Ideally, the pool water pump and pool chemical feeders should be operationally linked to prevent sudden influxes of excess chemical following a lull in pumping. Accidents like the one at Camp Letts could be avoided in the future if pools are designed and operated according to specifications in the new Model Aquatic Health Code. The Centers for Disease Control and Prevention is drafting the code as expert guidance to states and localities on the design, construction, operation and maintenance of public swimming pools. CDC expects to issue a completed version of it this summer after which it will be available to states and localities to adopt into law. It's a giant step in the right direction toward greater public safety in aquatic venues.
