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

Uranium, nitrate and arsenic: Indiana’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2023.

Above the health goal1

Above the health goal

0.32ppb

Highest yearly average, 2023

Averaged by year, the highest was 0.32 ppb, in 2023: below EPA’s legal limit of 30 ppb, but above its health goal of zero. That is the only year on file.

0.75ppm

Highest yearly average, 2023

Averaged by year, the highest was 0.75 ppm, in 2023, below EPA’s legal limit of 10 ppm. That is the only year on file.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”
2 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Arsenic
  • Lead

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. Uranium, nitrate and arsenic results here are Indiana’s yearly averages as CDC publishes them, from 2023 on, with EPA’s national file for 2012 to 2019. The Hills at St. Joe Farm’s own annual report, which it must send you every year, has 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 2023.

Testing your own tap

The Hills at St. Joe Farm’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.
