what are the types of water quality?
527758
There are five water quality parameters: pH, biological oxygen demand (BOD), suspended solids (SS), dissolved oxygen (DO), and total coliform bacteria.

There are different types of pollution: water pollution, air pollution, solid waste pollution and noise pollution. All of these can be found in urban areas. The main sources of pollution are household activities, factories, agriculture and transport.

One of the most useful describes pollution in terms of its source and effects. Using this framework, the three main categories of water pollution are point-source, nonpoint-source and trans-boundary.

Water quality is measured according to many characteristics, including pH, color, taste, dissolved metals and salts, organics, radon, heavy metals and drug content. Water supply considers how accessible that water is to humans, and involves the use of pumps, pipes, taps or wells.

AQUATIC ECOSYSTEMS-FRESHWATER TYPES. The freshwater ecosystems are generally classified into two major groups as, lentic and lotic ecosystems. The term Lentic ecosystems is given to standing water bodies or still water bodies. The LENTIC Ecosystems includes all standing water bodies like Lakes, ponds, swamps or bogs.

Physical properties of water quality include temperature and turbidity. Chemical characteristics involve parameters such as pH and dissolved oxygen. ... These parameters are relevant not only to surface water studies of the ocean, lakes and rivers, but to groundwater and industrial processes as well.

Water quality. The quality of any body of surface or ground water is a function of either both natural influences and human influences. ... Drinking water quality guidelines and standards are designed to enable the provision of clean and safe water for human consumption, thereby protecting human health.

The quality of any body of surface or ground water is a function of either both natural influences and human influences. ... Globally, the most prevalent water quality problem is eutrophication, a result of high-nutrient loads (mainly phosphorus and nitrogen), which substantially impairs beneficial uses of water.

The microbiological quality of drinking-water has been implicated in the spread of important infectious and parasitic diseases such as cholera, typhoid, dysentery, hepatitis, giardiasis, guinea worm and schistosomiasis. Many other diseases are associated with water in other ways.
