Alkalinity: The Alkalinity or the buffering capacity of a stream refers to how well it can neutralize ,acidic, pollution and resist changes in pH. Alkalinity measures the amount of ,alkaline, compounds in the water, such as carbonates, bicarbonates and hydroxides. These compounds are natural buffers that can remove excess hydrogen, or H+, ions.
