What handles itWhat was found
Arsenic, total trihalomethanes (TTHM), fluoride, haloacetic acids (HAA5), nitrate and chromium (total): Ohio’s own results, samples taken from Jan. 2, 2020 to Oct. 7, 2025, with EPA’s 2012 to 2019 file for earlier years.
Above the health goal1
Arsenic
Comes from the source
1.6ppb
Highest yearly average, 2020 to 2025
2025: not found
Averaged by year, the highest was 1.6 ppb, in 2021: below EPA’s legal limit of 10 ppb, but above its health goal of zero. Its highest single sample was 5.0 ppb. In 2025, the latest year on file, it wasn’t found in any of its four samples. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 4.1 ppb, in 2019.

- 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.
- Chromium (total)
- Lead
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.”
- NSF/ANSI 53
Claim: Arsenic (Pentavalent)<=50 ppb Reduction
For: Arsenic
Other certifiers’ wording: Arsenic (III) (50 ppb influent level)
- NSF/ANSI 58
Claim: Arsenic (Pentavalent)<=50 ppb Reduction
For: Arsenic
Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)
At the tap, or for the whole house?
These come with the water itself, so a whole-house system certified for the same claims treats every tap and shower. A filter at the tap treats drinking water for much less. How whole-house systems compare.

What this report can’t tell you
Everything else. Arsenic, total trihalomethanes (TTHM), fluoride, haloacetic acids (HAA5), nitrate and chromium (total) results here are Ohio’s own from 2020 on, with EPA’s national file for 2012 to 2019. Loudonville Village’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 Jan. 2, 2020 to Oct. 7, 2025.
