8 Texas cities were alerted to a brain-eating amoeba found in water supply - CNN

Disaster declaration issued in Lake Jackson

Lake Jackson has issued a disaster declaration and residents are still being urged to heed the Do Not Use Water Advisory until the Brazosport Water Authority has completed an adequate flush out of its water system, according to TCEQ.

The incident started on September 8, when the city was made aware of a 6-year-old boy who was hospitalized with the amoeba.

The results came back negative on September 14 for Naegleria fowleri, and the CDC was contacted for further water testing from the splash pad.

Representatives from the Texas Department of Health Services collected water and tested samples from the splash pad for the CDC, and on On September 25, three of the 11 water samples tested positive for Naegleria fowleri.

The CDC sent the test results to the TCEQ, and the Texas agency then required that the Brazosport Water Authority issue a Do Not Use water advisory for their customer base, the statement reads.
