Distribution of uranium in rocks and radon levels in water in the San Carlos-Safford-Duncan Nonpoint-Source Management Zone

Dataset Identification:

Resource Abstract:
As part of a study of potential non-point-source impacts on water quality, this reportdiscusses the nature and distribution ofuranium and radon in rocks, sediments, soils, and water in the San Carlos-Safford-Duncan Nonpoint-Source Management Zone (Figure 1). This study relies on previously published information, and for much of the Management Zone, this information is not detailed, or is not available.Uranium is a naturally occurring element, found in all rocks and soils, as well as in allnatural surface and groundwaters. Average values for typical crustal rocks are 4.4 ppm forgranite, 0.8 ppm in basalt, and 3.8 ppm in shale (Brownlow, 1979, p. 43). The range of uraniumconcentrations within each rock type commonly varies by factors of 2 to 10.Granites in Arizona, for example, have background levels of uranium ranging from 1.17ppm in the Wilderness Granite, Santa Catalina Mountains, to 10 ppm in the Stronghold Granite in the Dragoon Mountains, and up to 51 ppm in the Lawler Peak Granite in Yavapai County (Duncan and Spencer, 1993b).Radon is a naturally occurring gas produced from the radioactive decay ofuranium.222Radon, the isotope of interest, is a daughter of 238U (via 226Ra). 222 Radon decays with a half life of 3.82 days, emitting an alpha particle.Radon is highly soluble in water, and consequently is found in all natural waters. Radonmay degas from domestic water, accounting for some ofthe indoor radon found in buildings. TheU.S. Environmental Protection Agency has proposed, but not yet enforced, a limit of 300picocuries per liter (PCiIl) for radon in water.( 10 pages, 3 map sheets)
