Surface brine deposits are exploited using solar evap- oration ponds to concentrate and precipitate the potash. The evaporation ponds are extensive, with some operations covering in excess of 90 square kilo- meters of land area to produce around 8 million tonnes of potash ore per year. Conventional mechanized underground mining oper- ations are the most widely used method for the extraction of potash ore. A variety of mining tech- niques and equipment may be employed depending on factors such as: the orebody depth, geometry, thickness and consistency, the geological and geotech- nical conditions of the ore and surrounding rock, and the presence of overlying aquifers. Methods in wide- spread use include variations of room. | Arizona s Children and the Environment A Summary of the Primary Environmental Health Factors Affecting Arizona s Children Arizona Department of Health Services Bureau of Epidemiology and Disease Control Office of Environmental Health December 2003 Arizona Department of Health Services Arizona s Children and the Environment A Summary of the Primary Environmental Health Factors Affecting Arizona s Children ARIZONA DEPARTMENT OF HEALTH SERVICES Division of Public Health Services Bureau of Epidemiology and Disease Control Office of Environmental Health 150 N. 18th Avenue Suite 430 Phoenix Arizona 85007-3245 602-367-6412 1-800-367-6412 December 2003 Executive Summary In accordance with the Governor s Children s Environmental Health Project initiative the Arizona Department of Health Services Office of Environmental Health assessed the environmental factors that most affect Arizona s children.
