ASSIMILATIVE CAPACITY

The capacity of natural water to receive wastewaters or toxic materials without negative effects and without damage to aquatic life or humans who consume the water. In other words, assimilative capacity describes the capacity of a water body’s ability in cleaning itself. In order to prevent the concentration of dissolved oxygen to go down below levels required to provide a safeguard for the organisms within the body of water, the assimilative capacity must not be exceeded.
