According to the Department of Oceanography at Texas A&M University, acid rain falls primarily near power plants. The Northeastern United States is the most affected area. Little Echo Pond in Franklin, N.Y. is one of the most acidic lakes in the United States with a pH of 4.2.
Acid rain is described as any kind of wet deposition of acid (nitric and sulfuric) in the form of precipitation, such as rain, snow or fog. Rain is called acidic when it falls with a pH rate of less than 5.0. Acid rain can occur anywhere the release rates of burning fossil fuels, sulfur dioxide (SO2) and nitrogen oxides (NOx) are very high.
