Abstract
The research reported in this paper is focused on the cost-effectiveness of intervention
strategies to reduce pollution loads and improve water quality in South-east Queensland.
Strategies considered include point and non-point source interventions. Predicted
reductions in pollution levels were calculated for each action based on the expected
population growth. The costs of the interventions included the full investment and annual
running costs as well as planned public investment by the state agencies. The results
show that the cost-effectiveness of strategies is likely to vary according to whether
suspended sediments, nitrogen or phosphorus loads are being targeted.
