Water Systems
Fact:  There is the same amount of water on Earth today as there was 3 billion years ago.

Fact:  About 70% of the earth's surface is covered in water, and  97% of that is salty or undrinkable.

Fact:  Three percent of the water on Earth is freshwater, but 2.997 % of that is locked up in icebergs and glaciers.

Fact:  Only 0.003% of the world's water is available to us for all our needs and uses.

Fact:  Of the total world's freshwater supply, over two thirds is found underground.

Fact:  There is a limited supply of fresh water in the world and about 25% of this fresh water is in the lakes and rivers of Canada.    Water is our precious resource.

So, what do people do???

Fact:  On average, 18% of Canada's urban population live in municipalities that do not provide sewage treatment.

Fact:  Toilets (while consuming nearly one quarter of our municipal water supply) use over 40% more water than needed.

Fact:  Many homes lose more water from leaky taps than they need for cooking and drinking.

Fact:  A single lawn sprinkler spraying 19 litres per minute uses 50% more water in just one hour than a combination of ten toilet flushes, two 5 minute showers, two dishwasher loads, and a full load of clothes.

Fact:  One litre of oil can contaminate up to 2 million litres of water.

Fact:  Landfills, leaking gasoline storage tanks, leaking septic tanks, accidental spills and farm land treated with pesticides and fertilizers are a few examples of how we are treating our precious groundwater.

me well.
Now it is time to take a look, in detail, at the earth's water systems!
