What 11.8 pCi/L means for your Colfax home
Jasper County ranks 5th of Iowa's 99 counties for average indoor radon, at 11.8 pCi/L in tests reported to the CDC from 2008 through 2017, against a U.S. average of 1.3 and an Iowa average of 8.5. That is higher than Polk County's 7.3, so a Colfax home is, on average, more likely to test high than one in the Des Moines suburbs. Levels vary house to house, even next door, so the only number that matters for your Colfax home is the one from a certified test in your own basement.
The county figure tells you the odds; a certified test tells you the answer. We place a continuous monitor in your Colfax home for 48 to 72 hours and email the report the day it comes out. If it reads 4 pCi/L or higher, you get a written mitigation quote the same day, and every system we install is guaranteed below 2.7 pCi/L.
Free radon test kit for Colfax homes
Yes. Colfax is in a rural Iowa county covered by the state's free radon test kit program.
Healthy Hometowns: Combat Cancer, run by Marion County Public Health with local health departments across rural Iowa, provides one free radon test kit per household while supplies last. Request it through the program's order form, or ask Jasper County Public Health.
Request a free kit (Healthy Hometowns: Combat Cancer) →A free kit is a mailed charcoal test: results take a couple of weeks, one kit can miss a high reading, and it is not accepted for a real-estate sale. If it comes back at 4.0 pCi/L or higher, the next step is a certified 48-to-72-hour monitor test with same-day results, then a same-day mitigation quote.
The same program is funding mitigation help for rural homeowners whose homes test high. If your kit comes back at 4.0 pCi/L or above, call us: we confirm the number with a certified monitor test, quote a system the same day, and point you to your Jasper County program contact for any assistance you qualify for.

Radon in Colfax Homes
Home to 2,255 people and growing at 17% a decade, Colfax pairs an older railroad-era town center with newer construction on its edges. Older homes here often have block walls and sometimes a crawl space; the newer ones have poured basements and sump pits. We size the system to the foundation, not the town.
With about 1,260 residents per square mile over 1.79 square miles, Colfax has the lot sizes of a traditional Iowa town: detached houses, side yards, and room to put the fan and vent where they are least visible. Routing is rarely the hard part here; the foundation is.
Colfax is about 21 miles east of downtown Des Moines. Our nearest other stops are Prairie City (6 mi), Mingo (6 mi) and Mitchellville (7 mi), so a Colfax visit usually pairs with jobs nearby. A standard test is a 48-to-72-hour continuous monitor with the report emailed the day it comes out; a mitigation is usually a single visit, with the fan on the least visible side of the house and the vent above the roofline. Every system we install in Colfax is guaranteed below 2.7 pCi/L.

Colfax Radon Questions
Is Colfax in All Midwest Radon's service area?
We do. Our Jasper County route covers Colfax and its neighbors Prairie City, Mingo, Mitchellville, 21 miles out from Des Moines. Tests are scheduled seven days a week and mitigation visits are booked like any metro job.
How high is radon around Colfax?
11.8 pCi/L, based on tests reported to the CDC Tracking Network from 2008 through 2017. That ranks 5th of Iowa's 99 counties and is 3.0 times the EPA action level of 4 pCi/L. Individual Colfax homes test both far above and below that average, which is why a test of your own home is the only reliable answer.
Can I get a free radon test kit in Colfax?
Yes. Jasper County households can request one free short-term radon test kit through Healthy Hometowns: Combat Cancer, the state program for rural Iowa, while supplies last. A kit is a good first look, but results take weeks and it is not accepted for a home sale. A certified 48-to-72-hour monitor test gives same-day results, and any reading at 4.0 pCi/L or above should be confirmed that way before mitigation.
What does a mitigation install in Colfax involve?
Most Colfax installs are completed in a single visit. We place a sealed suction point in the slab or sump pit, route the vent pipe to an exterior fan, and finish above the roofline, then run a post-mitigation clearance test. Every system is guaranteed to bring the home below 2.7 pCi/L.
Is a radon test required to sell a home in Colfax?
No. Iowa Code chapter 558A is a disclosure law: a seller must disclose any known test results and provide the Iowa Radon Home Buyers and Sellers Fact Sheet, but no law requires the test itself. In practice the buyer orders a certified test during the inspection period, and with Colfax adding homes as fast as it has, that is a test we run often. We schedule those seven days a week.
