Industrial point source hazard

A large number of industries discharge pollutants such as nutrients, heavy metals and other toxicants into streams. These contaminants can impact upon the health of streams, rivers and coastal waterways [1].

The number of industrial point sources per unit catchment area in Australia's Intensive Landuse Zone was used as an indicator of 'industrial point source hazard' in the assessment catchment condition, during the National Land and Water Resources Audit [2]. The point sources included quarries, mine sites, chemical plants, sewerage works, abattoirs and areas of intensive livestock production extracted from the Australian Rivers and Catchment Condition Database (formerly Wild Rivers [3,4]).

Coastal issues arising from industrial point sources

Some potential impacts on the coastal zone caused by industrial point sources are:

Existing information and data

More information and maps showing 'industrial point source hazard' can be found at the Catchment Condition Online Maps website [1]. Appendix I (pp. 311-312) in Volume 2 of the Australian Catchment, River and Estuary Assessment, 2002 contains a map of Australia's River Basins and Drainage Divisions in which each river basin has been assigned a number. These catchment numbers can be matched to a large number of coastal waterways in pages 316-363 of the same document. The catchment point source hazard scores for a large number of river basins are available in Appendix B (pg 65-76) of the Assessment of Catchment Condition in Australia's Intensive Land Use Zone: A biophysical assessment at the national scale [1].
