The short answer

2 results are above the health goal. The worst: Lead, above the health goal. 1 health-based violation since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 1994 to 2025.

Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 2.0 ppm, for the period ending Dec. 31, 1999. None since is on file, so it is not counted as a current finding.

Total trihalomethanes (TTHM), haloacetic acids (HAA5) and nitrate: Indiana’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2022 to 2023, with EPA’s 2012 to 2019 file for earlier years.

Arsenic, fluoride, chromium (total) and uranium: EPA’s compliance monitoring file, samples taken from July 11, 2012 to July 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

2.0ppb

90th percentile, 2023 to 2025

In the latest period, 9 in 10 homes sampled were at or below 2.0 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

0.7ppb

Highest yearly average, 2012 to 2018

2018, one sample: 0.7 ppb

Averaged by year, the highest was 0.7 ppb, in 2012: below EPA’s legal limit of 10 ppb, but above its health goal of zero. In 2018, the latest year on file, its one sample was 0.7 ppb.

What handles it

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

Below EPA’s limits

47ppb

Highest yearly average, 2022 to 2023

Averaged by year, the highest was 47 ppb, in 2023, 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 47 ppb, in 2018.

2023 average: 20 ppb

Averaged by year, the highest was 25 ppb, in 2022, below EPA’s legal limit of 60 ppb. In 2023, the latest year on file, it averaged 20 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 23 ppb, in 2016.

Highest yearly average, 2022 to 2023

Averaged by year, the highest was 0.44 ppm, in 2023, below EPA’s legal limit of 10 ppm. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.87 ppm, in 2016.

What handles it

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

Chromium (total)

Comes from the source

Below EPA’s limits

3.0ppb

Highest yearly average, 2012 to 2018

2018: not found

Averaged by year, the highest was 3.0 ppb, in 2015, below EPA’s legal limit of 100 ppb. In 2018, the latest year on file, it wasn’t found in its one sample.

What handles it

  • 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 Indiana’s yearly averages as CDC publishes them, from 2022 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. Lyons Water Utility’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 Indiana cover 2022 to 2023; EPA’s compliance samples are from July 11, 2012 to July 17, 2018.

Testing your own tap

Lyons Water Utility’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 Indiana certifies.

The 3 labs Indiana certifies closest to the area Lyons Water Utility serves, in a straight line. Call first: certification is test by test, and not every lab takes samples from homeowners.

Indiana Department of Health laboratory: Test kits for well water: nitrate, fluoride, and arsenic, lead and copper, ordered from the lab and returned by mail. They are open to the public. Nitrate is $10 a sample plus $6.50 shipping per order, fluoride $10 plus shipping, and the arsenic, lead and copper kit $20 plus $6.50 shipping. Water Testing, Indiana Department of Health.
