HGL is proud to support the U.S. Environmental Protection Agency (EPA) in designing all components of the final remedy for the Walton & Lonsbury Site in Massachusetts. The EPA recently designated more money for the environmental cleanup of the Superfund site in Massachusetts. The money is being provided through the 2021 Bipartisan Infrastructure Law, which includes funding for cleanup projects at 22 Superfund sites throughout the nation.
The primary contaminant at the site is hexavalent chromium. HGL’s remedial designs include plans and specifications for removing contaminated soil and the remaining Walton & Lonsbury facility features (e.g., concrete floor slab) and disposing of them off site; in-situ soil mixing at the former Walton & Lonsbury facility property; constructing a 350-foot extension to the existing permeable reactive barrier along Bliss Brook; and completing in situ injections of a reducing amendment along the west side of North Avenue in the “mid-plume” area.
