Bottled Drinking Water

Short answer: Unopened bottled water can stay safe for a long time if stored correctly, but taste can change over time.

• Store sealed bottles in a cool, dark place away from chemicals and direct sunlight.
• Many manufacturers print a "best by" or manufacture date; that guidance is useful for optimal taste.
• Flavored or enhanced waters often have shorter shelf lives than plain water—check the label.
• Avoid storing bottles in hot environments (like a hot car) because heat can affect flavor and packaging.

Always follow any storage guidance on the product page or label.

Once a bottle is opened, treat it like any other opened beverage: cap it and keep it clean. Here are practical tips:

• Recap the bottle tightly between uses to limit contamination and evaporation.
• Refrigerate opened bottles when possible; cooler temperatures slow bacterial growth and keep taste fresh.
• Try to finish an opened bottle within a few days; if it sits out for long or develops an off smell or taste, discard it.
• For reuse, transfer water to a clean, reusable container designed for multiple uses rather than repeatedly refilling single-use bottles.

There isn’t a single "best" option—choice often comes down to taste and personal needs. Consider these points:

• Purified water is treated to remove impurities; many people prefer it for a neutral taste.
• Spring or mineral water contains natural minerals that influence flavor and mouthfeel.
• Sparkling water adds carbonation for variety, while flavored waters offer taste but sometimes include sweeteners or additives—check labels.
• Look at the label for mineral content or added ingredients and pick what fits your taste and dietary preferences. If you have specific health concerns, consult a professional.

You can order bottled water from Walmart online and choose delivery or store pickup where available. Here’s how to check options:

1. On the product page, enter your ZIP code to see available fulfillment options.
2. At checkout, select delivery windows or curbside/store pickup if offered in your area.
3. Same-day or scheduled delivery options may appear depending on local availability.
4. Use the Walmart app or website to track your order and see pick-up instructions; some listings also show whether contactless pickup is available.

Choosing pack size depends on guest count, event length, and conditions. Use this quick guide:

• Estimate 1–2 standard bottles (about 16–20 oz each) per person for a short gathering.
• For longer events, outdoor activities, or hot weather, plan for 2–3 bottles per person and include extra for staff or volunteers.
• Consider individual bottles for grab-and-go convenience, or larger multi-serve jugs for refill stations to reduce waste.
• Check product pages for bulk case options and delivery or pickup timing so your supply arrives before the event.
