DISPOSAL OF CHLORINATED WATER
Chlorine is widely used as a disinfectant
by water utilities. Chlorinated waters from potable water systems are
released to the environment through activities such as water main
flushing, disinfection of new mains, distribution system maintenance,
water main breaks, filter backwash and other utility operations.
Although chlorine protects humans from pathogens in water, it is highly
toxic to aquatic species in the receiving streams. In particular,
chlorine may be toxic to many species protected under the Endangered
Species Act, even at very low concentrations. |
