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:

    The clock runs down
    timeless and still.
    The days and nights turn hours to years
    and water in a gutter marks the circle of another world
    hating, resentful, and afraid
    stagnant, and green, and full of slimy things.
    Margaret Abigail Walker (b. 1915)

    It passes, and we stay:

    A quality of loss
    Affecting our content,
    As trade had suddenly encroached
    Upon a sacrament.
    Emily Dickinson (1830–1886)
