Module 3 Water Quality Index

Stream Name: ROGERS CREEK | Survey Date: April 11th, 2017
Chemical Test Result Q-value Weighting Index Value
Temperature Change: Temperature 0 90.00 X 0.10 = 9
Oxygen Saturation: 130.00 85.00 x 0.17 = 14.45
pH (units): 6.90 85.00 x 0.11 = 9.35
Turbidity (cm): 38.00 71.00 x 0.08 = 5.68
Total = Water Quality Index (Compare this value to the Water Quality Chart below)
