Module 3 Water Quality Index

Stream Name: ALEXANDER CREEK | Survey Date: October 30th, 2013
Chemical Test Result Q-value Weighting Index Value
Temperature Change: Temperature Not enough data 88.00 X 0.10 = 8.8
Oxygen Saturation: 85.00 92.00 x 0.17 = 15.64
pH (units): 8.60 75.00 x 0.11 = 8.25
Turbidity - JTU: 0.00 98.00 x 0.08 = 7.84
Total = Water Quality Index (Compare this value to the Water Quality Chart below)
