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 land may vary more;
    But wherever the truth may be—
    The water comes ashore,
    And the people look at the sea.
    Robert Frost (1874–1963)

    There’s a quality of legend about freaks. Like a person in a fairy tale who stops you and demands that you answer a riddle. Most people go through life dreading they’ll have a traumatic experience. Freaks were born with their trauma. They’ve already passed their test in life. They’re aristocrats.
    Diane Arbus (1923–1971)
