GIAT Responsibilities
• Groundwater investigations of potentially impaired bores
• Implement and report on an independent monitoring
program
• Audit water monitoring bore
construction, well completion
reports for water monitoring bores
and water sampling procedures
• Engagement with industry and
community stakeholders on CSG
development and impacts
Implement and Report on DNRM’s Independent
Bore Monitoring Program
Learnings from Bore Investigations to date
• No bore problems to date have been as a result of CSG
• Landholders have little understanding of their bores and in particular
historical and current groundwater levels
• Biggest asset on their properties is the least understood
• Little landholder knowledge of CSG exploration / development /
likely impacts
• Often only source of information is over the fence discussions or
media articles
Old War Story
Volumetric Conversion Project – SE South Australia
• Conversion of existing area
based water licenses to
volumetric entitlements
• Provided incentives for
landholders to install meters
and collect water use data.
• Annual water use returns
where landholders calculated
volumes pumped.
Comparison Between Calculated and Metered Data
Benefits in Involving the Community
CSGNet
• Proactive program
• Landholders collecting data from their bores
• Provide current information on CSG
development and monitoring
• Inform landholders on local hydrogeology
and bore information
• Collect, store and report back
• Provide annual forum for sharing information
Transparency
Involvement

WHAT DO WE WANT TO MEASURE & RECORD
Artesian bore
• The Static Head
• If possible the bore should be shut off for at least
12 hours and a reading taken and recorded.
Sub-artesian bore
• The Standing Water Level
• If possible the pump should be shut off for at least
12 hours and a reading taken and recorded.
HOW CAN WE DO THIS ?
• Accurately
• Easily
• Economically
Airline & Pressure
gauge setup.
Involving Pump Suppliers / Installers
• Pump companies important conduit to landholders
• Local suppliers invited to CSG Net workshops
• Airline kit giveaways as ‘incentives’
• Encourage landholders to install airlines whenever
undertaking pump maintenance activities
• Will be holding regular workshops with suppliers to
provide support and share information & methods
Benefits
• Landholders empowered to monitor their own bores
and ‘own’ data
• Improved understanding of CSG industry,
groundwater systems and their bores
• Early warning of any CSG impacts on bores
• Change the bore monitoring paradigm to a ‘must do’
• Flow-on benefits to the Pump Supply and
Maintenance industry.
