The short answer

1 result is above EPA’s legal limit, and 2 more are above the health goal. The worst: Haloacetic acids (HAA5), above the legal limit. 62 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2004 to 2025.

Haloacetic acids (HAA5), arsenic, total trihalomethanes (TTHM), 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 Jan. 17, 2012 to Jan. 14, 2019. Newer results are in the utility’s annual water quality report.

Above the legal limit1

Haloacetic acids (HAA5)

Forms or is added in treatment

Above the legal limit

46.3ppb

Highest yearly average, 2020 to 2022

2022 average: 15.8 ppb

Averaged by year, the highest was 46.3 ppb, in 2020, below EPA’s legal limit of 60 ppb. In 2022, the latest year on file, it averaged 15.8 ppb. EPA judges this limit at each sampling point, and recorded a violation for haloacetic acids (HAA5) at this utility in 2026. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 46.7 ppb, in 2019, and EPA recorded a violation in 2018.

Above the health goal2

Arsenic

Comes from the source

Above the health goal

9.6ppb

Highest yearly average, 2020 to 2022

Averaged by year, the highest was 9.6 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 1.9 ppb, in 2018.

What handles it

Comes from the source

Below EPA’s limits

0.5ppm

Highest yearly average, 2022

Averaged by year, the highest was 0.5 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 1.0 ppm, in 2012.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.11ppm

Highest yearly average, 2012 to 2019

2019, one sample: 0.056 ppm

Averaged by year, the highest was 0.11 ppm, in 2016, below EPA’s legal limit of 4.0 ppm. In 2019, the latest year on file, its one sample was 0.056 ppm.

What handles it

2 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Chromium (total)
  • Uranium

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

    For: Arsenic, Lead

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

  • NSF/ANSI 58

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

    For: Arsenic, Lead

    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. Haloacetic acids (HAA5), arsenic, total trihalomethanes (TTHM), 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. Town of Newellton 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 Jan. 17, 2012 to Jan. 14, 2019.

Testing your own tap

Town of Newellton 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 Town of Newellton Water System serves on the state’s list. Some take samples by mail; the state’s page lists them all.
