Bottled water for formula ?

Destiny

I know this is a stupid question, but can i use poland spring bottles water for baby formula ? I asked the doctor when i left the nicu if i could use water from the water dispenser that i have and she said yes, that i could even use tap water if i wanted. But now i read on google that mineral water is a no, and poland spring is a mineral water. So can i use it or is google making me crazy ?
