Site Description

The Wrigley Charcoal Site located in Hickman County, TN, consists of four distinct areas: the 35 acre Primary Site, the three acre Storage Basin, the 40 acre Irrigation Field, and the three and one-half acre Athletic Field. The Primary Site was used for industrial operations such as producing iron, charcoal, and wood distillation products intermittently from 1881 to 1966. The Storage Basin and Irrigation Field were utilized for the disposal of contaminated Site wastewaters beginning in the 1940s and continuing until the mid-1960s. Slag and soils derived from the Primary Site were utilized to fill the Athletic Field from 1938 to 1950 when the field was opened. The leachate and wastes at the Primary Site and Storage Basin contained volatile organic compounds including toluene, benzene, and phenol, and polycyclic aromatic hydrocarbons. The Primary Site is currently being used as a recycling facility. Various materials are present all over the southern portion of the Primary Site. Items on the ground include large quantities of plastics, fiberglass, metal buttons, and wire, as well as rusting and buckled metal and plastic drums. The northern half of the Primary Site is not in use.

Current Site Status and Cleanup Actions to Date

  • In 1988, EPA stabilized the tar pits to prevent a major release into the North Fork of Mill Creek.
  • In 1989, the State of Tennessee authorized the relocation of the downstream Bon Aqua-Lyles Water District primary water intake.
  • From September 1993 through July 1999, EPA disposed of transformers, waste debris, waste sludges, tar-cubes, and visibly friable asbestos corrugated material; and excavated and recycled as fuel contaminated soil and wood tar.
  • From 1993-1995, the TDEC, under a CA with EPA, removed and disposed of 5,285 tons of contaminated soils and materials. It also sampled private wells around the site. No site related contaminants were detected in wells surrounding the site.
  • From September 1993 through July 1999, EPA also removed, aerated, and discharged water in the Storage Basin and Overflow Basin to Hollow Creek; removed a discrete layer of fluid-like tar material on the bottom of the Storage Basin; and removed and disposed of 2,172 tons of visible contaminated soil at the tar/soil interface of the Storage Basin, a small amount of material consisting of tar residues from the Overflow Basin, and 3,113 tons of contaminated material from the former on-site tar pits.
  • In November 2002, EPA collected two surface soil, four sediment, six surface water (spring), and eight potable well samples at request of local citizens, and no site related contaminants were detected in potable wells surrounding the site.
  • In December 2003, EPA began the RD investigation to determine where to excavate contaminated soil (PDF) (530 K, 2 pp). During this investigation, EPA discovered a previously unknown extensive area of Non Aqueous Phase Liquids (NAPL) in the shallow groundwater on the Primary Site.
  • As a result of these discoveries, and since it is more practical and less expensive to handle all excavation at one time, EPA has postponed further implementation of the cleanup plan until it can investigate and sample these newly identified areas. Once this is complete, EPA will determine if revisions or amendments need to be made to the cleanup plan.
  • September 2004, the ATSDR completed a Health Consultation of the Athletic Field concluding no health hazards.

Current Funding Status

  • EPA spent approximately $1.2 million on its 1988-89 Removal Action.
  • EPA has spent approximately $4 million on its 1993-1995 interim cleanup action.
  • EPA has spent approximately $2 million developing the Supplemental Remedial Investigation and Feasibility Study (RI/FS) and a Final Record of Decision (ROD).
  • The site is still in the RD phase, and did not require new construction funding in Fiscal Year 2004.

Key Accomplishments

  • From 1993-1995, the Tennessee Department of Environment and Conservation (TDEC), under a Cooperative Agreement (CA) with EPA, removed and disposed of 5,285 tons of contaminated soils and materials. It also sampled private wells around the site. No site related contaminants were detected in wells surrounding the site.
  • In December 2003, EPA discovered a previously unknown extensive area of groundwater contamination.
  • In September 2004, the Agency for Toxic Substances and Disease Registry (ATSDR) completed a Health Consultation of the Athletic Field concluding no health hazards.
  • In October 2004, Remedial Design (RD) investigation expanded to evaluate new discoveries.
