AFFF Disposal and Treatment
9.4
The usual method of disposing AFFF solution is through regulated
flow to the wastewater treatment plant. Flow rate is dependent
upon the size and capacity of the treatment plant, and must not
exceed 1700 parts per million at the plant. Other methods such
as solar evaporation, on-site treatment and transport to an off-
site treatment facility may be utilized based on local
conditions. Regardless of what type of disposal arrangement is
provided, it is essential that foam solution from system testing
and inadvertent discharges be disposed of in an environmentally
responsible manner.
