Module 3 Water Quality Index

Stream Name: LAWSON CREEK | Survey Date: July 17th, 2013
Chemical Test Result Q-value Weighting Index Value
Temperature Change: Temperature X 0.10 = 0
Oxygen Saturation: 100.00 x 0.17 = 17
pH (units): 90.00 x 0.11 = 9.9
Turbidity (cm): 50.00 40.00 x 0.08 = 3.2
Total = Water Quality Index (Compare this value to the Water Quality Chart below)
