Module 3 Water Quality Index

Stream Name: BOWKER CREEK | Survey Date: August 18th, 2020
Chemical Test Result Q-value Weighting Index Value
Temperature Change: Site Not enough data 90.00 X 0.10 = 9
Oxygen Saturation: 88.00 90.00 x 0.17 = 15.3
pH (units): 8.00 83.00 x 0.11 = 9.13
Turbidity - JTU: 2.00 90.00 x 0.08 = 7.2
Total = Water Quality Index (Compare this value to the Water Quality Chart below)
