This document discusses water pollution, its causes, and its effects. It notes that water pollution can occur in groundwater, surface water, and rainwater. The main causes of water pollution are listed as industrial waste, sewage, ocean dumping, livestock, and overpopulation. Some of the most polluted rivers in the world are identified as the Citarum in Indonesia, Ganga in India, and Buriganga in Bangladesh. The effects of river pollution include widespread loss of marine life, reduced fresh water, and increased water-borne diseases.

2. CONCEPT OF WATER POLLUTON

a waterway from a single
, identifiable source ,
such as pipe or ditch.
 Water pollution may
occurs in :-

7. DECLINE OF INDIA’S LIFELINE

8. HISTORICAL BACKGROUND
 Water and air pollution in U.S. urban areas
continued to increase well into the 20th century.
 Chicago built the first major sewage system in the
United States to treat wastewater.
 The Cuyahoga river in Cleveland,Ohio,became so
polluted that water erupted into flames first fire
occurred in 1936, when a spark from a blowtorch
ignited floating debris and oils.

9. INITIATIVES AGAINST WATER
POLLUTION
 A three day national conference on issues for optimal use
of water resources called “Jal Manthan” was held at New
Delhi from 20 to November 22, 2014.
 Special teams set up by the Ministry of Water
Resources, River Development and Ganga
Rejuvenation have started submitting their reports.
 Water (prevention and control of pollution) Act, 1974

10. MY OWN OPINION
 People should be made aware about the
hazardous effects of water pollution.
 Strict rules should be implement by
government.
 Biodegradable waste should be decomposed
properly.
 Their should be separate reservoirs for
sewage and industrial waste dumping.
