On Jan. 27, the Bureau of Land Management Las Vegas Field Office announced the results of a dust emissions study for the Nellis Dunes Recreation Area. This study, conducted as part of a regulatory dust mitigation plan by the University of Nevada, Las Vegas, identified elevated levels of naturally-occurring arsenic and palygorskite, a mineral that is similar to asbestos. Both substances are naturally occurring throughout Nevada and other parts of the United States, and it is not yet known if they pose any health risk to recreational and other users of the NDRA. According to the BLM, a Human Health Risk Assessment will be conducted over the next three years to determine whether these elevated levels of arsenic and palygorskite pose a health risk, if any, to people who use the NDRA.
