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:
“What a dissimilarity we see in walking, swimming, and flying. And yet it is one and the same motion: it is just that the load- bearing capacity of the earth differs from that of the water, and that that of the water differs from that of the air! Thus we should also learn to fly as thinkers—and not imagine that we are thereby becoming idle dreamers!”
—Friedrich Nietzsche (1844–1900)
“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)
