A Brief Overview
The Multistate Trust Property — outlined in green in the map inset at lower right — includes most of the Kerr-McGee Chemical Corp–Navassa Superfund Site.
The Multistate Trust owns approximately 154 acres located on the east side of Navassa Road. The Multistate Trust Property (the Property) is bounded on the north by Quality Drive, on the east by the Eastern Marsh on the Brunswick River, and on the south by the Southern Marsh on Sturgeon Creek. The Property includes most of the Superfund site and is part of the approximately 246-acre property that Kerr-McGee formerly owned.
The site was used for creosote-based wood treating from 1936 to 1974. By 1980, then-owner Kerr-McGee Chemical Corporation dismantled the wood-treatment buildings and facilities.
The surface soil, subsurface soil, marsh sediment, and groundwater are contaminated by creosote-related chemicals. In 2010, EPA added the site to the National Priorities List of federal Superfund sites. Site contamination does not currently threaten people living or working near the site in this Environmental Justice community.
In 2005, the site was conveyed to Tronox, a Kerr-McGee spinoff that filed for bankruptcy protection in 2009. In 2011, as part of the global Tronox bankruptcy settlement, the Multistate Trust took ownership of the property and assumed responsibility for investigating, cleaning up, and facilitating reuse of the Superfund site.
