The short answer
1 result is above EPA’s legal limit, and 2 more are above the health goal. The worst: Total trihalomethanes (TTHM), above the legal limit. 24 health-based violations since 2016.
What handles itWhat was found
Total trihalomethanes (TTHM), arsenic, uranium, 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 and chromium (total): EPA’s compliance monitoring file, samples taken from Feb. 13, 2012 to Feb. 14, 2019. Newer results are in the utility’s annual water quality report.
Above the legal limit1
Total trihalomethanes (TTHM)
Forms or is added in treatment
68.7ppb
Highest yearly average, 2020 to 2022
2022 average: 49.2 ppb
Averaged by year, the highest was 68.7 ppb, in 2021, below EPA’s legal limit of 80 ppb. In 2022, the latest year on file, it averaged 49.2 ppb. EPA judges this limit at each sampling point, and recorded a violation for total trihalomethanes (TTHM) at this utility in 2026. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 93.5 ppb, in 2012, and EPA recorded violations in 2012, 2013, 2014 and 2017.

1.1ppb
Highest yearly average, 2020 to 2022
Averaged by year, the highest was 1.1 ppb, in 2022: below EPA’s legal limit of 10 ppb, but above its health goal of zero. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 6.5 ppb, in 2012.

- Chromium (total)

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, Arsenic (Pentavalent)<=50 ppb Reduction
For: Total trihalomethanes (TTHM), Arsenic
Other certifiers’ wording: VOC Reduction; Arsenic (III) (50 ppb influent level)
- NSF/ANSI 58
Claims: Trihalomethanes (TTHM) Reduction, Arsenic (Pentavalent)<=50 ppb Reduction, Uranium
For: Total trihalomethanes (TTHM), Arsenic, Uranium
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. Total trihalomethanes (TTHM), arsenic, uranium, 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 and chromium (total) come from EPA’s file alone, which ends in 2019. Pointe A la Hache Water System’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 Feb. 13, 2012 to Feb. 14, 2019.
