The presence of certain naturally occurring elements, such as arsenic, asbestos, mercury, and uranium can make exposure to the rocks that contain them hazardous. The Washington Geological Survey provides maps and geologic information on minerals related to environmental and public health issues. Much of WGS's information on hazardous minerals shows locations of historic mines
