Detailed Site Investigation /
Phase III Environmental Site Assessment (ESA)

 

detailed site investigationA Detailed Site investigation (DSI) builds on the findings from a Preliminary Site Investigation (PSI), and is designed, often iteratively, to characterize the nature and extent of contamination identified through preliminary investigations.

A detailed site investigation provides the information needed to satisfy regulatory requirements. More importantly, they provide the information that enables comprehensive evaluation of remediation options and quantification of liability. Planning and executing the detailed site investigation requires anticipation of how the contamination may be remediated or managed. By providing a compilation and presentation of all field observations, field measurements, and laboratory analytical data, we are able to provide you with an interpretation and evaluation. In this way  we ensure we collect the data needed to assess and customize the remediation option and/or complete the detailed engineering design.
