The short answer

2 results are above the health goal. The worst: Lead, above the health goal. 3 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2007 to 2023.

Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 2.2 ppm, for the period ending Dec. 31, 2013. None since is on file, so it is not counted as a current finding.

Total trihalomethanes (TTHM), nitrate and haloacetic acids (HAA5): 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 June 25, 2012 to April 25, 2018. Newer results are in the utility’s annual water quality report.

Above the health goal2

Lead

Comes from pipes, often your own

Above the health goal

6.0ppb

90th percentile, 2021 to 2023

In the latest period, 9 in 10 homes sampled were at or below 6.0 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

1.1ppb

Highest yearly average, 2012 to 2018

Averaged by year, the highest was 1.1 ppb, in 2018: below EPA’s legal limit of 10 ppb, but above its health goal of zero. Its highest single sample was 1.3 ppb. That was also the latest year on file.

Below EPA’s limits4

Total trihalomethanes (TTHM)

Below EPA’s limits

3.0ppb

Highest yearly average, 2020 to 2022

Averaged by year, the highest was 3.0 ppb, in 2022, below EPA’s legal limit of 80 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 17.4 ppb, in 2013.

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.13ppm

Highest yearly average, 2012 to 2018

2018 average: 0.075 ppm

Averaged by year, the highest was 0.13 ppm, in 2015, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 0.14 ppm. In 2018, the latest year on file, its three samples averaged 0.075 ppm.

What handles it

Nitrate

Comes from the source

Below EPA’s limits

0.2ppm

Highest yearly average, 2022

Averaged by year, the highest was 0.2 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 0.55 ppm, in 2015.

What handles it

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

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

0.81ppb

Highest yearly average, 2020 to 2022

2022 average: 0.55 ppb

Averaged by year, the highest was 0.81 ppb, in 2020, below EPA’s legal limit of 60 ppb. In 2022, the latest year on file, it averaged 0.55 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 3.4 ppb, in 2018.

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

    For: Lead, Arsenic

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

  • NSF/ANSI 58

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

    For: 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), nitrate and haloacetic acids (HAA5) 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. Village of Dry Prong 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 June 25, 2012 to April 25, 2018.

Testing your own tap

Village of Dry Prong 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.
