On Monday 5th September, our students participated in a field sampling exercise at Lake Pertobe, Warrnambool. They worked alongside the Deakin University 2nd year marine studies students. They took sets of water quality measurements all around Lake Pertobe using some very expensive equipment. It was amazing to see how the water quality measurements varied depending on the location due to the different sources of water entering Lake Pertobe.

On Tuesday 18th October, our students attended Deakin University, Warrnambool and analysed samples of water taken from Tea-Tree Lake, Mortlake. This took place at the Deakin University’s commercial water quality laboratory.

Students also gained an appreciation of who may bring in water samples and what they are tested for. In the afternoon, there was a talk by one of Deakin University’s researchers. He showed the various types of chromatography equipment and how they were being used. This is much better than relying on the textbook and videos from Youtube.
I want to thank all the Deakin University staff involved for giving up their valuable time for making these two activities such a valuable learning experience for our students. I would also like to thank our lab technician, Doris Williamson for assisting with the driving and supervision duties on these days.
