Additional drilling will take place around the service station at Penneshaw in attempt to find the source of a mysterious and ongoing petrochemical leak. 

Previous “push-tube” sampling around the service station undertaken by the property owner had not located any leaks, and based on advice from the consultant, the council will implement a drill pattern to sample ground-water flows around the location.

The Kangaroo Island Council is awaiting advice from consultants on where to drill the test sites to find the source of petrochemicals leaking into Christmas Cove.

Councillors at the June council meeting heard from CEO Andrew Boardman that, at this stage, the service station was thought to be the only location with underground fuel tanks that could lead to the ongoing leak of fuel.

The leaking fuel has been tested and was determined to be "young" petrochemical in nature, that is it was new petrol and not aged oil or diesel from an old tank. 

The council was awaiting advice from consultants it had hired as to exactly where the drilling would take place, and the drilling would go down as deep as bedrock, he said.

“It will be focussed in and around the Cove area to establish a baseline of water sampling across the area and establish which quadrant the contamination may be flowing from.” Mr Boardman said.

Councillors also pushed staff to make public a progress report and any findings, as they had been fielding lots of requests for information from concerned residents.
