Site History • Brass Foundry on site in early 20 th century • Metals Plating Facility from 1950’s (as Coastal Metals since 1970) • Plating operations ceased in 2002, building abandoned with liquids/chemicals remaining within • Town gains title in August 2013 6
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) • Mass. DEP 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 (Mass. Development) • Soil and groundwater investigation in 2013 (MVPC) • Mass. DEP groundwater sampling in 2014 7
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 8
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 9
