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.

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

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.

Involve Landholders or Risk the Consequences
