Waste Site Cleanup & Reuse in New England
Davison Property Site
At the request of the NH Department of Environmental Services, EPA and a contractor in the summer of 2010 came to investigate the Davison Property Site at 471 Second New Hampshire Turnpike in Hillsborough, NH. The town had condemned the house due to structural problems. Reddish sediments were seen in an intermittent stream that flows through the property and discharges to another stream flowing into the Contoocook River. About 130 people lived within a quarter of a mile of the site.
During the investigation, EPA found numerous piles of broken household and commercial electronics equipment; about 28 55-gallon containers; and more than 100 containers of 5 gallons or less, some of which are coated with residual of or partially filled with products such as paints, primers, cements, solvents, cleaners, gasoline, waste oil, or motor and hydraulic oil. Investigators detected arsenic, lead, antimony, zinc, mercury and polycyclic aromatic hydrocarbons. As a result, EPA recommended an immediate cleanup.
EPA and contractors began removal work on March 9 and for the next six days, contractors segregated materials and disposed of about 70 tons of construction and demolition debris. From March 10 to April 28, about 145 tons of debris were shipped off site. This included a cubic yard box of miscellaneous lab-packed waste; a drum of waste pesticide and flammable aerosols and a drum of waste corrosive, all shipped out for disposal. It also included about 44,000 pounds of cathode ray tube (CRT) monitors, electronic wastes and mercury-containing light bulbs sent for recycling In addition, two refrigerators, four air conditioners, eight propane tanks, one washing machine and one mercury thermometer were taken to Hillsborough Transfer Station for recycling.
Over the summer, the town demolished the building while EPA and contractors carried out restoration work. On Aug. 18, restoration activities were finished, including repairing the erosion control system and restoring a neighboring logging road area where the command post and equipment/supply staging area once was. Restoration also included putting down 54 tons of topsoil, grading, seeding and making sure erosion control measures were in place.
