| WHAT CONSTITUTES “WATER QUALITY”? | ||||
“Water Quality” is a term used to describe the chemical, physical, and biological characteristics of water, usually in respect to its suitability for a particular purpose. Although scientific measurements are used to define a water's quality, it's not a simple thing to say that "this water is good," or "this water is bad." After all, water that is good enough for one thing may not be suitable for another.

POINT SOURCE a. Point source contamination can be traced to specific points of discharge such as wastewater treatment plants, industry, or livestock feeding operations. b. http://cfpub.epa.gov/npdes/ NON-POINT SOURCE a. Non point source (NPS) pollution, unlike pollution from industrial and sewage treatment plants, comes from many diffuse sources. NPS pollution is caused by rainfall or snowmelt moving over and through the ground. As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into lakes, rivers, wetlands, and even underground sources of drinking water. NATURAL BACKGROUND a. The nature of the soil type, topography or shape of the land, climate and the flow of water all effect water quality FLOW REGIME CHANGES
