Well Water Testing in Harcourt

Water testing for Iowa homes, above all those on a private well. An accredited laboratory can test the water for coliform bacteria and E. coli, nitrate, arsenic and more. Iowa DNR recommends testing a private well at least once a year.

Harcourt is a Webster County town at the U.S. 169 and Iowa 175 junction, platted in 1881 and once a stop on the Fort Dodge interurban. Housing here runs to early-1900s homes from the railroad and interurban era, with postwar houses toward the highway, across the grid between U.S. 169 and Iowa 175 and the acreages beyond it.

Well water in Webster County

Private wells in Webster 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 also recommends at least one lead test for private water systems. Published county-level well results were not found for Webster County, so testing your own well is the only way to know what is in it.

Buying a home with a well in Harcourt: 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.
When is the best time to test a Webster County well?
Iowa DNR recommends testing at least annually, and also whenever the well is new, after well, pump, or water system service, after a power outage that causes a loss of water pressure, or when the water looks, smells, or tastes different. Keeping a consistent yearly schedule makes changes in results easier to spot.
Do you inspect acreages around Harcourt?
Yes. Properties outside town add a private well and a septic system to the inspection, plus outbuildings if you want them documented. In town, Harcourt's older stock gets services and foundations dated precisely and a sewer-scope recommendation on tree-lined streets. Either way the flat, tiled till drains slowly, so grading and sump performance are checked closely, and a 48-hour radon test is recommended countywide.
How is a well shock chlorinated, and what does Iowa DNR say about retesting?
DNR's flood guidance says if a well is positive for coliform or E. coli, purge and shock chlorinate the well and water system, then retest for bacteria, fecal coliform and nitrate 7 to 10 days later, repeating until there is zero coliform and fecal coliform. Iowa's well rules (567 IAC 49.24) call for chlorine to reach every part of the well and stay in contact long enough. Shock chlorination does not remove Giardia or Cryptosporidium. A follow-up lab test is the check that a disinfection actually cleared bacteria from the well.
Who do I call to get my well tested?
Call your county environmental health department and ask for the county sanitarian (environmental health specialist). DNR says local county health departments can help but you must contact them to start testing. Under the grant guidance the county health specialist must collect the samples, and the sanitarian can also help interpret results. DNR keeps a county contact spreadsheet that ISU Extension links to from its drinking water page. A lab result from a properly collected sample is what turns a guess about well water into a documented answer.
