Preliminary Assessment and Desktop Study
The first stage of assessment is known as a Phase 1 Environmental Site Assessment (ESA), sometimes referred to as a desktop assessment, and involves site investigation, interviews with past and present site users, historical database (including historical aerial photographs) analysis, review of historic land titles and planning documents, identification of data gaps, development of a Conceptual Site Model (CSM) and a general assessment of the potential for past and present site activities to result in contamination at the site.
This is a very important stage of the assessment process and if carried out effectively can address the requirements of the environmental site assessment driver without the need for further investigation and/or correctly identify potential site contaminants enabling future investigations to be properly designed and targeted to reduce future costs and liabilities.
