Introduction to Popile Inc., Arkansas Superfund Site

Site Description

Location:

41-acre site in Union County, Arkansas, about ¾ mile south of El Dorado City Limits. The property is bordered by South West Avenue on the west, Ouachita Railroad (East Camden & Highland Railroad) on the east, and Bayou de Loutre on the north.

Setting:

No drinking water wells located within ½ mile of the site. Residential, industrial, and commercial properties surround the site. Surface drainage is to Bayou de Loutre.

Water Use:

Shallow groundwater (20 feet deep) within the county is used primarily for livestock and irrigation. Deep aquifer (500 to 600 feet deep) wells more than 3 miles from the site, provide drinking water to more than 26,000 residents. These wells draw from a much deeper ground water zone than the shallow zone.

Current Site Strategy

The current site strategy is to protect human health and the environment by controlling the migration of contaminants in shallow groundwater to reduce and/or eliminate the potential for contaminating deeper aquifers, or migrating to the Bayou.

Health Considerations

  • Direct contact with soils.
  • Ingestion of ground or surface water.

Record of Decision

The Record of Decision (ROD) was signed on February 20, 1993. ROD Contaminants of Concern (COCs) are:

  • Pentachlorophenol (PCP).
  • Polynuclear Aromatic Hydrocarbons (PAHs) including: benzo(a)pyrene, dibenz(a,h)anthracene, benzo(a)anthracene, benzo(b)fluoranthene, benzo(k)fluoranthene, chrysene, and indeno(1,2,3-cd)pyrene.
Main features of the ROD are:
  • "In situ" (i.e., in-place) treatment of contaminated groundwater and extraction of free products.
  • On site biological treatment of contaminated soils and sludge by landfarm.
