Environmental Assessment

Validation and monitoring

RSA Geotechnics have advised in a number of successful land remediation and validation schemes. Our involvement in a management or supervisory role is tailored to meet the needs of the individual project, whilst ensuring that sufficient information is collected and documented to allow approval and ‘sign-off’ from the regulators in due course.

Validation monitoring works can comprise inspection of the removal of tanks or ‘hotspots’ of contamination, sampling and testing of soils to confirm chemical suitability for a proposed end use, inspection of the thickness of a placed clean cover system to ensure it meets the agreed requirements, or groundwater sampling and testing to confirm remedial target values are being achieved following remedial works.

Our role in the project may be in the form of a ‘watching brief’ or in a more direct supervisory capacity working together with the development team, remediation specialists and the various construction contractors. Our team of geoenvironmental engineers carry out site monitoring and validation of the remediation operations, and inspections of associated documentation such as waste transfer notes and compliance certificates to ensure that the development meets the requirements of the agreed remedial strategy for the site.

The final stage of the process is the submission of a detailed verification report for the remedial works which will include copies of all records, drawings, plans and confirmatory analysis. The verification report is then submitted to the regulatory bodies to enable the remediation to be ‘signed off’ and any associated planning conditions to be discharged.
