A back-log at a lab in Austin meant test results on a pair of College Station pools did not come back Wednesday as expected.
Officials now hope their pools will get a clean bill of health Thursday. Adamson Lagoon's baby pool and Thomas Park's main pool each tested positive for a microorganism that causes intestinal problems.
The city closed down both facilities to deep clean the pools.
Four reports of intestinal issues were reported to the Brazos County Health Department, prompting the testing of all College Station pools.
All of Adamson Lagoon was shut down as a precaution despite only the baby pool testing positive for cryptosporidium. Officials said the proximity of the pools was the reason for shutting both down.
Cryptosporidium can survive even in proper levels of chlorine. It is normally transmitted through feces.
