Aquafina to say it comes from same source as tap water

24. There are several reasons bottled water tastes better

First, nearly all of the major bottled water vendors do pH and mineral balancing of their water, and the balances are optimized to the human palate. With tap water, you get what the local ground or rivers give you. In some parts of the U.S. (San Francisco) the tap water is awesome. In others (Orlando) it's barely palatable.

Second, you have the chemicals. Municipal tapwater sources add everything from chlorine to flouride to tapwater, and that impacts the taste. Virtually all bottled water companies filter these out.

Third, you have the TDS issue. Total dissolved solids are basically all of the various crap that gets into water as it flows through the aquifier, gets pumped and stored, and then makes it through the cities pipes into your house. TDS in natural water sources can be up to 6000mg/liter. Federal law limits TDS to 500mg/liter, and most cities are going to be somewhere between 150mg/liter and 250mg/liter. Your average filtered bottled water is going to have under 100mg/liter, and some of the top brands like Aquafina are down in the 20mg/liter range. Because TDS is basically random crap floating around in your water, it has a huge impact on taste.

My local tap water is pretty gross, but I've got a Pelican whole house reverse osmosis system that makes my tapwater just about as clean as bottled water. I've got 65mg/liter at the kitchen tap, and 210mg/liter at the unfiltered outside hose bib.
