Question

Literature review ganges water pollution level monitoring project

Answer 1

Answer:

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. Plastic use prevents water from going underground. As a result, the water level below the ground has reduced and now it has reduced to a scary situation. 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 groundwater.

answer:

The undesirable change in physico-chemical characteristics of water bodies is water

pollution. Today pollution of water resources has been most exploited due to increasing

population, industrialization, urbanization, increasing living standards and board spheres of

human activities. Good quality water is inadequate even for the normal living and is getting

polluted due to industrial discharges including those of paper, textiles, rayon, fertilizers,

pesticides, detergents, antibiotics, oil refineries, tannery and photo films.

Consequently water resources of highly industrialized cities in India (Such as Mumbai,

Kolkata, Delhi, Kanpur, Pune, Agra, Durgapur etc.) have been chronically polluted. Thus,

efforts are mainly concentrated to enact laws to check these practices to control water

pollution.

Major Indian rivers, such as Ganga, Yamuna, Tapti, Narmada, Sone, Chambal, Daha,

Damodar, Krishna, Cauvery and other rivers are severely polluted. Systematic observations at

different distances of these rivers are being made by several researchers time to time.
