MacGillis & Gibbs Superfund Site
Sealand Enviro completed the remediation of the MacGillis & Gibbs Superfund Site as a prime contractor to the U.S. EPA. The work was overseen by the EPAâ€™s contractor Ecology and Environment. The site was an old pole wood treatment facility just north of Minneapolis. Sealand Enviro provided environmental engineering and construction services for the remediation of soils and groundwater throughout the site to Minnesota regulatory standards. Soil was transported to Subtitle C landfills using rail. An advanced groundwater extraction and treatment system was constructed and operated as part of the cleanup to remediate PCBs, heavy metals and dioxins.
