Polluted or
Healthy?
Sometimes it is easy
to tell…sometimes it
is harder
How does pollution get into the
water?
• Heavy rain washes things from the land
into places like lakes, rivers and oceans.
• We call this stormwater.

How can we keep our water and air
healthy?

• Throw trash away properly
• Ride a bicycle instead of driving a car
• Use solar energy instead of energy from
power plants
