Today, January 11, 2014 at 9:30am, we (Audubon youth volunteers of the Aquarium and Insectarium) tested the water quality of one of the lagoons in Audubon Park. Together, we tested turbidity, DO (dissolved oxygen), pH, salinity, and water temperature.
The mean of the water temperature was 8.3˚C.
Turbidity is the clarity of the water. Our second result was an average of28.5 centimeters.
DO is the amount of oxygen dissolved in water. We had a final result of 9.8mg/L
pH is how acidic or basic water is. The average number for freshwater is between 6 and 7. Our result was 6.5.
Salinity is the amount of dissolved salt content of a body of water. 1.02 ppt was the result of our testing.
