Water qualityDefinition (http://en.wikipedia.org/wiki/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. (Wikipedia) Preferred Units: N/A Scope Note:
