Project

Chelmsford, MA

As part of the American Recovery and Reinvestment Act (ARRA), Nobis was selected to provide the EPA with Brownfield Assessment Services for the site in 2010. 

Nobis was subsequently retained by the Town of Chelmsford in 2011 to provide demolition oversight under a $200K EPA Cleanup Grant. In addition, the Town was awarded SARRS funding from MassDEP. As the designated SARRS contractor, Nobis is conducting MCP Phase II investigations. The Town has also been awarded funding from MassDevelopment to conduct LSP services.

The State of Massachusetts selected the site as a Brownfields Support Team (BST) Initiative site.

The approximate 3-acre property is currently vacant and was formerly used for electronics manufacturing from the 1960’s through the early 2000’s. The Town of Chelmsford acquired the Site in 2006.

Levels of chlorinated volatile organic compounds (CVOCs) were detected in the Town of Chelmsford Riverneck Road drinking water wells in 1980. The Massachusetts Contingency Plan (MCP) Disposal Site includes the Site Property at 27 Katrina Road and off-Property locations to the east/southeast, including the Riverneck Road well field. The source of groundwater impact at the Disposal Site is attributed to the former use and storage of solvents during manufacturing operations at the Site.

On behalf of EPA, Nobis performed a Hazardous Materials Survey of the warehouse building for Asbestos, Lead Based Paint and Hazardous Materials. Nobis also performed a groundwater monitoring well inventory, drilling oversight and groundwater sampling to further delineate site impacts to groundwater and assess the nature and extent of CVOC-impact. Despite historic operation of a groundwater recovery and treatment system and limited soil excavation, the source of CVOCs appears to be soils located beneath the Site building. Source remediation requires building demolition to access CVOC and petroleum-impacted soil and groundwater. 

On behalf of the Town, Nobis is managing building demolition, including investigation of TSCA-regulated PCBs under the EPA Cleanup Grant. PCBs will be managed under a Self-Implementing Plan (SIP). On behalf of the Town, Nobis is providing LSP Services. Nobis is conducting a comprehensive MCP Phase II investigation on behalf of MassDEP to include extensive soil, groundwater and surface water sampling throughout the site.

The Nobis Project Manager and LSP serve on the BST Initiative Site Team with the Town of Chelmsford, EPA, MassDEP and MassDevelopment.
