Site Background:
The FCX-Statesville Site is located at the intersection of West Front Street (Highway 90) and Phoenix Street in the city of Statesville, Iredell County, North Carolina. The Site consists of two properties, the former FCX property and the former Burlington Industries property. Beginning around 1940, Farmers Cooperative Exchange (FCX) began operations formulating, packaging, warehousing, and distributing a variety of pesticides and fertilizers on the former FCX property. From 1991 to 1993, EPA-Region IV conducted a Remedial Investigation/Feasibility Study (RI/FS) which confirmed the presence of soil contaminated with pesticides, and groundwater contaminated with pesticides and volatile organic compounds on the former FCX property. In 1995, a separate RI/FS was conducted to characterize the contamination associated with the former Burlington Industries property.
Cleanup Progress: OU1 remedy change complete; OU2 Remedial Action Complete; OU3 Remedial Action on-going
Contamination associated with the Site is being addressed with Three Operable Units (OU1, OU2, and OU3). A separate Record of Decision (ROD) has been signed for each OU. The OU1 Remedial Action (RA) became operational in 1998, and involved the use of a groundwater pump-and-treat remedy to address groundwater contamination associated with the former FCX property. A ROD Amendment was finalized in 2006 which changed the OU1 remedy from groundwater pump-and-treat to Monitored Natural Attenuation (MNA). The OU2 RA was completed in September 2001. Approximately 15,000 cubic yards of pesticide-contaminated soil were excavated, treated on-site using thermal desorption, and backfilled on-Site during the OU2 RA. The liquid residual generated from the thermal desorption process was treated on-Site using Base Catalyzed Decomposition (BCD), and disposed off-site at an approved facility. Initiated in 2001, the OU3 RA uses a combination of air sparging (AS), soil vapor extraction (SVE), and MNA to address the volatile organic compound (VOC) contamination in soil and groundwater associated with the former Burlington Industries property. Since 2001, AS/SVE has removed approximately 14,000 pounds of VOCs from the soil and groundwater on the former Burlington property.
An Explanation of Significant Difference (ESD) was finalized in 2006 which added Accelerated Natural Attenuation (ANA), or enhanced bioremediation, to the existing OU3 remedy. ANA work began in May 2007 which involved the injection of molasses-like nutrients into the groundwater. The objective of using of ANA at the Site is to speed up the natural degradation processes in groundwater, thereby achieving cleanup of the groundwater in less time. Post-injection groundwater monitoring was conducted in September and December 2007 to assess the effectiveness of the ANA.
A Five-Year Review was completed for the Site in 2006, which documented that the OU1, OU2, and OU3 continue to provide adequate protection of human health and the environment at the Site.
Additional Investigations: Additional Assessment of Groundwater and Soil Vapor
A better understanding on how VOCs behave in the subsurface has led to a new understanding that vapors may migrate from contaminated groundwater into the vapor space in the soil and from there, potentially into buildings. For this reason, El Paso has been conducting an assessment of the soil vapor intrusion (SVI) pathway around the former Burlington plant for the past two and a half years. In addition, El Paso is conducting additional assessment of site-related groundwater contamination and SVI in 2009. EPA will provide more information in this Site Summary once the groundwater and SVI data have been collected and evaluated.
