EPA RCRA ID: MDD044147098
The Resource Conservation and Recovery Act (RCRA) is the public law that creates the framework for the proper management of hazardous and non-hazardous solid waste. Corrective action is a requirement under RCRA that facilities that treat, store or dispose of hazardous wastes, or did so in the past, investigate and clean up hazardous releases into soil, groundwater, surface water and air. For more information, and for more information on RCRA-specific terms used on this page, please visit EPA’s umbrella RCRA web page or EPA’s RCRA Corrective Action page.

Cleanup Activities
Since 2001, Dresser Industries, Inc. (DII) has conducted investigations of contamination in soil, groundwater, and soil gas at the Facility. The investigations have centered largely on investigating release from key features and chemicals associated with former operations, including gasoline constituents, surrogates for gasoline used in the testing of the dispensing pumps (i.e., mineral spirits), diesel fuel, solvents, and metals. In 2001, DII transferred the Facility to Dresser RE, LLC (Dresser), but retained certain environmental responsibilities. In 2010, Dresser removed equipment, structures, and subsurface features from the Facility, revealing additional contaminant impacts to soil and groundwater, which DII subsequently investigated. DII has conducted various interim corrective measures at the Facility including remediation of chromium impacted groundwater and removal of impacted soils, groundwater, light nonaqueous phase liquid floating above the groundwater (LNAPL), and over 25 tanks. DII continues to monitor remaining contaminant impacts to groundwater, measure LNAPL thickness, and recover recoverable LNAPL.
Contamination remains in onsite soils, groundwater, and in the form of residual LNAPL (mineral spirits) that floats above the groundwater.
Two groundwater contaminant plumes extend offsite into deeper groundwater towards the northwest. The western plume is lightly contaminated with a chlorinated solvent (tetrachloroethylene, commonly referred to as "PCE"). The eastern plume is contaminated with the dissolvable fraction of mineral spirits being released from the LNAPL. There is no known current exposure to either plume.
Recent activities have focused on determining remedial objectives and evaluating a remedy for the remaining contamination.
Over the last couple of years, DII has submitted various documents in support of selecting a remedy. EPA is reviewing these documents.
DII continues to monitor remaining contaminant impacts to groundwater, measure LNAPL thickness, and recover recoverable LNAPL.
Cleanup Background:
Since 2001, DII has conducted numerous investigations of contamination associated with release from former operations at the Facility.
In 2009 and 2010, the current owner, Dresser, removed equipment, structures and subsurface features from the Facility, including subsurface pipes wrapped with covered asbestos, foundations, and other subsurface features.
Thereafter, DII conducted investigations of additional impacts to soil and groundwater. Polychlorinated biphenyls (“PCBs”) were found in certain surface and subsurface soils. Hexavalent chromium was found in certain soils and groundwater beneath the Facility. Mineral spirits were found in certain subsurface soils and as a light non-aqueous phase liquid (“LNAPL”) in certain monitoring wells screened across the water table. Two groundwater plumes were found to extend offsite into deeper groundwater, a western plume containing PCE and an eastern plume containing the dissolvable fraction of mineral spirits from the LNAPL.
DII has implemented various interim corrective measures, including (1) batch extraction of groundwater containing hexavalent chromium; (2) in situ treatment to remediate hexavalent chromium in groundwater (via in-situ reduction of hexavalent chromium to the insoluble form of trivalent chromium); (3) removal of LNAPL from monitoring wells with recoverable amounts of LNAPL; and (4) removal of impacted soils from certain areas at the Facility, including soils that contain chromium, PCBs, PCE, and PAHs
Cleanup Actions or environmental indicators characterizing the entire facility are shown below. This listing, and all the data on this page, come from EPA’s RCRAInfo and are refreshed nightly to this page. For this table, a blank in the Status column could mean the action either has not occurred or has not been reported in RCRAInfo.

Facility Description
Link to a larger, interactive view of the map.
Industrial operations took place at the Facility from approximately 1938 until 2001. The former manufacturing plant initially may have operated as a machine shop, but it is primarily known for its manufacture of fuel dispensing pumps for both domestic and international markets. Hoists for trucks and buses were also manufactured at the Facility for a limited period of time. During the manufacture of pumps, mineral spirits were used to test the pumps. During the manufacture of hoists, the hoists were chrome plated in chrome plating baths in deep pits. During the history of operations at the Facility, various wastes were reportedly generated including wastewater treatment effluent and sludge; used petroleum hydrocarbons; spent solvents from equipment cleaning; paint-based solids and sludge; and corrosive liquids and sludge from metal pre-treatment and coating operations.
From approximately 1960 to the late 1990's, a parcel of land located on the north side of West College Avenue and consisting of approximately 8.65 acres was used as a parking lot for employees. In the late 1990s, this parcel was sold and redeveloped as a shopping center.
In approximately 2001, the remaining Facility was transferred from Dresser Industries, Inc. (DII) to Dresser RE, LLC (Dresser). An affiliate of the Salisbury University Real Estate Foundation has since agreed to purchase the Facility, subject to certain closing conditions. The property currently owned by Dresser consists of the following parcels: approximately 16.4 acres comprising the Former Manufacturing Plant and the East Parking Lot properties, and the South Parking Lot property (approximately 1.66 acres).
Releases of gasoline, diesel fuel, solvents, mineral spirits, PCBs, metals and nitrates have been found soils and/or groundwater at the Facility. Various historical releases occurred in connection with the use and handling of petroleum products (e.g., waste oil and mineral spirits) and other volatile organic compounds (“VOCs”). Chlorinated solvents [tetrachloroethylene ("PCE") and trichloroethylene ("TCE")], metals (hexavalent chromium and lead), petroleum constituents (benzene, toluene, ethylbenzene, trimethylbenzene, and naphthalene) and nitrate have been found in groundwater beneath the Facility. An area of LNAPL consisting of mineral spirits has been observed in on-site soils and certain monitoring wells in the northern portion of the Facility. PCB contaminated soils were delineated and removed. Hexavalent chromium contaminated groundwater was delineated and remediated via reducing the hexavalent chromium to the insoluble valence state of trivalent chromium. Asbestos used to insulate subsurface pipes (covered with an external jacket) was removed in accordance with applicable regulations as part of the demolition process.
Institutional and Engineering Controls at this Facility
EPA anticipates that it will require the implementation of institutional controls as part of its final remedy for the Facility.
Institutional and Engineering Controls help ensure human exposure and groundwater migration are under control at a cleanup facility. Where control types have been reported by states and EPA in EPA’s RCRAInfo, they are shown below. Not all control types are needed at all facilities, and some facilities do not require any controls. Where there are blanks, the control types may not be needed, may not be in place, or may not be reported in RCRAInfo.
