Treatment & pressure
How it is treated
Genoa buys 100% of its finished drinking water from the City of Oregon, which draws Lake Erie surface water from an intake about 1.5 miles offshore of Reno Beach (Anchor Point Marina) and filters and disinfects it — the 2025 CCR reports Oregon turbidity of 0.13 NTU (0.04-0.25) with 100% of samples…

What the records show about Genoa Village
Who runs it
EPA's record describes Genoa Village as owned by a local government. It has 1,440 service connections and serves 3,110 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 419-855-7791.

How the water is treated
Genoa Village buys water that Oregon City treats first, so the steps that count are the seller's. EPA's treatment table registers these steps for Oregon City: corrosion control, coagulation and settling, chlorine disinfection, iron and manganese removal, fluoridation, granular activated carbon, lime softening, ozone, and powdered activated carbon.
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 Genoa 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 11 violations of any kind since 2020: 4 for required testing that was missed or reported late; 6 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 Genoa 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 5 ppb, in the period ending June 2018.
EPA has 10 sampling periods on file for Genoa 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 Genoa Village sent EPA, 1,322 lines are counted.
| Material | Lines |
|---|---|
| Lead | 0 |
| Galvanized, needing replacement | 9 |
| Unknown material | 436 |
| Not lead | 877 |
| All lines | 1,322 |
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.

PFAS
The water Genoa Village buys is treated by Oregon City, so the results below are Oregon City's.
EPA's fifth national round of testing (UCMR 5) took 4 samples of the water entering the pipes of Oregon City in 2023 and measured 29 PFAS.
PFOA and PFOS were not detected, against a federal limit of 4 ng/L each.
The highest PFAS result was PFHxA 3.1 ng/L.
Ohio EPA's own statewide sampling tested 1 plant of Oregon City (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 Oregon City as sampled, most recently October 2023.
| Compound | Highest result | Federal limit |
|---|---|---|
| PFOA | not detected | 4 ng/L |
| PFOS | not detected | 4 ng/L |
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 Genoa Village's samples in 2019, the last year it was sampled, was 37.1 µg/L. The worst yearly average was 63.1 µg/L and the highest single sample was 184 µg/L, from 54 samples taken from 2012 to 2019.
For HAA5, the average in the last year sampled was 9.8 µg/L. The worst yearly average was 15.7 µg/L and the highest single sample was 34.6 µg/L, from 54 samples.
| Byproduct | Limit | Latest yearly average | Worst yearly average | Highest sample | Samples |
|---|---|---|---|---|---|
| TTHM | 80 µg/L | 37.1 µg/L (2019) | 63.1 µg/L | 184 µg/L | 54 |
| HAA5 | 60 µg/L | 9.8 µg/L | 15.7 µg/L | 34.6 µg/L | 54 |
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 Genoa Village buys is treated by Oregon City, so the results below are Oregon City's.
Nitrate: the highest of 96 samples was 5.02 mg/L (as nitrogen) in 2016; in 2019, the last year sampled, the highest was 4.45 mg/L. No sample was over the limit of 10 mg/L. Nitrate above 10 is unsafe for infants.
Arsenic was not detected in 8 samples (limit 10 µg/L).
| Contaminant | Samples | Highest result | Limit | Samples over limit |
|---|---|---|---|---|
| Nitrate (as nitrogen) | 96 | 5.02 mg/L | 10 mg/L | 0 |
| Arsenic | 8 | 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
The water Genoa Village buys is treated by Oregon City, so the results below are Oregon City'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 8 samples each.
| Compound | Limit | Samples | Detected in | Highest result | Samples over limit |
|---|---|---|---|---|---|
| Benzene | 5 µg/L | 8 | 0 of 8 | not detected | 0 |
| Carbon tetrachloride | 5 µg/L | 8 | 0 of 8 | not detected | 0 |
| 1,2-dichloroethane | 5 µg/L | 8 | 0 of 8 | not detected | 0 |
| Trichloroethylene (TCE) | 5 µg/L | 8 | 0 of 8 | not detected | 0 |
| Tetrachloroethylene (PCE) | 5 µg/L | 8 | 0 of 8 | not detected | 0 |
| Vinyl chloride | 2 µg/L | 8 | 0 of 8 | 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
The water Genoa Village buys is treated by Oregon City, so the results below are Oregon City's.
EPA's file holds results for 8 of the nine herbicides and metals it checked. Detected: atrazine in 15 of 38 samples, highest 0.94 µg/L (limit 3); barium in 8 of 8 samples, highest 12 µg/L (limit 2,000). Not detected: alachlor in 38 samples, chromium in 8 samples, cadmium in 8 samples, mercury in 8 samples, selenium in 8 samples, thallium in 8 samples.
| Substance | Kind | Limit | Samples | Detected in | Highest result | Samples over limit |
|---|---|---|---|---|---|---|
| Atrazine | Farm chemical | 3 µg/L | 38 | 15 of 38 | 0.94 µg/L | 0 |

Bacteria in the pipes
From 2012 to 2019, 0 of 294 routine total coliform samples taken in the distribution system at Genoa Village tested positive (0%); in 2019, the last year on file, 0 of 36 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 Genoa Village buys its water from Oregon City, 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 Oregon City, which treats the water Genoa Village buys.
Measured fluoride: 0.86 mg/L on average leaving the plants of Oregon City, which supplies Genoa Village, in 2019 (in the range dentists aim for); samples ran from 0.83 to 1.02 mg/L across 8 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 4 UCMR 5 samples at Oregon City, which supplies Genoa Village, last sampled in 2023 (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.

Algal toxins
The water Genoa Village buys is treated by Oregon City, so the results below are Oregon City's.
Ohio EPA tests for microcystin, a toxin that harmful algal blooms can release, in raw water at the intake and in treated water.
At the intake, microcystin was detected 93 times in 293 raw-water samples, across 11 bloom seasons (2016 to 2026); the highest raw-water result was 25 µg/L on August 30, 2017. The highest raw-water result since 2024 was 5.05 µg/L.
In treated water, microcystin was detected 1 time; the highest result was 0.387 µg/L (July 2026), above the 0.3 µg/L level for children under six.
In all, 502 samples from 2016 to 2026, the latest on August 18, 2026.
| Water | Samples | Detections | Highest result |
|---|---|---|---|
| Raw water, at the intake | 293 | 93 | 25 µg/L |
| Treated water | 209 | 1 | 0.387 µg/L |
The ten-day advisory levels for treated water are 0.3 µg/L for children under six and 1.6 µg/L for everyone else. Any detection at the intake triggers more frequent testing until two clean weeks.

How well the service area is mapped
EPA estimated the service area of Genoa 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 2,296 residents are inside the boundary, 74% of the 3,110 people Genoa Village reports serving.
The resident count is an estimate from 2020 Census ZIP-code populations, not a count of customers.
