Blanchester Village treats its own water from Whitacre Run, Stonelick Creek & West Fork East Fork Little Miami River reservoirs.
The system's record
The Ohio Department of Health's fluoridation report (CDC My Water's Fluoride) lists Blanchester Village as buying its water from Western Water Company; EPA's inventory shows its own sources as primary with Western Water Company as an emergency connection. The two records may reflect a blend or a recent switch.

About this area's water
Did you know
- Blanchester's drinking water comes from three small streams and impoundments — Whitacre Run, Stonelick Creek and the West Fork of the East Fork Little Miami River — rather than one dominant reservoir.
- The village has been treating its own water continuously since 1924.
- Its backup is a chain of other people's water: three emergency taps into the private Western Water Company, which itself draws on wells in the Little Miami River aquifer, Brown County Rural Water from the Ohio River…
- In 2025 the village sampled for 52 different contaminants; most were never detected, and its only violation on federal record dates to October 2017.

History6
- 1832Blanchester laid out by Joseph and John Blancett and named for them.
- 1880-1890The village's largest population increase, 51.3%, during its railroad-era expansion.
- 1924The village began treating its own water — a century of continuous local treatment, still cited in its consumer confidence reports.
- 2017-2018The only violation on the system's federal record: a non-health-based monitoring/reporting violation covering October 2017, returned to compliance on 3 October 2018.

What the records show about Blanchester Village
Who runs it
EPA's record describes Blanchester Village as owned by a local government. It has 1,731 service connections and serves 4,243 people.
EPA classes it as a community water system, one that serves the same residents all year.
EPA's record says it has substantially implemented source water protection under Ohio's program, dating the program from 2023. Its office telephone on EPA's record is 937-783-2621.

How the water is treated
EPA's treatment table registers these steps for Blanchester Village: corrosion control, coagulation and settling, chlorine disinfection, iron and manganese removal, granular 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.

Lead and copper at the tap
In the sampling period ending December 2025, the 90th-percentile lead result at Blanchester Village was 1.2 ppb, under both the current 15 ppb action level and the 10 ppb level that applies from 2027.
EPA has 4 sampling periods on file for Blanchester Village since 2016, the first ending in 2018; 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 Blanchester Village sent EPA, 1,635 lines are counted.
| Material | Lines |
|---|---|
| Lead | 5 |
| Galvanized, needing replacement | 32 |
| Unknown material | 721 |
| Not lead | 877 |
| All lines | 1,635 |
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
EPA's fifth national round of testing (UCMR 5) took 4 samples of the water entering the pipes of Blanchester Village 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 PFBA 9.5 ng/L.
Ohio EPA's own statewide sampling tested 1 plant of Blanchester Village (latest sample June 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 Blanchester Village's samples in 2019, the last year it was sampled, was 44.4 µg/L. The worst yearly average was 76.2 µg/L and the highest single sample was 147 µg/L, from 60 samples taken from 2012 to 2019.
For HAA5, the average in the last year sampled was 20.5 µg/L. The worst yearly average was 49.7 µg/L and the highest single sample was 100 µg/L, from 60 samples.
| Byproduct | Limit | Latest yearly average | Worst yearly average | Highest sample | Samples |
|---|---|---|---|---|---|
| TTHM | 80 µg/L | 44.4 µg/L (2019) | 76.2 µg/L | 147 µg/L | 60 |
| HAA5 | 60 µg/L | 20.5 µg/L | 49.7 µg/L | 100 µg/L | 60 |
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 0.3 mg/L (as nitrogen) in 2018; in 2019, the last year sampled, nitrate was not detected. 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 | 0.3 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 3 of 67 samples, highest 6.7 µg/L (limit 3, 1 over); barium in 8 of 8 samples, highest 44.4 µg/L (limit 2,000). Not detected: alachlor in 68 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 | 67 | 3 of 67 | 6.7 µg/L | 1 |

Bacteria in the pipes
From 2012 to 2019, 1 of 561 routine total coliform samples taken in the distribution system at Blanchester Village tested positive (0.18%); in 2019, the last year on file, 0 of 60 did. E. coli was never found in the 1 sample 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 Blanchester Village buys its water from Western Water Company, a system that adjusts the fluoride level to the recommended level for preventing tooth decay.
EPA's treatment table lists no fluoridation step at Blanchester Village.
Measured fluoride: none was detected in 8 samples at the plant's entry points 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 Blanchester 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
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 1 time in 224 raw-water samples, across 1 bloom season (2026); the highest raw-water result was 0.26 µg/L on July 1, 2026. The highest raw-water result since 2024 was 0.26 µg/L.
Microcystin was never detected in treated water (75 samples).
In all, 299 samples from 2016 to 2026, the latest on August 12, 2026.
| Water | Samples | Detections | Highest result |
|---|---|---|---|
| Raw water, at the intake | 224 | 1 | 0.26 µg/L |
| Treated water | 75 | 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.
