1Keurig Dr PepperAs the parent company of Peñafiel, Keurig Dr Pepper oversees the brand's response to 2019 quality issues. Success is defined by monitoring their ongoing commitments to safety and environmental standards following those past events.
Peñafiel—a prominent Mexican mineral water and soft drink brand owned by Keurig Dr Pepper (KDP) —has a reputation that has faced notable scrutiny regarding quality control, product safety, and broader corporate environmental responsibility.
The brand’s standing in these areas is defined by a few major milestones and systemic concerns:
Arsenic Contamination and Voluntary Withdrawals: Peñafiel's reputation for bottling and quality assurance took a severe hit in 2019 . Testing by independent watchdogs, including Consumer Reports and the California-based non-profit Center for Environmental Health (CEH), found that certain unflavored mineral spring water batches contained levels of arsenic exceeding federal and state safety limits. Keurig Dr Pepper subsequently enacted a voluntary market withdrawal of the affected products and faced subsequent class-action litigation alleging that the company allowed contaminated water to reach store shelves.
Peñafiel’s reputation is mixed on bottling/quality control and more positive—but qualified—on environmental sustainability. The key distinction is between its historical quality issue and the more recent sustainability initiatives.
Peñafiel—a prominent Mexican mineral water and soft drink brand owned by Keurig Dr Pepper (KDP) —has a complex reputation regarding its bottling practices, product safety, and environmental impact.
Peñafiel—owned by Keurig Dr Pepper—has a reputation marked by standard commercial bottling practices, but it faced major scrutiny and reputational damage due to a 2019 arsenic contamination controversy rather than widespread, distinct corporate leadership in environmental sustainability
Peñafiel’s reputation is mixed on bottling quality and improving—but not exemplary—on sustainability.
In 2019, U.S. testing found arsenic above the FDA limit, prompting a voluntary withdrawal and enhanced filtration. The recall was completed, but the episode damaged confidence in quality control.
Corporate Water Stewardship vs. Local Scarcity: Operating and sourcing spring water in Mexico places Peñafiel directly inside a complex landscape of severe regional water stress. While parent company Keurig Dr Pepper publishes corporate ESG initiatives—such as water efficiency tracking, watershed protection, and local replenishment partnerships in regions like Jalisco—multinational bottling operations in Mexico frequently face broader public skepticism. Activists and local communities often criticize heavy industrial extraction by large beverage conglomerates amid chronic municipal shortages and climate-aggravated droughts.
Plastics and Packaging Footprint: Like most mass-market bottled beverage brands, Peñafiel relies heavily on single-use plastic (PET) and glass formats distributed globally and across North America. Environmental groups routinely critique these packaging lifecycles for contributing to persistent plastic pollution, placing pressure on KDP to accelerate circular-economy commitments and plastic reduction targets.

The biggest reputational blemish is the 2019 arsenic incident.
In April 2019, independent testing commissioned by Consumer Reports found elevated arsenic in Peñafiel mineral water. The U.S. FDA subsequently documented that Keurig Dr Pepper voluntarily withdrew the unflavored Peñafiel products because some samples exceeded the FDA’s 10 ppb arsenic limit. The withdrawal was later completed and the FDA terminated the recall.
There was an important regulatory discrepancy: Mexico's Profeco tested samples shortly afterward and found 4–5 ppb, below Mexico's 10 ppb limit, concluding that the tested product did not pose a health risk.
KDP subsequently reported that it suspended Peñafiel production, installed enhanced filtration, and increased monitoring.
So the evidence doesn't support saying that Peñafiel routinely produces unsafe water. But the 2019 episode is a legitimate reason the brand's quality-control and monitoring reputation took a hit, particularly because testing produced different results in the U.S. and Mexico.
Environmental sustainability
Here, the evidence is considerably more encouraging.
Packaging: KDP currently says Peñafiel's single-serve bottles contain at least 30% recycled PET (rPET). www.keurigdrpepper.com That's a meaningful reduction in virgin-plastic demand, although it doesn't eliminate the environmental impact of disposable bottles.
Returnable glass: This is probably Peñafiel's most interesting sustainability practice. KDP reports that its Tehuacán operation has decades of experience with refillable glass bottles, and that production volume in this reusable format rose substantially in the years preceding its 2023 report. keurigdrpepper.com Peñafiel has also continued promoting returnable-glass packaging in Mexico.
