Water quality profile of an urbanising catchment

Abstract

Contamination of waterways a critical issue, especially in areas undergoing rapid urban development. The Ningi Creek catchment in Caboolture Shire, Queensland State, Australia is a prime example of such an area. A recent study had revealed a serious faecal pollution problem. The catchment area of Ningi Creek contains a number of landuses, including forestry, farming, aquaculture, rural-residential and residential developments serviced by onsite wastewater treatment systems. Any of these can cause contamination of the ground and surface water, particularly during rainfall events.
