  16. 16. 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. 16
  17. 17. • 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 are not part of the W.Q.I., but do give us a water quality rating. 17

  40. 40. Chemical Test Conclusions• Phosphates were high in June.• Fecal Coliform was a problem at certain times.• Nitrates seem to have peaked in 2008 and have since dropped down.• Some of the results may be due to high rainfall.• The flow, nitrates levels, and rainfall are continuing to correlate. 40
