Module 3 Water Quality Index

Stream Name: BYRNE CREEK | Survey Date: August 21st, 2013
Chemical Test Result Q-value Weighting Index Value
Temperature Change: Temperature 0 91.00 X 0.10 = 9.1
Oxygen Saturation: 90.00 99.00 x 0.17 = 16.83
pH (units): 7.50 91.00 x 0.11 = 10.01
Turbidity - JTU: 0.00 98.00 x 0.08 = 7.84
