The short answer

2 results are above the health goal. The worst: Arsenic, above the health goal. 1 health-based violation since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 1995 to 2025.

Nitrate: Indiana’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2023, with EPA’s 2012 to 2019 file for earlier years.

Arsenic, fluoride and chromium (total): EPA’s compliance monitoring file, samples taken from June 28, 2012 to Aug. 15, 2019. Newer results are in the utility’s annual water quality report.

Above the health goal2

Arsenic

Comes from the source

Above the health goal

8.1ppb

Highest yearly average, 2012 to 2019

Averaged by year, the highest was 8.1 ppb, in 2019: below EPA’s legal limit of 10 ppb, but above its health goal of zero. Its highest single sample was 12.4 ppb. That was also the latest year on file. 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”

Lead

Comes from pipes, often your own

Above the health goal

1.6ppb

90th percentile, 2025

In the latest period, 9 in 10 homes sampled were at or below 1.6 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.

What handles it

Below EPA’s limits2

Fluoride

Forms or is added in treatment

Below EPA’s limits

1.2ppm

Highest yearly average, 2012 to 2018

Averaged by year, the highest was 1.2 ppm, in 2018, below EPA’s legal limit of 4.0 ppm. That was also the latest year on file.

What handles it

Chromium (total)

Comes from the source

Below EPA’s limits

6.0ppb

Highest yearly average, 2012 to 2018

2018: not found

Averaged by year, the highest was 6.0 ppb, in 2015, below EPA’s legal limit of 100 ppb. In 2018, the latest year on file, it wasn’t found in its one sample.

What handles it

One compound tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • 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.”

  • NSF/ANSI 53

    Claims: Arsenic (Pentavalent)<=50 ppb Reduction, Lead Reduction

    For: Arsenic, Lead

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

  • NSF/ANSI 58

    Claims: Arsenic (Pentavalent)<=50 ppb Reduction, Lead Reduction

    For: Arsenic, Lead

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

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 results here are Indiana’s yearly averages as CDC publishes them, from 2023 on, with EPA’s national file for 2012 to 2019. Arsenic, fluoride and chromium (total) come from EPA’s file alone, which ends in 2019. Fairmount MHP, L.P.’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 2023; EPA’s compliance samples are from June 28, 2012 to Aug. 15, 2019.

Testing your own tap

Fairmount MHP, L.P.’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.
