The Gulf Coast Water Authority (GCWA) will temporarily change its water disinfection process from chloramine (chlorine and ammonia) to free chlorine (chlorine only) April 16-30. All Galveston County municipalities, except League City, Friendswood and Bolivar, will be included.
This routine maintenance allows GCWA and the municipalities that it serves the opportunity to clean their water systems of harmless bacteria that can occur during warm weather.
Municipalities also will flush their systems by opening fire hydrants during this period. Flushing and the temporary switch to free chlorine help to maintain water quality during the hottest months of the year.
This process will not cause adverse health effects, though users may notice some water discoloration or cloudiness. Both of these conditions are harmless and temporary and should be remedied by fire hydrant flushing.
Owners of fish and reptiles should follow standard water treatments using products that remove both chlorine and chloramine from the water.
Dialysis centers will continue to treat the water to remove all chemical disinfectants, including chlorine and chloramine, before the water is used for dialysis. Home dialysis users should consult their machine manufacturers for instructions on how to properly treat their water before use.
Water users can contact their local municipality for questions about the water system disinfection period. GCWA provides water for industry, agriculture, and municipalities in Brazoria, Fort Bend and Galveston County. Read more at http://gulfcoastwaterauthority.com.
