As a precaution, the National Centers for Disease Control and Prevention (NCDC) urges residents to pay attention to the taste, smell and color of their tap water. "If you notice a change in the normal taste, smell or color of the water, do not use it for drinking or cooking until the changes are eliminated and the official announcement is made. In the meantime, prefer boiled or bottled water. Inform the "Veolia Water" company about the change," says the HCCA.
