The following maps offer illustrations of selected environmental problems that exist in the United States. The first map displays average pH levels for rainwater across the United States. Created by the National Atmospheric Deposition, the map provides a visual representation of the correlation of acidic precipitation and coal-burning Power Plants. Acid rain can have various effects on an environment. For more information on the effects of acid rain use the following link. http://www.epa.gov/acidrain/effects/index.html
The Environmental Protection Agency created the following map which defines three zones, based on the potential for Radon accumulation in structures - radon potential increases from zone three to zone one. High levels of radon in homes have been correlated with increased likelihood of developing lung cancer. Spokane County has incidence of high levels of radon indoors, making this a point of interest for me.
The Western United States endures prevalent earthquakes, which can be easily recognized in the proceeding USGS map. Earthquakes are one of many geologic hazards, and can pose a threat to humans and human structures. As a geology student at EWU this map is of particular interest to me. Furthermore, this map can give people a general idea about the likelihood of an Earthquake in their area.
