Phase III - Detailed Quantitative Risk Assessment

Detailed intrusive investigations are often required in order to establish ground properties and contamination characteristics (soil, groundwater and land gas) of the site. When dealing with land affected by contamination, investigations are carried out based on the technical framework for applying a risk management process as detailed in CLR 11 (Model Procedures for the Management of Land Contamination). A preliminary conceptual model and risk assessment is prepared as part of the desk study and allows for design of the site investigation.

Below are some of the software models and methods we use in-house to determine risk levels.

• Generic and detailed Quantitative Risk Assessments
• Soil Guideline Values
• Generic In-house Screening Values
• CLEA Analysis (Bespoke software)
• Sniffer Analysis (Bespoke software)
• RBCA
• Groundwater Risk Assessment – Consim and Environment Agency P20
• Land Gas Risk Assessment – based on CIRIA and NHBC Guidance

Geosphere Environmental are able to use any of or a combination of the above models to obtain the right criteria and target values for your sites.

• professional expertise

You will usually receive the quotation for the work on the same day.

A Consultant will be assigned to your project and then assess if any additional information is required to undertake the risk assessment for you. The Consultant will then undertake the risk assessment; the total time for the work will be five to seven working days from instruction to receipt of your risk assessment.

Liaison with Regulatory bodies if required will be carried out free of charge. The time scales relating to the agreement with the Regulators is beyond our control.
