The amount of contaminant load that can be discharged to a specific waterbody without exceeding water quality standards or criteria. Assimilative capacity is used to define the ability of a waterbody to naturally absorb and use a discharged substance without impairing water quality or harming aquatic life.
Natural ability of soil and water to use and decompose potential pollutants without harmful effects to the environment.
The ability of a natural body of water to receive wastewaters or toxic materials without harmful effects and without damage to aquatic life.
