Index of Groundwater Condition

The Index of Groundwater Condition (IGC) is an integrated assessment of groundwater conditions and aquifer characteristics. The IGC has been designed to:
 • Be an integrated measure of the environmental condition and human values supported by aquifers.
 • Provide a summary of the overall groundwater condition which is easily understood by a general audience.
 • Provide consistent datasets across Victoria.
 • Apply a consistent and robust methodology across all aquifers.

The IGC provides a summary of the extent of changes to each of the sub-indices:
 • Groundwater Quality.
 • Groundwater Quantity.
 • Environmental Values.
 • Environmental Risk.

The IGC is a tool to assist management of aquifers in Victoria and will be used to:
 • Benchmark the condition of aquifers.
 • Prioritise management responses.
 • Set management objectives and measure the effectiveness of long term programs for groundwater catchments.

The data for each of the sub-indices is collected through:
 • Groundwater Quality: Statewide DSE groundwater quality assessments.
 • Groundwater Quantity: DSE SOBN regular water level monitoring, Victorian Water Accounts, published reports.
 • Environmental Values: Statewide mapping of GDEs by the Department of Primary Industries 2009, Index of Stream Condition.
 • Environmental Risk: Published statewide maps.

What do you want to do?

1. Start a New Assessment

Begin by selecting from the list of aquifers. New information for an aquifer can be updated here. You can also get a list of bores. General bore information, including land use values, should be up to date before bores are included in an assessment. To begin the assessment, add a new reading at the bottom of the Aquifer Details page.

2. Review Completed Assessments

3. Download Raw Bore Information

Download groundwater level data here.

4. Download Groundwater Quality Results

5. Upload Bore Level Data

Bore level readings can be uploaded in bulk using the tool on this page.
You can also add and edit individual readings on the details page for each individual bore.
