On November 20, 2021, a total of 14,000 gallons of a jet fuel/water mixture leaked from a fire suppression drain and penetrated the Red Hill potable water well, sickening, and displacing military service members and their families from Red Hill and Aliamanu Military Reservation (AMR) housing. Weston and team were contracted to perform time-critical treatment of the water system to remove petroleum and petroleum-related contaminants and ensure safe drinking water for residents, schools, and businesses across Red Hill and AMR housing areas. We mobilized to the site within 24 hours of award to support urgent restoration needs and implemented additional risk communication tactics to ensure safe/secure working conditions for field personnel as well as public safety. Our team installed a new double-entry gate in the existing fence line around the treatment system equipment area at AMR. At Red Hill, we repaired the existing outer fence line and tightened up the barb wire as well as installed 120 ft of new, temporary fencing around the Red Hill treatment system to prevent neighborhood children from accessing chemicals. Our treatment included construction and operational phases of the commissioning process for two 750 gallons per minute Granular Activated Carbon (GAC) systems ensuring clean drinking water for thousands of military families.
