We provide consultancy services to support the development of contaminated land policy and guidance on behalf of Government and regulators. We recently prepared

Best practice guidance for site characterisation: Managing contaminated land on nuclear-licensed and defence sites for CIRIA as part of the SAFEGROUNDS network - see

Contaminant Migration

We also undertake hydrogeological and geochemical modelling, in order to:

• estimate the rate of contaminant migration;
• predict the future extent and nature of the contaminant plume;
• provide the 'source terms' to underpin contaminant migration and risk assessment calculations;
• optimise clean up and liquid effluent treatment processes, and therefore
• optimise containment and remediation strategies.

 

Contaminated Land Characterisation

In the field of contaminated land characterisation, we undertake:

• initial desk studies leading to the identification of potential problems;
• design of groundwater and rock/soil sampling programmes;
• design of hydrogeological testing programmes;
• measurement of hydrogeological properties and groundwater chemistry,
• detailed site characterisation addressing potential contaminants, site geology and hydrogeology, and any possible gas or vapour generation issues; and
• site remediation validation surveys.

Risk Assessments

We use the information generated by these activities to support:

• environmental risk assessments of the contaminated sites;
• risk assessments of alternative remediation options;
• economic risk assessments;
• the assessment of site management options; and
• the development of strategies for managing portfolios of contaminated sites.
