No, it was too long in contact with plastic. It is full of that shit 🙃

Sealed = no microbial growth, so it won't acutely make you sick. Real concerns: (1) PET plastic leaches small amounts of antimony and phthalates over time, accelerated by heat — and a garage gets hot in summer. The migration is well below acute-toxicity thresholds but the taste turns plasticky. (2...

Most cased bottled water is in PET plastic bottles which can break down rather quickly under UV light (sunlight) but is much more stable in the shade. Breakdown can release soluble plastic precursors and very small amounts of antimony (a metal used as a polymerization catalyst that is toxic in high...
