Design of Assessment of Site Contamination Investigations

For assessment of site contamination (ASC) investigations, the National Environment Protection (Assessment of Site Contamination) Measure (ASC NEPM 2013) lists the design components as:

  • establishing the objectives of the investigation;
  • development of a conceptual site model (CSM) and identification of data gaps;
  • development of the data quality objectives (DQOs); and
  • design of a sampling strategy and optimisation of a sampling, analysis and quality plan (SAQP).

This technical note reviews the ASC investigation ‘design tools’, that is CSMs, DQOs and SAQPs, and provides notes and references to assist in their application in Queensland.

Easterly Point Environmental – Radiological dose criteria for heavy mineral sand residues (HMSRs) in Queensland

This article by Marc Salmon explores the application of radiological criteria for dose rates related to gamma radiation at sites or decision areas impacted by heavy mineral sands residues (HMSRs), which are being assessed under the Queensland contaminated land framework. These sites can include former heavy mineral sands processing plants and mining sites, or other land where HMSRs have been placed as stockpiles or fill, pumped as tailings slurries, or used for trenching backfill, sub-slab bedding sands, top-dressing, and the like.

The ASC NEPM (2013, B1) describes that specialised forms of assessment are required for sites affected by, amongst others, radioactive substances. In situations where these occur, the ASC NEPM recommends that guidance for assessment requirements is sought from the relevant jurisdictional environmental or health authority. And that while the general principles of site assessment are applicable, compliance with specialised safety protocols and assessment guidance is essential to ensure the protection of human health and the environment.

Overview of the Contaminated Land Process in NSW

The contaminated land management (CLM) process has been likened to being on a toll way, with various exits along the way. The objective is to get a site off the toll way at the earliest, appropriate exit; noting that it can be costlier and more time consuming to get back onto the toll way if one has exited prematurely.

Easterly Point has summarised the contaminated land management process in NSW, including the various stages of investigations and the different roles of a contaminated land consultant and accredited auditor.
