Module 3 Water Quality Index

Stream Name: CHASTER CREEK | Survey Date: April 27th, 2024
Chemical Test Result Q-value Weighting Index Value
Temperature Change: Temperature 0 90.00 X 0.10 = 9
Oxygen Saturation: 106.50 98.00 x 0.17 = 16.66
pH (units): 6.82 85.00 x 0.11 = 9.35
Turbidity - JTU: 1.00 97.00 x 0.08 = 7.76
Total = Water Quality Index (Compare this value to the Water Quality Chart below)
