Module 3 Water Quality Index

Stream Name: PEACH CREEK-Chilliwa | Survey Date: July 12th, 2016
Chemical Test Result Q-value Weighting Index Value
Temperature Change: Temperature 14.5 90.00 X 0.10 = 9
Oxygen Saturation: 120.00 90.00 x 0.17 = 15.3
pH (units): 6.49 68.00 x 0.11 = 7.48
Turbidity (cm): 60.00 80.00 x 0.08 = 6.4
Total = Water Quality Index (Compare this value to the Water Quality Chart below)
