Understanding the Basics: FDA Regulation and Great Value Water
All bottled water sold in the United States, including Great Value, is regulated by the U.S. Food and Drug Administration (FDA) as a packaged food item. This regulatory oversight ensures that products are safe for consumption, processed, and labeled correctly. The FDA has established standards of quality for bottled water, with many aligning closely with the Environmental Protection Agency's (EPA) standards for public tap water. For Great Value, which is Walmart's store brand, this means its suppliers must meet and exceed these federal and state regulations. Walmart corporate and their suppliers test the water regularly to ensure quality standards are met, with reports often available on their website.
The Purification Process of Great Value Purified Water
Great Value's purified drinking water undergoes a rigorous purification process designed to remove contaminants. The exact steps can vary slightly by bottling facility, but generally include:
- Filtration: Initial steps typically use activated carbon filters to remove chlorine and other organic impurities that can affect taste and odor.
- Reverse Osmosis: This key process forces water through a semipermeable membrane, effectively filtering out most total dissolved solids (TDS), including inorganic contaminants and heavy metals.
- Ozonation: As a final disinfectant, ozone gas is used to sanitize the water and bottles. Ozone is highly effective and dissipates quickly, leaving no taste or residual chemicals.
- Remineralization: For the purified drinking water variety, minerals are often added back after reverse osmosis to create a balanced flavor profile. Some customers have noted changes in taste due to shifts in this process or sourcing.
Potential Concerns: Microplastics and Plastic Packaging
A valid concern with any bottled water, including Great Value, revolves around the plastic packaging and potential for microplastics. Research shows that plastic bottles can release tiny plastic particles into the water, particularly when exposed to heat or sunlight.
- PET #1 Plastic: Great Value bottles are typically made from Polyethylene Terephthalate (PET), a plastic that does not contain BPA. While BPA is not a concern, the possibility of microplastics remains.
- Health Implications: The long-term health effects of microplastic ingestion are still under scientific investigation. While research is ongoing, many opt for reusable glass or stainless steel bottles to minimize exposure.
Great Value vs. Other Water Brands
To better understand how safe is Great Value drinking water, it helps to compare it to other common brands. The table below highlights key differences.
| Feature | Great Value Purified | Name-Brand Purified (e.g., Aquafina) | Name-Brand Spring (e.g., Poland Spring) |
|---|---|---|---|
| Source | Municipal water source, purified | Municipal water source, purified | Protected underground springs |
| Purification | Reverse osmosis, filtration, ozonation | Reverse osmosis, deionization, ozonation | Natural filtration process through earth |
| Minerals | Added minerals for taste | Removed, sometimes trace minerals remain | Naturally occurring minerals |
| Cost | Generally lower priced | Varies, often higher | Varies, often higher |
| Taste Profile | Consistent, but can be affected by added minerals | Varies by brand's specific process | Distinct mineral taste, varies by source |
Navigating Taste and Perceived Quality
While safety is the primary concern, consumer satisfaction also hinges on taste and quality. Factors influencing these perceptions include:
- Source Changes: If a supplier changes their water source, even within FDA guidelines, the mineral composition can alter the taste, as noted by some customers.
- Additives: The specific minerals added for taste can cause variations. The balance of calcium chloride and sodium bicarbonate, for instance, affects the overall flavor.
- Bottle Material: As some reviews mention, changes in bottle design and plastic composition can impact the water's taste and a customer's perception of quality.
Conclusion
Great Value drinking water is generally considered safe for consumption, as it is regulated by the FDA and undergoes standard purification processes like reverse osmosis and ozonation. It meets all federal and state safety standards. The primary concerns, such as microplastics and variations in taste, are not unique to the Great Value brand and are common across the bottled water industry. For those prioritizing both affordability and safety, Great Value offers a solid, federally-compliant option. For consumers with more specific concerns about microplastics or taste, exploring alternatives like filtered tap water or different brands may be warranted. As with any product, staying informed about the manufacturing process and checking the latest water quality reports can help you make the best choice for your needs.
