Radon mitigation in West Jordan, Utah
West Jordan sits in the part of the valley the Utah Geological Survey studied specifically for radon-hazard potential, and its southeast area has some of the highest state test results in Salt Lake County.
West Jordan at a glance. In Utah's state test-kit data (2006–2019), southeast West Jordan averaged 5.5 pCi/L, with 52% of tests at or above 4. Northeast averaged 4.8 (49%) and the west side, including Copperton, averaged 4.5 (33%) (Source: Utah IBIS).

What the geology says about the west side of the valley
The Utah Geological Survey mapped radon-hazard potential for the western Salt Lake Valley: the area from the base of the Oquirrh Mountains east to the Jordan River, which includes West Jordan. UGS rated it on three factors: uranium in the soil, how easily soil gas moves (permeability) and depth to groundwater (Source: UGS Special Study 91). Its finding: the highest hazard is in the western part of the valley, where soil uranium is elevated, soils are moderately permeable and groundwater is deep. The lowest is in the north and along the Jordan River, where groundwater is shallow (Source: UGS Special Study 91).
That's a planning map of potential, not a measurement of any house. UGS itself says homeowners should test (Source: Utah Geological Survey).

West Jordan is a 1980s–2000s city: 42% of homes were built from 1980 to 1999 and 38% since 2000, and the median year is 1995 (Source: U.S. Census ACS). You'll find full basements, split-levels and slab-on-grade homes on the same street. That mix matters:
- Split-level and multi-level homes may have slab sections at different heights, sometimes needing more than one suction point. Suction points and cost.
- Homes with a sump pit may be able to use it as the suction point (Source: EPA). Sump-pit suction.
Cost in West Jordan
No West Jordan–specific price data yet. Utah's typical figure is about $1,800–$2,000 (Source: Utah DEQ). Split-levels and combination foundations tend to run higher. Use the estimator, and get written bids from licensed contractors. Ask whether a city permit is needed and included.
