Water and chlorine
Some brands of mineral water wash their bottles with chlorinated water, and chlorine is also added to many types of water to keep it sterile, to kill bacteria. Pineo water is naturally bacterially pure, and we do not wash our bottles with chlorine, keeping the taste pure. Natural mineral waters that are high in chlorine are not recommended at meals.
Chlorine in Pineo water: 1.9 mg/litre.
