PHYSICAL CHARACTERISTICS

v Landfill Area Coverage

Approximately 47 Hectares

v Waste Depth

About 15M

v Geology

The sub-surface geology is comprised of a lateritic cover with variable thickness averaging 4m. It is reddish brown in colour with sand and clay portions. This cover overlies an alternating sequence of sand and clay deposits. The top soil (0-50cm) and sub soil (50-100cm) are predominantly clay and slightly alkaline with a pH range
