Strategic Biofuels is building Louisiana Green Fuels (LGF), a carbon-negative waterfront facility in the Port of Columbia, Louisiana, that will produce low-carbon fuels and power. The Port of Columbia is highly supportive of LGF’s mission to produce sustainable aviation fuel and naphtha using forestry waste, mostly roundwood feedstock (logs and round sections of wood) from managed forests that is compliant with the federal renewable fuel standard.

One consequence of the damage from the Hurricane Katrina storm surge was that the allowable water levels in the repaired canals was reduced relative to pre-Katrina elevations to maximize the potential water storage within the canals during subsequent hurricane events and to minimize the adverse impacts of sustained high-water levels in the canals.

Sediment and Water Characterization and Site Remediation in Bayou Carlyss, Louisiana

A manufacturing client retained Geosyntec to support closure of the bayou sediments, groundwater, surface soils, and dredge spoils areas of interest at a former liquid waste disposal site. Waste materials were disposed of in open ponds at the site from the 1950s to 1971. In 1991 through 1995, liquid chlorinated hydrocarbons and impacted sludge were removed from the ponds, which were closed under Louisiana Department of Environmental Quality (LDEQ) oversight. In 1977, Olsen's Bayou, the predominant surface water feature at the site, was dredged by the United States Army Corps of Engineers (USACE).

Construction of an Innovative Permeable Reactive Barrier to Passively Treat TCE within a Storm Sewer System

The Michoud Assembly facility is an active plant operated by Lockheed Martin for NASA. The facility is engaged in the manufacture and assembly of the external tank for the space shuttle. In 1966, about 100 tons of TCE were released from a large tank in the Building 190 Tank Farm Area. Subsurface investigations revealed the presence of chlorinated ethenes, primarily TCE and its degradation products, in soil and groundwater samples. A groundwater extraction and treatment system was installed to address shallow groundwater contamination. However, the storm drainage system within the area has been found to be leaking and therefore acts as a groundwater "sink" in the main area of contamination. This leakage to the storm sewer system resulted in unacceptable concentrations of VOCs in the storm sewer water.
