2. POLLUTION
Pollution is the introduction of contaminants into the natural environment that cause adverse
change.
They are majorly divided as;
Air SoilWater

3. WATER Pollution
The water pollution is the process of contamination of water bodies such as rivers,
lakes, ponds, oceans and more .
It includes contamination by pollutants such as chemical, bacterial or particulate
that reduces the purity of the water
Types;
 Surface Water
 Marine
 Ground Water

5. India at a Glance

6807’ and 97025 East longitudes
Climate Tropical
Land Frontier 15,200 km
Coastline 7,500 km
No. of States/
UTs 29 States and 7 Union territories
Water : 4% Of world’s total

6. SURFACE or RIVER Water
Pollution
Pollution of Water or Contamination Of water either directly or indirectly due to
pollutants in river is river pollution.
Source;
 Domestic Waste: Like detergents, Sewage, Garbage, …
 Agricultural Waste: Like Fertilizer, Pesticides, …
 Industrial Waste: Like toxic Substance, grease, oil, acid, …

11. – These Are Some Of Cause or Reason….
– Industrial waste
– Improper practices in agricultural sector
– Reduction in water quantity in rivers in plains
– Social and religious practices like dumping dead bodies in water, bathing, throwing
waste in water
– Oil leaks from ships
– Acid rain
– Global warming
– Eutrophication
– Inadequate industrial treatment of wastes
– Denitrification

12. Effects
Water pollution can have some tremendously-adverse effect on the health of any and every life
Effects…
– Water becomes dangerous to drink: Humans have less safe drinking water.
– Less clean water for agriculture: we need unpolluted water to irrigate crops, too.
– Economic costs: When water has been polluted, there is money needed to purify water, remove
plastics from water bodies and so on.
– Change in water color: Polluted water becomes visibly different.
– Water-borne diseases: Living near to polluted water can put humans at risk of diseases.

13. – Fewer possibilities for leisure: Swimming, sailing, surfing and other water sports are definitely
not advised in polluted water.
– Acidic rain: When toxic gases and smoke is released from industries, cars and homes, the gases
lead to formation of acid rain. Acidic rain is a threat to human health and it also affects the living
organisms in soil.
– Genetic mutations: The genes of marine and freshwater plants and animals mutate
– Acid oceans: pollution causes the oceans to acidify.
– Algae bloom: An excess of oxygen in waters due to a change in the chemical composition causes
algae to bloom in overabundance and block out the light in pools and river.
– Damage to the ecosystems: Ecosystem is the interaction of living things, depending on each
other for life.

15.  Out of the 445 rivers surveyed, not even a quarter of them are fit for bathing.
 Indian cities generate 10 billion gallons or 38 billion litres of municipal waste water every day,
out of which only 29% of it is treated.
 The Central Pollution Control Board also stated that there were only 160 sewerage systems and
sewage treatment plants in nearly 8,000 towns surveyed in 2011.

16. SOLUTION…
– Treatment plants
– Cleaning up waterways and beaches
– Avoiding the usage of non-biodegradable material like plastic
– Being more involved in various measures pertaining to preventing water pollution.
– Avoid pouring medicine and insecticides in toilets and sinks
– Use manure instead of fertilizers
