Long-Term Consumption: These standards (Table 1-7) apply to all situations that continue for more
than 7 days and where potable water is produced by water purification units. These standards were
developed by the United States Environmental Protection Agency (EPA) for municipal drinking water
systems. These standards can also be adopted as a goal to provide the highest quality water possible. In
using these standards to evaluate potential health hazards, it is important for you to consider the target
population (field force), duration of exposure, and other factors used to apply the standards to a given
situation. Other factors may involve an NBC situation.
