water quality
How clean H2O
Water quality measures how suitable water is for a particular use—drinking, swimming, supporting aquatic life, irrigation.
It depends on physical, chemical, and biological characteristics: temperature, pH, dissolved oxygen, contaminants, bacteria levels.
The EPA sets water quality standards for public drinking supplies.
Poor water quality can result from pollution, agricultural runoff, or natural mineral content.
