DRESDNER ROBIN was retained by Celanese North America to conduct remedial investigations of soil and groundwater at a property that had been designated by the City of Newark as the location for a new world-class aquatic center. Located in an industrial area in the Ironbound, the property had historically been used for chemical manufacturing for more than 50 years. Remedial investigations identified extensive soil and groundwater contamination as well as large volumes of Dense Non Aqueous Phase Liquids (DNAPL) or “free product”.
Following completion of the remedial investigations, Dresdner Robin was responsible for developing a remedial approach that would enable removal of an estimated 75,000 gallons of “free product” following completion of the proposed aquatic center. The designed remedial system consisted of a network of eighteen (18) remediation wells located both inside and outside of the aquatic center, all of which were connected through a subsurface utility conduit. The remedial system also included a complex synthetic engineering control to prevent vapors from entering the aquatic center. Specifications associated with the subsurface remedial components were prepared by Dresdner Robin and were integrated into the bid specifications for the construction of the aquatic center.
Dresdner Robin also designed the above ground components of the remedial system. Utilizing pneumatic pumps, free product underlying the building is accessed via the remediation wells and is transported through the subsurface conduit to a recovery system building where it is separated and containerized for off-site disposal.
