At a glance

Water test for a new wellNot required statewide

No statewide water test. The state requires the well to be drilled by a DNR-licensed water well driller to the 312 IAC 13 construction standards (setbacks of 50 ft from septic tanks and drainfields, grouted casing, disinfection) and a well record filed with the Division of Water within 30 days. Most county health departments require a well permit under the county ordinance before drilling and many ask for a bacteriological sample before the well is approved for use, so check with the county first.

Water test when a home is soldNot required statewide

No statewide requirement. The Indiana seller's disclosure form asks whether the water supply is a well and whether there are known problems, nothing more. FHA, VA and USDA loans normally require a bacteria, nitrate and lead sample from a certified lab before closing, and a few county health departments require a well inspection at transfer.

What the state recommends

The Indiana Department of Health recommends testing a private well for coliform bacteria and nitrate every year and running a broader panel every few years or when something changes: arsenic (common in Indiana's glacial aquifers), iron, manganese, hardness, sulfate, sodium, lead and copper. Add radon, uranium and fluoride in south-central Indiana bedrock wells and PFAS near airfields and industrial sites, and test again after flooding, well work or a change in taste, color or smell.

Free or low-cost testingAvailable

No statewide free program. The Indiana Department of Health laboratory and most county health departments test private well samples for bacteria and nitrate for a small fee (typically $20 to $40 a sample), and several counties run periodic free testing days or arsenic screening. The IDOH lab finder below lists the certified labs that take samples from the public.
