    • 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. 3
    • • 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. Zero to 25 is very bad. 25 to 50 is bad. 50 to 70 is medium. 70 to 90 is good, and 90 to 100 is excellent.• The bio-indicator tests weren’t part of W.Q.I., but did give us a water quality rating. 4
