Online Files for Acid Deposition Sensitivity Map

The following digital product represents the Acid Deposition
Sensitivity of the Southern Appalachian Assessment Area. Areas
having various susceptibilities to acid deposition from air
pollution are designated on a three tier ranking in the region of
the Southern Appalachian Assessment (SAA). The assessment is being
conducted by Federal agencies that are members of the Southern
Appalachian Man and Biosphere (SAMAB) Cooperative. Sensitivities to
acid deposition, ranked high, medium, and low are assigned on the
basis of bedrock compositions and their associated soils, and their
capacities to neutralize acid precipitation.
