1. We have talked about… Groundwater Surface water Watersheds

2. What can cause our supply of water to become contaminated?

3. Many things

4. Construction Sites Can produce more SEDIMENTS to wash into the waterways.

5. Lumbering Practices Can produce more SEDIMENTS to wash into the waterways.

6. Oil Refinery Can produce oil, gasoline products to wash into the waterways. Can KILL wildlife!!!

7. Gas Station Can produce oil, gasoline products to wash into the waterways.

8. Can produce oil, gasoline products to wash into the waterways. Oil drilling rigs

9. Roadways with traffic Can produce oil, gasoline products to wash into the waterways.

10. Feedlots with animal waste (animal pens) Can wash waste into streams, rivers, and lakes.

11. Human waste (not treated) Can wash waste into streams, rivers, and lakes. (if not treated)

12. Wastewater treatment plants Usually release wastewater into streams, rivers after one treatment.

13. Paper mill plants Use water in the processes of the plant. Can cause contaminants in water.

14. Food processing Plants Use water in the plant processes that can be released into streams, rivers, and lakes.

15. Mining Can release inorganic chemicals into streams, rivers, and lakes.

16. Manufacturing Plants Can release inorganic chemicals into streams, rivers, and lakes.

17. Agriculture Practices Can release excessive fertilizers into streams, rivers, and lakes.

18. Applying fertilizer to fields and then washing off. Can release excessive fertilizers into streams, rivers, and lakes.

19. Car washing Can release excessive detergents into streams, rivers, and lakes.

20. Deep Water Dams – (produce cooled water) Can cause “cooler” water into streams, rivers, and lakes which can harm wildlife.

21. Electric Producing Plants – (coal burning) Can release “heated” water into streams, rivers, and lakes which can harm wildlife.

22. Chemicals used in various plants – Burning Fossil Fuels Can cause chemicals in the air that form acid rain which harms wildlife.

23. Applying pesticides, herbicides, fungicides Can wash off into streams, rivers, and lakes.

24. Humans Impact Water Quality!
