The Baird & McGuire site encompasses approximately twenty acres in Holbrook, Norfolk County, MA. Wetlands occupy approximately 44 percent of the site with approximately 66 percent of the site lying within a 100-year flood plain. Baird & McGuire, Inc. (BMI) operated a chemical mixing and batching company from 1912 to 1983. BMI's disposal practices were the source of ground water and wetlands contamination. In 1983 heavy rains caused a breach of the creosote collection lagoon resulting in an EPA-initiated Immediate Removal Action. Dioxin, detected in surficial soil samples in 1985, prompted an EPA-initiated second removal response involving the installation of 5700 feet of fencing and extensive soil, ground water, surface water, and air sampling. The primary contaminants of concern include: VOCs, organics, PAHs, dioxin, pesticides, and metals. The remedial action includes excavation in 'hot areas' to remove approximately 191,000 cubic yards of contaminated soils, onsite incineration of excavated soils, ground water extraction and onsite treatment with discharge to an onsite aquifer; restoration of wetlands, construction of levees and ground water monitoring. The estimated capital costs are $44,386,000 with 30-year O&M costs of $4,132,000.
