On the grand opening day of Great Wolf Lodge in Webster, Texas, a chemical incident hospitalized 16 employees and contractors after a contractor improperly mixed pool chemicals, specifically sodium hypochlorite with sulfuric acid, causing a dangerous reaction. The incident occurred in an isolated building, separate from the hotel and water park, and was declared a Hazmat situation by local fire officials. Emergency responders quickly transported the affected individuals to local hospitals and confirmed that no chemicals were detected in the main facilities. The Webster Fire Department managed the situation, ensuring the area was secured and that further operations at the resort would not be impacted. Great Wolf Lodge has stated they are working with environmental companies to safely clean the affected tanks. The incident raised concerns but did not delay the lodge's operations, as it received the all-clear from authorities shortly after.
