The bubbles in tap water are usually trapped air. The water travels through underground pipes where it is relatively cold and under pressure. When it comes out of the tap and into (for example) a glass it is no longer pressurised. It quickly begins to warm and the tiny bubbles of trapped air rapidly expand to a size where they can readily be seen.
