- HARTLAND LANDFILL -
Leachate from the Hartland Landfill in Victoria is discharged to Victoria’s sewage collection system and released into the marine environment via the Macaulay Point outfall. The Hartland Landfill is a significant source of toxins. Concentrations of 8 of 21 chemicals in the Macaulay Point Outfall are raised considerably (see table below) due to the Hartland leachate. It is assumed that 3% of the outflow at Macaulay Point is leachate from the Hartland landfill.[1]

WAD = weak acid dissociable
Hartland leachate = mean concentration of Hartland leachate from 1997-2004
Macaulay Point outfall = mean concentration of Macaulay Point outfall from 2000-2004
Macaulay Point effluent = calculated assuming 3% of the outfall is leachate from the Hartland landfill
