The short answer

2 results are above the health goal. The worst: Lead, above the health goal. 21 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 Oct. 1, 2012 to Sept. 17, 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

1.0ppb

90th percentile, 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

0.6ppb

Highest yearly average, 2012 to 2018

2018 average: 0.35 ppb

Averaged by year, the highest was 0.6 ppb, in 2016: below EPA’s legal limit of 10 ppb, but above its health goal of zero. Its highest single sample was 0.71 ppb. In 2018, the latest year on file, its two samples averaged 0.35 ppb.

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 limits3

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

65.2ppb

Highest yearly average, 2020 to 2022

Averaged by year, the highest was 65.2 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 115 ppb, in 2013, and EPA recorded violations in 2014, 2015, 2016, 2017, 2018 and 2019.

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

41.4ppb

Highest yearly average, 2020 to 2022

2022 average: 40.3 ppb

Averaged by year, the highest was 41.4 ppb, in 2021, below EPA’s legal limit of 60 ppb. In 2022, the latest year on file, it averaged 40.3 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 43.4 ppb, in 2019.

What handles it

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.37ppm

Highest yearly average, 2012 to 2018

2018 average: 0.34 ppm

Averaged by year, the highest was 0.37 ppm, in 2015, below EPA’s legal limit of 4.0 ppm. In 2018, the latest year on file, its two samples averaged 0.34 ppm.

What handles it

  • Chromium (total)
  • Nitrate
  • 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: 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), 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. Village of Eros 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 Oct. 1, 2012 to Sept. 17, 2018.

Testing your own tap

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