Water quality is the physical, chemical and biological characterisitics of water. The Clean Water Act requires each jurisidiction to submit biennial reports on water quality in their respective area. [ [ This Act is the primary federal law governing water pollution. Maximum contaminant levels are standards set by the EPA for drinking water quality. It is expressed as a concentration in milligrams or micrograms in a liter of water. It is determined by how much of the contaminant can be present, with no ill effects on health. Pollutants include point sources from a stationary, identifiable source such as a pipe or a sewage treatment plant. It includes storm sewers, construction sites, etc. Non-point sources include pollutants that contaminate the water from various sources that accumulate- example, leaching of nitrogen compounds from fertilizing farmlands.