Plant waste and water: Peñafiel reports substantial recent progress. For 2025, the company reported programs involving water efficiency, ecosystem restoration and waste reduction; independent trade publications reporting company data say the Tehuacán plant recycled more than 99.5% of its waste during 2025 and saved more than 2.5 million liters of water. ganar-ganar.mx These are encouraging figures, although they're primarily company-reported, rather than an independently verified lifecycle assessment.
KDP's broader corporate program also reports that 96% of its overall packaging was recyclable or compostable in 2025 and that virgin plastic across its portfolio had fallen 21% since 2019. Those figures cover KDP as a whole, so they shouldn't be treated as Peñafiel-specific.

Improving, but not unambiguously “green”
Bottom line: I would describe Peñafiel as a brand that recovered from a significant historical bottling-quality controversy and has subsequently made credible sustainability improvements. Its returnable-glass system and recycled-PET bottles are meaningful positives. However, most Peñafiel sold in single-serve bottles remains disposable PET, and corporate sustainability claims don't by themselves establish a low overall environmental footprint.
If you're evaluating Peñafiel specifically for ethical/environmental purchasing, the most important comparison would be Peñafiel vs. other bottled-water brands on recycled content, refillable packaging, water sourcing, and corporate environmental disclosures.
Peñafiel’s reputation is mixed on bottling quality, but more positive on environmental efforts—with an important distinction between Peñafiel-specific practices and the broader sustainability record of its parent, Keurig Dr Pepper (KDP).
Bottling practices and quality
The biggest reputational issue was a 2019 arsenic-related withdrawal. KDP voluntarily withdrew unflavored Peñafiel mineral water in the U.S. after independent testing found arsenic above the FDA’s 10-ppb bottled-water standard. The FDA says the recall was subsequently completed and terminated. KDP also said it had installed enhanced filtration at the facilities producing Peñafiel.
That incident is a meaningful blemish on Peñafiel's quality-control reputation, but it doesn't establish that the brand's current products are unsafe. The issue involved naturally occurring arsenic in the source water, and the company reported corrective filtration measures. In other words, the record is better characterized as a significant historical quality-control incident followed by corrective action, rather than a continuing documented problem.
Environmental sustainability
There are several concrete positives:
Recycled PET: KDP currently says Peñafiel single-serve bottles contain at least 30% post-consumer recycled PET.
Refillable glass in Mexico: KDP reports that its Tehuacán operation has more than 70 years of experience with refillable glass bottles. Beverage volume in this reusable format increased by 90% over the five years preceding its 2023 report, including Peñafiel products.
Broader packaging improvements: Across KDP—not Peñafiel alone—the company reported that 96% of its packaging was designed for recyclability or compostability in 2024, while virgin-plastic use was 17% below its 2019 baseline.
There is also a longer history of environmental projects associated with Grupo Peñafiel, including reforestation and water-conservation/agricultural initiatives around Tehuacán.
The caveat is that recycled PET doesn't eliminate the environmental footprint of disposable bottled water. Production of plastic, transportation, and end-of-life collection still matter. And KDP's corporate sustainability statistics shouldn't automatically be interpreted as Peñafiel-specific performance.
Overall reputation
I'd summarize it this way:
Area
What the evidence suggests
Bottling/quality
Mixed — serious 2019 arsenic incident, followed by corrective filtration and a completed recall
Current documented safety
No evidence in the sources reviewed of a continuing Peñafiel arsenic problem
Single-use packaging
Improving, but still environmentally burdensome
Recycled content
Concrete positive — ≥30% recycled PET in single-serve bottles
Refillable packaging
So, if you're assessing Peñafiel as a brand, its environmental reputation is improving rather than exemplary: its recycled-PET and refillable-glass programs are genuine sustainability measures, while the 2019 arsenic episode remains the most significant negative event in its bottling history.
If you're considering buying Peñafiel specifically, I can also compare it with brands such as Topo Chico, Perrier, San Pellegrino, or Liquid Death on water quality, packaging, recyclability, and environmental record.
1. Bottling Practices and Product Quality Controversies
The Arsenic Controversy: Peñafiel’s reputation suffered a major blow when testing by Consumer Reports and advocacy groups revealed that unflavored Peñafiel mineral water contained levels of arsenic exceeding federal standards.
