Remediation Method Statements

The Phase 2 report is likely to contain a number of remedial options but the process of providing a Remediation Method Statement involves the necessary authorities and this document details out the necessary steps that are required in order to return a parcel of land to be suitable for its end use. The works carried out in line with this will normally require a verification process.
The Land Contamination Risk Management (EA, 2020) guidance Stage 2 and 3 processes also include a remediation options appraisal and any required process to be detailed in a Remediation Method Statement.
Remediation of a site may be a simple single stage or a more complex multi-stage process which can also include several reporting stages:
- Liaison with Local Planning Authority Environmental Health Officer
- Scrutiny of data for imported materials (e.g. topsoils, subsoils)
- A watching brief for material to be removed
- Various site visits to test stockpiled materials that have been or are to be imported or site-won materials that are intended for re-use
- Assessment of the proposed layouts and modification of these in order to mitigate risks posed by the site/to receptors
- Installation of various mitigating measures (e.g. incorporation of hydrocarbon or other gas resistant membranes, capping, etc.)
The works carried out in line with this will normally require a verification process.
What is the output?
The output is a conceptual model review in a report that essentially shows the levels of risk and how they are reduced by implementation of the remediation techniques involved.
How are the reports presented?
Our reports are provided in PDF format via email.
Contaminated Land Investigation
Kiwa CMT | We examine ground contamination

Gas Monitoring & Assessment
Kiwa can provide a standalone Ground Gas Monitoring service, or as part of a more detailed Phase 2 Intrusive investigation where assessment is made to BS8485 (Code of practice for the design of protective measures for methane and carbon dioxide ground gases for new buildings).

Phase 1 Desk Study
In line with the Land Contamination Risk Management Strategy (Environment Agency, 2020), BS5930 and Eurocode 7 (EN 1997) all ground investigations should be preceded with a suitable Phase 1 Desk Study and Site Walkover to provide a baseline information package about any site.

Phase 2 Intrusive Investigation
The Land Contamination Risk Management (EA, 2020) guidance Stage 1 process requires further information and refinement on the risk assessment process for the Source – Pathway – Receptor contamination linkage.

Verification of Remediation
Verification of Remediation Site Works and Reporting (Stage 3 LCRM – verification and future works)

Site Investigation
Kiwa CMT | We provide a range of ground investigation services

BS3882 Topsoil Testing
The BS3882 topsoil suite is specifically designed to categorise grades of topsoil based on physical and chemical composition.
