Coramba Groundwater Monitoring

Coramba Groundwater Monitoring- Hydrocarbon Contamination

Groundwater contamination was discovered in Coramba 2002, when fuel odours were noticed by a resident near the Orara River. Subsequent investigations identified the source of hydrocarbon contamination to be from a nearby service station that had a leaking underground storage tank that has since been removed.

On discovering the contamination, actions were taken immediately by Council and the government agencies responsible, to safeguard the village’s reticulated water supply and introduce environmental monitoring.

On-going groundwater monitoring and the effects of natural processes indicate that the level of hydrocarbon contamination is continuing to decline and as a result, the Environmental Protection Authority has recently determined that the contamination is no longer significant enough to warrant the original restrictions.

Management of the site

The site is currently subject to an ongoing maintenance order issued by the NSW Environmental Protection Authority under section 28 of the Contaminated Land Management Act 1997.

Ongoing monitoring of the hydrocarbon contamination in accordance with the Groundwater Management Plan will continue to review contaminant trends to ensure levels continue to decline in line with the project’s aims. 

Further information in relation to Notices that relate to this site can be found on the NSW Environmental Protection Authority website.

Groundwater Monitoring Reports and Management Plan

The following reports outline the management plan for the site and the results of recent monitoring:
