RCAC: Once More into the Bleach: Handling & Application of Sodium Hypochlorite

Description: Chlorine is the most commonly used drinking water disinfectant in all regions of the world. Today, about 98 percent of U.S. water treatment systems use some type of chlorine disinfection process to help provide safe drinking water. By a huge margin, sodium hypochlorite is the disinfectant used by the vast majority of small (less than 10,000 population) water systems. Hypochlorite is also the most hazardous chemical used by most of these water systems. If improperly handled, sodium hypochlorite can create a hazardous and potentially fatal environment.
