Beyond what sits dissolved in the liquid, the container holding your beverage warrants a critical look. Over the past several years, independent environmental testing programs uncovered variable concentrations of per- and polyfluoroalkyl substances (PFAS) in carbonated consumer waters. PFAS chemicals, frequently dubbed "forever chemicals," are synthetic compounds linked in clinical literature to low birth weight, pregnancy-induced hypertension, and endocrine disruption.

The contamination typically traces back to untreated source water rather than the carbonation process itself. Most municipal-sourced seltzers utilize reverse osmosis filtration that effectively filters long-chain and short-chain PFAS down to non-detectable levels.

Similarly, fears regarding bisphenol A (BPA) in aluminum can liners have driven industry transformations. Nearly all major beverage canning lines utilize BPA-Non-Intent (BPA-NI) epoxy coatings or polyester polymer barriers. While entirely avoiding plastic and coated aluminum exposure remains difficult in modern commerce, reaching for brands that publish third-party water purity testing, or opting for glass-bottled sparkling water, remains the gold standard for precautionary prenatal care.
