Total phosphorus

Overview

Phosphorus is a nutrient necessary for growth and reproduction. Large inputs of nitrogen and phosphorus compounds to the aquatic environment can cause excessive algal growth. When algal blooms die, concentrations of dissolved oxygen can become depleted, which can stress aquatic organisms and may cause taste-and-odor problems in water supplies.
