Riparian Buffers & Pollution

LEQ:

• In what ways can humans help maintain a clean water supply?

Riparian Buffers!

• WHAT? Strips of vegetation (trees/plants) next to streams and rivers

Why??

• 1. Limits flow of pollution into water

2. Slows floodwater

3. Provides shade; cools the water

4. Limits mud and sediment from flowing into water preventing erosion.

5. Provides habitat for animals

No Riparian Buffer

Riparian Buffers Rule!

Lets Review

1. Fold paper into 4.

2. In each box, draw a quick symbol/picture to represent what a riparian buffer is or does.

Water Pollution

When chemicals or other

harmful substances enter our

water supply

Point Source Pollution• An identifiable source of pollution that directly enters the water

• Ex. Pollution being dumped into a river via a pipe from a factory

• Ex. Directly dumping trash into a river

Non Point Source Pollution

• Pollution that INDIRECTLY enters our water through run off

• Spread out over large areas• Example: Fertilizers from lawn washed into a

river with the rain

Point or Non point?

• Ask yourself:

Did this enter the water by runoff?

Yes? Non point No? Point

Label your paper 1-7.

Hint! Ask yourself: Did this enter the water by runoff?

1. Point or Non Point?? WHY?

2. Point or Non Point? Why?

3. Point or Non Point? Why?

4. Point or Non Point? Why?

5. Point or Non Point? Why?

6. Point or Non Point? Why?
