Possible Re-Opening of Closed TCE Sites in Massachusetts

February 12, 2016

MADEP.pngOn January 28, 2016, the Massachusetts Department of Environmental Protection (MADEP) announced that they will be
re-visiting approximately 200 previously-closed historical trichloroethylene (TCE) sites.  Recent changes in the understanding of TCE’s toxicity and concerns about potential vapor intrusion, particularly to residences, prompted the MADEP to take this unusual step in the interest of public health. 

MADEP to arrange site-specific investigations

At these priority sites of concern, the MADEP will be contacting responsible parties and property owners to arrange site-specific investigations of groundwater, soil gas, and/or indoor air.  Most of these sites are located near Boston.  If the investigation results exceed applicable thresholds, the MADEP may invalidate the previously-submitted closure documentation and require additional investigation and/or remedial measures. Depending upon the results of the initial investigations, the MADEP may expand the testing to another 800 previously-closed TCE sites.