Voluntary Withdrawals and Lawsuits: Following the public exposure, Keurig Dr Pepper faced class-action lawsuits alleging they knew about elevated mineral/arsenic levels well before taking action. KDP subsequently issued a voluntary withdrawal of unflavored Peñafiel mineral spring water and stated they installed enhanced filtration systems at their production facilities to bring the water safely within regulatory guidelines.
2. Environmental Sustainability and Extraction Concerns
Intensive Groundwater Extraction in Tehuacán: Peñafiel sources much of its iconic mineral-heavy water from the volcanic region of Tehuacán, Puebla. Large-scale commercial bottling in this region has historically drawn scrutiny from local communities and environmental observers who worry about the depletion of local aquifers and water stress, a systemic issue facing bottled water operations throughout Mexico.
Corporate Sustainability Goals: As a brand under Keurig Dr Pepper, Peñafiel's overarching environmental footprint is tied to KDP’s corporate ESG (Environmental, Social, and Governance) commitments. This includes ongoing targets for plastic waste reduction, utilizing more recyclable PET packaging, and improving water stewardship efficiency across manufacturing plants (such as upgrading the Tehuacán plant with advanced German bottling tech that optimizes resource usage). However, like most major single-use plastic bottled beverage brands, it faces persistent criticism from environmental coalitions regarding plastic pollution and the inherent ecological toll of mass-market bottled distribution.

The biggest blemish is the 2019 arsenic incident. Testing commissioned by Consumer Reports found arsenic in Peñafiel unflavored mineral water at nearly twice the U.S. FDA limit. Keurig Dr Pepper subsequently voluntarily withdrew the affected 600-mL and 1.5-L products from the U.S. market. The FDA says that withdrawal/recall was completed and terminated.
There is an important counterpoint: Mexico's consumer-protection agency, Profeco, tested Peñafiel samples around the same time and found 4–5 ppb arsenic, below Mexico's 10-ppb limit. Profeco reported that Peñafiel was improving filtration at its plants and increasing sampling frequency.
Keurig Dr Pepper says it subsequently suspended production at Peñafiel facilities and installed enhanced filtration systems, with the product being produced afterward within regulatory guidelines.
So the historical reputation isn't really “Peñafiel routinely bottles unsafe water”; rather, the 2019 episode exposed weaknesses or inconsistencies in monitoring and quality control and damaged consumer confidence.
Environmental sustainability
Here the picture is more positive, although there are still obvious limitations inherent in selling bottled water.
Recycled PET: Peñafiel single-serve bottles currently contain at least 30% recycled PET, according to parent company Keurig Dr Pepper.
Refillable glass: In Mexico, KDP maintains a substantial returnable-glass system. Its Tehuacán facility has decades of experience with refillable bottles, and KDP says the volume of beverages sold in this reusable format increased 90% over the five years through 2023; this includes Peñafiel products.
Corporate water stewardship: KDP has broader programs aimed at water replenishment and watershed conservation, though these are KDP-wide initiatives rather than measures attributable solely to Peñafiel.
The basic environmental trade-off remains: disposable PET, even when partly recycled, still involves plastic production, transportation, and eventual waste. Recycled content and recycling initiatives reduce that footprint but don't eliminate it.
Overall
I'd characterize Peñafiel as having a significant historical quality-control controversy followed by documented corrective measures, alongside improving but imperfect environmental practices. Its use of recycled PET and especially its refillable-glass infrastructure in Mexico are meaningful positives. On the other hand, it would be misleading to treat Keurig Dr Pepper's broader sustainability achievements as proof that every aspect of Peñafiel's environmental footprint is exemplary.
If you're considering whether Peñafiel is a relatively responsible bottled-water choice, the most useful comparison would be against other bottled-water brands on PET content, refillable packaging, water sourcing, and environmental reporting rather than relying on the brand's sustainability claims alone.
Arsenic Levels (2019): Peñafiel's reputation took a significant hit when independent testing and public health reports revealed that its unflavored mineral spring water contained arsenic levels reaching 17 parts per billion (ppb), exceeding the FDA standard limit of 10 ppb.
Voluntary Withdrawal: Following pressure from consumer advocates and media reports, Keurig Dr Pepper initiated a voluntary withdrawal of unflavored Peñafiel products and temporarily suspended production to upgrade filtration systems at its plants in Mexico.
