Redwing Carriers, Inc. operated a trucking company in Saraland, Alabama from 1961 to 1971, leaving behind contaminated soil, groundwater, and sediment. The property was later redeveloped into an apartment complex in 1973. EPA added the site to the Superfund National Priorities List (NPL) in February 1990 and oversaw cleanup through a single operable unit, OU01, which addressed all contamination on the property.
EPA identified 34 contaminants of concern across soil, groundwater, and sediment. These include pesticides such as aldrin, dieldrin, and DDT, solvents such as acetone, carbon tetrachloride, and chloroform, heavy metals such as arsenic, chromium, lead, nickel, beryllium, and vanadium, and polycyclic aromatic hydrocarbons (PAHs) such as benzo[a]pyrene and chrysene.
Cleanup was extensive and took place over several decades. EPA temporarily relocated 57 residents in 1996 and permanently relocated them in 1997. Workers removed 20,724 tons of sludge, contaminated soil, and debris, along with 25,114 cubic yards of soil. Buildings and concrete structures were demolished in 2004. The original remedy selected in 1992 included groundwater extraction and treatment, dredging, and population relocation. A 2000 amendment revised the remedy to focus on excavation, demolition, offsite disposal, and monitoring. Construction of the remedial action was completed by September 2009.
A five-year review completed in September 2014 confirmed that all cleanup goals had been met. Surface soil, subsurface soil, sediment, and groundwater all met established performance standards. Human exposure is under control, and groundwater migration is stabilized with no unacceptable discharge to surface water. EPA deleted the site from the NPL in September 2015. No further sampling, monitoring, or five-year reviews are planned.
