| Abstract |
The Brown Wood Preserving site is located west of the City of Live Oak, Suwanee County, Florida. The site contains a former wood preserving plant facility, which pressure treated timber products with creosote and some pentachlorophenol (PCP) for thirty years between 1948 and 1978. Sludge and contaminated soils have been identified in the immediate vicinity of the plant site and an upgradient lagoon. This three-acre lagoon drains approximately 74 acres and contains water provided above approximately 3,000 cu yd of creosote sludge and contaminated soil. In addition, small amounts of solidified creosote and PCP are contained in onsite storage tanks and retorts. The primary contaminants of concern affecting the soil, sediments, sludge, and waste water are creosote constituents including PAHs. The selected remedial action for the site includes: removal and treatment, if necessary, of lagoon water; excavation, treatment, and offsite disposal of approximately 1,500 tons of the most severely contaminated soil and sludge; onsite biodegradation of approximately 10,000 tons of the remaining soils in a 14-acre treatment area constructed with a liner and an internal drainage and spray irrigation system; covering of the treatment area with clean fill after bioremediation; and ground water monitoring. |
