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. 8 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2004 to 2024.

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.

Arsenic, fluoride, chromium (total) and uranium: EPA’s compliance monitoring file, samples taken from Dec. 2, 2013 to Nov. 5, 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

Above the legal limit

71.1ppb

Highest yearly average, 2020 to 2022

2022 average: 10.6 ppb

Averaged by year, the highest was 71.1 ppb, in 2021, below EPA’s legal limit of 80 ppb. In 2022, the latest year on file, it averaged 10.6 ppb. EPA judges this limit at each sampling point, and recorded a violation for total trihalomethanes (TTHM) at this utility in 2021. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 94.5 ppb, in 2014, and EPA recorded violations in 2015, 2016, 2017 and 2019.

Above the health goal2

Lead

Comes from pipes, often your own

Above the health goal

1.0ppb

90th percentile, 2022 to 2024

In the latest period, 9 in 10 homes sampled were at or below 1.0 ppb, below EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027. EPA’s health goal for lead is zero.

What handles it

Arsenic

Comes from the source

Above the health goal

0.5ppb

Highest yearly average, 2013 to 2019

2019: not found

Averaged by year, the highest was 0.5 ppb, in 2013: below EPA’s legal limit of 10 ppb, but above its health goal of zero. Its highest single sample was 1.0 ppb. In 2019, the latest year on file, it wasn’t found in any of its two samples.

What handles it

  • NSF/ANSI 58 look for “Arsenic (Pentavalent)<=50 ppb Reduction”
  • NSF/ANSI 53 look for “Arsenic (Pentavalent)<=50 ppb Reduction”

Below EPA’s limits2

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

12ppb

Highest yearly average, 2020 to 2022

2022 average: 5.3 ppb

Averaged by year, the highest was 12 ppb, in 2020, below EPA’s legal limit of 60 ppb. In 2022, the latest year on file, it averaged 5.3 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 14.9 ppb, in 2019.

Fluoride

Below EPA’s limits

0.23ppm

Highest yearly average, 2013 to 2019

2019 average: 0.2 ppm

Averaged by year, the highest was 0.23 ppm, in 2016, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 0.25 ppm. In 2019, the latest year on file, its two samples averaged 0.2 ppm.

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, Arsenic (Pentavalent)<=50 ppb Reduction

    For: Total trihalomethanes (TTHM), Lead, Arsenic

    Other certifiers’ wording: VOC Reduction; Arsenic (III) (50 ppb influent level)

  • NSF/ANSI 58

    Claims: Trihalomethanes (TTHM) Reduction, Lead Reduction, Arsenic (Pentavalent)<=50 ppb Reduction

    For: Total trihalomethanes (TTHM), Lead, Arsenic

    Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)

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. Arsenic, fluoride, chromium (total) and uranium come from EPA’s file alone, which ends in 2019. Ward Nine 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 Dec. 2, 2013 to Nov. 5, 2019.

Testing your own tap

Ward Nine 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.

No lab Louisiana certifies is within 75 miles of the area Ward Nine Water System serves on the state’s list. Some take samples by mail; the state’s page lists them all.
