Mississippi has lifted a “boil water” advisory for Jackson, 40 days after the state’s Department of Health reported the city’s water supply was unsafe to drink. The problem was compounded in August, when torrential rains caused the Pearl River to overtop its banks, flooding Jackson’s main water treatment plant. Republican Governor Tate Reeves said Thursday tap water in Mississippi’s capital city is now safe to drink, though he admitted the system is “still imperfect.” The head of Mississippi’s chapter of the American Academy of Pediatrics warns Jackson-area caregivers preparing baby formula should continue to use bottled water because infants remain at risk of heavy metals or other toxins in the water supply.
