Well water in Franklin County

Private wells in Franklin 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. Shallow wells can respond quickly to surface conditions. Published county-level well results were not found for Franklin 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.

Buying a home with a well in Latimer: 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 does DNR say about testing a Franklin County well for arsenic?
Iowa DNR says every private well should have at least one arsenic test. Arsenic occurs naturally in some aquifers, so the result cannot be guessed from appearance, taste, or a neighbor's well. If a result is elevated, DNR indicates testing may be needed more often, and water above EPA limits should not be consumed without proper treatment.
Do you cover Latimer?
Yes. Around Latimer footings set below the locally required frost depth still see settlement cracks and ice-dam wear, and the flat till that was tiled farm ground drains slowly around town basements.
Does Iowa offer free or low-cost private well testing?
Yes. Iowa's Private Well Grants program, also called Grants to Counties, is run through Iowa HHS with DNR technical help. It provides free water testing for private well owners. The listed analytes are bacteria/E. coli/coliform and nitrate annually, plus arsenic and manganese every 3 years. A county health specialist collects the sample, so you start by contacting your county health department and asking to take part in the program. Testing is the only way to know whether a well's water is safe, and a baseline result helps a buyer judge the water at a home with a private well.
What does a positive coliform or E. coli result mean?
Per the State Hygienic Laboratory, absent coliform and E. coli means the water is bacterially safe. Present total coliform means unsafe with potential health concerns. Present coliform and E. coli means unsafe with serious health concerns, because a pathway from a waste source such as a septic tank or feedlot may exist. Short term, boil water for one minute or use a known safe source, then find and fix how bacteria are entering the system. A coliform result is a lab indicator of a possible sanitary defect, and a home inspection of the wellhead looks for visible defects like a loose cap or poor drainage.
