The use of monitored natural attenuation (MNA) as a remediation approach requires a sound understanding of natural attenuation mechanisms in order to evaluate their potential efficacy in achieving remedial goals. Many state and federal agencies recognize MNA as a viable remediation approach, but this alternative must be supported by adequate evidence of its effectiveness. Such evidence requires adequate site characterization to determine solute plume behaviour and includes an evaluation of natural attenuation processes, making realistic estimates of attenuation rates and source decay rates, and designing an adequate monitoring program to show that natural attenuation is occurring as expected.

This 2-day short course provides the conceptual and technical background necessary to evaluate natural attenuation mechanisms and their interaction with source and transport processes at sites with organic and inorganic chemicals. It also provides in-depth discussions of the mechanisms of natural attenuation, data collection and analysis, quantification of contaminant transport and fate processes, and regulatory considerations involved in implementing MNA as a remedy for groundwater contamination. The course stresses practical information and guidelines useful for evaluating natural attenuation and applying MNA as a remediation approach.

This course also includes an introduction and guidance on the use of CRC CARE Technical Report No. 15, “A technical guide for demonstrating monitored natural attenuation of petroleum hydrocarbons in groundwater”, to be given by the report co-author Barry Mann.

In producing this report CRC CARE relied on a project advisory group which included representatives of the Victoria, Queensland, Western Australian, New South Wales and South Australian environmental regulators and the petroleum industry in Australia. This has resulted in the report being utilised as the key technical guidance document on the implementation of MNA for dealing with Australian groundwaters impacted by petroleum hydrocarbons.
