Health Consultation: Public Health Evaluation of Gas Vent Sampling Data Reports, Old Southington Landfill, Southington, Hartford County, Connecticut. EPA Facility ID: CTD980670806

摘要

The United States Environmental Protection Agency (US EPA) requested that the Connecticut Department of Public Health (CTDPH) review and comment on the Risk Assessment for Gas Vent Data Volatile Organic Compound (VOC) Data-Revision 1.1 dated June 2006, for the Old Southington Landfill Superfund (OSL) Site in Southington, Connecticut. Kleinfelter performed the risk assessment for the Performing Settling Defendants (PSDs). The risk assessment uses measured concentrations of landfill gases from gas vents on the landfill cap and models the concentrations in ambient air on the cap and at nearby residences offsite. In the fall of 2005, CTDPH prepared a Health Consultation for the US EPA which reviewed and commented on the Gas Vent Sampling Data Reports dated December, April, and July of 2002 from OSL (ATSDR 2005a). The gas vent sampling was performed by MACTEC Engineering and Consulting for the PSDs. In the 2005 health consultation, CTDPH requested that gas vent modeling for onsite workers for the Old Southington Landfill site be performed in order to determine whether workers on the landfill cap were receiving exposures to landfill gases that could pose a health threat. The risk assessment report reviewed in this health consultation is the result of this request.
