The U.S. Military’s Drinking Water: From “Water Buffalo” to PFAS Contamination

Field Water Systems: From Lyster Bags to the Water Buffalo
The Army first used the canvas Lyster Bag—a 36-gallon calcium-hypochlorite system invented by Maj. William J. Lyster in 1910—to supply troops from World I through Vietnam. It was later superseded by the M149 “Water Buffalo,” a 400-gallon steel trailer whose interior linings peeled, calcium built up, and chlorine was added only to meet legal limits, yielding water that was safe but widely deemed undrinkable.
PFAS Contamination and Health Data
A 2022 DoD assessment found PFAS—PFOA and PFOS—above safe limits at 24 bases, affecting over 175,000 service members. Advocacy groups estimate more than 600,000 personnel and families may have been exposed. At Camp Lejeune, solvents reached concentrations up to 3,400 times current limits, linked to higher rates of kidney and liver cancer and ALS. The Pentagon’s PFAS cleanup budget, now near $39 billion, still trails the projected $50 billion cost and a possible 50-year remediation timeline.
Official Responses and Ongoing Criticism
The DoD publicly confirmed the PFAS findings and earmarked extra funds for testing and remediation. The CDC’s analysis of Camp Lejeune data prompted the Camp Lejeune Families Act, granting medical benefits to affected families. Critics contend the funding pace is insufficient, compensation does not cover long-term health monitoring, and the swift provision of bottled water in Iraq/Afghanistan starkly contrasts with the sluggish cleanup of legacy contamination.
Service Member Experiences
Veterans say heated water often tasted “thicker, almost slimy,” while chlorine faded after several days. Bottled water pallets left on sun-scorched tarmacs became near-boiling, yet still offered a psychological break from the Buffalo’s taste. Soldiers added MRE drink mixes or commercial powders to mask flavor, cherishing any cold bottle as a rare comfort.
Conflicting Findings and Information Gaps
Manuals claim chlorine makes water legally safe, yet PFAS testing shows contaminants above health limits. The exact number of PFAS-tainted installations remains uncertain, and comprehensive long-term health data for all exposed personnel are still being gathered.
Verbatim Quotes
- “The United States military can put a munition through a window from 30 miles away, but it has never once, in its illustrious history, managed to make water that doesn’t taste like it was filtered through a mop head.” — Sgt. Zoe Morris, U.S. Army National Guard
- “Zoe Morris) If you served in any way that involved going out to “the field,” you will know the Water Buffalo well.” — Sgt. Zoe Morris, U.S. Army National Guard
- “You’ve never drank real military drinking water unless you’ve had it from a plastic bladder.” — Sgt. Juanita Philip, U.S. Army
- “thicker, almost slimy.” — Spc. David Miller, U.S. Army Infantry
Future Actions
The Pentagon will broaden PFAS testing to additional sites, increase remediation funding, and expedite veterans’ claims. Legislative proposals seek a uniform federal PFAS cleanup standard for all military installations.
