Summary
The U.S. Army Corps of Engineers (USACE) New England District is issuing this Solicitation Announcement to perform the work described below for a single award of a Firm-Fixed Price (FFP) service contract set-aside for small business. The NAICS Code for this procurement will be 562910 (1000 Employees). The Walton and Lonsbury Superfund Site is a former electroplating facility that operated from 1940 to 2007. Since 2010, several environmental investigation and remediation activities have been performed at the site, including removal of Walton and Lonsbury facility buildings and residual waste materials, excavation and disposal of contaminated site media, and installation of an engineered cover behind residences along Paulette Lane and North Avenue to prevent upwelling of chromium-contaminated groundwater to the ground surface and to prevent direct exposure to chromium-contaminated soil. A PRB was constructed on the downgradient edge of the cover, with the goal of using zerovalent iron (ZVI) to reduce hexavalent chromium (Cr[VI]) to the less toxic trivalent chromium in groundwater before it discharges into Bliss Brook southeast of the Walton and Lonsbury property.
