Why conduct a site assessment
Assessment of site contamination (site assessment) may be required either statutorily or voluntarily.
Site assessment is completed to gather accurate and complete site data to assess if any substance exists above background concentrations that present, or have the potential to present a risk of harm to human health, the environment or any environmental values under a given land use. Site assessment is required to be completed using methods that are compliant with current legislation, guidelines and industry standards. The site assessment process forms the basis of corrective actions that may be required to manage any identified risks.
How Enpoint approach site assessment
In Australia, the National Environmental Protection (Assessment of Site Contamination) Measure 1999 provides the national framework for site assessment, which recommends that the investigation of contaminated sites is carried out in stages. The staged approach is intended to progressively update the conceptual site model (CSM) while focussing and prioritising resources on the most critical risk drivers for the site.
Reporting of site assessment and management is completed under a staged approach as follows:
- Preliminary site investigation (PSI)
- Detailed site investigation (DSI)
- Remedial action plan (RAP)
- Site remediation and validation (SRV)
- Site management plan (SMP)
