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:
“The water never formed to mind or voice,
Like a body wholly body, fluttering
Its empty sleeves; and yet its mimic motion
Made constant cry,”
—Wallace Stevens (1879–1955)
“We’re headed for collapse, if you want my opinion, Missy. I can see it in the fallin’ off of the quality of vagrants. There was a time you could find real good company in almost any jungle you’d pick, men who could talk, men who’d read a book now and then; and now, what do you find, a lot of dirty little guttersnipes no decent tramp would want to associate with.
Well, it’s been that way all through history.”
—John Dos Passos (1896–1970)
