Geography Excursion

Our Year 12 ATAR Geography students spent time assessing the effectiveness of the Living Stream Program in Bodkin Park recently.
The hands-on excursion gave students the opportunity to evaluate whether the addition of the stream impacted the water quality of Canning River.
Teacher Sara Tyrell said the students took part in a variety of activities to observe how the river’s land use had altered since colonisation, and the impacts of these changes.
“Students were able to add a pollutant to a catchment model to see the impacts on the river,” she said.
“They then measured turbidity, phosphate, nitrogen and dissolved oxygen levels in the urban drain to compare the results with the living stream.
“It was found to remove all the phosphate and reduce the sediment level to an acceptable level.”
