The short answer

1 result is above the health goal. The worst: Arsenic, above the health goal. No health-based violations on file since 2016.

What handles it

What was found

Haloacetic acids (HAA5), total trihalomethanes (TTHM) 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 March 29, 2012 to Dec. 17, 2019. Newer results are in the utility’s annual water quality report.

Above the health goal1

Arsenic

Comes from the source

Above the health goal

8.8ppb

Highest yearly average, 2012 to 2019

2019 average: 0.6 ppb

Averaged by year, the highest was 8.8 ppb, in 2015: below EPA’s legal limit of 10 ppb, but above its health goal of zero. Its highest single sample was 11.1 ppb. In 2019, the latest year on file, its three samples averaged 0.6 ppb. EPA recorded no violation for arsenic at this utility from 2012 to 2019.

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 limits4

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.95ppm

Highest yearly average, 2012 to 2018

2018 average: 0.64 ppm

Averaged by year, the highest was 0.95 ppm, in 2015, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 0.95 ppm. In 2018, the latest year on file, its two samples averaged 0.64 ppm.

What handles it

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

7.2ppb

Highest yearly average, 2022 to 2023

2023 average: 4.8 ppb

Averaged by year, the highest was 7.2 ppb, in 2022, below EPA’s legal limit of 60 ppb. In 2023, the latest year on file, it averaged 4.8 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 5.0 ppb, in 2019.

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

3.2ppb

Highest yearly average, 2022 to 2023

Averaged by year, the highest was 3.2 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 3.5 ppb, in 2019.

  • NSF/ANSI 58 look for “Trihalomethanes (TTHM) Reduction”

Chromium (total)

Comes from the source

Below EPA’s limits

0.5ppb

Highest yearly average, 2012 to 2018

2018: not found

Averaged by year, the highest was 0.5 ppb, in 2015, below EPA’s legal limit of 100 ppb. Its highest single sample was 1.0 ppb. In 2018, the latest year on file, it wasn’t found in its one sample.

What handles it

3 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Lead
  • 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

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

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

  • NSF/ANSI 58

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

    Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)

At the tap, or for the whole house?

These come with the water itself, so a whole-house system certified for the same claims treats every tap and shower. A filter at the tap treats drinking water for much less. How whole-house systems compare.

What this report can’t tell you

  • Everything else. Haloacetic acids (HAA5), total trihalomethanes (TTHM) 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. Boswell 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 March 29, 2012 to Dec. 17, 2019.

Testing your own tap

Boswell 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 Boswell 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.
