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.
