So again, as with cancers, with non-cancerous health effects, nothing specific can be pointed on. Despite this, the United States EPA has estimated based on animal experiments that excess chlorine in drinking water that enters the body through oral route can be associated with cellular necrosis. This may result in some people suffering from dryness or eczema. So we can potentially build an environmental health risk assessment for possible eczema for people consuming drinking water containing chlorine as disinfectant.
