Detailed Site Investigation (DSI)
A DSI generally involves intrusive investigation(s), to characterise the site and the nature and extent of any contamination. The data obtained are then used to update the CSM and assess risk to human and ecological health. A DSI can provide recommendations for further risk assessment or remedial works necessary to meet site management objectives.
Remediation Action Plans (RAP)
RAPs detail the type and extent of remediation required to ensure that the site is suitable for ongoing or future use, while considering risk to the sites surrounds. A RAP specifies remediation methods, clean-up objectives and criteria for assessing the effectiveness of the programme.
Site Remediation and Validation (SRV)
SRV is the implementation of the chosen clean-up approach as specified in a RAP. The validation being the process of evaluating the effectiveness of the remediation works in meeting the clean-up objectives.
