Question

- Read the passage given below and answer the questions that follow.
1. Water pollution is a major environmental issue in India. The largest source of water pollution
India is untreated sewerage. Other sources of pollution include agricultural runoff and unregulated
small scale industry. Most rivers, lakes and surface water in India are polluted. A 2007 study finds
that discharge of untreated sewage is the single most important cause for pollution of surface
and groundwater in India. There is a large gap between generation and treatment of domestic
wastewater 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 wastewater generated in these areas normally
percolates in the soil or evaporates. The uncollected wastes accumulate in the urban areas cause
unhygienic conditions and release pollutants that leaches to surface and groundwater.
