SOUTHERN Cross University led a volunteer group of more than 200 people in the largest community-driven project of its kind, addressing concerns around water quality along the Clarence River.<\/p>\n

Teams collected sediment samples from 100 key locations across the catchment with samples taken to the Lismore laboratories for analysis.<\/p>\n

The survey was a collaboration between Clarence River Guardians volunteer group and Southern Cross University, after the extension of mining exploration licences and community concern over water quality in the catchment.<\/p>\n

“We’re establishing a baseline for future management,” SCU project lead Professor Scott Johnston said.<\/p>\n

“Rivers are delicate ecosystems and once they become polluted, it’s often difficult and slow to reverse.<\/p>\n

“Working with citizen scientists is the only way we can collect such a large number of samples over a single weekend. This ensures a significant and robust dataset.”<\/p>\n

By analysing sediment for more than 50 different elements, researchers can detect the presence of heavy metals, metalloids and trace elements.<\/p>\n

It provides a reference point to assess any future changes, particularly those associated with mining activities and how they might influence water quality.<\/p>\n

 <\/p>\n

A unique aspect of the project is the co-design and walking together with First Nations custodians.<\/p>\n

All sediment samples will be returned to their points of collection in the river after the analysis is complete, out of respect for Country, the River and Traditional Owners.<\/p>\n

The citizen scientists sample water using a sophisticated digital probe, taking photos of the readings which are uploaded to a WhatsApp group that includes community members and University scientists.<\/p>\n

Professor Johnston enters and compiles the data, usually on the same day, and generates simple dot-colour scale maps and summary data, which is shared on-line via the Clarence River Guardians website, often within hours of collection.<\/p>\n

“This aids transparency and also provides strong incentive to the group as they can see the results of their efforts,” Professor Johnston said.<\/p>\n

“Citizen science backed by university training and analysis is a powerful tool for engaging the community and monitoring such pristine environments as the Clarence River catchment<\/p>\n
