About this area's water
Did you know
- Clyde's first water works (1883-86) drew on what is now the town's community park pond, along with artesian wells — the whole system, including 18,215 feet of main and 38 hydrants, cost $33,092.95.
- The 2.4 MGD plant Clyde still uses exists because a Citizens Water Committee, on May 18, 1992, talked the city council out of a larger proposal and into hiring a new engineering firm to design a smaller, cheaper plant.
- A water tower was built at Woodland Avenue in 2001 in conjunction with the Whirlpool plant in Clyde.
- Before 1885 Clyde fought fires with cisterns built into the streets and filled by surface drainage.

History6
- pre-1885Clyde had no reliable water supply; fire cisterns built at intervals in the streets and filled from surface drainage were depended on for fighting fires.
- 1883-86First public supply works developed, using what is now the community park pond, artesian wells, and 18,215 feet of main pipe with 38 fire hydrants. Total project cost $33,092.95.
- 1939Existing 250,000-gallon clearwell constructed between the pond and the water works drive.
- 1949-50Existing treatment plant and Raccoon Creek Reservoir constructed at a total project cost of $800,000.
- 1970-71Major water system improvements: Beaver Creek Reservoir, Beaver Creek pump house, raw water pipeline, Meadow Lane water tank, and rehabilitation of the treatment plant.
- 1973New fluoridation equipment installed.

What the records show about Clyde City
Who runs it
EPA's record describes Clyde City as owned by a local government. It has 2,890 service connections and serves 6,325 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 419-547-9805.

How the water is treated
EPA's treatment table registers these steps for Clyde City: corrosion control, coagulation and settling, chlorine disinfection, iron and manganese removal, 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's record shows no health-based violations for Clyde City since 2015.
EPA logs 1 violation 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).

Lead and copper at the tap
In the sampling period ending December 2023, the 90th-percentile lead result at Clyde City 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 3 sampling periods on file for Clyde City 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 Clyde City sent EPA, 2,918 lines are counted.
| Material | Lines |
|---|---|
| Lead | 0 |
| Galvanized, needing replacement | 0 |
| Unknown material | 0 |
| Not lead | 2,918 |
| All lines | 2,918 |
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 4 samples of the water entering the pipes of Clyde City in 2025 and measured 29 PFAS.
PFOA and PFOS were not detected, against a federal limit of 4 ng/L each.
The highest PFAS result was PFBA 6.6 ng/L.
Ohio EPA's own statewide sampling tested 1 plant of Clyde City (latest sample September 2020). Not one of the six PFAS tested (PFOA, PFOS, PFHxS, PFNA, GenX and PFBS) was detected.
| 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 Clyde City's samples in 2019, the last year it was sampled, was 51.2 µg/L. The worst yearly average was 55 µg/L and the highest single sample was 92.7 µg/L, from 65 samples taken from 2012 to 2019.
For HAA5, the average in the last year sampled was 23.6 µg/L. The worst yearly average was 27.2 µg/L and the highest single sample was 39 µg/L, from 69 samples.
| Byproduct | Limit | Latest yearly average | Worst yearly average | Highest sample | Samples |
|---|---|---|---|---|---|
| TTHM | 80 µg/L | 51.2 µg/L (2019) | 55 µg/L | 92.7 µg/L | 65 |
| HAA5 | 60 µg/L | 23.6 µg/L | 27.2 µg/L | 39 µg/L | 69 |
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 95 samples was 0.83 mg/L (as nitrogen), in 2019, the last year sampled. 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) | 95 | 0.83 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
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
EPA's file holds results for 8 of the nine herbicides and metals it checked. Detected: atrazine in 20 of 24 samples, highest 0.64 µg/L (limit 3). Not detected: alachlor in 23 samples, chromium in 8 samples, cadmium in 8 samples, barium 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 | 24 | 20 of 24 | 0.64 µg/L | 0 |

Bacteria in the pipes
From 2012 to 2019, 0 of 770 routine total coliform samples taken in the distribution system at Clyde City tested positive (0%); in 2019, the last year on file, 0 of 98 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 Clyde City adjusts the fluoride level to the recommended level for preventing tooth decay.
EPA's treatment table lists fluoridation among the steps at Clyde City.
Measured fluoride: 0.98 mg/L on average at the plant's entry points in 2019 (in the range dentists aim for); samples ran from 0.82 to 1.07 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 Clyde City, 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.

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 2 times in 216 raw-water samples, across 2 bloom seasons (2023 to 2026); the highest raw-water result was 0.649 µg/L on October 24, 2023. The highest raw-water result since 2024 was 0.56 µg/L.
Microcystin was never detected in treated water (83 samples).
In all, 299 samples from 2016 to 2026, the latest on August 25, 2026.
| Water | Samples | Detections | Highest result |
|---|---|---|---|
| Raw water, at the intake | 216 | 2 | 0.649 µg/L |
| Treated water | 83 | 0 | not detected |
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 Clyde City 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 6,314 residents are inside the boundary, 100% of the 6,325 people Clyde City reports serving.
The resident count is an estimate from 2020 Census ZIP-code populations, not a count of customers.
