Loureiro teamed with the PRP group consultants in support of remedial actions at an inactive CERCLA landfill in New Hampshire with volatile organic compounds (VOCs) and arsenic-impacted groundwater. The PRP group was concerned with the costs of a RCRA cap specified by the Record of Decision (ROD). An amended ROD was developed following pilot testing of alternative technologies and negotiations with the regulatory agencies. The primary components of the alternative remedy were a permeable soil cover to continue flushing of impacts associated with the landfill refuse (existing) and a source control system located along the downgradient boundary of the landfill. Design parameters for the source control system were based upon fate and transport modeling performed by Loureiro.
