Radon Testing & Mitigation in Jerome, ID

Jerome sits just north of Twin Falls across the Snake River Canyon, the seat of Jerome County and a community built on Magic Valley agriculture. It shares the same Snake River Plain basalt geology that produces radon across the region, and like the rest of the area, it's been lightly tested, part of why Twin Falls County and its neighbors rank among Idaho's most undertested for radon. The Idaho Department of Health and Welfare estimates roughly 2 in 5 Idaho homes test above the 4.0 pCi/L action level, and Jerome homes sit on the same ground that drives those numbers.

Jerome's housing skews agricultural and older, with a historic Main Street core and a lot of farm and rural properties, some dating back to the early 1900s (the area even has historic lava-rock farm buildings on the National Register). Older foundations, whether basement, crawl space, or a mix from additions over the decades, tend to have more of the cracks and joints radon uses to move indoors, which is exactly the range an experienced provider designs systems around. Crawl-space homes use sub-membrane depressurization; basements and slabs use sub-slab systems.

The well-water angle is especially relevant in Jerome. This is farm country, and a large share of rural Jerome County homes draw from private wells. Radon dissolved in well water is released into indoor air during showering and dishwashing, so if your air test comes back high and you're on a well, testing the water is worth discussing with your provider.
