Abstract

Acid rain is a political problem because industrial emissions responsible for acidic precipitation cross political borders. Regions where the density of sulfur dioxide emissions was more than 1.5 tons per square kilometer in 1980 are shown in gray; states with the largest emissions are in the Midwest and along the Ohio River. The contours show the pH of precipitation; low pH means high acidity. Within the low-pH regions, lakes and streams are at highest risk of acidification where the water’s alkalinity is lowest (orange)—largely in the Adirondacks and New England. Sulfur dioxide data are from the National Acid Precipitation Assessment Program, alkalinity data from James M. Omernick of the Environmental Protection Agency and his colleagues.
