About this area's water
Did you know
- Pleasant Hill's wells sit on village-owned land along the Stillwater River and pump at a combined rate of 290 gallons per minute via 30-horsepower submersible pumps.
- The village was originally platted under the name 'Newton' in 1843 even though its post office had used the name Pleasant Hill since 1839.
- Nitrate has been tracked as a contaminant of concern in Pleasant Hill's water since 1992, reaching as high as 7.0 ppm against the 10 ppm federal limit.
- The village uses about 83,500 gallons of water per day for a population of roughly 1,226.
History5

Supply stress
Ohio EPA's 2003 source water assessment rated the aquifer 'high susceptibility to contamination,' based on a relatively thin clay layer covering the aquifer, potential contaminant sources within the protection area, and manmade contaminants (nitrate) detected in treated water since 1992, ranging from below detectable limits up to 7.0 ppm…

Sewers
Sanitary
Water and sewer are billed together on a bi-monthly cycle; the village's Water & Sewer page states the flat capital-charge portion of the bill is '$15 water plus $22 sewer per billing cycle,' with a separate usage-based charge on top.

How the water is treated
EPA's treatment table registers these steps for Pleasant Hill Village: chlorine disinfection.
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 Pleasant Hill Village 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 2025, the 90th-percentile lead result at Pleasant Hill Village was 2.2 ppb, under both the current 15 ppb action level and the 10 ppb level that applies from 2027.
The highest result on file is 5.1 ppb, in the period ending December 2017.
EPA has 9 sampling periods on file for Pleasant Hill 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 Pleasant Hill Village sent EPA, 560 lines are counted.
| Material | Lines |
|---|---|
| Lead | 2 |
| Galvanized, needing replacement | 0 |
| Unknown material | 0 |
| Not lead | 558 |
| All lines | 560 |
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 Pleasant Hill Village (latest sample October 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 Pleasant Hill Village's samples in 2019, the last year it was sampled, was 7.2 µg/L. The worst yearly average was 7.2 µg/L and the highest single sample was 9.2 µg/L, from 16 samples taken from 2012 to 2019.
For HAA5, the average in the last year sampled was 0 µg/L. The worst yearly average was 2.2 µg/L and the highest single sample was 3.1 µg/L, from 16 samples.
| Byproduct | Limit | Latest yearly average | Worst yearly average | Highest sample | Samples |
|---|---|---|---|---|---|
| TTHM | 80 µg/L | 7.2 µg/L (2019) | 7.2 µg/L | 9.2 µg/L | 16 |
| HAA5 | 60 µg/L | 0 µg/L | 2.2 µg/L | 3.1 µg/L | 16 |
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.
Source: EPA Six-Year Review 4 compliance monitoring data, 2012 to 2019, distribution-system samples (non-detects counted as zero).
Nitrate, arsenic and radioactivity
Nitrate: the highest of 13 samples was 8.25 mg/L (as nitrogen) in 2013; in 2019, the last year sampled, the highest was 1.38 mg/L. No sample was over the limit of 10 mg/L. Nitrate above 10 is unsafe for infants.
Arsenic was not detected in 3 samples (limit 10 µg/L).
| Contaminant | Samples | Highest result | Limit | Samples over limit |
|---|---|---|---|---|
| Nitrate (as nitrogen) | 13 | 8.25 mg/L | 10 mg/L | 0 |
| Arsenic | 3 | not detected | 10 µg/L | 0 |
| Combined radium | 1 | not detected | 5 pCi/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 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 all nine herbicides and metals it checked. Detected: cadmium in 1 of 3 samples, highest 0.25 µg/L (limit 5); barium in 3 of 3 samples, highest 145 µg/L (limit 2,000). Not detected: atrazine in 2 samples, alachlor in 2 samples, 2,4-D in 2 samples, chromium in 3 samples, mercury in 3 samples, selenium in 3 samples, thallium in 3 samples.

Bacteria in the pipes
From 2012 to 2019, 0 of 192 routine total coliform samples taken in the distribution system at Pleasant Hill Village tested positive (0%); in 2019, the last year on file, 0 of 24 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 Pleasant Hill 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 0.21 mg/L.
EPA's treatment table lists no fluoridation step at Pleasant Hill Village.
Measured fluoride: none was detected in 3 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.
