Annotation
Geological mapping and test pit logging has established the surface and near-surface geology of a 32 hectare proposed landfill site near Prospect. Well-defined soil profiles have developed. The B horizon consists of 0.5-2.0 metres of unfractured, impermeable clay. This material overlies almost all of the proposed site and will probably prevent leachate pollution of the underlying confined groundwater. Further recommendations regarding drainage investigations and monitoring are made.
