From Fox News:
Toxic dust being blown around as a Southern California lake shrinks is pushing officials in one county to push for state and federal emergency declarations to deal with the problem.
The Salton Sea is shrinking because water that would normally flow to it is being diverted to cities, the Desert Sun reports. As it shrinks, contaminants and caustic impurities from decades of past military testing and agricultural runoff have created the perfect storm for dangerous dust pollution. The water diversion had been expected for 14 years, yet state and federal officials have yet to agree on a plan for the lake.
