Site Facts

This site covers approximately 423 acres, two-thirds of which is occupied by a manufacturing complex with more than 50 buildings. The land use in the area is a mix of industrial, commercial and residential. IBM is located approximately six miles south of the City of Poughkeepsie between Route 9 and the Hudson River.

IBM at Poughkeepsie is involved in manufacturing, assembling and testing large business machines, primarily computers. The manufacturing process involves the cleaning of electric components with solvents; electroplating; photoetching; degreasing, and soldering of components. In addition, research chemical laboratories owned and operated by IBM are located on-site. As a result, IBM generates fifty separate waste streams that are Resource Conservation and Recovery Act (RCRA)-regulated, and an additional five PCB-waste streams regulated by New York State Department of Environmental Conservation (NYSDEC).

Due to accidental releases, breaks in underground pipes and past waste management practices, there have been releases to both soils and groundwater. The most serious releases are volatile organic compounds (VOCs) to the groundwater in the manufacturing area of the plant. This release has resulted in the Site Gravel groundwater plume.

The Site Gravel plume extends from beneath the manufacturing buildings to Spring Brook (also classified as stream H-107). This plume is located underneath a continuous gravel deposit in the southern part of the main plant at a depth of approximately 30-50 feet. This plume extends from approximately 400 feet east of Building 012, underneath buildings 002, 004, and 008 to intersect the surface at Spring Brook.

Like the majority of the site, the Site Gravel is underlain by saturated bedrock with relatively low groundwater storage and transmitting capabilities. Since Spring Brook discharges into the Hudson River, there is a potential for off-site migration.

Currently, surface water monitoring along Spring Brook continues at seven wells and there has been a substantial reduction in the amount of trichloroethylene (TCE) from the Site Gravel plume entering H-107. TCE was reduced from an average 40 ug/l in 1990 to 18 ug/l in 2013. Most releases to soils were immediately cleaned up by the facility and, where questions remained, additional soil sampling and analysis were conducted under RCRA authority.

Site Responsibility and Legal Instrument

New York State Part 373 Hazardous Waste Management Permit regulates compliance of RCRA storage and management of hazardous waste in containers and storage tanks, and corrective action including investigative studies, groundwater monitoring, and interim/final corrective measures.

Potential Threats and Contaminants

There were three principal solvents used at the Poughkeepsie facility that have been detected in dissolved form in the groundwater in the shallow sand aquifer beneath the site. These solvents contain volatile organic compounds (VOCs). The most widespread concentration of these contaminants is in the Site Gravel plume, which originated largely from activities in the manufacturing area of the plant site. While there are multiple contaminant plumes at the site, they are being remediated and controlled on-site.

The RCRA Facility Assessment/Site Visit (RFA/SV) and sampling activities were performed for soils at nine solid waste management units (SWMUs) in 1998, and the RCRA facility investigation (RFI) was completed in March 2000.

Based on the results of IBM's Risk Management Initiative's evaluation of the potential threat to human health, the concentration of chemicals in surface and subsurface soils and groundwater underlying the site do not pose unacceptable risks. The site is being currently investigated for soil vapor intrusion and indoor air issues to determine if there are unacceptable risks for office workers or facility personnel.

 There is a potential for surface water impact to the Hudson River, which is a Class A river, meaning that it has been determined by NYSDEC that its best use is as a source of drinking water. The City of Poughkeepsie withdraws its water from the Hudson River approximately 5 miles from the IBM facility.

Cleanup Approach and Progress

The site remedial (corrective action) strategy consists of the following two tasks:

The RFA/SV completed in 1992, has determined that several units had releases to soil, groundwater and surface water. As a result, IBM was required to conduct an RCRA Facility Investigation (RFI) at thirteen Solid Waste Management Units (SWMUs) to evaluate the nature and extent of the contamination. Soil sampling was conducted at eight SWMUs to confirm whether releases had occurred.

Several interim corrective measures have been implemented to mitigate the impacts of releases since the late 1970s, among them the tank farm pump and treat system, the former equipment crusher release pathway asphalt cap, and Building 003 passive groundwater collection system. Also, soil, wastes and containers were removed from the location of a previous on-site waste disposal area that was located west of Building 208. Historically, tanks that IBM utilized to store chemicals located in the lower plant area adjacent to the Hudson River, leaked. In response, soil and water containing these chemicals were removed down to the bedrock. An underground slurry wall was installed to prevent groundwater movement from the immediate area of the spill.

From 1981 to 1986 an extraction system operated near a former burn pit to depress the water levels and to remove light non-aqueous phase liquids (LNAPL) found at several groundwater monitoring wells in this area. In addition, another extraction system to remove residual LNAPL has been operating intermittently since late 1997. LNAPL containing xylene in the soil and water was removed from an area where a former tank farm was located, which was west of Building 004.

Old industrial sewers suspected of leaking were upgraded to a new double-walled system with leak detection. Sediment in some pipes and soil around these leaking pipes and manholes were considered to be potential continuing sources. Sediment was flushed from the pipes and in several instances, piping and manholes were removed, together with surrounding soil.
Long term groundwater extraction has proceeded at two wells at the Site Gravel area to control the migration of volatile organic compounds (VOCs) to the on-site stream.  The New York State discharge standard for trichloroethylene (TCE) is 21 parts per billion and the latest IBM monitoring results for this stream show less than 18 parts per billion. While this is within State guidelines, there are sporadic fluctuations and exceedences. That stream is a tributary to the Hudson River. These two extraction wells have removed approximately 1,000 pounds of volatile organic compounds to date.

As for the on-site groundwater monitoring levels, well T-34 near Building 1 shows up to 7,500 ppb of TCE according to the 2012 Annual Report submitted on April 29, 2013.  The estimated total flux of VOCs loadings into the Hudson River is 0.00933 pounds per day.  
 
Another interim corrective action, the storm sewer re-routing project, was implemented to segregate storm water from groundwater, which had previously collected in the storm sewer system through infiltration. In the area where this storm sewer re-routing was implemented, groundwater containing volatile organic compounds was infiltrating into the old storm sewer system. The re-routing was performed to prevent continued infiltration.

As part of the interim corrective measures program, the former equipment crusher lower release pathway that is contaminated with semi-volatiles was paved with asphalt to prevent direct human contact. A groundwater interception system was completed in the area adjoining the Hudson River involving the former burn pit area, antenna drum storage, former Building 025, waste oil leach field, Building 077 and the overpass area in 2001. This project was designed to capture five separate contaminated groundwater plumes before any of them enter the Hudson River.

EPA and NYSDEC have evaluated the effectiveness of the groundwater containment system. This evaluation demonstrated that the migration of contaminated groundwater was under control. In addition, a treatment facility was constructed in Building 030 to handle the captured water.

An Indoor Air mitigation system was installed in Building 3 reducing the levels of TCE from more than 600 ug/m3   to 3.7 ug/m3 (the NYSDOH acceptable level is 5 ug/m3).  
The interim corrective measures were incorporated as final remedies under a Part 373 permit.
