Superfund Site: POPILE, INC., EL DORADO, AR
Superfund Site Profile
In 2003, EPA set up a monitoring program to make sure no contaminants are leaving the site boundary (defined by the railroad tracks). The flow direction for the shallow ground water to be monitored is toward north east i.e. from the site plume toward Bayou de Loutre. The monitoring plan was handled by Corps of Engineers (COE), New Orleans District. COE contracted with Materials Management Group (MMG) of New Orleans to start sampling. MMG collected samples in January 2004 had them analyzed by February 2004. Preliminary results did not conclusively show any breakthrough of the plume beyond the site boundary.
The 41-acre Popile, Inc. site is located in El Dorado, Arkansas. A wood-treating facility operated on site from 1947 to 1982. Waste disposal operations contaminated soil, surface water, groundwater and sediment with hazardous chemicals. Site drainage enters Bayou de Loutre. Following cleanup, operation and maintenance activities are ongoing.

TOPICS IN FOCUS
The objective of this site cleanup is to protect human health and the environment by controlling the migration of shallow groundwater contaminants to reduce and/or eliminate the potential of contaminating deeper aquifers, and if possible restore the shallow groundwater to a potential future beneficial use. The plan was to bio-remediate contaminated soils so that they do not leach contaminants into the groundwater and to bio-remediate groundwater in place. USEPA and the U.S. Army Corps of Engineers (USACE) conducted studies to determine the how successful soil and groundwater bioremediation can be. EPA has implemented the remedial action through USACE Total Environmental Restoration Contract (TERC) delivery orders.
