What Bottled Water Should You Stay Away From? Brands With Documented Problems

If you want the short answer: skip any bottled water with a documented contamination record. That list includes Real Water, which the FDA pulled from shelves in 2021 after it was linked to serious liver illness, and brands such as Peñafiel and Starkey, where testing has found arsenic at or near the 10 parts-per-billion federal limit. Beyond specific names, stay away from any brand that won’t show you a current, independently verified water quality report.

The rest of this guide walks through the brands with documented problems, the red flags that should make you put a bottle back on the shelf, and what to reach for instead. Where a claim comes from a regulator or an independent lab, we link the source so you can check it yourself.

Which bottled water brands have documented safety problems?

Most bottled water sold in the U.S. is safe and regulated by the FDA under its bottled water standard of quality. The brands below are the exceptions that made headlines for the wrong reasons — each backed by a recall, regulatory action, or published third-party testing.

Real Water: the clearest “never again” on record

In March 2021, the FDA warned consumers, restaurants, and retailers to stop drinking or selling “Real Water” brand alkaline water after it was linked to an outbreak of acute non-viral hepatitis — sudden liver injury — in the Las Vegas area, including cases in children. The company recalled its products and later ceased operations. It remains the starkest modern example of why “alkaline” and “premium” labels are not safety guarantees. If you live in the region where it was sold, our Nevada drinking water guide covers what’s actually in local tap water.

Peñafiel: arsenic above the federal limit

Peñafiel, a Mexican mineral spring water imported by Keurig Dr Pepper, drew scrutiny in 2019 when testing — including the company’s own — found arsenic levels above the FDA’s 10 ppb standard of quality. Keurig Dr Pepper suspended production at the source for two weeks and added enhanced filtration. Consumer Reports, which had flagged the brand in its arsenic testing, urged a recall. Arsenic is a known carcinogen with no beneficial level, which is why regulators cap it aggressively.

Starkey (Whole Foods): arsenic just under the line

Starkey Spring Water, sold by Whole Foods, was recalled in 2016–2017 after samples exceeded the arsenic limit, and Consumer Reports testing in 2019 measured samples approaching the 10 ppb ceiling — higher than nearly every competing brand. Legal? Yes. But when dozens of brands test at 1 ppb or below, there’s little reason to choose one that hovers near the maximum.

Topo Chico: the PFAS outlier that (mostly) cleaned up

In Consumer Reports’ 2020 testing of 47 bottled waters, Topo Chico mineral water registered the highest total PFAS (“forever chemicals”) of any brand tested, at 9.76 parts per trillion. After Coca-Cola upgraded the brand’s filtration, a 2021 retest showed levels cut roughly in half — better, but still above the 1 ppt threshold some health advocates recommend. Worth knowing: the EPA’s tough new PFAS limits apply to public tap water, not bottled water, and the FDA has not set an enforceable PFAS limit for bottled products.

What’s the unhealthiest type of bottled water?

Brand names aside, some categories deserve extra caution:

• Sweetened and “flavored” waters. Many are closer to soft drinks than water. Check for added sugars and acids that erode tooth enamel.
• Repackaged municipal water at premium prices. Brands labeled “purified water” often start as tap water. That’s not a safety problem — it’s a value problem, especially if the brand won’t disclose its source.
• Bottles stored hot or sold dusty. Heat accelerates leaching from plastic and degrades taste. Skip bottles that have clearly baked in a warehouse, vehicle, or sunny storefront.
• Any bottle, if it’s your everyday default. Research has repeatedly found microplastic particles in the majority of bottled water samples tested. Health effects are still being studied, but if you drink bottled water daily, that’s an avoidable exposure.

Red flags: how to spot a bottled water to skip

Use this quick checklist in the store:

• No published water quality report. Reputable bottlers publish current test results (often called a water quality or consumer confidence report) on their website. No report, no purchase. Our roundup of independently tested bottled water brands lists the ones that do this well.
• Vague sourcing. “Bottled at the source” means little if the label won’t say where the source is.
• Arsenic-prone volcanic springs without recent test data. Several problem brands share this geology. It’s manageable with treatment — but only if the bottler tests and publishes.
• Miracle health claims. “Structured,” “oxygenated,” or extreme-alkalinity marketing is a reliable signal that marketing is outrunning chemistry. Real Water advertised an “E2 ionization” process right up until the FDA intervened.

Which bottled water is actually safe to drink?

The good news: most major brands test far below every federal limit. Look for bottlers that publish current reports, carry NSF or IBWA certification, and consistently post low arsenic, low PFAS results. We keep a regularly updated ranking in our guide to the safest bottled water brands in America, and a broader overview on our bottled and drinking water pillar page.

Is your tap water the better option?

Often, yes — and it’s dramatically cheaper. U.S. tap water is regulated by the EPA with mandatory public reporting, and in most systems it meets every health standard. Quality varies by region, though: see our state-by-state breakdown at the drinking water quality by state hub, or jump straight to a state like Texas if that’s home.

Two practical moves beat brand-hopping:

• Test what’s in your tap. A certified-lab kit like SimpleLab’s Tap Score (mytapscore.com) screens for arsenic, lead, PFAS, and dozens of other contaminants, so you’re deciding on data instead of marketing.
• Filter instead of buying bottles. A quality reverse osmosis system removes arsenic and most PFAS at a fraction of bottled water’s per-gallon cost. Aquasana’s under-sink and whole-house systems (aquasana.com) and Crystal Quest’s reverse osmosis line are both solid starting points.

Frequently asked questions

What bottled water was recalled for making people sick?

Real Water alkaline water. The FDA linked it to an outbreak of acute non-viral hepatitis in 2021; the brand was recalled nationwide and the company shut down. It is no longer sold.

Is Topo Chico still high in PFAS?

It’s improved. After registering the highest PFAS level in Consumer Reports’ 2020 test, Coca-Cola upgraded filtration and a 2021 retest showed levels roughly halved. It’s no longer the outlier it was, but it isn’t the lowest-PFAS option either.

How much arsenic is allowed in bottled water?

The FDA’s standard of quality is 10 parts per billion, matching the EPA’s limit for tap water. Many brands test at or below 1 ppb, so there’s no need to accept a brand near the ceiling.

Does the EPA regulate bottled water?

No. The EPA regulates public tap water; bottled water is regulated by the FDA as a packaged food. FDA standards largely mirror EPA’s, but bottled water has no enforceable federal PFAS limit and less frequent mandatory public reporting.

Is bottled water safer than tap water?

Not inherently. Both are generally safe in the U.S., but tap water rules require more public disclosure. The right answer for your household depends on your local system — check your state’s page on our state water quality hub or test your tap directly.

What should I do if I bought a recalled or flagged brand?

Stop drinking it, keep the receipt and lot number, and check the FDA’s recall database for instructions. Retailers refund recalled products, and the FDA accepts consumer reports of suspected illness linked to bottled water.
