Short-Term Consumption: These standards (Table 1-6) apply to units operating for 7 consecutive days

or less when the commander determines that an operational condition exists which prevents troop access to

drinking water meeting long-term consumption standards. Preventive medicine personnel should advise

commanders on selection of water sources and the potential use of short-term consumption standards. The

commander must accept the risk of possible decline in troop performance, increased incidence of disease,

casualties from toxic substances, and reduced combat efficiency with each day the imposition remains in

effect.
