LAKE JACKSON, Texas – The road to drinkable water won’t be a short one in Lake Jackson after a brain-eating amoeba was found in the water system. The discovery initially led officials to issue a do-not-use order for the Brazosport Water Authority. That was later changed to a boil-water notice for the city of Lake Jackson. Officials said they believe BWA’s distribution system is clean and that the issue is limited to Lake Jackson, where 11 of 54 sites tested there showed low levels of disinfectant. Baker said monthly and quarterly testing records for Lake Jackson show nothing of concern leading up to the discovery of the amoeba.
