Waterloo, What is published
Radon data is published by county, not by city
Radon data is published by county, not by city. EPA assigns radon zones to counties, and CDC publishes radon test figures by county. Neither publishes a figure for Waterloo, so every radon figure on this page belongs to a county and is labelled with it. Only a test tells you about one home.
Black Hawk County has an EPA zone and its own CDC test figures, shown below. About 66,919 people live in Waterloo.
Waterloo, Counties
Each county's own EPA zone and its own published CDC figures for 2008 to 2017, laboratory, the newest period any of them has. A county without a figure for that period is shown without one, never with a figure from another year.

Who to ask in Iowa: the state's radon program, test kits and professionals.
Iowa Department of Health and Human Services
Iowa’s radon program answers questions about testing, mitigation and the rules where you live.
Iowa’s radon program approves applications for persons who wish to become certified to perform radon testing or credentialed to perform mitigation and laboratories that provide radon testing devices and analytical services.
However, per Iowa Code chapters 543B.9 and 543B.18 and Iowa Administrative Code 193E Chapter 14 administered by the Iowa Real Estate Commission, a seller must disclose any known tests for the presence of radon and if yes, provide the date of last report and the result(s).
The program says: You can reach the Hotline by calling 1-800-383-5992 to order low-cost radon test kits and find answers to your radon questions.

Professionals in IowaWaterloo, Questions
EPA's Map of Radon Zones classifies counties, not cities. Black Hawk County is in Zone 1 (highest predicted potential). A zone is a prediction for a whole county and never tells you the level in one home.
For 2008 to 2017, laboratory, the share of radon tests reported to CDC that were at or above 4 pCi/L was 48.4% in Black Hawk County (3,223 tests). Each is that county's own figure, counting tests reported to CDC, not homes. Radon411 does not average or combine them into a figure for the city.
Yes. Testing is the only way to know the radon level in a specific building. EPA recommends fixing a home when the radon level is 4 pCi/L or higher. EPA recommends considering a fix when the level is between 2 and 4 pCi/L. How to test a home.
The answers use the published figures of Black Hawk County, the county Waterloo lies in.
