, this atlas estimates 2,455 residents are inside the boundary, 107% of the 2,296 people Seville Village reports serving.
The resident count is an estimate from 2020 Census ZIP-code populations, not a count of customers.
