Choosing the healthiest bottled water in 2018 required looking beyond the glossy marketing and toward the specifics of sourcing, purification, and mineral content. With the market flooded with options ranging from artesian spring water to electrolyte-enhanced varieties, consumers needed clear guidance to find water that genuinely supported their health. This analysis focuses on the key metrics that define quality, providing a reliable reference for making informed hydration choices.
Understanding Water Quality Standards
The baseline for any healthy bottled water is compliance with strict safety regulations, yet not all standards are created equal. While the FDA regulates bottled water as a food product, setting forth guidelines for contaminants and bottling practices, some brands voluntarily adhere to the even more rigorous standards of the International Bottled Water Association (IBWA). In 2018, the healthiest options distinguished themselves by exceeding basic compliance, offering transparency regarding their source and purification methods. Consumers were advised to look for specific certifications and third-party testing results to ensure the water was free from industrial pollutants, heavy metals, and microbial contaminants.
The Role of Source Water
The origin of the water plays a critical role in its final quality and taste profile. Spring water, sourced from underground formations that naturally flow to the surface, was often favored for its clean, crisp flavor profile. Mountain spring water, in particular, filtered through layers of rock and sand, gained popularity for its perceived purity and natural electrolytic balance. Conversely, purified water, which undergoes processes like reverse osmosis or distillation, starts with a blank slate. While effective at removing impurities, this method also strips the water of naturally occurring minerals, leading many health-conscious brands to reintroduce them afterward to ensure the water remains beneficial to the body.
Purification Methods Compared
Understanding the technology behind purification is essential when evaluating the healthiest bottled water in 2018. Reverse osmosis (RO) emerged as the gold standard for filtration, capable of removing up to 99% of dissolved solids, including heavy metals and pharmaceutical residues. However, because RO is so aggressive, it removes healthy minerals like calcium and magnesium. To counteract this, leading brands employed remineralization filters, adding back essential electrolytes like potassium and sodium. Distillation, while effective at killing bacteria, was less common for premium health brands due to its inability to remove volatile chemicals without additional carbon filtration.
Key Contaminants to Avoid
When assessing the healthiest options, the presence of specific contaminants was a primary concern. Microplastics became a significant talking point in 2018, with independent studies detecting them in major brands, raising questions about long-term health implications. Consumers were encouraged to seek out brands that utilized advanced filtration capable of removing submicron particles. Additionally, the presence of arsenic, found naturally in certain groundwater sources, and sodium, which can affect blood pressure, were critical metrics. The healthiest bottled water maintained extremely low parts-per-billion (ppb) levels for these elements, ensuring the water served as a pure source of hydration rather than a vector for chemical exposure.
Essential Minerals and Electrolytes
Beyond the absence of toxins, the healthiest bottled water in 2018 was characterized by a beneficial mineral profile. Natural mineral water, defined by the FDA as containing at least 250 parts per million (ppm) of total dissolved solids (TDS), provided magnesium, calcium, and potassium essential for bodily functions. Even purified waters were often fortified to ensure they contributed to daily mineral intake rather than leaching minerals from the body during hydration. A balanced Total Dissolved Solids (TDS) reading, generally between 50 and 200 ppm, indicated a water that was clean yet retained the electrolytes necessary for optimal cellular function.
