The land: Acid rain can rain down onto plants and animals, giving them chemical burns and stripping trees of leaves and bark, leaving decaying organic matter behind.
The water: Pollution in the water can cause the pH (acidity or basicness) of the water to change. A lot of organisms can't survive too much swing in either direction of the pH scale, so they will all start to die, except for a few outliers that can handle it, who's population explodes and completely take over the aquatic ecosystem.
