Identification & Remediation of Contaminated Land

Bettridge Turner & Partners is a multi-disciplinary Civil and Structural Engineering and Transportation Planning Consultancy which was established in 1988. The company possesses a wide range of expertise including geotechnical and geoenvironmental engineering, which encompass the increasingly important area of regeneration of brownfield sites.

The scope of services offered by the geoenvironmental engineering team includes the identification, investigation and classification of contaminated land, followed by the design, procurement and management of remediation schemes and gas monitoring programmes. These activities make a vital contribution in bringing such sites back to beneficial use, thus facilitating subsequent redevelopment.

The identification of potentially contaminated land can commence very early in the development process, with site pre-purchase reviews and the preparation, in collaboration with our other environmental colleagues, of due diligence reports for either site vendors or purchasers. This process identifies development risks and suggests mitigation measures that may be implemented, to reduce risk to the purchaser, which enables a realistic price to be agreed for a site.

Phase 1 and 2 investigations of sites are routinely performed for a wide range of clients in the private and public sectors. These investigations report on contamination issues from historical and current land uses, in the context of the latest CLEA guidelines, and involve the assessment of risks arising from exposure to contaminated land. Pragmatic solutions are recommended and incorporate the relevant requirements of PPG23, which enable development to proceed via the design and implementation of innovative remediation schemes.

While the interpretation of results and management of gas monitoring exercises have been a routine activity for over 5 years, BTP have recently added an in-house gas monitoring capability to their range of services. These activities include spike testing of potentially contaminated sites during phase 2 investigations and longer term monitoring of gassing landfill sites.
