Waste Site Cleanup & Reuse in New England

Henry's Dry Cleaners

The Henry's Dry Cleaners (Henry's) Site at 36 Pleasant Street in Laconia, NH is currently an active dry cleaner business. The one story building was built in 1946 and is bordered by Pleasant Street to the north, a property owned by Goodwill Industries to the south and east, and the Laconia Savings Bank property to the west. Beacon Street West Condominium (BSWC) is located across the street from Henry's.

From 1986 to 2006, several rounds of groundwater samples were collected from existing monitoring wells located on BSWC where the former Allen-Roger Mill once operated. The water samples detected tetrachloroethene (PCE) at levels above the NH groundwater standards. The NH Dept. of Environmental Services (NHDES) believes that a potential source of PCE contamination is located off site. Since 2007, NHDES has been working to conduct several indoor air sampling surveys at one of the two occupied BSWC buildings. In 2009, groundwater and soil samples were collected from the Henry Dry Cleaners property. PCE and other chlorinated volatile organic compounds were detected in the samples which suggested a historic release may have occurred at or near Henry's.

In March 2012 EPA conducted sub-slab sampling at BWSC. Soil gas screening levels at the Henry's Dry Cleaners and the adjacent Goodwill property exceeded the NHDES levels of concern. No residential samples in the BWSC exceeded the NHDES screening levels. EPA took sampling as part of a groundwater contamination study. Based on the findings of the investigations, EPA believes that there is a PCE source at or near Henry's Dry Cleaners feeding the contaminated groundwater plume. EPA has installed three sets of wells on Henry's and Goodwill Industries Properties to provide additional information to aid in evaluating treatment options and designing a treatment strategy.
