How the water is treated

EPA's treatment table registers these steps for Oakwood MHP: chlorine disinfection and ion-exchange softening.

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 Oakwood MHP since 2015.

EPA logs no violations of any kind for Oakwood MHP since 2020.

Lead and copper at the tap

In the sampling period ending December 2025, the 90th-percentile lead result at Oakwood MHP 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 6 sampling periods on file for Oakwood MHP 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 Oakwood MHP sent EPA, 94 lines are counted.

Lead0
Galvanized, needing replacement0

All lines94

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 Oakwood MHP (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 Oakwood MHP's samples in 2019, the last year it was sampled, was 16 µg/L. The worst yearly average was 16 µg/L and the highest single sample was 16 µg/L, from 7 samples taken from 2013 to 2019.

For HAA5, the average in the last year sampled was 10.3 µg/L. The worst yearly average was 10.3 µg/L and the highest single sample was 10.3 µg/L, from 7 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 16 samples was 0.32 mg/L (as nitrogen) in 2015; 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 6 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 9 samples each.

"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: barium in 3 of 6 samples, highest 124 µg/L (limit 2,000). Not detected: atrazine, alachlor, chromium, cadmium, mercury, selenium, and thallium, in 6 samples each.

Bacteria in the pipes

From 2012 to 2019, 0 of 101 routine total coliform samples taken in the distribution system at Oakwood MHP tested positive (0%); in 2019, the last year on file, 0 of 15 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 Oakwood MHP has fluoride from natural sources at the recommended level for preventing tooth decay. The level it reports is 1.06 mg/L.

EPA's treatment table lists no fluoridation step at Oakwood MHP.

Measured fluoride: 1.02 mg/L on average at the plant's entry points in 2019 (in the range dentists aim for); samples ran from 1.02 to 1.08 mg/L across 6 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.
