Where a Phase 1 risk assessment has identified potential environmental risks that cannot be mitigated through an environmental management plan then a Phase 2 intrusive site investigation and quantitative risk assessment (generally referred to as a Site Investigation Report) is required.
In accordance with LCRM & BS10175:2011 the intrusive soil investigation includes taking soil and water samples from bore holes and trail pits at locations determined by the findings of the Phase 1 report targeting the area(s) identified as being potentially contaminated. It’s worth noting that your geotechnical survey can be undertaken at the same time to save money.

A friendly guide to site investigations
Have you been asked by your local planners or funders to undertake a site environmental survey, including intrusive investigation where necessary, to establish any environmental risks that may exist on your site? This guide will help.

The samples taken are then sent to an analytical laboratory to ascertain the presence of organic and inorganic chemical properties, with the resulting data sets being evaluated, using a ‘Source-Pathway-Receptor’ model on a quantitative basis, against suitable assessment criteria to determine the risks associated from contaminants identified at the site. Ground gas monitoring may also be required and this can extend the reporting process.
The initial conceptual site model will then be revised to include the recent findings. Where the identified contamination risks cannot be mitigated through an environmental management plan then an appraisal of remedial options with a resulting remediation strategy will be required.
