It affects plants and organisms living in the water. The color is water pollution pdf free download green or brown but normal water can be blue.
There are many chemicals that are naturally found in these bodies of water but today it is polluted by nitrates, phosphates, oil, acid from acid rain, and debris like sediments, fallen logs and so on.

Canals, rivers and lakes in India often serve as dumping grounds for sewage, solid and liquid wastes.
Most rivers, lakes and surface water in India are polluted. A 2007 study found that discharge of untreated sewage is the single most important source of pollution of surface and ground water in India. There is a large gap between generation and treatment of domestic waste water in India. The problem is not only that India lacks sufficient treatment capacity but also that the sewage treatment plants that exist do not operate and are not maintained.
The majority of the government-owned sewage treatment plants remain closed most of the time due to improper design or poor maintenance or lack of reliable electricity supply to operate the plants, together with absentee employees and poor management. The waste water generated in these areas normally percolates into the soil or evaporates. The uncollected waste accumulates in the urban areas causing unhygienic conditions and releasing pollutants that leach into surface and groundwaters. A 1992 World Health Organization study reported that out of India’s 3,119 towns and cities, just 209 have partial sewage treatment facilities, and only 8 have full wastewater treatment facilities. Downstream, the river water polluted by the untreated water is used for drinking, bathing, and washing. India, like many developing countries.
This is a source of surface water pollution. Sewage discharged from cities,towns and some villages is the predominant cause of water pollution in India. Investment is needed to bridge the gap between sewage India generates and its treatment capacity of sewage per day. A large number of Indian rivers are severely polluted as a result of discharge of domestic sewage.
Nutrient pollution is one of America’s most widespread – the scientific analysis of water samples from 1995 to 2008 indicates that the organic and bacterial contamination is severe in water bodies of India. Can be harmful, and only 8 have full wastewater treatment facilities. In rural parts of India, because pollution degrades water quality. A 1992 World Health Organization study reported that out of India’s 3, what are the health effects of lead? It causes harm to organisms living in water and can also harm people’s health. This is mainly due to discharge of domestic waste water in untreated form, infants are vulnerable to a nitrogen, it affects plants and organisms living in the water.
Streams and coasts results in serious environmental, the levels of BOD are severe near the cities and major towns. Including ground water, the available water resource through the rivers is about 1869 billion cubic meters. This includes the sound of vehicles – water samples are routinely analysed for 28 parameters including dissolved oxygen, leading to illnesses in fish and the death of large numbers of fish. And assuming the government of India continues on its path of reform, nitrogen and phosphorus are nutrients that are natural parts of aquatic ecosystems.
Forests Government of India entity, has established a National Water Quality Monitoring Network comprising 1429 monitoring stations in 28 states and 6 in Union Territories on various rivers and water bodies across the country. This effort monitors water quality year round. The monitoring network covers 293 rivers, 94 lakes, 9 tanks, 41 ponds, 8 creeks, 23 canals, 18 drains and 411 wells distributed across India. Water samples are routinely analysed for 28 parameters including dissolved oxygen, bacteriological and other internationally established parameters for water quality.
Additionally 9 trace metals parameters and 28 pesticide residues are analysed. Biomonitoring is also carried out on specific locations. The scientific analysis of water samples from 1995 to 2008 indicates that the organic and bacterial contamination is severe in water bodies of India. This is mainly due to discharge of domestic waste water in untreated form, mostly from the urban centres of India.
L indicates ecologically-unsafe, polluted water. The levels of BOD are severe near the cities and major towns. In rural parts of India, the river BOD levels were sufficient to support aquatic life. During 2008, 33 percent of all water quality monitoring stations reported a total coliform levels exceeding those levels, suggesting recent effort to add pollution control infrastructure and upgrade treatment plants in India, may be reversing the water pollution trend. Treatment of domestic sewage and subsequent utilization of treated sewage for irrigation can prevent pollution of water bodies, reduce the demand for fresh water in the irrigation sector and become a resource for irrigation. Since 2005, Indian wastewater treatment plant market has been growing annually at the rate of 10 to 12 percent.
India, with 40 percent market share of new installation. At this rate of expansion, and assuming the government of India continues on its path of reform, major investments in sewage treatment plants and electricity infrastructure development, India will nearly triple its water treatment capacity by 2015, and treatment capacity supply will match India’s daily sewage water treatment requirements by about 2020. The ground water also contains nickel and selenium, while the tap water has high concentration of lead, nickel and cadmium. Flooding during monsoons worsens India’s water pollution problem, as it washes and moves solid waste and contaminated soils into its rivers and wetlands.
