It is reported that soil and groundwater around the spot where Flight 93 crashed show no signs of jet fuel contamination. About a week after 9/11, the Pennsylvania Department of Environmental Protection (DEP) started taking soil samples from the 50-foot hole dug around the crash crater, to check for contamination by the plane’s fuel and other hazardous materials. Three test wells have also been sunk to monitor groundwater. [Pittsburgh Post-Gazette, 9/17/2001; WTAE-TV, 10/2/2001; Pittsburgh Post-Gazette, 10/3/2001] According to the National Transportation Safety Board, Flight 93 had about 37,500 lb of fuel remaining when it crashed. [National Transportation Safety Board, 2/13/2002, pp. 8 pdf file] Some of the first people who arrived at the crash site reported that there was an “incredibly strong” and “overpowering” smell of jet fuel in the air. [Longman, 2002, pp. 213; Kashurba, 2002, pp. 32, 40, 43 and 64] Yet, so far, no contamination has been found in either the soil or the groundwater. Betsy Mallison, a spokeswoman for the DEP, says that whether it burned away or evaporated, much of the jet fuel spilled at the site seems to have dissipated. [WTAE-TV, 10/2/2001; Pittsburgh Post-Gazette, 10/3/2001] DEP Secretary David Hess says most of the hazardous fluids must have been consumed by the crash’s fire. [Pittsburgh Post-Gazette, 9/17/2001] Yet some of the first people who arrived at the site say they only saw a very small fire, if any at all, at the crash crater. [Longman, 2002, pp. 213; McCall, 2002, pp. 30-31]
