Nitrate, fluoride, arsenic, chromium (total), haloacetic acids (HAA5) and total trihalomethanes (TTHM): Ohio’s own results, samples taken from June 11, 2020 to Aug. 12, 2025, with EPA’s 2012 to 2019 file for earlier years.

What handles it

4 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Arsenic
  • Chromium (total)
  • Haloacetic acids (HAA5)
  • Total trihalomethanes (TTHM)

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. Nitrate, fluoride, arsenic, chromium (total), haloacetic acids (HAA5) and total trihalomethanes (TTHM) results here are Ohio’s own from 2020 on, with EPA’s national file for 2012 to 2019. Heatherwood Community Water Assoc PWS’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 June 11, 2020 to Aug. 12, 2025.

Testing your own tap

Heatherwood Community Water Assoc PWS’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.
