Pool Disinfection: Stories from the Field
From chemical and microbiological contamination resulting from both environmental and anthropogenic sources, several challenges are facing the pool operator. Microbial contamination in pools can range from nuisance, as in algae, to serious health risks in the form of pathogenic bacteria and parasites. Best practices to achieve clean and sanitary water have varied over the decades as a function of time, geographical location, and type of venue. These changes in practices have included assay methods, minimum disinfectant levels, changes in filtration type, turnover rates, and pathogens of concern. This presentation will consider examples from the scientific literature with an emphasis on practical learnings from real pools. Decades of interest from scientists and public health officials have provided us with valuable insights and case studies about when disinfection failures occur. This session was presented at the 2020 World Aquatic Health Conference by Jeffery Gaulding, Ph.D. and John Weber.
- Examine proper pool disinfection.
- Review sanitation field studies.
