Alabama’s Department of Conservation and Natural Resources is responsible for control of air, water, and land pollution. It also deals with matters such as soil conservation and forest management.
Air quality in most of Alabama is generally excellent. However, the federal standard for ozone is sometimes exceeded in the Birmingham metropolitan area. Air pollution problems include acid rain and toxic air pollutants such as heavy metals (lead, cadmium, mercury) and volatile organic chemicals. Most of the sulfur and nitrogen emissions that cause acid rain come from electric utilities. Alabama has been a major importer of hazardous waste, most of which has been sent to a commercial disposal facility near Emelle. A 1989 ban on hazardous waste imported from states that were unwilling or unable to undertake disposal programs was overturned in the early 1990s. In 2008 there were 13 hazardous waste sites on a national priority list for cleanup due to their severity or proximity to people. The state made progress in efforts to reduce pollution; in the period 1995–2000 it reduced the amount of toxic chemicals discharged into the environment by 29 percent.
Most other states, however, achieved far more dramatic reductions than Alabama’s. Groundwater is the source of drinking water for almost half the population and is an important source of water for agriculture and industry. Much of Alabama’s groundwater is contaminated to a limited, and not unhealthful, extent. Contaminants include organic chemicals, nitrates, fluorides, brine and salt, metals, radioactive materials, and pesticides. The sources of contamination include municipal trash landfills and hazardous waste storage ponds and impoundments. "USA" © Emmanuel BUCHOT, Encarta, Wikipedia
