IN-SITU REMEDIATION OF JET A IN SOIL AND GROUND-WATER BY HIGH-VACUUM,DUAL-PHASE EXTRACTION

This report summarizes the initial results of subsurface remediation a t Terminal 1, Kennedy International Airport, to remediate soil and gro und water contaminated with Jet A fuel. The project was driven and con strained by the construction schedule of a major new terminal at the f acility. The remediation system used a combination of ground water pum ping, air injection, and soil vapor extraction. In the first five mont hs of operation, the combined processes of dewatering, volatilization, and biogradation removed a total of 36,689 pounds of total volatile a nd semivolatile organic jet fuel hydrocarbons from subsurface soil and ground water. The results of this case study have shown that 62 perce nt of the removal resulted from biogradation, 27 percent of the remova l resulted from biodegradation, 27 percent occurred as a result of liq uid removal, and 11 percent resulted from the extraction of volatile o rganic compounds (VOCs).
