The Amargosa Desert Research Site (ADRS), in the northern Mojave Desert, is about 20 km east of Death Valley National Park. Recognizing the paucity of information on unsaturated-zone hydrology in arid regions, the USGS, in 1983, established the ADRS through agreements with the Bureau of Land Management (BLM) and the State of Nevada. The ADRS serves as a field laboratory for the study of arid-land...

In 1976, the U.S. Geological Survey (USGS) began studies of unsaturated zone hydrology at a site in the Amargosa Desert near Beatty, Nevada, as part of the USGS Low-Level Radioactive Waste Program. The site is near disposal trenches for civilian waste.Over the years, USGS investigations at the Amargosa Desert Research Site (ADRS) have provided long-term "benchmark" information about the hydraulic...

The Black Mountain Industrial (BMI) complex, in Henderson, Nevada, has been the site of industrial chemical production since 1942. Perchlorate contaminants, from activities at BMI, have moved through the groundwater system and have been discovered in the Las Vegas Wash, prompting water resource investigations and groundwater treatment by the Nevada Division of Environmental Protection (NDEP). The...
