The short answer
Nothing in EPA’s and CDC’s records for this utility is above a health goal. That covers nitrate, arsenic and other regulated chemicals, plus lead and copper, not everything. 6 health-based violations since 2016.
What was found
Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 1.5 ppm, for the period ending Dec. 31, 2019. None since is on file, so it is not counted as a current finding.
Nitrate, haloacetic acids (HAA5) and total trihalomethanes (TTHM): Louisiana’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2020 to 2022, with EPA’s 2012 to 2019 file for earlier years.
Fluoride, chromium (total), arsenic and uranium: EPA’s compliance monitoring file, samples taken from Sept. 24, 2012 to Nov. 28, 2018. Newer results are in the utility’s annual water quality report.
Below EPA’s limits5
Nitrate
Comes from the source
0.7ppm
Highest yearly average, 2022
Averaged by year, the highest was 0.7 ppm, in 2022, below EPA’s legal limit of 10 ppm. That is the only year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 1.2 ppm, in 2018.

Fluoride
Forms or is added in treatment
0.1ppm
Highest yearly average, 2012 to 2018
2018: not found
Averaged by year, the highest was 0.1 ppm, in 2016, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 0.11 ppm. In 2018, the latest year on file, it wasn’t found in any of its two samples.

What this report can’t tell you
Everything else. Nitrate, haloacetic acids (HAA5) and total trihalomethanes (TTHM) results here are Louisiana’s yearly averages as CDC publishes them, from 2020 on, with EPA’s national file for 2012 to 2019. Fluoride, chromium (total), arsenic and uranium come from EPA’s file alone, which ends in 2019. Wheeling Water System Inc’s own annual report, which it must send you every year, has newer results for those and 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; CDC’s yearly averages for Louisiana cover 2020 to 2022; EPA’s compliance samples are from Sept. 24, 2012 to Nov. 28, 2018.
