HALAWA, Hawaii (April 10, 2024) Navy Closure Talk Force-Red Hill (NCTF-RH) contractors drain aqueous film-forming foam (AFFF) concentrate from a pipe inside the Red Hill Bulk Fuel Storage Facility (RHBFSF) in Halawa, Hawaii, April 10, 2024. Over 1,000 gallons of AFFF concentrate were safely drained from the AFFF system once the operation was completed, and will soon be removed from the facility, thus removing a major threat to the aquifer.
