Well water testing in Elkhart County, Indiana

Elkhart County has more people on household wells than any other Indiana county in USGS's estimates. The county health department says some areas have naturally high arsenic, and it requires new wells to be tested. Here's what to test, where, and what to know if you're buying. Every fact has a source.

This page can't tell you whether your water is safe to drink. Only a test of your well can do that. For help, contact the Elkhart County Health Department, listed below.

How many people here use a private well

USGS estimates that about 92,000 people in Elkhart County supplied their own household water in 2015, about 45% of the county's population, the most of any Indiana county.1

Arsenic and other concerns

County rules for wells

Under Elkhart County Ordinance 2017-24, the county health department requires a permit for new wells, and new wells must be tested for total coliform, E. coli, nitrate and arsenic.2

What to test and how often

The Indiana Department of Health (IDOH) says to test well water at least once a year.6 Its lab suggests bacteria and nitrate every year and fluoride, arsenic, lead and copper every five years.7 Given the county's arsenic warning, don't skip arsenic.
