1. Pollution and Water Stewardship

2. Pollution types- point source
Point source pollution = source of pollution is known and identifiable.
Real life examples= toxic effluents from a factory, agricultural run-off.
Effluents= chemicals or fluid that flows out

3. Pollution types- nonpoint source
Nonpoint source pollution = source of pollution is too widespread to identify or blame
Real life examples= urban run-off from roads and parking lots, neighborhood run-off from storm drains, sewage leaks such as pig waste or pesticides, and overfishing from fisheries.

4. Ways to correct- nature
Water is recycled through the water cycle. Water is filtered through percolation. This method is mostly effective but time consuming.

5. Ways to correct- Legislation
There are many laws that impact water quality on federal, state and municipal books.
Two most important-
Clean Water Act (1972)
and
Safe Drinking Act (1974)

6. Ways to correct- Legislation
Clean Water Act (1972)= a law that works to correct toxic effluents from industries through establishing safety standards, clean-up guidelines, and penalties.
What kind of pollution does it mostly correct? Point source pollution!

7. Ways to correct- Legislation
Safe Drinking Act (1974)- a law that works to provide standards for what is safe water to drink.
What vocab word does the Safe Drinking Act protect?

8. Ways to correct-stewardship
Stewardship = to protect the environment
Ways to be a good steward:
Conservation of resources
Clean up of polluted areas
Establishment of nature preserves and wildlife areas

9. Water Treatment
Water treatment plants = where they filter, remove, and chemically sanitize water to provide drinkable water.
