How the water is treated

EPA's treatment table registers these steps for Cadiz Village: aeration, coagulation and settling, chlorine disinfection, fluoridation, lime softening, powdered activated carbon, 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 8 health-based violations for Cadiz Village since 2015. Health-based means a contaminant above its legal limit or a required treatment step not carried out. They fall into 5 separate problems (one contaminant or rule in one year); the table lists them all.

EPA logs a violation for each compliance period a problem lasts, so the count of 8 includes 3 repeat entries of the problems listed.

EPA logs 13 violations of any kind since 2020: 2 for required testing that was missed or reported late; 4 for a report, record or notice that was missing, late or incomplete (the yearly water quality report, a public notice, lead line records); 7 health-based.

Lead and copper at the tap

In the sampling period ending December 2025, the 90th-percentile lead result at Cadiz 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.

EPA has 4 sampling periods on file for Cadiz 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 Cadiz Village sent EPA, 239 lines are counted.

H2Ohio paid the Rural Community Assistance Partnership to help this small system build its lead service line inventory (Ohio EPA).

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 5 samples of the water entering the pipes of Cadiz Village in 2024 to 2025 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 Cadiz 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 Cadiz Village's samples in 2019, the last year it was sampled, was 49.5 µg/L. The worst yearly average was 64.2 µg/L and the highest single sample was 103 µg/L, from 60 samples taken from 2012 to 2019.

For HAA5, the average in the last year sampled was 25.7 µg/L. The worst yearly average was 43.1 µg/L and the highest single sample was 71.8 µg/L, from 60 samples.

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: the highest of 96 samples was 1.5 mg/L (as nitrogen) in 2015; in 2019, the last year sampled, the highest was 0.69 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).

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 8 samples each.

Farm chemicals and metals

EPA's file holds results for 8 of the nine herbicides and metals it checked. Not detected: atrazine, alachlor, chromium, cadmium, barium, mercury, selenium, and thallium, in 8 samples each.

Bacteria in the pipes

From 2012 to 2019, 1 of 389 routine total coliform samples taken in the distribution system at Cadiz Village tested positive (0.26%); in 2019, the last year on file, 0 of 49 did. E. coli was never found in the 120 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 Cadiz Village adjusts the fluoride level to the recommended level for preventing tooth decay.

EPA's treatment table lists fluoridation among the steps at Cadiz Village.

Measured fluoride: 0.76 mg/L on average at the plant's entry points in 2019 (in the range dentists aim for); samples ran from 0.76 to 1.36 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 Cadiz 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.

Source: EPA UCMR 5 occurrence data (final release, August 2026), samples from 2023 to 2025.

Algal toxins

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 259 times in 484 raw-water samples, across 11 bloom seasons (2016 to 2026); the highest raw-water result was 9.97 µg/L on November 17, 2020. The highest raw-water result since 2024 was 8.98 µg/L.

In treated water, microcystin was detected 1 time; the highest result was 4.04 µg/L (July 2021), above the 1.6 µg/L do-not-drink level.

In all, 989 samples from 2016 to 2026, the latest on August 19, 2026.

Microcystin results
WaterSamplesDetectionsHighest result
Raw water, at the intake4842599.97 µg/L
Treated water50514.04 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.

The sewer bill in the same survey is $1,107 a year at 5,000 gallons a month.

How well the service area is mapped

The service area drawn on the map for Cadiz Village comes from the utility's own map.

Counting the people who live in the ZIP codes it overlaps, this atlas estimates 1,601 residents are inside the boundary, 48% of the 3,353 people Cadiz Village reports serving. With so much of its territory outside the polygon, part of the system shows on the map as private wells.

The resident count is an estimate from 2020 Census ZIP-code populations, not a count of customers.
