Temporal trends in water quality

Water quality monitoring probe in the Georges River

During 2021, as part of our Research Program, Georges Riverkeeper partnered with students at Macquarie University on projects with 'real world' implications.

One of the student groups investigated Georges Riverkeeper’s extensive water quality dataset, something that has not been done since 2016. Due to time constraints, a few sites and parameters were selected.

Across the sites analysed, students found fluctuation in the values across most parameters, but not necessarily any notable increase or decrease over the period since 2009.

Students also performed a literature review of others methods employed for trend analysis and found that a Mann-Kendall test is useful for integrating non linear trends. One site, in particular, heavily rejected the null hypothesis and indicated that a trend did exist.
