From testing of various brands of water, the tap water is the same water you buy in a bottle at extravagant prices. Bottled water is the same as the source of the water with no improved purity. The best thing water departments could do to improve water quality is to stop putting in the chemicals of chlorine and fluoride. Bottled water also has these same chemicals and other minerals of their sources.

As for water quality of any area in the country, the use of federal guidelines are misleading and not in the best interest of the consumers. If they labeled bottled water they would use the same guidelines that the federal government as written. These guidelines are not law, they are only recommendations to allow for existing and man made contamination. Therefore such a law to label is meaningless and unenforceable.

Buying and spending money on bottled water is purely consumers uneducated spending. Watering animals out in the grazing fields has more restrictions and laws than there are for human consumption, even in tap and bottled water. It's easy to research this through local water supplies and the federal websites.
