Buying a home with a well in Pleasant Hill: 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.
How often should an acreage well near Des Moines be tested?
The Iowa DNR's private well page lists bacteria and nitrate as annual tests, and recommends every private well be tested for arsenic at least one time, with more testing if levels are elevated.Your county health department is the DNR's suggested starting contact.
What is specific to Pleasant Hill?
The ground. Much of the city sits where flat till breaks toward the Des Moines River valley, so slope drainage, retaining walls and foundation movement on graded lots get particular attention, alongside the usual radon priority — Polk County is Zone 1.
Can I order a test kit from the State Hygienic Laboratory instead?
Yes. If the sanitarian cannot collect your sample or you prefer to do it yourself, the State Hygienic Laboratory at the University of Iowa supplies sampling kits with sterile bottles and instructions. Use only the bottle the lab provides, since the coliform and nitrate bottles are specially prepared. The lab says samples should reach it within 48 hours of collection, so ship the same day and avoid Fridays and holidays. A water test during the sale of a home gives both sides lab data on the well rather than assumptions.
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.
