Water quality refers to the chemical, physical and biological characteristics of water. It is a measure of the condition of water relative to the requirements of one or more biotic species and or to any human need or purpose. It is most frequently used by reference to a set of standards against which compliance can be assessed. The most common standards used to assess water quality relate to health of ecosystems, safety of human contact and drinking water.

Famous quotes containing the words water and/or quality:
“We were uncertain whether the water floated the land, or the land held the water in its bosom. It was such a season, in short, as that in which one of our Concord poets sailed on its stream, and sung its quiet glories.”
—Henry David Thoreau (1817–1862)
“If behind the erratic gunfire of the press the author felt that there was another kind of criticism, the opinion of people reading for the love of reading, slowly and unprofessionally, and judging with great sympathy and yet with great severity, might this not improve the quality of his work? And if by our means books were to become stronger, richer, and more varied, that would be an end worth reaching.”
—Virginia Woolf (1882–1941)
