Underwood and Pottawattamie County

Underwood routes through our Pottawattamie County territory with Council Bluffs, Crescent, and Carson. EPA places Pottawattamie County in Zone 1 on its Map of Radon Zones. Iowa certifies radon measurement and mitigation specialists through the state health department.

If the result surfaced in a transaction

Family moves drive the local market, concentrated around school calendars. Iowa sellers disclose known radon information on the state disclosure form; mitigation remains negotiated. In newer sections, checking for a builder-installed passive rough-in is the useful first diligence step.

Those duties are set in Iowa, not in Pottawattamie County — Iowa radon disclosure rules has the statute and the agency behind it, including what a seller must hand over and what stays negotiable.

The housing you’re mitigating

Expect newer poured foundations with full basements, sump systems, and attached garages, alongside older village homes on block foundations with partial basements. Rural-edge properties add mixed-foundation farmhouses and private wells raising a separate radon-in-water question.

Underwood questions, answered straight

Is there a way to check for builder-installed radon piping ourselves?

Find the attic run: 3- to 4-inch PVC exiting the roofline, commonly labelled, with its lower end below the basement floor. If it exists and your test is elevated, a certified contractor can add an in-line fan and indicator — a smaller job than a full retrofit.

Should a well household order two different measurements?

Potentially. The airborne test covers the house; a separate water test tells you whether radon is arriving dissolved in well water. Fix the air first, then let the water result decide.

We are about to finish the lower level. Does the system go in first?

Yes. Routing is easiest and least expensive while the space is open, and a verified slab underneath means the finished room starts from a known number.

The kit says to keep the house closed. What does that actually require?

Windows and exterior doors stay closed apart from ordinary entry and exit, for 12 hours before a short-term test begins and throughout the measurement. No whole-house fan, no window air conditioner. Permanent HVAC equipment runs on its usual settings. In an Underwood spring or autumn, an open window is the most common reason a result gets discarded — and inside a purchase contract, a compromised test is one the other party can fairly refuse to accept.

Can we rely on a nearby test result instead of running our own?

Barely. What drives an indoor result is the ground under your own footprint, the number and size of openings through your slab, and the pressure your house pulls on that soil — all three change from address to address. Underwood homes on the same road, built in the same era, land on opposite sides of 4 pCi/L often enough that borrowing a neighbour's number is a guess. Their result is a reason to test your own address.
