Phase 3

Remediation Strategy & Remedial Works

Why is a Phase 3 Remediation Strategy needed? 

Where the Phase 2 Site Investigation has described the unacceptable risks to receptors, a Remediation Strategy outlines how to reduce these risks, and a Phase 4 Validation Report shows how these measures have been implemented and proven. 

What is involved in a Phase 3 Remediation Strategy?

In order to implement this phase of the assessment, an LCRM Stage 2 Remediation Options Appraisal is carried out, and presented in an LCRM Stage 3 remediation strategy. For consistency, CGA and numerous other consultancies refer to our remediation strategy report as Phase 3 of the land contamination assessment process. The aim of the Options Appraisal is to ensure the most cost effective, appropriate and achievable Remediation Strategy is chosen.

At this stage, additional site investigation works may also be recommended for further laboratory analysis, or where a pilot remediation scheme or long term monitoring of the remediation works is required.

    The Remediation Strategy is designed to:

    • Provide site remediation criteria for the relevant contaminants that are achievable or as low as reasonably possible;
    • Ensure that all the appropriate environmental permits and licences will be applied for;
    • Demonstrate that none of the remediation activities will create new pollution pathways;
    • Identify potential mitigation measures should significant variations to the remediation strategy occur;
    • Detail the validation methods, including the number of laboratory tests required;
    • Outline supervision requirements.

    Most commonly, the most appropriate and cost-effective remediation method entails removal of contaminated soils and replacement with verified clean imported soils. In some cases, the imported soils will serve as a cover blanket between eventual site users and deeper contamination.

    It is fairly common for developers to choose to instruct the same consultant for the Remediation Strategy as the Site Investigation.
