Marco Island Utilities (MIU) will be temporarily changing the disinfection process for the potable (drinking) water supply. From September 1 through September 30, 2011, MIU will disinfect the water with free chlorine rather than combined chlorine/ammonia (chloramines). This conversion to chlorine (a stronger disinfectant) from chloramines allows MIU to perform an annual water distribution system purge as recommended by the Department of Environmental Protection for water utilities using chloramines as their primary disinfectant. The process will start at 9:00 AM on September 1, 2011.
This temporary change in disinfectant does not cause adverse health effects. However, during this period customers may experience a change in the taste, odor and color of the water due to the change in treatment.
Customers on Kidney Dialysis who use a proportioning machine to prepare dialysis at home are advised to contact their physician or equipment supplier to obtain the appropriate steps to accommodate the change in water disinfection and to install the proper filtering devices, if needed.
Customers who have fish tank or aquatic species are advised to contact the local pet store to ensure proper pretreatment of the water before adding or changing the water in the tank to avoid any problems associated with chlorine.
MIU will be performing a flush of the system in conjunction with this change in water treatment. Water customers should be aware that they might experience short-term changes to their water quality during flushing, including cloudy or discolored water. While this water is safe to drink, it may stain clothes that are in the laundry. Customers are advised to flush any cloudy or discolored water that may enter their plumbing by running a faucet for several minutes.
Customers are asked to call Ron Weis at the Marco Island Reverse Osmosis Plant @ 239-642-5405 or cell number 239-825-9004 with any questions concerning this change in disinfectants.
