Please make a note.

The nearly 41-acre Beede Site is located in a residential Plaistow, NH, neighborhood that was served entirely by private potable water supply wells. Twenty-two residential water supply wells were historically found contaminated and placed on Point-of-Entry treatment systems until 2013 when a water supply line was constructed to supply alternative water. The facility operated from the 1920s through August 1994 as a waste oil storage and recycling facility. The Site is contaminated primarily with waste oil that seeped into the ground from a variety of sources, including a former unlined lagoon, underground storage tanks, above ground storage tanks, and numerous drums located throughout the property. The Site was added to the NPL in December 1996. The principal threats to human health and the environment are direct contact and ingestion of polychlorinated biphenyls (PCBs) and lead in shallow soil, ingestion of VOCs in the deep soil, and ingestion of VOCs in the groundwater. Low-level threats to human health are posed by exposure to PCBs and PAHs in a very limited area of Kelley Brook. Low-level threats to ecological receptors are posed by exposure to VOCs and PAHs in the surface waters of Kelley Brook.

Cleanup Approach
[Back to Top]

Following several initial response actions at the Site, the final cleanup will be addressed in one phase for groundwater and three sequential phases for soils (as described in the 2004 Record of Decision (ROD): groundwater management of migration - groundwater extraction and treatment began in November 2013; Phase 1 soils using thermally enhanced (steam) soil vapor extraction of deep soils within former lagoon area - treatment operations were initiated in April 2015 and will continue through November 2015; Phase 2 soils using thermally enhanced (steam) soil vapor extraction of deep soils within former above ground and underground tank area, including landfill and sediment excavation, with planned treatment to begin in April 2017 and run through November 2017; and Phase 3 soils by excavation and off-site disposal of the contaminated shallow soils. Completion of this final phase of the overall cleanup approach (i.e., shallow soil excavation) is presently planned to be completed by December 2018.

Initial Action Several initial response actions have been taken at the site - please refer to the History and Response link provided below.

History and Response http://www.epa.gov/region01/

MOM Design Approved in September 2012

MOM Construction Started in December 2012 and completed in October 2013.

MOM Start of Operation Groundwater extraction and treatment operations started in November 2013.
The system is designed to reduce plume migration and improve groundwater quality. It employs seven extraction wells averaging approximately 130 gallons per minute. The extracted water is treated via microfiltration for metals (iron, manganese and arsenic) and for 1,4 dioxane and other VOCs through an advanced oxidation process, before being discharged to the groundwater via two rapid infiltration basins and five injection wells. These on-site discharge components help maintain the water balance in and near Kelley Brook. The system is overseen by a contractor with both on-site and remote monitoring and control capabilities. The building is heated primarily through the use of geothermal techniques.

As of February 2015, over 67 million gallons of contaminated groundwater have been extracted, treated and discharged into the rapid infiltration basins and/or injection wells. A portion of the water treated through the MOM system is, as of April 2015, routed to the Thermal Treatment operations and supplies water to produce the steam. Water extracted from the ground at the Thermal treatment system is pre-treated and then discharged back into the MOM system.

Concentrations of contaminants in monitoring wells will continue to be monitored for the quality of groundwater, as will surface water in nearby Kelley Brook. Monitoring of both the formerly impacted residential wells as well as those not impacted but in close proximity will continue either on a yearly basis or every three years.

Soil Cleanup and schedule: The remedy calls for cleanup of parcel 1 soils using thermal treatment as well as excavation/disposal. The soils will be addressed sequentially and in three Phases Thermal Treatment of Residual Materials using steam enhanced vacuum extraction:
Phase 1 (April 2015): within deeper soils of the former lagoon area
Phase 2 (~April 2017): within deeper soils of the former tank storage area

The combination of Phase 1 and Phase 2 activities will address approximately 70,000 yd3 of contaminated soil (greater than 10 ft below ground surface), by removing contaminants found in the residual oils which could continue to leach into the groundwater above drinking water standards.

Excavation and Off-site Disposal of Contaminated Soils:

Phase 3 (~2017-2018): Excavation and off-site disposal of approximately 77,000 yd3 of the contaminated shallow soils (within the top 10 feet of ground surface) within the Parcel 1 property , including all remaining soil piles, landfill materials and contaminated sediments; followed by backfill with clean fill and site grading.

