FORMER MANUAFACTURED GAS PLANT (MGP) SITE REMEDIAL ACTION
Industry: Utilities
Location: Midwest
In-situ solidification and stabilization transforms former MGP site
ENTACT undertook the remediation of a former MGP site situated in an urban area, adjacent to light industrial and commercial developments, as well as undeveloped land and a shallow river. Historical releases of MGP residuals had contaminated soil and groundwater, leading to the migration of pollutants to the riverbank, affecting an isolated sediment area. During the project, ENTACT:
- Developed a treatability study
- Demolished concrete footings and slabs
- Excavated and disposed of 10,500 tons of impacted soil off-site
- Installed180 linear feet reinforced concrete pipe, including a manhole and headwall
- Performed in-situ solidification and stabilization of 30,000 cubic yards of impacted materials
- Restored the site to natural grade with topsoil, native grasses, and trees
- Stabilized the riverbank through riprap placement
