These manuals were developed by CDC during the 1950s, 1960s, 1970s and early 1980s. Much of the information in the manuals may still be helpful to aquatics staff, designers, and public health professionals. However, CDC’s Healthy Swimming and Model Aquatic Health Code websites have the most current information on water quality, disinfection, and operation for aquatic venues, thus superseding information found in these earlier manuals.
