  • Immediate Response Actions - Residential Property, Sutton, Massachusetts
    Cushing, Jammallo & Wheeler is providing Licensed Site Professional (LSP) services, on behalf of the homeowner, for a release of approximately 4,000 gallons of #2 fuel oil that occurred over a number of years. CJW conducted initial assessment activities to determine the extent of the release and determined that oil had migrated through the foundation drainage system onto an adjacent property. CJW conducted short term response actions aimed at controlling indoor air exposures to enable the homeowner to stay in the residence while additional response actions were planned. CJW conducted additional assessment activities to further identify the extent of soil and groundwater impacts. CJW worked with the responsible parties to design and price remediation plans while maintaining compliance with the requirements of Massachusetts environmental regulations.

    CJW supervised the execution of the remedial plans which involved the relocation of the residence and the excavation and off-site recycling of approximately 3,000 cubic yards of petroleum-impacted soils. The removal action included the excavation of soils to a depth of approximately 15 feet beneath the residence and the complete replacement of the foundation drainage system. CJW screened/selected specialized contractors needed for the house relocation (house mover, geotechnical engineering, etc.) and supervised the backfilling of the excavation. The house has been moved back to its original location on a new foundation without significant structural damage to the house.

    Response actions on this program are continuing. CJW has implemented additional cost saving measures, such as utilizing less costly, off-site soil facilities commensurate with receiving the degree of soil contamination.

  • Class A-2 Response Action Outcome - Residential Property, Watertown, Massachusetts
    Cushing, Jammallo & Wheeler provided Licensed Site Professional (LSP) services and supervised the response actions at a 3-story residence where a sudden release of approximately 230 gallons of #2 fuel oil occurred in the basement. Because of the coarse sand and gravel soils beneath the residence, the release penetrated to a depth of approximately 17 feet below grade. As such, it was necessary to utilize an extensive structural support system to enable the removal of petroleum-impacted soils. This included the placement of temporary support structures around existing structural members, followed by the excavation of petroleum-impacted soils and the replacement with new structural members. In addition, CJW removed petroleum-impacted soils beneath the existing field-stone foundation and chimneys to depths of 12-14 feet below grade through the use of controlled excavation and the placement of new concrete supports. At the completion of the program, approximately 311 tons of petroleum-impacted soils were removed for off-site recycling. The response actions were successfully completed without significant structural damage to the three story residence.

    CJW supervised the restoration of the basement floor and new supports for existing heating boilers. Throughout the course of the response actions, CJW conducted extensive ventilation of the living areas of the residence. Combined with the extensive soil removal activities, these actions enabled CJW to demonstrate that petroleum hydrocarbon concentrations in indoor air were in compliance with MADEP indoor air threshold values so that the residents could re-occupy the house without extensive response actions in the living areas.

  • Releases of Mineral Dielectric Fluid from Pole- and Pad-Mounted Transformers and Other Services - Reading Municipal Light Department, Reading, Massachusetts
    Since 2002 , Cushing, Jammallo & Wheeler has been under agreement to provide environmental consulting services to this utility. CJW has responded to and provided LSP services for numerous releases of mineral oil dielectric fluid (MODF) from both pad-mounted and pole-mounted transformers throughout the Reading Municipal Light Department's service area which includes Reading, North Reading, Lynnfield, and Wilmington, Massachusetts. For the majority of the historical releases, appropriate assessment and cleanup activities lead to rapid and successful completion of Limited Response Actions (LRAs) such that the releases did not have to be reported to the Massachusetts Department of Environmental Protection (MADEP) under the MCP. Other sudden releases, requiring notification to the MADEP, resulted in successful closed out via Class A-1 or A-2 Response Action Outcomes (RAO) under the MCP (e.g., no Activity and Use Limitation was necessary to reach a level of No Significant Risk).
