Distillation systems covered by this Standard are systems designed to be used to reduce specific chemical contaminants as specified herein from public or private drinking water supplies. Systems designed to reduce microbiological contaminants from public or private water supplies are also covered under this Standard. Systems covered by this Standard are not intended for the treatment of water that is visually contaminated (turbid) or has an obvious contamination source, such as raw sewage, nor are systems intended to convert wastewater to microbiologically potable water. This Standard establishes minimum requirements for point-of-use and point-of-entry drinking water distillation systems and materials and components used in these systems.
