AES has substantial experience with characterizing the extent and magnitude of petro-chemical releases to soils and groundwater. Our team of registered professionals and scientists develop and implement project work plans focused on cleaning up the site (as appropriate) and to obtain a release of liability or no further action determination for the incident from the various state agencies.

In general, AES approaches site characterization and remediation projects by first listening to our client's goals and then by developing a plan to meet those goals. Although each client and project has different goals and needs, One common theme we have heard from all our clients in this area of our service has been "Get it Done". AES has developed a general project approach that may be summarized in these following points,which insure that we only do that which is necessary to "Get it Done".

• Reasonable definition of environmental impact (site characterization)
• Identification of potential receptors of contaminants,
• Risk elimination for potential receptors,
• Remediation of impacted soils and groundwater if needed,
• Demonstration of attainment of a health- or risk-based site closure,
• Receipt of a release of site liability for YOU, our client.

The following graphic illustrates the progression of a sample project towards site closure:

The graphic below illustrates a typical environmental project as it progresses towards site closure under Pennsylvania Department of Environmental Protection (DEP) Act 2 land recycling and environmental standards program. Similar approaches are used by AES to obtain site closures in other states.
