Hilo Bay Watershed: A Study of Water Quality in Hilo Bay and Wailoa and Wailuku Rivers
Students sampled and compared water quality parameters at three sites within the Hilo Bay Watershed: Wailoa River, Hilo Bay, and Wailuku River. They assessed water quality in Hilo Bay and looked at the role that both rivers play in contributing to pollution in the bay. Water quality parameters studied included temperature, turbidity, dissolved oxygen, pH, nitrate, phosphate, and salinity.
