Both the Miami-Dade County Department of Health and the Department of Environmental Resources Management (DERM) require this regular, free-chlorine treatment on an annual basis. This routine procedure is regularly scheduled each year, as free chlorine is considered an effective method of cleansing water distribution systems.
County residents may experience some chlorine smell and/or taste in their water during this short-term changeover. This is normal as free chlorine has a slightly different taste and smell than combined chlorine. The temporary change does not cause adverse health effects and is a necessary part of WASD’s ongoing efforts to provide safe, potable drinking water to Miami-Dade County residents.
Residents who have any questions about the quality of Miami-Dade’s water during the annual chlorine purge, or at any time, may call a WASD laboratory at 305-520-4738 (for residents who live north of SW 8th Street); or 305-275-3170 (for residents who live south of SW 8th Street).
