The short answer

2 results are above EPA’s legal limit. The worst: Total trihalomethanes (TTHM), above the legal limit. 2 health-based violations since 2016.

What handles it

What was found

Total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic, nitrate and uranium: 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 Aug. 25, 2015 to July 10, 2018. Newer results are in the utility’s annual water quality report.

Total trihalomethanes (TTHM)

Above the legal limit

22.4ppb

Highest yearly average, 2020 to 2022

2022 average: 15.3 ppb

Averaged by year, the highest was 22.4 ppb, in 2021, below EPA’s legal limit of 80 ppb. In 2022, the latest year on file, it averaged 15.3 ppb. EPA judges this limit at each sampling point, and recorded a violation for total trihalomethanes (TTHM) at this utility in 2024. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 30.3 ppb, in 2013.

Averaged by year, the highest was 10.2 ppb, in 2021, below EPA’s legal limit of 60 ppb. In 2022, the latest year on file, it averaged 5.8 ppb. EPA judges this limit at each sampling point, and recorded a violation for haloacetic acids (HAA5) at this utility in 2024.

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?

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), haloacetic acids (HAA5), arsenic, nitrate and uranium 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. Hagewood 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 Aug. 25, 2015 to July 10, 2018.

Testing your own tap

Hagewood Water System’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 Louisiana certifies.
