What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 1998 to 2023.

Fluoride, total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate, arsenic and chromium (total): Ohio’s own results, samples taken from July 14, 2020 to July 2, 2025, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal1

Lead

Comes from pipes, often your own

Above the health goal

1.0ppb

90th percentile, 2021 to 2023

In the latest period, 9 in 10 homes sampled were at or below 1.0 ppb, below EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027. EPA’s health goal for lead is zero.

Forms or is added in treatment

Below EPA’s limits

16.5ppb

Highest yearly average, 2020 to 2025

2025, one sample: 6.4 ppb

Averaged by year, the highest was 16.5 ppb, in 2022, below EPA’s legal limit of 80 ppb. In 2025, the latest year on file, its one sample was 6.4 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 20.8 ppb, in 2018.

2025: not found

Averaged by year, the highest was 8.9 ppb, in 2022, below EPA’s legal limit of 60 ppb. In 2025, the latest year on file, it wasn’t found in its one sample. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 8.4 ppb, in 2017.

Nitrate

Highest sample; found in 4 of 6

2025: not found

The highest sample, in 2021, was 0.29 ppm, below EPA’s legal limit of 10 ppm. In 2025, the latest year on file, it wasn’t found in its one sample.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”
2 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Arsenic

What handles it

A certification covers specific claims, not a whole standard. Look for these claims on the certifier’s listing, not the box. Wording varies a little: NSF writes “Lead Reduction,” WQA just “Lead.”

At the tap, or for the whole house?

Lead and copper usually come from pipes and fixtures inside or near your home. A whole-house system sits where water enters, so it cannot catch what your own plumbing adds after it. For those, the filter that counts is the one at the tap. How whole-house systems compare.

What this report can’t tell you

  • Everything else. Fluoride, total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate, arsenic and chromium (total) results here are Ohio’s own from 2020 on, with EPA’s national file for 2012 to 2019. Green Meadows MHP’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.

  • Anything after the latest data. SDWIS data is from 2026 Q3; UCMR 5 didn’t sample this utility; Ohio’s results run from July 14, 2020 to July 2, 2025.

Testing your own tap

Green Meadows MHP’s results are for the water it sends out. What your own service line, solder and fixtures add shows up only in a test of your tap, by a lab Ohio certifies.
