- 5. 5 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.
- 6. 6 • 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 and water discharge tests are not part of the W.Q.I., but do give us a water quality rating.

- 31. Chemical Test Conclusions • Record low fecal coliform counts. • The last 4 years the Dissolved Oxygen numbers look considerably better. (possibly due to new equipment) • Nitrates have dropped compared to last year. • Site 2 and 4 WQI has gone up considerably, probably due to low fecal coliform counts. • Record high WQI for all sites! 31
