Well water in Kossuth County

Private wells in Kossuth County are the owner's responsibility to test. Iowa DNR recommends that all private well owners test at least annually, with coliform bacteria and nitrate checked each year, and arsenic tested at least once. DNR also notes that nitrate, arsenic, and other contaminants occur naturally in some aquifers, and that shallow groundwater is more exposed to surface contaminants. DNR names manure, carcasses, and compost among human-caused sources of contamination. Published county-level well results were not found for Kossuth County, so testing your own well is the only way to know what is in it.

County facts checked October 2026 against: iowadnr.gov, iowadnr.gov, services.shl.uiowa.edu, iowadnr.gov.

Buying a home with a well in Ledyard: what happens at the sale

  1. 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.
  2. 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.
  3. 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.
  4. 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)).

Questions

Common questions.

Who needs well water testing in Iowa?
Any home on a private well, and above all one you are buying. Iowa DNR recommends testing a private well at least once a year, and also when a well is new, after work on the well or pump, and when the water changes in look, smell or taste.
Is well water testing part of the home inspection?
It is an add-on. Add it to your home inspection quote. Testing early in your inspection window leaves time to act on the results.
What should a Kossuth County owner do if a bacteria test comes back positive?
Iowa DNR recommends testing for coliform bacteria every year, and a positive result means the well should be addressed before the water is relied on. The Iowa DNR Private Well Grants Program lists shock chlorination and well assessment among the services it supports, through your county health department and a DNR-certified contractor.
Do you cover Ledyard?
Ledyard is inside our Buffalo Center team's range. This is drain-tile prairie, and town basements inherit the same slow drainage — so grading, sump performance and moisture lead nearly every report, with a sewer scope recommended on older laterals.
Does a septic system have to be inspected when an Iowa home is sold?
Yes, in most sales. Iowa Code 455B.172(11) requires a private sewage disposal system serving a building to be inspected before any transfer of ownership, and the county recorder will not record the deed without the inspector's report or a binding acknowledgment to inspect when weather prevents it. Only a DNR-certified time-of-transfer inspector may do it. Exemptions in the statute include transfers where the system was installed not more than two years earlier. An inspection is valid for two years. Because septic and well separation distances matter for water quality, a buyer of a home with both gets a fuller picture by testing the water alongside the septic report.
