Black Hawk Homes Face Significant Radon Exposure Risk
Black Hawk is an unincorporated community in Meade County, South Dakota, situated along Interstate 90 between Rapid City and Sturgis. With a population of roughly 3,000, Black Hawk serves as a popular residential corridor for families who want proximity to Rapid City's amenities while enjoying a more rural, spacious setting. However, the same geological conditions that define the northern Black Hills foothills also produce some of the highest radon levels in the country — and Black Hawk sits right in the middle of this high-risk zone.
Meade County is designated EPA Zone 1 for radon, meaning the predicted average indoor screening level exceeds 4 pCi/L. The soils in the Black Hawk area are composed of weathered shale, sandstone, and alluvial deposits from ancient waterways. These soil types are highly permeable, allowing radon gas to travel freely from uranium-bearing bedrock into the crawlspaces and basements of residential homes. The seasonal temperature swings in western South Dakota — from well below zero in winter to over 100 degrees in summer — create stack-effect pressure differentials that actively draw radon into heated or cooled homes.
Why Black Hawk's Housing Mix Creates Unique Radon Challenges
Black Hawk's housing stock is diverse, ranging from manufactured homes and modular buildings to custom-built ranch homes and newer two-story developments. Each foundation type presents different radon entry points. Manufactured homes set on piers or skirted crawlspaces can accumulate radon in the air space beneath the floor. Homes with poured concrete basements may have radon seeping through hairline cracks that are invisible to the naked eye. Split-level and bi-level homes — common in the area — have multiple foundation transitions that create additional pathways for soil gas intrusion.
Properties along Black Hawk Road, Seger Drive, and the areas surrounding the Black Hawk community center and fire station have all produced elevated radon test results. Many homeowners in these neighborhoods have discovered levels of 8, 12, or even 20+ pCi/L — far above the EPA action level. Because radon is invisible and odorless, many families live with dangerous exposure for years before testing.
