Cameron-Cole is currently conducting environmental compliance and reporting activities for a facility impacted with elevated levels of chlorinated Volatile Organic Compounds (VOCs) in a multilayered aquifer system, consisting of Trichloroethylene (TCE), Tetrachloroethylene (PCE), and related constituents of concern. Cameron-Cole has conducted a field RCRA facility investigation and prepared a Soil and Groundwater Corrective Action Plan (CAP) in support of facility closure and is currently preparing quarterly groundwater monitoring reports. Overall project responsibilities since 2006 have included conducting field investigations pilot testing, well installation, soil and groundwater sampling, groundwater flow and transport modeling, remedial screening, and reporting on all aspects of the project.

The proposed corrective measures at the facility consist of an Air Sparging (AS)/Soil Vapor Extraction (SVE) source remediation system to remediate vadose zone soils and the shallow hydrologic zone beneath the site. The groundwater monitoring program consists of well sampling and analysis activities, assessing groundwater elevations and trends, and evaluating the nature, extent, and migration of VOCs in groundwater. Once the planned corrective measures are implemented at the site, the monitoring program will also include AS/SVE system operation and maintenance.

The Soil and Groundwater Corrective Action Plan will be used as the basis for the design and installation of the AS/SVE remedial system to address subsurface impacts to soil and groundwater. When the corrective measures specified in the revised CAP are implemented at the site, the site monitoring objectives will be updated to include soil and groundwater remedial system performance monitoring, data evaluation, computer modeling, and optimization to enhance the effectiveness of the system. This will include monitoring and reporting the operational parameters of the system, as well as identifying the effects on remedial performance, and contaminant fate and transport. The groundwater modeling and solute transport to track remedial performance is based on the constructed MODFLOW/MT3D groundwater flow and fate transport model of the site.
