Site Investigations - Geo-Environmental

The second phase of the iterative Contaminated Land Assessment process involves the conduct of an intrusive Site Investigation. The purpose of an intrusive Site Investigation is to investigate each potential source of contamination identified by the Desk Study. As such each site investigation conducted must be bespoke and designed to target the issues at each particular site in relation to the proposed development based on the Site Conceptual Model derived from the Desk Study. SEC employs numerous different in-situ exploratory methods to carry out the intrusive Site Investigation. The method of investigation used can depend on a number of factors derived by the Desk Study including the sensitivity of the site and the surrounding area, the anticipated ground conditions, the nature and size of the site and the nature and type of potential contaminants. •Hand Pits; •Hand Augering; •Machine Excavated Trial Pits; •Windowless Sampling / Continuous Dynamic Sampler Boreholes; •Cable Percussive Drilling; •Rotary Drilling; and, •Sonic Drilling During site investigation works SEC provide full time site supervision by Geo-Environmental Consultants who are trained in site investigation techniques, soil and rock logging, monitoring, sampling and recording data in accordance with current British Standards. Our consultants carry CSCS cards, are trained to use cable avoidance tools and are also fully trained in First Aid. Following the conduct of site works, samples are analysed at fully accredited laboratories and all testing is completed to either UKAS or MCERTS certification. Perhaps the most important aspect of the intrusive Site Investigation is the compilation and interpretative of all the data collected.
