Background

The site at 415 East Prairie Ronde Road in Dowagiac, Michigan has been used for a variety of manufacturing purposes since 1916, including production of furnaces, copper tubing and air conditioners. Prairie Ronde Realty (PRR) purchased the property in 1995 and leased it to National Copper Products which used it for manufacturing. In 2009, National Copper Products filed for bankruptcy. The building is currently leased to multiple entities for non-industrial uses.

Groundwater at the site is contaminated with volatile organic compounds (VOCs), primarily trichloroethene (TCE).

PRR entered into a RCRA 3008(h) Administrative Order on Consent (AOC) with EPA on June 2, 2006. PRR must implement site-wide corrective action at the site. EPA has been overseeing the environmental investigation at the 33-acre facility and will propose appropriate remedies in those areas where contamination must be addressed.

In 2012, EPA collected indoor air samples and on-site sub-slab samples (from the space under the building foundation). Samples demonstrated that TCE concentrations below the building foundation and within the indoor air exceeded EPA's screening levels. TCE easily evaporates as a gas when it is exposed to air or soil and migrates from below the building to inside the building, a process referred to as vapor intrusion. EPA directed PRR to decrease the immediate concentrations of TCE inside the building with proper ventilation and to establish a permanent vapor mitigation system.
