TRC brings an in-depth understanding of utilities' former manufactured gas plant processes, how these MGP wastes interact within the environment, the actual risks posed, and the best technical solutions for each site.

Industries

In addition to our involvement in historical investigations, site characterizations, building decommissioning, risk assessments, and feasibility studies at nearly 60 MGP sites with both upland and waterway impacts for utility and industrial clients, TRC has installed caps, hydraulic control systems, slurry walls, reactive walls, pipe sealing and liner systems, excavation with off-site treatment, and in situ stabilization. TRC also has patented a NAPL Traping cap that addresses ebullition that occurs in areas coincident with NAPL, resulting in potential contact with human and ecological receptors.
