What is Phase 3 Remediation?

Phase 3 remediation is undertaken if the Phase 1 and Phase 2 investigations have determined it is required. The Phase 3 assessment aims to develop a land remediation strategy to demonstrate how the site will be safely developed for its purpose.

The aim of any Phase 3 remediation works is to remove or break all the viable identified pollutant linkages on contaminated sites.  The end result being to make previously contaminated land ‘suitable for use’. Remediation could be required to contaminated soils, contaminated controlled waters (ground of surface water) and hazardous ground gases.

How Is Phase 3 Undertaken?

Phase 3 investigations aim to identify the physical extent of contamination. This will be based on recommendations made in Phase 2 investigation and may include intensive testing, monitoring, sampling and the design of feasibility studies for remediation and remedial plans.

What is Phase 4 Validation?

A Validation (sometimes referred to as ‘Verification’) report is vital to ensure that planning conditions associated with contaminated land are able to be satisfied and allow proposed developments to proceed.

The Validation Report details information relating to the work undertaken as part of the remediation. It will demonstrate the success of any Phase 3 remediation measures used to break pollutant linkages identified in Phase 1 & 2.


How Can EMS Geotech Help?

The nature of Phase 3 remediation is individuality, as such requires consultants who are experienced at finding innovative solutions to individual concerns.

In the first instance, EMS Geotech’s experienced Geo-Environmental Engineers will produce a detailed Remediation method Statement outlining the objectives, methodology and procedures required for the proposed on-site remediation works.

Based on this, we are able to organise, oversee and manage remediation onsite works throughout the entirety of the project effectively and to budget. We have positive relationships with the Environment Agency and Local Authorities which further assist us on delivery.

Upon completion of the remediation works, a validation report will be produced to demonstrate that the works have been carried out satisfactorily and remediation targets achieved. The validation report will typically include:

  • A summary of the works undertaken;
  • Copies of photographic and documentary records undertaken during the remediation works;
  • Laboratory chemical analysis certificates for all validation analysis undertaken; and
  • Details of further contamination identified during the site works (if applicable)

Examples of Project EMS Geotech Have Conducted:

  • Removal of asbestos impacted soils from a former farm site intended for a proposed residential development.
  • Numerous projects involving the removal of disused below ground fuel tanks from former fuel station forecourts for proposed residential developments.
  • Numerous projects employing engineered cover systems (combined impermeable membranes and clean soil) for proposed residential and commercial developments.
