Abstract

Case studies of wetland filtration of mine waste water in constructed and naturally occurring systems in Northern Australia.

Abstract

The use of natural or artificial wetlands to treat mine waste water in tropical Northern Australia is reviewed. Pit dewatering together with the monsoonal climate provide suitable conditions for wetlands. Wetland species, particularly Typha, flourish in the presence of shallow flowing water from dewatering. Metal reduction in wetlands is documented. Case studies of constructed and naturally generated systems and natural swamplands are cited. Paper presented at the IAWQ 3rd International Specialist Conference on Wetland Systems in Water Pollution Control, held in Sydney, Australia, from 23-25 November 1992.
