HOUSTON – The family of a Lake Jackson boy killed by a brain-eating amoeba in the water supply has filed a lawsuit. The city of Lake Jackson and the Brazosport Water Authority are being sued for more than $1M. Langley said a deadly brain-eating amoeba was able to grow in the city’s water supply because tests discovered there wasn’t enough chlorine. “If the water supply was tested and tested frequently this could have been detected and could have been prevented,” he added. The Center for Disease Control was also called in to test the water supply.
