Background

The South 8th Street Landfill site consists of a 16-acre landfill that contains a 2.5-acre oily sludge pit in West Memphis, Arkansas. Waste disposal activities contaminated soil and groundwater with lead, polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs). Following cleanup, EPA took the site off the Superfund program’s National Priorities List (NPL) in 2004.

What Has Been Done to Clean Up the Site?

The site is being addressed through federal, state and potentially responsible party (PRP) actions.

EPA has conducted several five-year reviews of the site’s remedy. These reviews ensure that the remedies put in place protect public health and the environment, and function as intended by site decision documents. The most recent review concluded that response actions at the site are in accordance with the remedy selected by EPA and that the remedy continues to be protective of human health and the environment.

The landfill on the site collected waste material beginning around 1957. The Gurley Refining Company used the site between about 1960 and 1970 for the disposal of waste sludge from its re-refining process west of the St. Francis Levee. The sludge waste in the pit has physical and chemical properties similar to material typically identified at oil reclamation facilities.

Between 1981 and 1988, EPA completed soil boring investigations of the oily sludge pit and surrounding landfill areas. Sampling found PAHs, PCBs, benzene, toluene, ethylbenzene, xylene, pesticides and heavy metals at the site.The landfill on the site collected waste material beginning around 1957.

What Is the Current Site Status?

The site’s long-term remedy included the excavation, treatment and off-site disposal of contaminated sludge, soil and debris; a natural soil cover; installation of erosion control features; deed notifications; and groundwater monitoring. EPA later updated the remedy to include in-place stabilization and solidification of the oily sludge pit and monitored natural attenuation with institutional controls for groundwater. The in-place treatment of the oiliy sludge pit was finished in 2000. Groundwater monitoring has been completed.

Following cleanup, EPA took the site off the NPL in 2004.

Emergency Response and Removal

Initial actions included fencing the site and constructing a berm around the oily sludge pit to minimize human exposure to site contaminants.
