Water quality refers to the chemical , physical , biological and radiological characteristics of water. This is a measure of the state of water in relation to the requirements of one or more types of biotic , or to any human need or purpose. Most often , it is used with reference to a set of standards by which compliance can usually be assessed by water purification. The most common standards used to assess water quality relate to ecosystem health , human contact safety and drinking water. Water quality has a huge impact on water supply and often determines supply options. Standards When setting standards , agencies make political and technical/scientific decisions based on how water will be used. In the case of natural reservoirs , they also make some reasonable assessments of pristine conditions. Natural reservoirs will vary depending on the state of the environment. Environmental scientists are working to understand how these systems function , which in turn helps to determine the sources and fate of pollutants. Environmental lawyers and policy makers are working to define legislation with the intention of supporting water in the proper quality for its identified use. The vast majority of surface water on Earth is neither drinking nor toxic. This remains true when seawater in the oceans (which is too salty to drink) is not taken into account. Another common perception of water quality is a simple property that tells whether water is contaminated or not. In fact , water quality is a complex topic , in part because water is a complex environment inextricably linked to the Earth's ecology. Industrial and commercial activities (e.g. manufacturing , mining , construction , transport) are a major cause of water pollution , as well as runoff from agricultural areas , urban runoff and discharge of treated and untreated sewage. Water quality options are defined by purpose. Work in water quality tends to focus on water that is treated for human consumption , industrial use or in the environment.

The U.S. Environmental Protection Agency ( EPA) limits the amount of some contaminants in tap water provided by U.S. public water systems. The Safe Drinking Water Act allows the EPA to issue two types of standards: primary standards for regulating substances that potentially affect human health ; Secondary standards prescribe aesthetic qualities that affect taste , smell or appearance. U.S. Food and Drug Administration ( FDA) rules impose restrictions on pollutants in bottled water. Drinking water , including bottled water , can reasonably be expected to contain at least a small amount of some contaminants. The presence of these pollutants does not necessarily indicate that water poses a health risk. In urbanized areas around the world , water purification technology is used in municipal water systems to remove pollutants from water sources (surface water or groundwater) before it is distributed to homes , businesses , schools and other recipients.
