NOTE:
Reverse osmosis units take out most biological, chemical, and nuclear
agents, but need two chemical cartridges, with only one being used at a time.
b. Removal of Biological Agents. When the presence of resistant biological
agents is reported by authorized detection agencies and an alternate uncontaminated
source is not available, the prescribed treatment in connection with continuous flow
equipment is the super chlorination and dechlorination procedure out Iined in a(3)
above. A low pH, by acidification if necessary, is desirable.
c. Removal of Chemical Agents. When contamination by chemical agents has
been determined to be present in concentrations greater than the allowable
concentrations shown in Table 6-1, the water must be treated before use by one of the
following methods of decontamination:

chemical agents.
