Neutralisation distance of acid drainage and migration range of pollutants

Abstract

Acid mine drainage (AMD) release to surface water is naturally followed by neutralisation and subsequent precipitation of the pollutants load. This occurs between 50 m to 50 km from source, depending on topography, hydrography, geology and chemistry. Factors influencing this distance are discussed in view of a cost-efficient mitigation of AMD pollution. This approach should complement the evaluation of AMD likeliness and potential neutralisation (acid base accounting). In the source-Transfer- Receptor framework, ABA provides information on source while neutralisation zone modelling provides information on transfer pathway. Remediation targets and facilities depend on the location of potential targets vs neutralisation distance.
