The Texas Commission on Environmental Quality has issued a boil water notice for the City of Corsicana. Water samples collected recently showed the presence of E coli bacteria and fecal matter, meaning the water supply could have been contaminated with human or animal waste. City water customers have been notified to boil their water prior to consumption. Water Department officials will notify customers when the order is rescinded and the water is safe for consumption. Residents with questions regarding the notice are asked to contact the Corsicana Police Department.
