Water pollution in India
Industrial wastewater treatment. Depending on the type of assessment, the organisms may be identified for biosurveys population counts and returned to the water body, or they may be dissected for bioassays to determine toxicity. Common physical tests of water include temperature, solids concentrations e. High concentrations of naturally occurring substances can have negative impacts on aquatic flora and fauna.
Canals, rivers and lakes in India often serve as dumping grounds for sewage, solid and liquid wastes. Water pollution in India is mainly due to untreated wastewater discharge into rivers. There is a large gap between generation and treatment of domestic waste water in India. In other projects Wikimedia Commons. Resources in your library Resources in other libraries.
The distinction of point vs. Interactions between groundwater and surface water are complex. Water portal Sustainable development portal Environment portal. Story of a river being poisoned to death. Pest Control and Pesticide Safety for Consumers.
Stormwater Best Management Practice. For microbial testing of drinking water, see Bacteriological water analysis. Oxygen -depleting substances may be natural materials such as plant matter e. Water pollution is a major global problem. Marine pollution and nutrient pollution are subsets of water pollution.
Library resources about Water pollution. Biomonitoring is also carried out on specific locations. All plants and organisms living in or being exposed to polluted water bodies can be impacted.
One common path of entry by contaminants to the sea are rivers. Pollution prevention practices include low-impact development techniques, installation of green roofs and improved chemical handling e. Water pollution is a major environmental issue in India. Eutrophication is an increase in the concentration of chemical nutrients in an ecosystem to an extent that increases the primary productivity of the ecosystem. It has been suggested that water pollution is the leading worldwide cause of death and diseases.
Interdisciplinary Environmental Review. Royal Society of Chemistry.
Agricultural wastewater treatment. Surface water pollution includes pollution of rivers, lakes and oceans. In urban areas of developed countries, municipal wastewater or sewage is typically treated by centralized sewage treatment plants.
Thermal pollution can also be caused by the release of very cold water from the base of reservoirs into warmer rivers. Deuterium-depleted Semiheavy Heavy Tritiated Hydronium.

Applied and Environmental Microbiology. Such organisms can be monitored for changes biochemical, physiological, or behavioral that may indicate a problem within their ecosystem.
Sampling of water for physical or chemical testing can be done by several methods, depending on the accuracy needed and the characteristics of the contaminant. Retention basins tend to be less effective at reducing temperature, as the water may be heated by the sun before being discharged to a receiving stream. Water Pollution - Causes, Effects and Control. This type of pollution is often the cumulative effect of small amounts of contaminants gathered from a large area. Agricultural wastewater treatment for farms, games tm magazine pdf and erosion control from construction sites can also help prevent water pollution.
Surface water and groundwater have often been studied and managed as separate resources even though they are interrelated. These are sources of water pollution, as illustrated in Tamil Nadu above and West Bengal below.
Water is typically referred to as polluted when it is impaired by anthropogenic contaminants. The annual average precipitation in India is about billion cubic metres. Many contamination events are sharply restricted in time, most commonly in association with rain events. Water pollution can be grouped into surface water pollution. The scientific analysis of water samples from to indicates that the organic and bacterial contamination is severe in water bodies of India.
World Health Organization. The ground water also contains nickel and selenium, while the tap water has high concentration of lead, nickel and cadmium. Most rivers, lakes and surface water in India are polluted. Outline Data Model Properties. Effective control of urban runoff involves reducing the velocity and flow of storm water, as well as reducing pollutant discharges.
Industries that generate wastewater with high concentrations of organic matter e. This is mainly due to discharge of domestic waste water in untreated form, mostly from the urban centres of India. Local governments use a variety of storm water management techniques to reduce the effects of urban runoff.
Green Infrastructure Case Studies Report. Non-point sources are more diffuse, such as agricultural runoff. Book Category Asia portal. They are any biological species or group of species whose function, population, or status can reveal what degree of ecosystem or environmental integrity is present. Point source water pollution refers to contaminants that enter a waterway from a single, identifiable source, such as a pipe or ditch.
