Sub Surface offer a complete Contaminated Land Risk Assessment (aka. Contaminated Land Surveys) service in support of planning applications and to satisfy the conditions of the Local Authority, NHBC or other warranty schemes.  Our Contaminated Land Risk Assessment reports are also suitable for due diligence purposes.

Our services include Phase I Desktop Studies and site reconnaissance to identify potential sources, pathways and receptors, and develop the initial Conceptual Site Model (CSM), Phase II Intrusive Ground Investigations to refine the CSM, and Phase III Options Appraisal and Remediation Strategy and Phase IV Verification Works and sign off.

Our team of qualified and experienced staff ensure our Contaminated Land Risk Assessments are carried out in accordance with current UK guidance including but not limited to Environment Agency CLR7 Model Procedures for the Management of Land Affected by Contamination, the British Standards Institute BS10175 Investigation of Potentially Contaminated Sites – Code of Practice, and the NHBC Guidance for the Safe Development of Housing on Land Affected by Contamination.

Our Geoenvironmental Engineers use various modelling, statistical analysis and geographical information system (GIS) software tools to quantify the risks.  The use of these tools often enables us to separate out clean zones and contamination hotspots thus reducing the amount of soil requiring remediation and minimise the cost to the client.

If a site is found to be affected by contamination, then we can provide advice on remediation options and are happy to liaise with Specialist Remediation Contractors to formulate the most cost-effective way forward.
