Water Quality Index

Use the Venier Dissolved Oxygen probe to measure the concentration of D.O. in mg/L. Record your reading. Use the Oxygen saturation chart below to determine the % saturation. Find the Q-value using the chart provided. Record the D.O. Q-value on the WQI Worksheet. pH: Pure water contains equal amounts of Hydrogen (H+) and Hydroxide (OH-) ions. ................
