South Dakota Radon Information

South Dakota Radon Program:

Radon Website: Website
Radon Contact: Barbara Regynski
Active Radon Program: Yes
Require License for Radon Professionals: No

South Dakota is the 17th most expansive state in terms of size but the 5th least populous. It also happens to be the 5th least densely populated state in the entire US.

South Dakota does have an active radon program, dedicated to educating citizens about the risks associated with the deadly gas. You can find more information on Radon, testing and mitigation at the official page.

The radon levels in South Dakota are moderate to low in many areas of the state. That being said, there is an increased risk for all homeowners, which is why we recommend testing exposure levels at least twice a year.

South Dakota Radon Levels

Map of South Dakota Radon Levels

Zone 1 (1): Potential for radon levels above 4 pCi/L according to EPA
Zone 2 (2): Potential for radon levels between 2 pCi/L and 4 pCi/L according to the EPA
Zone 3 (3): Lowest EPA level with expected radon levels at or below 2 pCi/L
Disclaimer: It is strongly recommended that all households, schools and office spaces test radon levels individually. The EPA Radon Zone data is not an indicator of individual test results, but a guideline for strategic planning. Toxic radon levels can be found in all counties, regardless of their zone rating. While we make efforts to keep this information up to date, it is derived from third­party sources which may not be accurate or reflect the most current statistics.

South Dakota Radon Statistics

South Dakota has 65 counties and 47 (72%) have been assigned Zone 1 counties by the EPA. Zone 1 counties have the highest potential to have homes test higher than 4 pCi/L. South Dakota's state radon zone average is 1.28, which is the average of all county zone ratings the EPA has assigned the state, ranking it 10 among all states.

South Dakota Radon Contractor License Information

Does South Dakota require contractors to be licensed? No.

What are the licensing requirements? There are no state mandated requirements to become a licensed radon contractor in South Dakota. Those looking for a radon certification can take qualified third party courses that are offered through the NRPP or AARST.

South Dakota Radon Real Estate Requirements

Does the state of South Dakota require radon testing for all real estate transactions? No

However both the state of South Dakota and the EPA recommend that a home or residence should be tested before a real estate transaction is carried out. Even though South Dakota does not require radon testing, we certainly recommend you have a test performed before you purchase a home. If you decide to perform a test after and find elevated levels, there is no reason to panic. South Dakota radon mitigation is not expensive compared to the dangers and a system can be implemented in a relatively short period of time.
