Association Between Swimming Pool Operator Certification and Reduced Pool Chemistry Violations—Nebraska, 2005–2006

0
Previous studies have recommended mandatory education for all public pool operators, but substantiating data are limited. This study evaluates associations between pool operator certification and chemistry violations by using 2005–2006 Nebraska routine pool inspection reports. Training and certification for nonmunicipal pool operators are only required in two Nebraska counties. Free chlorine violations for nonmunicipal pool inspections were compared in counties with and without certified operator requirements. To control for water supply pH, inspections from nonmunicipal pools with shared-source water in two counties (one requiring certification) were compared for concurrent pH and free chlorine violations. Compared with locations that require certified operators, free chlorine violations and concurrent pH and free chlorine violations were twice as likely in locations without certification. As a result, pools without required operator certification might pose greater health risks. These results demonstrate the benefit of requiring pool operator certification to help prevent recreational water illnesses.
