Water Pollution

Fertilizers and

pesticides


11/33


12/33

AgricultureFertilizers and pesticides easily dissolve in water.

They enter surface water sources through rainwater and

irrigationrunoffand also percolate into the

ground to contaminate groundwater sources.

food processing industries

Increased Demand forAnimal Products

Clothes we wear dyes and bleaches

Paper, paper, paper everywhere

Leather bags and shoes

Batteries

Pharmaceuticals

Lets look around us ..

Increase demand

for goods

Increase in Population

More Industrialisation

INCREASED INDUSTRIALISATION

All these industries are highly water polluting

Increased mining for Raw Materials

The Damodar rivertravels through6 coal fields,

183 coal mines,

28 iron ore mines,

33 limestone mines,5 copper ore mines,

84 mica mines andNumerous graphite, silver

and uranium extracting units.

Water in this river is polluted beyond repair

Mining is a highly polluting industry

Increased industrialization results in

Waste dumpedin surface water bodies

Waste dumped in open landfills toxic materials leach into

soil and groundwater

Waste burnt air pollutants dissolve in rainwater and

pollute surface water sources or seep into ground water aquifers

Lakes, tanks, and ponds being destroyed. Land filled for constructionpurposes.

Unsustainable extraction of groundwaterin urban areas, affecting

groundwater quality.

Receive sewage that cannot be handled by sewage

treatment plants.

Disposal of solid and liquid wastesabove or into groundwater aquifers.

If you had a bottle of life-preserving fluid onwhich your life depended, would you pour into it

all your sewage and rubbish, along with anyother poisonous chemicals you could find? Andyet, that is exactly what we are doing to our

water supplyall over the world.

A game to check how much you have learnt

PlayLINK TO THE GAME


27/33

Divide the class into 5 teams.

Team A selects 2 people who will guess theanswer.

These 2 people turn their face to the wall orgo out of the room, so that they cant see

the clue.

Play


28/33

Team A has to act out the clue for the 2

guessers.Either all members of Team A can act it out

(very boisterous, but all children areinvolved) or a representative is selected to

do the acting.

The other members ofTeam A

(and the rest of the class) see the clue.


29/33

If the guessers got the right answer in 30 secs,

they get 5 points

If the guessers get the right answer in 60 secs,

they get 3 points

OtherwiseThe chance then goes to Team B and so on.
