Following identification of above ground and sub-surface utilities, we undertake intrusive site investigations for chemical assessment purposes to identify the presence and significance of any soil and/or groundwater contamination and ground gas. We can undertake investigations on all types of site which may typically involve hand pitting, machine trial pitting, window sampling or other drilling method or combination of methods appropriate to the particular ground conditions. Geotechnical parameters can be incorporated into the investigation where necessary.
Upon completion of the investigation and chemical testing by appropriately accredited external chemical laboratory, the Conceptual Site Model is updated and a risk assessment undertaken on each of the identified pollution linkages. If the risk assessment process identifies unacceptable risks, an appraisal of remedial actions is required to help determine a strategy to mitigate the risks.
