The short answer

2 results are above EPA’s legal limit, and 1 more is above the health goal. The worst: Total trihalomethanes (TTHM), above the legal limit. 8 health-based violations since 2016.

What handles it

What was found

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

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.

Fluoride, arsenic, chromium (total) and uranium: EPA’s compliance monitoring file, samples taken from June 25, 2012 to Sept. 18, 2018. Newer results are in the utility’s annual water quality report.

Above the legal limit

59ppb

Highest yearly average, 2022 to 2023

Averaged by year, the highest was 59 ppb, in 2023, below EPA’s legal limit of 80 ppb. That was also the latest year on file. EPA judges this limit at each sampling point, and recorded violations for total trihalomethanes (TTHM) at this utility in 2020, 2021 and 2023. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 58.3 ppb, in 2015.

39.8ppb

Highest yearly average, 2022 to 2023

Averaged by year, the highest was 39.8 ppb, in 2023, below EPA’s legal limit of 60 ppb. That was also the latest year on file. EPA judges this limit at each sampling point, and recorded violations for haloacetic acids (HAA5) at this utility in 2020 and 2021. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 36.2 ppb, in 2015.

Above the health goal

1.4ppb

90th percentile, 2022 to 2024

In the latest period, 9 in 10 homes sampled were at or below 1.4 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.

Below EPA’s limits

0.99ppm

Highest yearly average, 2012 to 2018

2018, one sample: 0.85 ppm

Averaged by year, the highest was 0.99 ppm, in 2015, below EPA’s legal limit of 4.0 ppm. In 2018, the latest year on file, its one sample was 0.85 ppm.

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: Trihalomethanes (TTHM) Reduction, Lead Reduction

    For: Total trihalomethanes (TTHM), Lead

    Other certifiers’ wording: VOC Reduction

  • NSF/ANSI 58

    Claims: Trihalomethanes (TTHM) Reduction, Lead Reduction

    For: Total trihalomethanes (TTHM), 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. 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. Fluoride, arsenic, chromium (total) and uranium come from EPA’s file alone, which ends in 2019. Kirklin Water Department’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 25, 2012 to Sept. 18, 2018.

Testing your own tap

Kirklin Water Department’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 Kirklin Water Department 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.
