  1. 1. River Raisin & Stony CreekWater Quality ProjectSponsored by the Monroe County ISD Mr. Dornberg Mrs. Hunter
  2. 2. Why are we doing this?"We do not just drink water; we are water.Water constitutes 50 to 90 percent of theweight of all living organisms. It is one ofthe most abundant and importantsubstances on the Earth.” - GLOBE, Hydrology, The Big Picture
  3. 3. About 21% of the worlds supply of surface fresh water iscontained in the five Great Lakes
  4. 4. Freshwater lakes contain .007% of all the water in the worldThe world’s water <2 Tablespoons Source: Igor Shiklomanovs chapter "World fresh water resources" in Peter H. Gleick (editor), 1993, Water in Crisis: A Guide to the Worlds Fresh Water Resources (Oxford University Press, New York).
  5. 5. What is a Watershed?“A watershed is the area of land where all of the water that isunder it or drains off of it goes into the same place.” -US EPA
  6. 6. River Raisin Watershed Facts• Approximately 1,072 square miles, 150 miles long• Home to 140,000 people• 5 Michigan Counties: Lenawee, Monroe, Washtenaw, Jackson, Hillsdale; small portion of Fulton County Ohio• Over 400 lakes & ponds• 3,000 miles of man-made drainage systems Source: http://riverraisin.org/features/river_raisin_watershed_info/index_html
  7. 7. Stony Creek Watershed Facts• Relatively small area: – 32 miles long, 8 miles at widest point• Washtenaw and Monroe counties in Michigan• Upper watershed is highly developed• Lower watershed is primarily agricultural Source: http://www.michigan.gov/documents/deq/ess-nps-wmp-stony-creek_208933_7.pdf

  12. 12. REAL Science!• Water temperature• pH• Dissolved oxygen• Nitrates• Salinity
  13. 13. Dissolved Oxygen• Sources of DO – aquatic plants – aeration: waterfalls, waves, splashing• Range of values: 0 to 16 mg/L• Changes throughout the day and throughout the year
  14. 14. Dissolved Oxygen Levels• < 3.0 mg/L : most organisms die• < 5.0 mg/L : cause for concern• < 7.5 mg/L : sensitive organisms die
  15. 15. Nitrates• Needed for aquatic plant growth• Too much causes growth of algae and excessive plant growth• Levels affected by run-off• Generally range from 0 to 10 ppm
  16. 16. pH• Measures the acid content of water• Ranges from 0 – 14.0• 7.0 is considered “neutral”• Most lakes and streams: 6.5 to 8.5• Affected by geology and rainfall
  17. 17. Coke & Pepsi 2.5Most amphibians and insects can’t survive ifpH is <4 or >10
  18. 18. Salinity• Measures dissolved salts in water• Measured in “parts per million” or ppm• Oceans: average 35000 ppm• Fresh water: <500 ppm <1000 ppm
  19. 19. Salinity 500 to 1500 ppm• Can be consumed by humans although most would prefer water in the lower half of this range if available• Can be used for irrigation depending on plant/crop tolerance• Suitable for all livestock Source: http://www.dpi.vic.gov.au/dpi
  20. 20. Salinity 1500 to 6000 ppm• Not recommended for human consumption. Water up to 1800 ppm could be drunk if nothing else available• Not normally suitable for irrigation, though water up to 3600 ppm can be used on very salt tolerant crops• Water over 2400 ppm can cause shell cracking in laying hens• Drinking water for poultry and pigs should be limited to about 3600 ppm• Most other stock can use water up to 6000 ppm
  21. 21. Safety First• Life jackets• Gloves• Goggles• Long sleeves• No shorts• No sandals, open-toe shoes, or heels
  22. 22. Safety Precautions
  23. 23. Proper Analytical Techniques
