A soil sample from the drilling core collected roughly 150 feet below ground surface at the former Reese Air Force Base near Lubbock, Texas, June 29, 2020. The Air Force Civil Engineer Center is moving forward with environmental remediation and will install twenty-five monitoring wells in a 12 square mile, down gradient area from the former base, to further determine human and ecological health risks, source areas, and migration patterns of Per-and polyfluoroalkyl substances (PFAS) contamination there.
