The U.S. Navy identified a specific biodegradable, or "green," laundry detergent as a contributing factor to sanitation system issues aboard the aircraft carrier USS George Washington. The detergent was part of environmental initiatives to reduce the ship's impact.
According to Navy investigations, the detergent created excessive suds that interfered with the ship's sewage and wastewater systems, known as the Collection, Holding, and Transfer (CHT) system. This led to maintenance challenges and sanitation concerns for the crew.
The USS George Washington, a Nimitz-class carrier valued at billions, underwent a complex mid-life refueling and overhaul. The detergent issue was one of several logistical and habitability problems reported during this period, which impacted crew morale and operations.
The Navy has since taken corrective actions, including changing detergent specifications and improving system maintenance procedures to prevent recurrence. The service emphasizes balancing environmental goals with operational reliability and sailor welfare.
