Walls will soon be going up to cut off the contamination from the Coke Ovens site in the Sydney Tar Ponds.


Construction will begin in July to stop clean ground water from reaching the contaminated area. The walls will be built along the north and south sides of the 68-hectare area.


“If continuous monitoring shows that more walls are needed to prevent clean groundwater from mixing with contaminated groundwater on the Coke Ovens site, we will construct more walls,” said Frank Potter, president of the Sydney Tar Ponds Agency, in a statement yesterday.


The walls are just one part of a $400 million agreement to clean up the tar ponds and coke ovens by 2014.
