Answer

Adequate chlorination of swimming pools may prevent waterborne outbreaks. Adenovirus is relatively hardy and survives long periods on surfaces and in fresh water. Like norovirus and rotavirus, adenovirus is resistant to many common disinfectants, but killed by properly maintained disinfection of recreational aquatic venues. Residential and public pools should be maintained at a continuous free chlorine range within 1-3 ppm and pH 7.2-7.8, which close attention during heavy use periods. Residential and public hot tubs should be maintained at a free chlorine of 3-10 ppm and pH 7.2-7.8. Regularly updated recommendations and evidence-based Model Aquatic Health Code are found at  Healthy Water | CDC.
