Radon Testing in Melcher-Dallas

Radon Testing in Melcher-Dallas, Marion County, by Closer Look Inspectors. Melcher-Dallas is two merged coal towns with two separate historic cores in one city.

Radon testing places an EPA-protocol continuous monitor on a home's lowest livable level to measure radon gas — and it matters across Iowa, where Iowa HHS reports 71.6 percent of homes above the action level — the largest percentage of any state.

Local housing

Homes in Melcher-Dallas.

Melcher-Dallas housing runs to early-1900s coal-era housing in two distinct cores — Dallas established 1855 and incorporated 1911, Melcher established 1913 — with postwar additions, across the Dallas core, the Melcher core, and the coal ground between and around them; the two towns merged into one city in 1986, on Southern Iowa Drift Plain loess and pre-Illinoian till, undermined across the area by Marion County's historic coal workings — and that mix shapes what a radon testing here needs to find.

Local conditions in Melcher-Dallas

No Iowa law requires a home inspection before a sale — the one mandatory time-of-transfer inspection covers private septic systems (Iowa Code 455B.172) — which makes an independent inspection the only thorough, buyer-side read on a Melcher-Dallas home. Melcher-Dallas sits in Marion County, and every Iowa county is EPA Radon Zone 1. Iowa HHS reports Iowa has the largest percentage of homes above the 4.0 pCi/L action level of any state — 71.6 percent in the Iowa Radon Survey — and the Iowa seller disclosure form asks for any known radon test results. Finished basements concentrate it, and only a 48-hour test gives you this home's number. Iowa leaves frost depth to the local building code rather than one statewide number, and the annual freeze-thaw cycle drives the settlement cracks and ice-dam wear that Melcher-Dallas-area homes face.

Questions

Common questions.

Is radon really a concern in Iowa?
Yes. The Iowa Department of Natural Resources reports that more than two in five Iowa homes have radon levels that pose a significant health risk, and finished basements are where it concentrates.
How long does the test run?
A 48-hour minimum under closed-house conditions; the result is delivered with your inspection report.
Why does Melcher-Dallas need to be treated as two towns in one?
Because it is. Dallas was established in 1855 — originally called Ohio, for the Ohio-born miners — and incorporated in 1911; Melcher was established in 1913; the two merged into a single city in 1986, and Merger Day is still celebrated each May. That leaves two separate historic cores with different platting, different street-era utilities and different housing vintages inside one municipality, so a comparison drawn from one side can mislead you about the other. Add the coal history — 18 mines within a 20-mile radius, mines closing in 1952 — and the Iowa DNR mine map is worth a look by address.
