1.2.1.1 Air Capacity

Definition: The ability water resources to maintain the ecosystem in its natural, original, or current state.

This includes both man-made and naturally occurring substances found in air that interact with water and soil, each other, and biota to produce adverse or undesirable affects. This does not include waste products managed by man, which fall under Man-made Capital.
