Indiana: private well + septic
Indiana combines nonbinding statewide private-well standards with a clear annual and five-year health schedule, while county health departments can impose permits, completion samples, or property-transfer tests that do not apply statewide.
Indiana-specific value comes from its recommended statewide new-well panel, annual and five-year testing clocks, enforceable county exceptions, analyte-scoped laboratory directory, and field-verified-versus-estimated well-record distinction.
IDOH recommends annual bacteria and nitrate testing and fluoride, arsenic, lead, and copper at least every five years, with a separate recommended panel after new construction or major maintenance.
Indiana homeowner guidance commonly uses three-year inspections and a three-to-five-year pumping range, while local health departments administer property-specific permits and records.
Indiana DNR licenses drillers and holds well records, IDOH publishes health and construction recommendations and certifies laboratories, and local health departments administer county-specific well and septic requirements.
Search the Indiana DNR Water Well Record Database, obtain the driller copy, and ask the county health department for permits, test reports, and local transfer requirements.
Private well testing overview
Indiana uses different testing paths for different moments.
New-well completion, routine ownership, a home purchase, and a flood or repair are not the same testing decision. Use the dedicated guide for the exact timing, required parameters, laboratory route, and county records to request.
