The short answer
2 results are above EPA’s legal limit, and 1 more is above the health goal. The worst: Total trihalomethanes (TTHM), above the legal limit. 56 health-based violations since 2016.
What handles itWhat was found
Lead and copper: EPA SDWIS monitoring periods ending 2007 to 2025.
Total trihalomethanes (TTHM), haloacetic acids (HAA5) and nitrate: 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, arsenic, chromium (total) and uranium: EPA’s compliance monitoring file, samples taken from Dec. 18, 2012 to Sept. 13, 2019. Newer results are in the utility’s annual water quality report.
Above the legal limit2
Total trihalomethanes (TTHM)
Forms or is added in treatment
215ppb
Highest yearly average, 2020 to 2022
2022 average: 207 ppb
Averaged by year, the highest was 215 ppb, in 2020, about 2.7 times EPA’s legal limit of 80 ppb. In 2022, the latest year on file, it averaged 207 ppb, above the limit. EPA recorded violations for total trihalomethanes (TTHM) at this utility in 2020, 2021, 2022, 2023, 2024, 2025 and 2026. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 231 ppb, in 2016, and EPA recorded violations in 2015, 2016, 2017, 2018 and 2019.

Haloacetic acids (HAA5)
Forms or is added in treatment
61ppb
Highest yearly average, 2020 to 2022
Averaged by year, the highest was 61 ppb, in 2022, above EPA’s legal limit of 60 ppb. That was also the latest year on file. EPA recorded violations for haloacetic acids (HAA5) at this utility in 2020 and 2022. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 57.4 ppb, in 2019, and EPA recorded violations in 2018 and 2019.

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
Claims: Trihalomethanes (TTHM) Reduction, Lead Reduction
For: Total trihalomethanes (TTHM), Lead
Other certifiers’ wording: VOC Reduction

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. Total trihalomethanes (TTHM), haloacetic acids (HAA5) and nitrate results here are Louisiana’s yearly averages as CDC publishes them, from 2020 on, with EPA’s national file for 2012 to 2019. Fluoride, arsenic, chromium (total) and uranium come from EPA’s file alone, which ends in 2019. Red Hill Waterworks 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 Dec. 18, 2012 to Sept. 13, 2019.
