Site Background:
The ABC One Hour Cleaners Site located in Jacksonville, Onslow County, North Carolina is an on-going dry cleaning facility and it is situated on approximately 1 acre of land. Since operations began in 1954, the chemical Tetrachloroethene (PCE) has been used at the facility as the dry cleaning solvent. Groundwater and soil became contaminated with solvents because of spills, and mishandling of the solvents and solvents' residuals. The facility is located across the street from Camp Lejuene Marines Corps base. Three community wells owned by the Base have been disconnected from the Base's drinking water supply system. The groundwater contamination is associated with the dry cleaners, the contaminated soil underneath the cleaner's building. Approximately 4,000 cubic yards of soil is contaminated and is planed to be treated to control the migration of the contaminants the groundwater. The principal contaminants are chlorinated solvents such as tetrachlorethene (PCE), trichloroethene (TCE), 1-2 Dichloroethene and vinyl chloride. They were detected both in soil and groundwater above safe levels.

Cleanup Progress: Long Term Response Action Underway
The Site is a Superfund fund-lead Site and is being addressed through State and Federal actions as two long-term remedial phases that focus on cleaning up the contaminated groundwater and soil. The groundwater remedy was selected in September 1993. The design of the remedy was completed in the fall of 1995 and includes a pump-and-treat system followed by surface water discharge. Funds to start the groundwater remedial action did not become available until the end of 1996. The groundwater pump and treat system is operating at the Site. The groundwater pump-and-treat system is scheduled to be in operation until ground water clean up goals are achieved.

The soil remedy, which consists of a soil vapor extraction system (SVE) was selected in September 1994, and the design was completed in the fall of 1995. Funds to start the soil remedial action became available until mid 1998. The soil vapor extraction system is operating. The SVE system is scheduled to be operating until clean up goals are achieved.

Additional soil, soil vapor and groundwater sampling was conducted at the Tarawa Terrace (TT) Primary School, located on the Marine Corps Base Camp Lejeune in July 2007.  The data generated from sampling confirmed that currently there is not a soil vapor intrusion threat to residents in Tarawa Terrace or students at the Tarawa Terrace Elementary School and there is no evidence of groundwater impact.

A 5-year review of the chosen remedies was conducted and a final report was approved on August 29, 2003. Most recommendations made as part of the 5-year review were implemented. A few other recommendations are still in the process of been implemented.

The second five year review was completed in Sept. 2008 and concluded that all remedies remain protective of the environment and public health. The recommendations from the initial 5 year review have been implemented.
