Miami-Dade has notified us that their water treatment procedures will change for the next two weeks. The following is a summary of their notification.
November 9th thru November 22nd, the Miami-Dade Water and Sewer Department (WASD) will temporarily change its method of chlorination at each of its regional water treatment facilities. The free chlorine treatment will be used to provide a stronger disinfection and bleaching process than the combined chlorine treatment which is normally used. During this period a consumer may experience unusual chlorine taste or odor in the tap water. These temporary conditions will not cause adverse health effects. This annual treatment will ensure adequate disinfection levels in the water.
The free chlorine residual produces trihalomethanes (TTHM’s). The combined residual chlorine, as normally applied, greatly reduces the formation of TTHM’s. Consuming water with elevated TTHM levels during this two-week treatment period will not result in any adverse health effects; however, consumers with tropical fish should contact their aquarium supplier or pet shop for specific guidance regarding water changes during this period.
Public Notices announcing the “Free Chlorine Treatment Period” was published in local newspapers. All hospitals, kidney dialysis centers and pet shops were notified individually by certified mail.
