The ZIP code it serves
The short answer
1 result is above the limit’s level with no violation recorded. The worst: Haloacetic acids (HAA5), above the limit’s level, no violation. 1 health-based violation since 2016.
What was found
Haloacetic acids (HAA5), nitrate, total trihalomethanes (TTHM), fluoride, arsenic and chromium (total): Ohio’s own results, samples taken from Jan. 6, 2020 to Oct. 12, 2025, with EPA’s 2012 to 2019 file for earlier years.
Above the limit’s level, no violation recorded1
Haloacetic acids (HAA5)
Forms or is added in treatment
79.4ppb
Highest yearly average, 2020 to 2025
2025 average: 6.5 ppb
Averaged by year, the highest was 79.4 ppb, in 2021, above EPA’s legal limit of 60 ppb. In 2025, the latest year on file, its four samples averaged 6.5 ppb. EPA judges this limit on running averages at each sampling point, and recorded no violation for haloacetic acids (HAA5) at this utility since 2020. Results like these with no violation often include water sampled before treatment or blending; the utility’s annual report says what reaches the tap. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 32.5 ppb, in 2015.

What this report can’t tell you
Everything else. Haloacetic acids (HAA5), nitrate, total trihalomethanes (TTHM), fluoride, arsenic and chromium (total) results here are Ohio’s own from 2020 on, with EPA’s national file for 2012 to 2019. Dfc Mobile Home Park’s own annual report, which it must send you every year, has the contaminants this page does not show.
Your own plumbing. Lead results are the 90th percentile across homes the utility samples. Your home’s service line, solder and fixtures decide yours. A certified lab test is the only way to know.
What it means for your health. This page reports what the records show and EPA’s limits and goals; it is not medical advice. If you are worried about a health effect, talk to a doctor or your local health department.
