The Atlanta-Sandy Springs-Marietta, GA metropolitan area, also called Metro Atlanta, is made up of 28 counties in north Georgia. Its population of 5.4 million is spread out over a relatively large land area of 8,376 square miles. Although it has the ninth largest population of U.S. metropolitan areas, it is one of the less densely populated large metropolitan areas in the United States.
Most of the Metro Atlanta area lies in the Chattahoochee River basin. The Chattahoochee River feeds Lake Lanier, the main source of drinking water for Metro Atlanta.
The main industrial activities in Metro Atlanta include automobile and aircraft manufacturing, primary metals, food and beverage processing, textiles, printing and publishing, chemical manufacturing, and telecommunications hardware. In addition, the metropolitan area generates significant amounts of electric power, primarily from coal-fired plants.
In the Atlanta metropolitan area, electric utilities had the largest total disposal or other releases for 2011. Four electric utilities reported 84% of the total on-site disposal or other releases. They also accounted for 85% of total air releases, mainly hydrochloric and sulfuric acids, and 95% of total on-site land disposal or other releases, 41% of which was barium and its compounds. The food products industry reported 52% of total surface water discharges, primarily as nitrate compounds. The primary metals sector (such as aluminum extruded product and copper wire manufacturing in this region) had the second largest total disposal or other releases due to its off-site transfers to disposal.
