Water Quality

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:

    It is moot whether there be divinities
    As I finish this play by Webster:
    The street-cars are still running however
    And the katharsis fades in the warm water of a yawn.
    Allen Tate (1899–1979)

    I am not naturally ... “A bag of wind”; yet ... I mean deliberately and decidedly “to cut” in future all my old ideas on this head. I don’t think modesty “pays.” It is a good quality in a family, it is a domestic virtue, it makes a home happy after you have got a home, but it is not potent in getting homes. It is not a money-maker, neither is it lucky in gaining a reputation. I am of the impression that gaseous bodies do better.
    Rutherford Birchard Hayes (1822–1893)
