Project Experience: Bell Power Systems


Client: Bell Power Systems

Location: Middletown, Connecticut

Project: Chlorinated Solvent Contaminated Soil and Groundwater Remediation

Description:

  Investigation into the extent of soil and groundwater contamination was performed to determine the horizontal and vertical extent of chlorinated hydrocarbon contamination, as well as petroleum contamination from a faulty oil/water separator. The monitoring wells indicated low levels of contaminants in the area of the previously removed separator with migration extending 300 feet.

  A comparison of various remediation alternatives was performed and the design of a soil vapor extraction and air stripping pump and treat system were chosen, based on timeliness, costs, and regulatory agency influence.

  A vapor extraction trench system was installed. A 250 foot groundwater recovery trench was installed due to the tight soils and low yields with a groundwater pump and treat system installed with an iron removal system and low profile air stripper to treat up to 10 gpm. All water discharge permits were obtained in order to operate the system. Air discharge calculations were performed, and air permits were not required due to the level of emissions.
