Pollutants And How They Get Into The Stormwater Drains, And If We Have Seen Then In Tamaki

L.I: To describe and define the water cycle in a local setting.

For this part of Te Taiao O Tamaki Water cycle, we had to do  a brainstorm about pollutants, and how they get into stormwater drains, and if we have seen them in Johnson Reserve and the Tamaki River.

How do they get into the stormwater?
What do you see in Tamaki? Johnson Reserve, Tamaki River
Rubbish such as drink can and plastic bottles/bags
If it is small enough the rain can wash it in or people shove it into stormwater drains.
Sometimes plastic / glass bottles
If the paint is still runny the rain can wash it into the drain.
Have never seen paint in river.
Food Waste
When people drop it in or leave it on the ground, and either the wind could blow the food into the drains or rain could wash it in.