2015 Remedial Design/Remedial Action: Phase 1 Thermal treatment using Steam Enhanced Vacuum Extraction The Final Remedial Design for the first phase of thermal treatment using steam enhanced extraction (SEE) of residual oils found in soil at depth under the former lagoon area was approved by the EPA in February 2015. Construction for this treatment operation began in the spring of 2014 and was completed in April of 2015. The treatment operations began in April 2015, and will continue until VOC levels in the deeper soils attain the required cleanup level and no longer represent a continuing source of contamination to groundwater, anticipated to require approximately 150 days of operation, consistent with the 2004 ROD.
As part of the SEE treatment system, steam will be injected into the subsurface at several depths to facilitate mobilization/migration of the residual oils into the groundwater and as vapors, with subsequent migration of these liquids and vapors towards multi-phase extraction wells. Based on the contaminant composition at the Site, it is expected that as much as 70-80% of the mass to be removed will be recovered in the liquid state, and the remaining 20-30% as vapors. The extracted contaminants will be collected for eventual disposal. The extracted water will be pre-treated near the SEE system and then pumped to the larger MOM system for final treatment. The vapor phase contaminants are collected and will be destroyed (reduced to carbon dioxide and water) in a gas-fired thermal oxidizer, before air and steam discharge to the atmosphere.

A portion of the water that is treated by the MOM system will be used to supply water for steam generation. A natural gas line was brought down Kelley Road to supply the energy to the SEE system for steam generation and the thermal oxidizer.

Operational update: Biological growth, along with salts and metal precipitates (iron and manganese ) have caused fouling within the SEE treatment process causing maintenance issues in the MOM system. Subsequently, on June 19, 2015 NHDES approved a temporary discharge permit of the SEE pre-treated waters to be discharged to rapid infiltration basin (RIB) B to allow the thermal treatment to continue until the fouling issues are resolved within the pre-treatment system, and to maintain hydraulic capture and treatment within the MOM system.

Community notes: There is vehicular traffic during equipment delivery and construction, however there will be minimal vehicular traffic required during the operation of the treatment system.

Slats installed in the former Kelley Road entrance will limit visual impacts to neighbors, and a noise barriers have been installed near the equipment. Steam being released to the atmosphere from the stack of the thermal oxidizer, will be visible. Ambient air sampling data collected during thermal treatment operations to date have indicated non-detect or levels far below 24 hour acceptable air levels.

2017 Remedial Design/Remedial Action: Phase 2 Thermal treatment using Steam Enhanced Vacuum Extraction The Remedial Design for the Phase 2 Thermal activities will continue as operation of the Phase 1 Thermal treatment system proceeds. A pilot test for the Phase 2 steam injection portion of the design is scheduled to happen in the fall of 2015.

2017 Remedial Design/Remedial Action: Phase 3 Excavation and off-site Disposal The Remedial Design for the Phase 3 excavation and off-site disposal activities will follow implementation of the Phase 2 Thermal treatment.

Enforcement HighlightsA Remedial Design and Remedial Action Consent Decree was entered by the court in July 2008.

Environmental Progress
[Back to Top]

The EPA issued a Record of Decision (ROD) for the Site in January 2004 and an ESD in 2012. The cleanup plan selected in the 2004 ROD calls for 1.) the excavation and off-site disposal of contaminated shallow soils, the on-site landfill and contaminated sediment from Kelley Brook, as well as numerous soil piles; 2) treatment of contaminated deep soils of parcel 1 using thermally (steam) enhanced soil vapor extraction technology; 3) contaminated groundwater extraction and on-site treatment and discharge; 4) land and groundwater use restrictions; and 5) long-term monitoring of groundwater, surface water and sediment. The 2012 ESD allowed for the installation of a water-line to supply drinking water to residential properties impacted by Site contaminants and which had been utilizing point-of-entry treatment systems.

Current Site Status

The Performing Settling Defendants have been conducting pre-design and design activities since the 2008 Consent Decree was entered. A 30% Remedial Design Report for the entire remedy was submitted to the EPA in December 2010. A 100% Remedial Design Report for the MOM component (groundwater pump and treat) of the remedy was approved in September 2012. Off-site trucking of about 565 truck loads of contaminated soil started in late February 2013 to allow for construction of the MOM system with the new access road. Construction of the MOM component of the remedy started in December 2012 and operation of the system started in November 2013. Also in 2013, a waterline was constructed to the affected residential properties near the site in accordance with the 2012 ESD. The MOM system is expected to continue to operate until 2033, or beyond, (15 years of operation following removal of sources to reduce groundwater to drinking water standards). The three (3) remaining design phases for soils are planned to be submitted in sequence over several years. The Remedial Design for the Phase 1 of thermal treatment was approved in February 2015. Construction of this system started in May 2014 and following startup activities in April 2015, the system began operations in May 2015 towards the 150 days of thermal treatment operations. A public meeting for this system operation was held on March 24, 2015 at the Plaistow Public Library. As of July 13, 2015 the Thermal SEE system has operated for 58 of the 150 days expected and over 5,000 gallons of residual oils have been removed from the subsurface.

The remedial design for the second phase of the thermal treatment will continue as operation of the Phase 1 thermal treatment system proceeds. The Final remedial design for the Site soils will be submitted following the completion of the second phase of thermal operations.
