Above 100 psid 8. Above 1500 ppm 3. The basic procedures for disinfecting water are given below. These procedures may be modified in the field environment by the unit medical department to adapt to the local conditions or circumstances. Such factors as the quality of the water source, diseases endemic to the area of operation, diseases experienced within the unit, and the integrity of the unit water system must be considered.
Chlorination is the most common method of disinfecting potable water.
This is the preferred agent because it comes in granular form, has a long shelf-life and is readily available from the Navy stock system. This is the most common form used by municipal water treatment plants. However, chlorine gas is not normally considered appropriate for field use. Stir the mixture thoroughly. Note that not all granules will dissolve Allow undissolved granules to settle to the bottom of the container.
