b. The AMEDD personnel are responsible for monitoring water supplies to
ensure that they are potable at points of distribution (para 5-2d). However, it is virtually
impossible to monitor water quality to the point of consumption. Units frequently pick up
water in large tank trucks and further distribute it to subordinate units by filling their
water trailers. Water is then transferred from trailers to Lyster bags (figure 6-2) or 5-
gallon water cans for individual and small-unit use. During the process, water is subject
to further contamination through careless or improper handling and the use of
contaminated containers. It is thus the unit commander's responsibility to ensure that all
personnel are trained in unit and individual water purification procedures.
c. Isolated units, small patrols, and individuals may not always be able to obtain
water from established water points. In such cases, they must exercise resourcefulness
in exploiting the best possible water sources and follow established purification
procedures to ensure the potability of the water before using it for drinking or cooking.
