  10. 10. W.Q.I.• The Water Quality Index was developed by the National Sanitation Foundation as a standard system to compare different bodies of water.• To determine the WQI, a series of nine tests were performed. These tests were: dissolved oxygen, fecal coliform, pH, Biological Oxygen Demand (BOD), temperature, total phosphate, nitrates, turbidity, and total solids. We also did a water discharge test which we use to measure the flow of the creek in cubic feet per second. 10
  11. 11. • After the tests are completed, the WQI for each section of the creek can be computed.• To formulate the WQI, we first computed Q- values.• We multiply this number by a weighting factor, which provides a measure of the relative importance of each test to overall water quality.• The water quality index ranges from zero to 100. - 0 - 25 is very bad - 25 - 50 is bad - 50 - 70 is medium - 70 - 90 is good - 90 - 100 is excellent• The bio-indicator tests weren’t part of W.Q.I., but did give us a water quality rating. 11
