Connecticut – KNOW about the Environment

Connecticut currently has fourteen sites listed on the National Priorities List (NPL). The Environmental Protection Agency (EPA) assesses each site on the NPL and a course of action is decided. The EPA’s goal is to control and contain human exposure to harmful contaminants at the locations listed on the NPL. The EPA decides the best remedial solution to control the contamination problems, and then constructs the necessary resources. After the construction of the final remedial measures, the EPA continues to test the various sites to ensure that the contamination is under control and the applied corrective measures are effective. The following locations are currently listed on the NPL and currently have an unsafe or undetermined level of human exposure to contaminants and containment of contaminated gas or groundwater.

Durham Meadows (Durham, CT) is under construction. The final remedial measures were decided in 2005 and construction began in 2010. The current environmental hazards the site poses rests in the contamination of groundwater with volatile organic compounds (VOCs). Currently, the EPA is in the process of collecting data to see if the water vapor from this contaminated groundwater creates an unsafe level of human exposure. Methods have been implemented to control the migration of contaminated water and safe alternative water sources have been found for the local community. Despite these improvements, the site remains on the National Priorities List, and will remain on the NPL until more efficient methods of controlling and regulating contamination, such as the removal of contaminated soil and the installation of a water monitoring system, have been effectively established.

The Linemaster Switch Corp. (Woodstock, CT) is currently categorized by the EPA as having an unknown level of human exposure to contaminants. Remedial construction has been completed, including a groundwater extraction and treatment system. In 2011, sampling was performed to check the human exposure safety levels to the air and groundwater at the site. The testing checked specifically for levels of volatile organic compounds (VOCs) and the contaminant, 1,4-dioxin. The results of these tests will be taken into account in an official review of the site, which is to be completed in 2012.

Raymark Industries, Inc (Stratford, CT) has created an unsafe level of human exposure to contaminants in many areas of Stratford, CT. People are able to come into contact with soil contaminated with lead, asbestos, PCBs, and other contaminants. The EPA has spent roughly $200 million to clean up and control level of human exposure to contaminants caused by Raymark Industries, Inc. No final cleanup measures have been determined, but temporary cleanup measures, such as waste removal from residencies and the installation of ventilation systems, have been initiated to increase the safety of Stratford residents. The site has been on the National Priorities List since 1995.

The Scovill Industrial Landfill (Waterbury, CT) has been on the National Priorities List since 2000. There is not a threatening level of human exposure contaminants at the site, as buildings or pavement mainly covers contaminated areas. However, contaminated groundwater migration is not under control. Due to budget constraints, an initial cleanup of the site has not yet been initiated, but is scheduled to proceed in June 2013.
