The Mobil site, approximately 150 feet by 60 feet in area is located at 112-01 Beach Channel Drive in Queens, New York. The Volunteer, Mobil Oil Corporation, leases the Site and had previously operated a gasoline service station. During reconstruction activities at the Mobil Site in May 1995, several construction workers were overcome with fumes and were hospitalized. Subsequently, air monitoring and soil sampling were conducted by Mobil, NYS Department of Environmental Conserervation, NYS Department of Health, NYC Department of Environmental Protection and the US Environmental Protection Agency. The surficial waste primarily appears to be coal purification waste. The chemicals found in the waste include sulfur, lead, cyanides and naphthalene. The site has two distinct waste layers separated by one foot to two feet of sandy material. The top layer consists of purification waste and is approximately two feet in thickness. The lower layer contains coal ash/ coal tar like materials and varies from six inches to one foot in thickness. Analysis of this material showed the presence of Polycyclic Aromatic Hydrocarbons, and that this waste is a non-hazardous waste. Mobil excavated the top two feet layer of visually contaminated wastes and all underlying stained soils from the site to the depth of groundwater. The excavated soils were shipped off-site for disposal and the excavated areas were backfilled by two to three feet of clean soil and covered by cement concrete and/or asphalt layer. Groundwater is five feet below grade and is shown to be saline. After soil removal, a groundwater monitoring program was undertaken and indicated no contamination. Following Site remediation, Mobil built a new gas station which is in operation. Department's involvement is not required.
