Site Investigation & Remediation

Site Investigation & Remediation

AEI Consultants provides full service environmental site investigation and remediation services to address a variety of pollutant conditions. Site Investigation includes comprehensive examinations, appropriate design and plan installations and feasibility studies to determine the contamination severity and mitigation methods on contaminated sites. AEI’s dedicated engineers develop effective solutions in order to successfully complete thousands of site investigation and remediation projects on schedule.

Our experienced project managers and professional geologists, engineers, and scientists identify cost-effective solutions and develop long-term relationships with our clients to understand their budgetary needs. AEI offers up-to-date knowledge of federal, state and local regulations throughout the United States. Quality control is strictly enforced and all work completed by AEI is documented and performed under the direction of a Professional Engineer or a Professional Geologist. AEI is well-known in the industry for our superior quality of work and client satisfaction.

Phase II Subsurface Investigations

A Phase II subsurface investigation would generally be recommended if historical documents or a site inspection suggests that soil or groundwater contamination might exist at the subject property following a Phase I Environmental Site Assessment (ESA).

The purpose of the Phase II Subsurface Investigation is to determine if contamination exist. Investigations determine the impact of the contamination on the soil and/or groundwater conditions beneath a property. Potentially contaminated sites that are recommended for Phase II subsurface investigations commonly involve:

• Dry cleaning operations
• Printing Facilities
• Manufacturing Facilities
• Gas stations
• Underground StorageTanks (USTs)
• Leaking tanks
• Hazardous materials surrounding the subject property

All of AEI’s Phase II Subsurface Investigations are performed by experienced professional geologists who establish the scope of work, determine the location of each sample and interpret sample results. All samples are analyzed by certified laboratories under the guidelines established by the American Society of Testing and Materials (ASTM).
Once the laboratory results have been acquired, a report is prepared which includes the subject property map, analytical laboratory sample results, and conclusions and recommendations for additional work, if required.

Soil, Soil-Vapor, Indoor Air and Groundwater Investigations

Soil, Groundwater and Soil-Vapor Investigations are performed to evaluate the extent of the identified contamination to soil and/or groundwater beneath a property. Site specific data is integral in evaluating the need for mitigation, human and environmental risks and obtaining regulatory closure.
Extensive soil and water sampling and laboratory analyses may be necessary to determine the extent of the contamination. In many cases installation of monitoring wells are needed for long term groundwater sampling monitoring. AEI’s comprehensive testing and evaluation procedure gives our clients the necessary information to make thoughtful, prudent business decisions regarding site cleanup.

Vapor Intrusion Studies

Vapor intrusion and vapor encroachment is encountered primarily at sites contaminated with volatile organic chemicals such as petroleum from leaking underground storage tanks or pipelines and chlorinated solvents from dry-cleaning facilities. Vapor Intrusion studies may involve sampling indoor and ambient air, soil gases, and groundwater. State and federal environmental initiatives have recently addressed vapor intrusion issues and will have significant impacts on future real
