Potable water on board can contain both microbiological and chemical contaminants. Causes include high temperatures, poor hygiene conditions and disinfection with (excessive) amounts of biocides, such as active chlorine. The standards and guidelines from the WHO, the EU and the MLC state what potable water on board must comply with, not only in terms of being able to drink it safely, but also in terms of preventing Legionnaires’ disease.
