Contamination Remediation Strategies and Method Statements

Name: Ruddlesden Geotechnical
Price range: $

If the contamination risk assessments show that remedial measures are required to protect human health and/ or controlled waters, a contamination remediation strategy/ contamination remediation method statement is produced.

Often required to satisfy a planning condition, this is a standalone document that clearly details all of the contamination remediation recommendations, together with the validation testing requirements, any long-term monitoring and actions to be taken if unexpected contamination is identified.

Remedial measures will commonly include source removal and/ or a barrier system (e.g. capping of gardens/ covering of hardstanding), but might include in-situ treatment or the use of an off-site soil remediation hub.

Case Study

Contamination Remediation Strategy Outlines Requirements for Residential Development

In order to satisfy a planning and NHBC land quality conditions, Ruddlesden produced a contamination remediation method statement, which summarised the contamination risks across the site and set out a clear and structured approach for remediating the site for the developer, to satisfy regulators and warranty providers. Ruddlesden geotechnical had previously undertaken a Phase 1 and Phase 2 contamination investigation and assessment, which had indicated that the site was covered by surficial thicknesses of made ground containing loose fibres of chrysotile asbestos. Additionally, several underground fuel storage tanks and a historical air raid shelter, filled with asbestos containing materials (ACMs). The remediation strategy included excavation and removal of the underground fuel storage tanks and ACM, to be undertaken by licensed contractors, together with capping of garden areas with 600mm of clean soil underlain by a geotextile membrane. The remediation strategy also outlined the validation testing requirements, which were subsequently undertaken by Ruddlesden geotechnical.
