The 20-acre Western Sand and Gravel site is a former gravel mining facility and industrial waste disposal area in North Smithfield and Burrillville, Rhode Island. Land use in the area is predominantly agricultural. The estimated 600 people who reside within one mile of the site use the underlying ground water as their drinking water supply. From 1953 to 1979, Western Sand and Gravel, Inc. (WSG) used the site for gravel mining operations. From 1975 to 1979, approximately 12 acres of the site were used for the disposal of liquid wastes, including chemicals and sewage waste. In 1979, the State conducted sampling of private domestic wells in the area and ordered the site to be closed because of violations of water and air pollution regulations and for failing to prepare complete and accurate industrial waste manifests. This final source control ROD addresses OU2, site closure and post closure provisions to contain contamination and minimize offsite migration of contaminants. Future RODs will address the contaminated ground water as OU3. The primarily contaminants of concern affecting the soil and sludge are VOCs including benzene, TCE, and PCE. The selected remedial action for this site is included.
