This Inquiry has shown, meeting the Drinking-water Standards was only part of the story.
“Where the water source was an aquifer, the delivery of safe drinking water to consumers was dependent on the security of the source from contaminants. It was also dependent upon the water supplier being aware of and managing the risks of contamination of the water supply, and competent local authority administration of the broader resource management regime”.
The enquiry found that “it was highly likely that heavy rain inundated paddocks neighbouring Brookvale Road causing contaminated water to flow into a pond about 90 metres from Brookvale Road bore 1” and subsequently entered the bore. With the result that there was direct interaction and between surface water and groundwater, and hence increasing the source water vulnerability.
The enquiry also found that “the Regional Council’s knowledge and awareness of aquifer and catchment contamination risks near Brookvale Road fell below required standards. It failed to take specific and effective steps to assess the risks of contamination to the Te Mata aquifer near Brookvale Road and the attendant risks to drinking water-safety”.

On 22 March 2017, World Water Day, the Australian Water Association’s Victorian Branch, in collaboration with the Association’s Catchment Management Specialist Network, held a one day Catchment Management Technical Seminar in Melbourne. Karla attended the seminar, along with 70 delegates from Victoria and further afield.
The theme of the seminar was Catchment management for water quality, and the stated objective of the day was Building understanding between land managers, catchment management authorities and water corporations on how catchment management delivers water quality benefits.
The seminar was broken up into four sessions:
• Session 1: Policy frameworks for catchment management
• Session 2: The big picture and the state of the science
• Session 3: Managing and understanding pathogen risks in catchments
• Session 4: Practical responses to catchment issues
Whilst it was billed as a Victorian branch event, there were several interstate presenters and delegates which was really good to seek
The presentations were of a high quality and covered a range of contemporary catchment management issues. Initial feedback from delegates was very positive.
Karla is a committee member of the Catchment Management Specialist Network.
Brogo River Offtake
Karla recently visited Bega, NSW, to assess the source water vulnerability of the Brogo-Bermagui water supply system. The project considers the vulnerability of the water within the Brogo River, the microbial quality of the water and the capacity of drinking water treatment. Naturallogic, has completed similar assessments, for Clarence Valley Council, Hunter Water, North East Catchment Management Authority in recent months.
