Average monthly temperatures vary from 45 to 75 degrees F, with an annual average of 60 degrees F. Annual precipitation is 17.2 in, with January being the wettest month. Approximately 660 acres of the base are underlain by plumes having TCE concentrations above the drinking water standard. The known areal extent of soils contamination is about 370 acres. Demonstration facility used to demonstrate systems for characterization and remediating soils, sediment, and ground water contaminated with fuel hydrocarbons and waste oil, using either in situ or ex situ techniques. A 300x180x2 ft impoundment area within the facility has been constructed to assure all rainwater and test fluids are captured and monitored for contamination levels before discharge.
Facility is monitored to detect any contamination migration from the site.
In addition to the ex situ site, several isolated sites have been identified for in situ demonstrations of characterization and remedial technologies for contaminated soil, ground water, harbors, canals, and wetlands. A three dimensional monitoring network with long-term data retrieval is available for data comparison. Ground surface is relatively flat, and is underlain by approximately 300' of unconsolidated clay, silt, sand, and gravel of Holocene age that overlie clay, shale and sandstone deposits of Pleistocene and older ages. The geology, within 30' of the surface, consists of unconsolidated sands, silts, and clays with minor amounts of gravel and fill material. CBC experiences a moderately dry climate with mild, moist winters, and warm, dry summers.
