What Causes Water Pollution?

Water pollution can be caused by stormwater collecting chemicals and materials that are carried into stormwater drains and into our waterways, septic tank leaks, grey water, sewerage and illegal disposal of chemicals, rubbish and other toxic substances into stormwater drains and waterways.

The effects of water pollution can be devastating to our environment and can last for many years. They can also have a significant effect on our health. Some of the pollutants that can enter our waterways through stormwater drains are discarded litter like cigarette butts, empty cans, plastic wrappers that can take many years to decompose, garden waste such as grass clippings, leaves and branches, animal waste, garden pesticides and fertilisers, detergents, motor oil, concrete, oil, grease and paint. Even the smallest amount can do a great deal of damage. According to the Environment Protection Authority (EPA) Victoria just 1 litre of motor oil is enough to make an Olympic size swimming pool (1 million litres of water) unsafe for plants or animals.

Visit the EPA Victoria website for a list of the different types and causes of stormwater pollution.
