Landowners and developers need to be fully aware of environmental factors and this is initially done through a risk assessment.
Preliminary Risk Assessments
A Preliminary Risk Assessment is a Phase I Desk Study which focuses on potential risks to human health, controlled waters and the wider environment. It can also be called a Phase I contamination survey, and is often a pre-requisite for planning applications.
Typical objectives include:
- Obtain information about the soil and groundwater conditions within the area of the site.
- Determine possible ground related contamination hazards within the site boundaries that may affect the proposed development.
- Provide preliminary development recommendations.
- Provide advice on further works required for the cost-effective reduction of risks to the development and procedures likely to satisfy regulators.
- Contamination risk assessment.
- Recommendations for Intrusive Ground Investigation (Phase II).
Completion of the desk study allows a preliminary conceptual model to be produced along with advice on the next stages. A preliminary geotechnical assessment can also be undertaken if required.
GRM uses industry guidance which includes:
- Land Contamination: Risk Management (LCRM, published 8th October 2020).
- BS 10175:2011+A2:2017, Investigation of Potentially Contaminated Sites.
