Quality of Water

How are water quality standards determined? Water quality is determined by three major classes that are biological, chemical, and physical. The biological class has to do with the organisms that are living in the water and how many organisms that there are. Some of the organisms that live in the water have certain physical and chemical changes that they need to stay away from the pollution in the air. If the organisms are not used to having the air pollution near them then that means that the water is good quality water. The chemical class has to do with how the water tastes, feels, smells and looks. By using chemical measurements then people can figure out how much pollution is in the water and shows how the organisms adapt to the water. The physical class shows how the water moves and to see how the water pulls the oxygen into the water.
Distinguish between water quality criteria pollutants and maximum contaminant levels. Maximum Contaminant Level Goal (MCLG) are the levels of contaminants in drinking water, which there are no known or expected risk to health. There are several types of contaminants like: Microorganisms, Disinfectants, Disinfection Byproducts, Inorganic Chemicals, Organic Chemicals and Radionuclide’s. (http://www.antiessays.com/free-essays/330530.html) Water quality criteria pollutants help keep the organisms that are in the water allow the organisms know when the water is not safe for them to be living in the water. The levels of contaminants allow the organisms to understand that they can not live in a place that the pollution is not supposed to be in the water already.
