How does acid rain affect soils that are already acidic ?
This is exactly the case in New England. The parent material for the soils in that region is granite, a rock containing few alkaline 4 elements to neutralize soil acidity. Runoff from frozen soil during Spring snowmelt provides little opportunity for the meager capacity of the soil to neutralize Winter’s accumulated acidity. Acidic runoff washes into lakes and streams where it kills aquatic flora and fauna. The most severe ecological damage from acid rain 1 occurs in aquatic ecosystems and damage to foliage in ecosystems exposed to acidic fog.
