What is meant by "water quality?"

Water quality describes the condition of water; determined by gathering information on chemical, physical and biological characteristics, usually for its suitability for drinking, irrigation, bathing and effluent purposes. Safe water should contain no chemical or radioactive substances, be free from disease-causing organisms and be stable in terms of corrosion and scaling. Water quality is measured by several factors including; concentration of dissolved oxygen, bacteria levels, salinity (amount of salt), turbidity (amount of material suspended), the concentration of microscopic algae, the quantity of pesticides, herbicides, heavy metals and other contaminants. Although scientific analysis is used to define water quality, it is not to say that the water quality is “good” or “bad”. The determination is made relative to the purpose of the water i.e. drinking, swimming, wastewater etc. Poor water quality can pose a health risk to people, as well as flora and fauna in the ecosystems.
