1. Chesapeake Bay and Land Use

2. Land Use Issues in Bay Watershed Herbicides and Pesticides Herbicides and Pesticides Fertilizer Fertilizer Sediment Runoff Sediment Runoff Pet Waste Pet Waste Removal of Forests Removal of Wetlands Farms Gasoline and Oil Pollution

3. Bay and River Water Quality Because things on land are easily washed into streams and rivers, our actions on land ultimately affect the Bay. Because things on land are easily washed into streams and rivers, our actions on land ultimately affect the Bay. Including sediment, pesticides, herbicides, and fertilizers Including sediment, pesticides, herbicides, and fertilizers

4. Cause of the Problem The amount of nutrients that would naturally enter the Bay would be okay, but the amount going into the Bay now has been amplified by people. When we use fertilizers, dispose of sewage, drive cars, and generate electricity, we harm the Bay.

5. Sources of Nutrient Pollution Point Sources - can be traced back to a specific area Point Sources - can be traced back to a specific area Waste water treatment plants, broken sewage pipes Waste water treatment plants, broken sewage pipes Non-Point Sources - pollution comes from large areas Farms, lawns, golf courses

6. Nitrogen Pollution Burning fossil fuels (coal, gas, or oil power plants) puts nitrogen oxide into the air Burning fossil fuels (coal, gas, or oil power plants) puts nitrogen oxide into the air Vehicle exhaust also puts nitrogen oxide into the air Vehicle exhaust also puts nitrogen oxide into the air Rain washes nitrogen out of air and into the bay Rain washes nitrogen out of air and into the bay

7. What Needs To Be Done Reduce the amount of nutrients like nitrogen and phosphorous entering the Bay Reduce the amount of nutrients like nitrogen and phosphorous entering the Bay Reduce the amount of sediment entering the Bay Reduce the amount of sediment entering the Bay

8. Who Can Help EVERYONE, DOING EVERYTHING, EVERYWHERE! EVERYONE, DOING EVERYTHING, EVERYWHERE!

9. Water Quality Improvement Is NOT The Only Issue Must manage fisheries Must manage fisheries Protect and restore ALL habitats Protect and restore ALL habitats Effective management of land in the watershed Effective management of land in the watershed
