Module 3 Water Quality Index

Stream Name: BOWKER CREEK | Survey Date: November 4th, 2020
Chemical Test Result Q-value Weighting Index Value
Temperature Change: Site Not enough data 90.00 X 0.10 = 9
Oxygen Saturation: 78.00 75.00 x 0.17 = 12.75
pH (units): 7.50 90.00 x 0.11 = 9.9
Turbidity - JTU: 2.00 90.00 x 0.08 = 7.2
Total = Water Quality Index (Compare this value to the Water Quality Chart below)
