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:
“Man is but a reed, the feeblest one in nature; but he is a thinking reed. The entire universe need not arm itself to crush him—a vapor, a drop of water suffices to kill him. But if the universe were to crush him, man would still be nobler than that which killed him, because he knows that he dies and the advantage which the universe has over him; the universe knows nothing of this.”
—Blaise Pascal (1623–1662)
“What was it that drove these thousands into the arms of his art—what but the blissfully sensuous, searing, sense-consuming, intoxicating, hypnotically caressing, heavily upholstered—in a word, the luxurious quality of his music?”
—Thomas Mann (1875–1955)
