To Do: Migrate
NCPTT staff visited Fort Livingston, Grand Terre Island, on June 16, 2010 to evaluate the condition of the structure and the amount of oil contamination; to conduct field tests on cleaning methods; and to collect oil, water, and oil-contaminated sand samples for further testing in the laboratory. The amount of oil and area of contamination were documented in field notes and through associated photographs. The structure was severely damaged in a hurricane in 1915. The remaining portions of the structure are in relatively good condition, but are more vulnerable to storm-generated waves and erosion because the gulf- facing side of the fort was destroyed.
A wavebreak was constructed more recently (approximately 20 years ago) and provides some measure of protection from weather- related damage. The surfactants that were tested to clean oil from a small area performed satisfactorily. A poultice was also effective at removing surface soiling, though would be more effective at removing stains that penetrate the surface if left for a longer period. Further laboratory testing is planned and will be shared with the Louisiana Office of State Parks as the results are complied.
