Harmonizing to the study published in a book. Sinha ( 1986 ), the concentration of fe is higher in deposits collected from 10 meters along the bank at Mandiri part. The concentration of all the toxic metals. E cu, zn, ni and co are higher in all the deposits collected from near the storm drain and diminishes towards mid-region of the river. The concentration of Zn is highest in the deposits collected from near the mandiri storm drain, Antaghat storm drain and Krishnaghat storm drain. The concentration of cu is highest in the deposits collected from near the Krishnaghat storm drain proposing the presence cu due to utensil work being done in Thatheri bazar and infirmary wastes besides, said study. Present state of affairs: For some clip now, this romantic position of the ganges has collided with India s inexorable worlds.

Study revealed the presence of toxic metals likea quicksilver ( 65 to 520ppb ), lead ( less than 10 to 800 ppm ), cr ( less than 10 to 200 ppm ) and nickel ( less than 10 to 130 ppm ) in the deposits. Upstream from Varanasi, one of the major pilgrims journey sites along the river, the H2O is relatively pure, holding a lowa biochemical O demandA and faecal coliform count. Surveies conducted in 1983 on H2O samples taken from the right bank of the ganga at Patna confirm thatA escheria coliA (. ), faecal streptococcus and vibrio cholerae beings die two to three times faster in the ganga than in H2O taken from the rivers Son and Gandak and from dug Wellss and tubing Wellss in the same country.

In coaction book with the State pollution Control boards of Uttar Pradesh, bihar and Bengal and the centre for survey of Man and Environment Kolkata ( Calcutta ), surveies were conducted on the sources of pollution including all human activities, land usage form and H2O quality. Harmonizing to this study sewerage of 27 category i metropoliss and towns and wastewaters from 137 major industries were the chief beginning of pollution of the river. In add-on cremation of dead human organic structures and dumping of carcases aggrevated the pollution of the river. It was Chandra ( 1981 ) who conducted surveies on the pollution position of river Ganga at Allahabad, pointed out that industries fabricating nitrogen-bearing fertilisers have important function in fouling the river water. Study carried out in 1986-87 on physico-chemical belongingss of river Ganga H2O at Buxar ( Unnao ) clearly revealed that extent of pollution varied in different seasons.
Count ranged from.0.5 ppm with maximal values during January and February. While the minimal values were recorded in monsoon. Bhargava ( 1982 ) in a study of friend entire length of the river Ganga found that quality index was far above the prescribed bound at Kanpur. He farther found that the ganga H2O was holding remarkably fast renewing capacity by conveying down. Owing to the presence of big sum of good adopted microorganism. Harmonizing to the research Ganga is rich in polymers excreted by assorted species of bacteriums. These polymers being first-class coagulators take turbidness by curdling, puting the suspended atoms at the sewerage discharge point. At the 1981 session of Indian Science congress at Varanasi, scientists expressed concern at the turning pollution in the river Ganga in presence of the so Prime minister Mrs.
( 1976 ) studied the bacteriological population of the river H2O and concluded that add-on of untreated waste and sewerage was responsible for the presence of infective beings presenting menace to the occupants of the varanasi metropolis. Hydrobiological characteristics of the river Ganga was studied by a pahwa and Mehrotra ( 1966 ). The writers studied a stretch of 1090 kilometer.

It was observed by him that the values of the most of the parametric quantities decreased during showery season while no pronounced fluctuation was observed during winters and summers. In the same twelvemonth Chakraborty. ( 1965 ) from Kanpur reported the H2O quality of Ganga. Rayon s H2O consumption point and at Golaghat and Bhairoghat pumping Stationss situated at the upstream of the river. It was concluded that the H2O quality bit by bit deteriorated as it passes from Bhairoghat pumping station to the. Rayon H2O consumption point in summers because in this stretch the river received waste waterss from figure of sewerage drains. A a twelvemonth subsequently saxena.
( 1966 ) made a systematic study of the chemical measure of Ganga at Kanpur. Harmonizing to the survey, the biological O demand,. Varied from.3ppm ( lower limit ) in winter.0ppm ( upper limit ) in summer. The chloride ranged between.2 and.7 ppm and the river was found to be alkalic in nature except in rainy season.

This self purification feature of Ganga is the key to the sanctity and holiness of its H2O. The combination of bacteriophages and big populations of people bathing in the river have seemingly produced a self-purification consequence, in which water-borne bacteriums such as dysentery and cholera are killed off, forestalling large-scale epidemics. The river besides has an unusual ability to retain dissolved. With turning civilisation and population all over how long Ganga will retain its ego purification features merely clip can judge.

A, the largest feeder to the ganga is the Ghaghara, which meets it before patna, in Bihar, bearing much of the himalayan glacier thaw from Northern Nepal. The gandak, which comes from near Katmandu, is another large himalayan feeder. Other of import rivers that merge with the ganga are the son, which originates in the hills of Madhya pradesh, the gomti which flows yesteryear Lucknow. Previous Work: A figure of probes have been carried out on the physiochemical and biological characters of the ganga.

Hundreds of the small towns and even the large metropoliss depend for their imbibing H2O on this river.

These rivers can be categorized into four groups:.rivers that flow down from the himalayas and are supplied by runing snow and glaciers. This is why these are perennial, that is, they neer dry up during the twelvemonth. The deccan Plateau rivers, which depend on rainfall for their H2O. The coastal rivers, particularly those on the west seashore, which are short and do non retain H2O throughout the twelvemonth. The rivers in the inland drainage basin of west Rajasthan, which depend on the rains. These rivers usually drain towards silt lakes or flux into the sand. River Ganga ( Ganges ) of India has been held in high regard since clip immemorial and Hindus from all over the universe cherish the thought of a holy dip in the river under the religion that by making so they will acquire rid.
Prior to this the agricultural civilizations created important environmental impairment in the signifier of dirt erosion- through deforestation and overgrazing. The environmental debasement is a by merchandise of modern civilisation. A, there has been a steady impairment in the quality of H2O of Indian rivers over several decennaries. India s 14 major, 55 child and several hundred little rivers receive 1000000s of liters of sewerage, industrial and agricultural wastes. Most of these rivers have been rendered to the degree of sewerage fluxing drains. There are serious H2O quality jobs in the metropoliss, towns and small towns utilizing these waterss. Water borne diseases are rampant, piscaries are on diminution, and even cowss are non spared from the onslaught of pollution.

All of us have seen a river big or little, either fluxing through our town, or someplace else. Rivers are nil more than surface H2O fluxing down from a higher height to a lower height due to the pull of gravitation. One river might hold its beginning in a glacier, another in a spring or a lake. Rivers carry dissolved minerals, organic compounds, little grains of sand, crushed rock, and other stuff as they flow downstream. Rivers begin as little watercourses, which grow wider mini as smaller watercourse and rivers join them along their class across the land. Finally they flow into seas or oceans. Unfortunately most of the universe s major rivers are to a great extent polluted. A, the pollution of environment is the gift of the industrial revolution.
