When to test your water
- Every yearColiform bacteria and nitrate, the basic safety checks for a private well.
- At least onceArsenic and manganese. Iowa DNR's testing list repeats arsenic every 3 years.
- Before a baby drinks the waterNitrate. Water above 10 mg/L as nitrogen should not be used for infant formula or juice.
- When you buy a homeA full baseline while you can still ask questions or negotiate.
- New well or well workWhen a well is new and after service on the well or pump.
- After a flood or power outageIf flood water was near or reached the well, or an outage dropped the water pressure.
- When taste, color or smell changesA change in the water is a reason to test.
- Near a fuel tankVOCs, plus DRO for diesel and fuel oil. Iowa DNR names gasoline among the VOCs some wells are susceptible to, and Iowa's well rules list 100 feet between a well and a liquid fuel storage tank other than propane.
- City water in an older homeLead. Iowa DNR says homes built before 1986 are more likely to have lead pipes, fixtures and solder.

Buying a home with a well in Newton: 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)).

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.
My home is on city water in Iowa. Is water testing still worth it?
Often, yes. Lead in drinking water comes mainly from service lines and home plumbing. Iowa DNR says a water system cannot control the materials used in home plumbing. Your utility sends a Consumer Confidence Report each year. Under the federal Lead and Copper Rule, utilities sample selected homes, those more likely to have lead plumbing. Iowa community water systems had to prepare a lead service line inventory under the federal rule, and it must be publicly available. DNR expects homes built after 1988 to have service lines made of something other than lead. To learn what your service line is made of, ask your water utility. DNR also notes that utilities are not required to offer lead testing on request. EPA says testing is the only sure way to know whether harmful amounts of lead are in your water.
How often should a Jasper County well be tested?
Iowa DNR recommends testing at least once a year, with coliform bacteria and nitrate every year and arsenic at least once. Test sooner when a well is new, after work on the well or pump, after a power outage that drops water pressure, and when the water changes in look, smell or taste.
Does Newton's Maytag-era stock inspect differently?
It rewards patience. The neighborhoods built during the washer works' boom are solid but now past a century — original panels upgraded to varying standards, layered plumbing, and foundations that have settled into the rolling clay. We separate what has been genuinely renewed from what was merely painted, and Jasper County's Zone 1 radon standing makes the 48-hour test routine.
When should I test the water if I'm buying a home with a well?
DNR recommends testing when a well is brand new, after any service on the well or pump, after power outages that cause loss of pressure, and when water looks, smells or tastes different. Treat a purchase like a new-owner situation: the owner of the well is responsible for its testing. Coliform bacteria and nitrate are annual tests, and arsenic is recommended at least once. A coliform, nitrate and arsenic test on the well before closing gives the buyer a lab result for the water they will be drinking.
Is there arsenic in Iowa well water?
Arsenic occurs naturally in Iowa rocks and soil, and DNR says it is present at some level in groundwater in many areas of the state. A 2006-2008 University of Iowa survey for DNR found detectable arsenic in 48 percent of 475 sampled rural wells, and 8 percent were at or above 0.01 mg/L (10 ppb). High arsenic was most common in north-central Iowa. Only a lab test shows your well's level. Arsenic cannot be seen, tasted or smelled, so a lab test during a home purchase is how a buyer learns the level in that well.
