Contaminated Land
Getting the most out of contaminated land
The sustainable reuse of brownfield sites is the perfect platform to establish future communities, modern-day commercial operations, and new critical infrastructure.
To realise the value of these contaminated land sites, it¡¯s important to understand the legacy issues of land and water contamination. Our goal? To devise strategies to mitigate risk, re-use waste materials on-site, and reduce carbon impacts.
By understanding the proposed development lifecycle for a brownfield site and characterising site conditions, we help determine the appropriate remedial solutions and inform the geotechnical earthworks design to prepare a site for development.
Our geo-environmental engineers and scientists will support you in both the design and interpretation of site investigation work¡ªas well as the subsequent creation of a remedial strategy and support through the delivery of the works. These strategies will be lean, seek to retain materials safely on-site, achieve regulatory approval, and make the development programme viable.
Whether you need initial appraisals, intrusive investigation, risk assessment, or remediation, we can help.
Ground investigations
Our initial desk-based studies review existing environmental data sources and ground conditions. We advise on potential environmental liabilities and site constraints to inform future development or investment. Phase 2 investigations provide the details to complete a risk-based assessment of a site. This includes the use of geophysics, drone surveys, trial pits, boreholes, and sensors to obtain data through the ground. Our work focuses on identifying potential contaminants of concern, receptors, and pathways linking the two.Quantitative risk assessments
UK environmental regulation is risk-based. Our team designs and carries out multiple levels of risk assessment for human health, ecological, controlled waters, and built environment receptors using the latest models for assessing soil, water, gas and vapour data. These risk assessments range from the relatively simple generic quantitative risk assessments to detailed quantitative risk assessments, always using multiple lines of evidence and sensitivity analysis to best inform interpretation and decision making.Remedial design
By assessing current remedial technologies, we deliver a remedial options appraisal that identifies the most sustainable solution to deal with the contaminants of concern. This is based on environmental impact, cost, social benefit, limiting off-site disposal, and programme. We secure approval from the regulators and collaborate with specialist remediation contractors to develop detailed implementation plans. These are aimed at integrating with other groundworks on site, and securing verification of the works on completion.Materials management plans
We develop materials management plans (MMP) and provide a qualified person (QP) declaration. These detail how existing materials will be reused safely and appropriately, avoiding off-site disposal, reducing construction vehicle movements and keeping materials on-site. MMPs significantly improve the sustainability and lessen the environmental impact of developments. We provide the required regulatory evidence to secure the necessary permits to undertake the excavation and reuse of materials.
