  1. Agricultural Runoff Lena Shapiro and Nicole Melamed

  2. What is Agricultural Runoff? • Pollutants from farms are deposited into bodies of water • Nonpoint source Pollution (NPS): pollution from many different sources Causes: • Sedimentation • Irrigation • Pesticides/fertilizers • Livestock grazing

  3. Sedimentation • Soil is washed off of fields • Rain or wind transports sediment into water sources • Too much sediment clouds water • Clouded water  reducing the amount of sunlight animals get in the water • Sediment can clog fish gills and smother fish larvae • Prevents new life from growing in the pond

  4. Irrigation • Irrigating is done to supplement natural precipitation or protect crops against freezing and wilting • Excessive irrigation can cause erosion • All of this transports [bad] nutrients, pesticides, and heavy metals into bodies of water • OR it can decrease the amount of water that flows naturally in streams and rivers • Can cause selenium buildup which can kill waterfowl

  5. Pesticides/Fertilizers • Pesticides, fertilizers, and more are spread over the crops and soil • These chemicals can contaminate water) through runoff, when it rains • They poison fish, animals, food sources, and destroy animals’ habitats Pesticides Pesticides Pesticides Pesticides

  6. Livestock Grazing • Overgrazing increases erosion and exposes soil • Destroys fish habitats and stream banks because animals graze too close to other creatures • Also ruins floodplain vegetation necessary for water quality filtration • It contaminates your water

  7. Why should we care? • It costs the U.S. thousands of dollars to pay for damage and water waste • Algal blooms form everywhere and it’s • bad for tourism, due to the lack of watersports • terrible for the environment, killing multiple ecosystems and disrupting the food chain

  8. What YOU Can Do • Learn about the ways water drains into the ocean in your area and prevent your garden’s chemicals from getting into the drain • If it enters a storm sewer system, it’s left untreated, and goes into the water bodies we use for swimming, fishing and, in some cases, drinking water. • Don’t overwater your plants • Remove vegetation from areas where it can mold and affect water areas To stop over watering your plants

  9. What is being done? • Farmers are preventing this by measuring out how much water their plants need or create efficient irrigation systems with quality equipment • They’re using less harmful pesticides and fertilizers • Farm Bill 2002  funds for conservation programs

  10. Have any questions? • visit the National Service Center for Environmental Publications (NSCEP) ordering Webpage here: http://www.epa.gov/nscep/ordering.html • email U.S. Environmental Protection Agency Office of Water • the people from the Water Quality Program at (985) 447-0868 and theycan help you improve your water conditions
