United StatesPhysical EnvironmentAverage acidity of precipitation in the United States. Lower pH values represent greater acidity.
Geosystems: Intro to Physical Geography
A map shows the p H levels of acid rain in the U.S. States like Ohio and Pennsylvania have the lowest p H levels (4.50 to 4.59 p H, black). States like Arizona and Nevada show the highest p H levels (greater than or equals 5.30 p H, light yellow).
