You failed a radon test in Council Bluffs
A high result in Council Bluffs, Carter Lake, Underwood, or Missouri Valley is the expected outcome in a Zone 1 county in loess country. Confirm it, quote it, and negotiate from a written number.
The dominant local question is bistate: Council Bluffs homeowners shop the Omaha contractor pool constantly, and they ask whether a Nebraska-credentialed firm can work here. Bluff owners ask about walkout basements. Valley-floor owners ask whether a high water table changes the design — it usually improves it, because the drain tile gives the system somewhere to pull from.
What an elevated result actually means
Confirm in the same location under closed-building conditions. If a sale is running, confirm and quote in parallel. Bistate deals add a specific hazard here: buyers, agents, and inspectors working from Nebraska practice sometimes describe Iowa obligations inaccurately, and the reverse happens too. What governs an Iowa property is Iowa disclosure practice — a known elevated result goes in front of a buyer — and nothing in it compels a seller to install a system. Closed-house conditions from December through March give the most conservative readings. Missouri River valley springs bring high water and saturated ground, which can temporarily alter how soil gas moves through alluvium — a good reason to confirm a borderline reading taken during a wet stretch rather than acting on it directly.
Your next four steps
Four steps, in this order. Confirm the result — a second short-term test or a longer-term measurement, run under closed-building conditions. Get written quotes from independent businesses holding a current Iowa radon mitigation certification. Decide who pays, which in Iowa is a negotiation and not a legal mandate. Then verify with a post-mitigation test after the system runs. Nothing about a single elevated reading forces you out of your house or out of a contract. Ask for the post-mitigation test after twenty-four hours of runtime, in the original detector location, in writing with the Iowa mitigation certification number on the same page. On a walkout, confirm the detector location is the lowest lived-in level rather than wherever the crew found convenient.
If the result landed inside a deal
Iowa sellers disclose known radon information on the state residential disclosure form; nothing requires testing or mitigation. Metro buyers crossing from Nebraska should not assume the paperwork or credential matches — the two states operate under separate frameworks even though the metro functions as one market.

Failed Radon Test questions in Council Bluffs & Pottawattamie County
The buyer’s agent says Iowa requires mitigation above 4 pCi/L. Is that right?
No. Four picocuries per liter is EPA’s action recommendation, not an Iowa legal threshold that forces installation in a sale. Iowa practice centers on disclosure of what you know and on state certification for anyone doing measurement or mitigation for compensation. Whether a system gets installed, and who pays, is a term of your contract.
Does an elevated result put a sale in Council Bluffs at risk?
This is functionally part of the Omaha metro with an Iowa legal frame. Iowa disclosure practice and Iowa certification govern an Iowa property no matter where the agent, inspector, or contractor is based. Buyers crossing from Nebraska routinely carry expectations that do not match, and clarifying that early saves a lot of avoidable friction.
Am I legally required to mitigate in Iowa?
No. A result at or above 4 pCi/L is an EPA action recommendation, not an automatic legal obligation in a Iowa sale. What state law generally governs is disclosure — telling a buyer what you know — not whether a system gets installed. Who pays, and whether the work happens before closing, is negotiated between buyer and seller.
