ESS supervised the completion of more than 100 soil borings/groundwater monitoring wells, conducted soil and groundwater sampling, oversaw test pit excavation, soil removal and ground-penetrating radar surveys, and conducted a methane soil gas survey. The purpose of the soil gas survey was to assess if methane was migrating onto the property from the adjacent former landfill. Three separate Site Investigation Reports were prepared and submitted to the Rhode Island Department of Environmental Management (RIDEM).  Three Remedial Action Workplans and one Closure Report were also prepared and submitted to RIDEM.

Upon completion of the Master Land Use Plan for the campus, a Site Remedial/Development Strategy proposed various management and remedial actions to address site conditions. Management and remedial options proposed included: placement of a soil cover over portions of the site, localized soil removal, risk-based demonstration of acceptability of soil quality at specific parcels, placement of environmental land usage restrictions on other parcels, soil arsenic background demonstration, and preparation of variance requests from RIDEM Remediation Regulations for specific issues.  Some of these proposals are currently being negotiated with RIDEM while some have been completed and are awaiting RIDEM approval.
