Hillsborough County

EPA Zone 2

As Hillsborough County's largest city and the heart of the Tampa Bay Metro, Tampa sits on limestone bedrock covered by sandy soils that generally produce low-to-moderate radon levels. The city's predominantly slab-on-grade construction and warm climate typically result in lower indoor radon accumulation compared to northern states with basement foundations. However, with limited comprehensive testing data across Tampa's numerous zip codes, homeowners should still consider radon testing to ensure their indoor air quality meets EPA safety standards.
