Circuitron Corporation manufactured circuit boards on this one acre site from 1961 to 1986. In 1986, the company vacated the facility. The site is in a densely populated industrial and commercial area of Long Island. The property was owned by 82 Milbar Boulevard Corporation. Circuitron was a subsidiary of FEE Industries, which ADI Electronics, Inc. bought in 1984. The circuit board process at the facility included drilling, screening, plating, and scrubbing processes, all of which generated chemical wastes. Wastes were reportedly placed in above ground and underground tanks and storm drains. Thousands of gallons of plating wastes were discharged to an underground leaching pool that was licensed under the State Pollutant Discharge Elimination System (SPDES) and to an unauthorized leaching pool beneath the floor of the plating room.
Approximately 15 municipal wells serving local residents are located within three miles of the site and serve over 215,000 people. The nearest well is located within 1,300 feet of the site and is in the path of the groundwater flow. A shallow well, which could be used for drinking water, has been closed since 1978 due to contamination.
This site is being addressed in three stages: an emergency action and, two long-term remedial phases, which focus on remediation of contaminated groundwater and cleanup of the contaminated soils, sediments and building.
The emergency actions taken included the removal of chemical containers, drums and storage tanks that contained hazardous materials. Additionally, the cleanup and disposal of the contaminated soil, debris, and site sediments further reduced the potential for exposure to contamination at the site and minimized the possibility of further cross media contamination of groundwater.
Construction of the groundwater treatment system was initiated in September 1999 and completed in September 2000. The groundwater extraction and treatment facility operated as part of EPA’s long-term response actions at the site. The groundwater extraction and treatment facility had treated approximately 90 million gallons of groundwater from September 2000 until it was shutdown in August 2007. In March 2008, EPA began operation of a single integrated groundwater circulating well with an in-well vapor stripping and soil vapor extraction (GCW/IVS/SVE) system to address the remaining contaminated subsurface soils and groundwater located in the southwest corner of the site. EPA operated the GCW/IVS/SVE system until June 2011 when operation of the system was transferred to the New York State Department of Environmental Conservation (NYSDEC). NYSDEC will continue to operate the system until the soil and groundwater cleanup goals are achieved.
Currently, the site is conducting its third five-year review and its purpose is to ensure that the implemented remedies at this site function as intended and continue to be protective of human health and the environment. It is anticipated that the five-year review will be completed by December 2014.
