| Description of geology/hydrogeology | Depth to the water table ranges from 0 to 10 feet below ground surface (bgs) throughout the Site. Groundwater in the unconfined overburden aquifer flows east and southeast toward the Quinnipiac River. Groundwater in the semi-confined bedrock aquifer primarily flows in the upper fractured zone, but may also travel in deeper portions of the rock. Flow in the bedrock is also east and southeast towards the Quinnipiac River. The overburden aquifer is primarily recharged by precipitation. Recharge to the bedrock aquifer is also primarily by precipitation. Water table immediately to the west and upgradient of the Operations Area lies within the bedrock. Some flow between the aquifers occurs in portions of the Site where the till is especially thin or absent. The direction of flow and the rate of recharge vary in response to seasonal fluctuations. | |
| Cleanup goals or remedial objectives | The U.S. Environmental Protection Agency’s (EPA) Superfund Record of Decision (ROD) dated September 30, 2005 indicates that performance standards equivalent to a 95 to 99% reduction of the NAPL mass within the treatment zone will be established for the thermal treatment system by EPA during Remedial Design phase. Furthermore, the ROD indicates that the objectives of the remedial action at the Solvents Recovery Service of New England (SRSNE) Site are: to mitigate, restore and/or prevent existing and future potential threats to human health and/or the environment from soil and wetland soil, overburden and bedrock groundwater, and NAPL in the overburden and bedrock aquifers; and to attain applicable or relevant and appropriate requirements (ARARs). Specifically, the remedial objectives for soil, NAPL and groundwater in the NAPL area addressed by the thermal treatment system are to: reduce or stabilize contaminants in the NAPL area that would otherwise result in groundwater concentrations that pose a carcinogenic risk in excess of 1 x 10-4 to 1 x 10-6 (a cancer incidence rate of 1 in 10,000 to 1 in 1,000,000 human beings), non-carcinogenic Hazard Index greater than 1, or that exceed ARARs. Site-specific numeric goals for the contaminants of concern are provided in the ROD. In addition to the thermal treatment system discussed in this profile, the remedial action at the SRSNE Site includes other source control and groundwater treatment methods. Further details about the overall site remedy are available in the ROD. | |
| Performance data available? | No | |
| Summary and description of performance data | Information about implementation of the selected remedy following the signing of the ROD is not available in the references cited. | |
| Comments | The remedy selected by EPA to address contamination at this site includes in situ thermal treatment of soils contaminated with waste oils and chlorinated solvents in the Overburden NAPL area beneath the Operations Area. The type of thermal treatment technology to be applied at this site will be selected during Remedial Design. Application of heat to the contaminated subsurface is expected to remove contaminants by volatilizing and converting them from liquid phase to vapor phase. The contaminant vapors emanating from the thermal unit will be captured by a vapor extraction system and directed to a vapor treatment unit onsite. The vapor treatment system will be finalized during design phase but will possibly contain a condensation and recovery unit, a thermal oxidation unit and a scrubbing unit to capture residual vapors using carbon. The treatment area may be covered with a temporary cap to minimize the potential for release of contaminant vapors. This soil remedy represents a portion of the overall site remedy documented in the September 2005 ROD. | |
