Export of Acidity in Drainage Water from Acid Sulphate Soils

摘要

Disturbed acid sulphate soils are potent sources of acidity in coastal waterways. Monitoring studies of the drainage water for sites at East Trinity, Cairns and Pimpama, south-east Queensland indicate that considerable acidity is found in the drainage water from these sites. Hydrogen (H~+), ferrous (Fe~2+) and aluminum (Al) ions are the dominant acid cations involved.
