Typically required in the case of open release sites, AEI assists our clients with assessing the extent of groundwater contamination. Through the installation and sampling of a network of monitoring wells, the lateral and vertical extent of groundwater contamination and the rate at which the contamination is migrating toward sensitive receptors such as surface water bodies and water supply wells is evaluated. We assist clients in achieving the necessary documentation to proceed toward site closure, or risk assessment and remediation if needed.
