15 COUNTY ROAD

Hatheway and Patterson Company (HPC) is a former wood preserving facility located in a mixed residential and industrial area in Mansfield, Bristol County, Massachusetts. The HPC property comprises approximately 40 acres and is bordered to the north by County Street and residential properties, to the south and west by forested and wetland areas, and to the east by a welding and masonry supply company. The property is roughly divided in half by the Rumford River, which runs north to south, and by a railroad track right-of-way, which runs east and west. The Hatheway and Patterson Superfund Site was listed on the NPL because releases of dioxins, furans, and phenols from the facility to the Rumford River have impacted fisheries and wetlands, and releases of arsenic, chromium, copper, phenols (including pentachlorophenol (PCP)), and polycyclic aromatic hydrocarbons (PAHs) to ground water were deemed to pose a a potential threat to nearby municipal and private drinking water wells. Operations at the HPC property included preserving wood sheeting, planking, timber, piling, poles, and other wood products. HPC began wood treating operations at the property in 1953, although it operated at the facility since 1927. Operations between 1927 and 1953 are unknown. Prior to the HPC operations, the Site was utilized for various purposes including rail and truck shipment and storage of various materials, railroad maintenance operations, as well as bulk chemical transfer and processing facilities, although there may have been other uses as well. HPC historically used various methods and materials to treat wood on the property, including PCP in fuel oil, creosote, fluoro-chrome-arsenate-phenol (FCAP) salts, chromated copper-arsenate (CCA), Dricon(tm) (a fire retardant), and other chemicals.
