Different reasons
1.1 Blue water
Collectable water from rainfall.
 The water that falls on roofs and hard surfaces usually
flowing into rivers and the sea and recharging the ground
water.
In nature the global average proportion of total rainfall that is
blue water is about 40%.
Facts about Blue water
About 4,000 to 5,000 km3 are annually withdrawn from
blue water sources
On average, the rate of withdrawal of blue water has
been about two and a half times faster than the rate of
population increase during this century.
About 70 % of the total is supplied for irrigation purposes
1.2 Grey water
Water from our bathroom,
showers, washing machine,
etc.
It`s not from the toilet
It is a safe and even
benefical source of irrigation
water in a yard
1.3 Green Water
Water transferred back to the atmosphere from soils,
natural foliage and rain-fed agriculture.
 The United Nations Water Program
Climate change is significantly affecting the availability of
freshwater in many regions around the world.
2.1 Water pollution in Scotland
Pollution that affects our rivers, lochs and wetlands is often
characterised in two different forms.
Point source pollution
Diffuse source pollution
Point source pollution can come from sewage treatment
works, factories and input from fish farms.
The impacts of pollution can be a loss of biodiversity, as well as
adverse effects to our own health.
2.2 Water pollution in Germany
Quality of water: 57th place in the world
- measured lakes and rivers
- polluted due to farming and industry
Germany’s freshwater is one of the best in the world
- drinking water is one of the cleanest all over the world.
2.3 Water pollution in China
 All Chinese rivers are polluted to some degree:
Household water
Industrial water
Agricultural Water
2.4 In Estonia
Condition of water bodies
In the last decade the population has decreased 8% and in
connection with that the load of domestic wastewater discharged
into water has decreased.
Major water pollutants:
Phosphorus
Nitrogen
3.1 Developing Countries
Every day 4500 children
die, because they don`t
have clean water
One in six human have
dirty or polluted drinking
water
3.2 Diseases caused by water Pollution
Diseases:
Cholera
Typhus
Diarrhoea
Hepatitis A and E
3.3 Reasons for Disease
Climate
Bacteria
Poor water systems
Contaminated water e.g Radioactive substances In
Chernobyl.
