Mid-plume groundwater remediation at the Walton and Lonsbury Superfund Site, Attleboro, Massachusetts

The U.S. Army Corps of Engineers New England District is seeking a single award firm-fixed price contract, set aside entirely for small businesses, under NAICS code 562910 (Environmental Remediation Services). The contract involves mid-plume groundwater remediation at the Walton and Lonsbury Superfund Site in Attleboro, Massachusetts, a location with a history of environmental contamination due to its past as an electroplating facility operating from 1940 to 2007. Previous remediation efforts have included demolition of buildings, removal of contaminated materials, and installation of protective covers to prevent human exposure and control chromium contamination in the soil and groundwater. This solicitation, posted on December 12, 2025, requires performing further groundwater remediation work that involves the use of a permeable reactive barrier (PRB) containing zero-valent iron to reduce the toxic hexavalent chromium to the less harmful trivalent form before it reaches nearby Bliss Brook. The contract deadline for submissions is February 12, 2026. The project is managed by the Department of Defense’s New England District office in Concord, Massachusetts, with Kyle Hall as the primary point of contact. The effort supports ongoing environmental cleanup efforts aimed at protecting public health and the environment in the affected area.
