Volvic water originates as rainfall on dormant volcanoes in France, where it spends years filtering through layers of rocks and minerals before being bottled at the Clairvic Spring. This process gives Volvic water its unique blend of minerals including calcium, magnesium, potassium, and sulfates. The water is never even exposed to daylight until it is bottled. Volvic carefully monitors and protects the water source, and their quality laboratory tests water samples every day to ensure the mineral content stays consistent. Their bottles are BPA-free and made of recyclable PET plastic, and they only bottle a small fraction of the water that flows through the source to ensure sustainability.
