Well water in Mitchell County
Mitchell County sits in or near northeast Iowa's carbonate-bedrock area. The Iowa Geological Survey lists Floyd and Mitchell counties, noted as especially affected, among counties with large numbers of sinkholes, and says sinkholes may occur where glacial cover over bedrock is under 50 feet thick. Iowa DNR says karst features can let surface water reach shallow groundwater immediately, and that karst wells need more frequent water quality monitoring. DNR recommends coliform bacteria and nitrate testing every year and arsenic at least once. County-specific well results were not found, so test your own well.
County facts checked October 2026 against: iowadnr.gov, iowadnr.gov, iowageologicalsurvey.uiowa.edu.
Iowa DNR recommends testing a private well at least once a year, with coliform bacteria and nitrate every year.

Buying a home with a well in Orchard: what happens at the sale
- Groundwater Hazard StatementIowa Code 558.69 requires a groundwater hazard statement filed with the declaration of value when a listed condition (including any known well and its status under 455B.190, or a private sewage disposal system) exists on the property, signed by a seller or agent, with a copy given to the buyer.
- Wells on the propertyIf known wells are on the property, the statement must give the approximate location of each and its status under Iowa Code 455B.190 (abandoned wells properly plugged); the owner is responsible for the accuracy of the information.
- Septic time-of-transfer inspectionIowa Code 455B.172(11) requires a private sewage disposal system serving a building to be inspected before any transfer of ownership, by a DNR-certified inspector, and the county recorder will not record the deed without the report or a binding acknowledgment.
- Failing systemsA system that is failing to treat wastewater must be renovated to current standards by the seller or, by agreement and within a reasonable time set by the county board of health or DNR, by the buyer (455B.172(11)(c)).
