NG Shell Creek Data Powerpoint 2003

  1. 1. 2003 Shell CreekWatershed Study Researchers: Amanda Gasper,Melissa Gasper, Anjuli Mostek, Katie Stone, Katie Dunlap,Courtney Bennett, Brittany Pieke, Sarah O’Brien, Instructor: Mark Seier
  2. 2. Introduction•Site 1- Instead of testing on Paul Cederland’s property, we moved to a site on Tim Krueger’s farm. This enabled us to have a sight on the South branch• Site 2- This is the site with established buffer zones. It is on the North branch. Here we have roadside access to the site.• Site 3- Located on Brad Wallin’s land. At this point, the north and south branches have already converged.• Site 4- Just below Newman Grove on Katie Hallgren’sproperty. Scoured banks are trademark to this site. Italso lies below the waste water treatment facility.
  3. 3. WQI• The Water Quality Index was developed by theNational Sanitation Foundation as a standard systemto compare different bodies of water.• To determine the WQI, a series of nine testswere performed. These tests were: dissolved oxygen,fecal coliform, pH, Biochemical Oxygen Demand(BOD), temperature, total phosphate, nitrates,turbidity, and total solids. We also did a waterdischarge test which we use to measure the flow of thecreek in cubic feet per second.
  4. 4. • After the tests are completed, the WQI foreach section of the creek can be computed. Toformulate the WQI, we first computed Q-valueswhich is a number determined from a weightingcurve chart. We multiply this number by aweighting factor, which provides a measure ofthe relative importance of each test to overallwater quality. The water quality index rangesfrom zero to 100. Zero to 25 is very bad. 25 to50 is bad. 50 to 70 is medium. 70 to 90 is good,and 90 to 100 is excellent.
