Continued Tests of Water Quality in Audubon Park
On March 1, 2014 at 10:00am two Jr. Entomologists, Sara and Richard, and two AquaKids, Lily and Ashley, tested water quality in Audubon Park. We tested for dissolved oxygen (DO), pH, water and ambient temperatures, turbidity, and humidity. We also observed the biotic and abiotic factors of the area. The biotic factors were coots, mallards, whistling ducks, a white ibis, red eared sliders, yellow bellied turtles, squirrels, cypress trees, oak trees, Bradford pear trees, sago palms, and elephant ear plants. One of our observations was that there was no duckweed on the water as previously observed during the summer months.
It was a sunny day with a light breeze. The water and ambient temperature was 19 degrees Celsius. This is because of our testing site had a turbidity of 54 cm, which means that the sun can warm up the water easily. It should be noted that the water was very shallow. The DO was 4.8 ppm. The pH was 8.7, which is slightly acidic for fresh water.
As a group we noticed an abundant amount of trash in Audubon Park and we ended our day by picking up the litter near the lagoon.
