Human Health Contamination Risk Assessments

Human health contamination risk assessments are undertaken to demonstrate that the site is suitable for the proposed end use, often to satisfy a planning condition and/ or warranty provider (e.g. NHBC) land quality condition.

Following the preliminary risk assessment (Phase 1 Contamination Risk Assessment), these will typically take the form of a Generic Qualitative Risk Assessment (GQRA), where the results of the contamination laboratory testing are compared to Generic Assessment Criteria (GAC) to aid the evaluation of the extent of contamination at the site. If any of the GAC are exceeded, this may be indicative of an unacceptable risk to the health of site users and that further investigation, assessment and/ or remediation is required.

Case Study

Residential Redevelopment of Former Garage

A human health risk assessment at a proposed residential development site in North Devon was undertaken as part of a wider scope of works comprising a Phase 1 and Phase 2 contamination assessment, followed by the production of a remediation strategy and subsequent validation testing.

Case Study

Cliff Stability Assessment, Dorset

There was a stability risk at a cliff-top site on the Isle of Portland, as indicated by a Phase 1 Geotechnical Assessment, previously undertaken by Ruddlesden geotechnical.
