AAI designs and implements work plans, feasibility studies and remediation systems at sites that have significant soil and/or groundwater contamination problems that require cleanup. The most common type of cleanup is soil excavation and removal to an appropriate disposal facility (dig and haul). The second most common technique is a soil vapor extraction system (SVE), which includes the installation of soil vapor wells and utilizing a motorized vacuum. This system works well at volatile-contaminated sites with shallow sandy soil contamination.
If a contamination plume can be shown to not be a human-health risk and the source has been removed, monitored natural attenuation and passive biodegradation can be effective. This is often done in concurrence with a deed restriction at industrial properties. The land-use limitation, deed restriction or conveyance will state that any redevelopment or change in use will require cleanup in the future.
The following list of remediation techniques are available at sites where the budget and parameters are optimal for the various techniques.
