The short answer

2 results are above the health goal. The worst: Lead, above the health goal. 6 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 1993 to 2024.

Nitrate, total trihalomethanes (TTHM), haloacetic acids (HAA5) and arsenic: 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.

Uranium, fluoride and chromium (total): EPA’s compliance monitoring file, samples taken from June 23, 2014 to Jan. 31, 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

15ppb

90th percentile, 2022 to 2024

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

What handles it

Uranium

Comes from the source

Above the health goal

2.2ppb

Highest yearly average, 2018

Averaged by year, the highest was 2.2 ppb, in 2018: below EPA’s legal limit of 30 ppb, but above its health goal of zero. That is the only year on file.

What handles it

Below EPA’s limits4

Nitrate

Comes from the source

Below EPA’s limits

9.7ppm

Highest yearly average, 2022 to 2023

2023 average: 4.9 ppm

Averaged by year, the highest was 9.7 ppm, in 2022, below EPA’s legal limit of 10 ppm. In 2023, the latest year on file, it averaged 4.9 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 6.0 ppm, in 2019.

Below EPA’s limits

38ppb

Highest yearly average, 2022 to 2023

Averaged by year, the highest was 38 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 37 ppb, in 2018.

Below EPA’s limits

1.2ppm

Highest yearly average, 2014 to 2017

Averaged by year, the highest was 1.2 ppm, in 2017, below EPA’s legal limit of 4.0 ppm. That was also the latest year on file.

What handles it

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

9.8ppb

Highest yearly average, 2022 to 2023

Averaged by year, the highest was 9.8 ppb, in 2023, below EPA’s legal limit of 60 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 27.1 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.”

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. Nitrate, total trihalomethanes (TTHM), haloacetic acids (HAA5) and arsenic results here are Indiana’s yearly averages as CDC publishes them, from 2022 on, with EPA’s national file for 2012 to 2019. Uranium, fluoride and chromium (total) come from EPA’s file alone, which ends in 2019. Edwardsport 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 June 23, 2014 to Jan. 31, 2018.

Testing your own tap

Edwardsport 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 Edwardsport 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.
