Phase 3 Land Remediation

(Detailed Quantitative Risk Assessment)

A Phase 3 assessment is undertaken if required after the Phase 1 and Phase 2 investigations and develops a land contamination remediation strategy to demonstrate how the site will be safely developed in respect to the land’s end use.


Phase 3 investigations aim to delineate the physical extent of contamination based on recommendations made in Phase 2 assessments. This may involve intensive testing, sampling, monitoring and the design of feasibility studies for remediation and remedial plans. This study normally involves assessment of alternative clean-up methods, costs and logistics. The monitoring of water or gas over a period of weeks and a remediation strategy may be needed as part of this assessment which may form part of a validation report which signifies remediation has been completed.


The individuality and complex nature of a Phase 3 land remediation strategy requires a successful record of delivering projects effectively and to budget. Our positive relationships with the Environment Agency and many Local Authorities across the UK ensures this process is completed quickly and effectively.

The final phase is verification (Phase 4)

Following the remediation of the contaminated land, there is a possibility that the Local Authority and or the Environment Agency will require verification that remediation has been completed. ESI, now part of Stantec, will prepare a verification report to meet the request and will compile supporting documents outlining the utilised process.
