Chronology of Environmental Response Actions to Date EPA Removal Action in 2003 Phase I Environmental Site Assessment in 2007 on behalf of MVPC (EPA Brownfields Assessment Grant) MassDEP groundwater sampling in 2008 Geophysics Investigation in 2009 (MVPC) Soil and groundwater investigation in 2010 (MVPC) Hazardous Building Survey in 2010 (MVPC) Underground Storage Tank Removal in 2011 (MassDevelopment) Soil and groundwater investigation in 2013 (MVPC) MassDEP groundwater sampling in 2014
Findings of Environmental Response Actions to Date Soil Conditions – Contaminants > Regulatory Criteria Metals Site-wide, highest in operations areas Cyanide at one location Groundwater Conditions – Contaminants > Regulatory Criteria Dissolved-phase metals Site-wide Chlorinated solvents (VOCs) Cyanide Building Condition Asbestos found, particularly roof Deteriorating Significantly
Approach to Site Cleanup Abate hazardous building materials (asbestos) and demolish building Conduct remediation feasibility sampling to fine tune strategy Remove contaminated soils Amend groundwater, if necessary
Bird’s Eye View
