Just curious.

The risk of plastic contamination is low unless you leave the bottles out in the sun for weeks. The risk from aluminum cans is considerably higher. Most bottled water IS tap water, sometimes purified a little. The legal requirements for purity of tap water are stricter than those for bottled water. Chlorine and fluorine are toxic, but they are legal, and are intentionally added. If you have a good, clean source, it's best to just get it out of the ground and not treat it. The source (rain/snow) is distilled, and nearly all contaminants that might enter the water system are effectively filtered out by sand in the underground strata.

There should not be toxic metals in tap water.
If the tap water is in a city, the city is responsible for good water. Does your house have old lead pipes? Most likely not.
If you are in the country with your own well have it tested. If there is a problem, get it fixed.
Use a filter on your faucet.
Plastic bottles have been used for a long time. Our soda comes in plastic as does milk, juice and other drinks.
There is not a leaking of elements from the plastic unless it is subjected to heat.

Both are very low risks. Both would be lower than the risk of being struck by lightning. Metal contamination from well water would be greater than either tap water or plastic.

The worst thing you can do is worry too much about it.
