The short answer

1 result is above the health goal. The worst: Uranium, 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.

Uranium, fluoride, arsenic and chromium (total): EPA’s compliance monitoring file, samples taken from July 1, 2014 to Aug. 5, 2019. Newer results are in the utility’s annual water quality report.

Above the health goal

0.26ppb

Highest yearly average, 2019

  • Chromium (total)
  • Lead
  • Nitrate

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?

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.

Filters with those claims on a certifier’s listing

None of the filters TapBuff has checked so far carry these claims. Search the certifier listings for the claim above.

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. Uranium, fluoride, arsenic and chromium (total) come from EPA’s file alone, which ends in 2019. Brookston 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 July 1, 2014 to Aug. 5, 2019.

Testing your own tap

Brookston 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 Brookston 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.