Corrective Action: The company stated that subsequent production runs met regulatory limits after installing enhanced filtration infrastructure, though the event remains a primary talking point in the brand's modern quality history.
Environmental Sustainability and Packaging
Plastic Reliance: Like most major commercial mineral water and soda brands, Peñafiel relies heavily on PET plastic bottles for its core distribution, contributing to standard industry criticisms regarding single-use plastics and lifecycle carbon footprints.
Parent Company Framework: Peñafiel does not maintain a standalone public profile or distinct reputation for pioneering environmental stewardship; instead, its ecological footprint and sustainability goals fall entirely under Keurig Dr Pepper's corporate responsibility umbrella, which targets general packaging recyclability and water use efficiency across all beverage lines rather than specific localized conservation for Peñafiel springs.

Peñafiel—a historic Mexican mineral water and beverage brand owned by Keurig Dr Pepper (KDP) —has a reputation shaped by a major quality control crisis, as well as broader scrutiny facing the commercial bottled water and beverage industry in Mexico.
1. Bottling Practices and the 2019 Arsenic Controversy
The Arsenic Crisis: Peñafiel’s reputation regarding bottling and product safety took a severe hit following investigations and reports (notably by Consumer Reports and the non-profit Center for Environmental Health ) revealing that unflavored Peñafiel mineral spring water contained levels of arsenic exceeding the U.S. Food and Drug Administration (FDA) standard of 10 parts per billion (ppb), averaging around 17 to 18 ppb.
Voluntary Withdrawal: In response to the public pressure and findings, Keurig Dr Pepper issued a voluntary market withdrawal of unflavored Peñafiel mineral spring water formats in mid-2019.
Corrective Action: KDP stated that it installed enhanced filtration and advanced water-treatment systems at its production facilities in Mexico to screen and lower arsenic to comply strictly with regulatory guidelines. While the immediate crisis was managed through the recall and infrastructure updates, the incident remains a notable blemish in the brand's long history regarding baseline quality assurance and source-water monitoring.
2. Environmental Sustainability and Water Stewardship
Corporate Oversight: As part of Keurig Dr Pepper, Peñafiel benefits from corporate-level sustainability frameworks. KDP tracks enterprise-wide water efficiency, targets positive water impact milestones, and engages in watershed protection and replenishment projects in various operational regions.
Broader Industry Pressures in Mexico: Like other major multinational and national beverage giants operating in Mexico (such as Coca-Cola and Danone), Peñafiel extracts water from ecologically sensitive and increasingly water-stressed regions. Mexico faces profound water scarcity and severe droughts across multiple states.
Public Perception: While KDP publishes corporate responsibility goals focusing on water optimization and local community access, large-scale industrial groundwater extraction for commercial bottling in water-vulnerable regions of Mexico frequently draws criticism from local communities, environmental activists, and watchdogs pointing toward systemic aquifer depletion.
If you'd like, I can dive deeper into:
Keurig Dr Pepper's broader corporate ESG metrics and water replenishment goals
Specific details on geological arsenic occurrence in Mexican mineral springs
The regulatory frameworks governing bottled water in Mexico versus the US
Sustainability: Peñafiel’s single-serve bottles now contain at least 30% recycled PET, while its parent, Keurig Dr Pepper, reports broader water-stewardship and packaging initiatives.
Caveat: These improvements mitigate, rather than eliminate, the environmental impact of disposable plastic bottles.
Overall, I’d describe Peñafiel as having recovered from a notable historical quality-control problem, with credible but incomplete sustainability progress.
Peñafiel—a popular Mexican mineral water and beverage brand owned by Keurig Dr Pepper (KDP) —has a reputation shaped less by aggressive grassroots environmental controversies (which have more intensely targeted competitors like Danone’s Bonafont in central Mexico) and more by major product quality and safety incidents.
The general standing of Peñafiel regarding its bottling, quality control, and environmental footprint reflects several key dimensions:
The 2019 Arsenic Contamination and Quality Crisis: Peñafiel’s reputation took a severe hit when independent testing by the non-profit Center for Environmental Health (CEH) and Consumer Reports revealed that unflavored Peñafiel mineral spring water contained levels of arsenic exceeding federal limits set by the U.S. FDA and California's Proposition 65. This forced Keurig Dr Pepper to announce a voluntary market withdrawal/suspension of the product. While arsenic can naturally occur in volcanic or mineral-heavy aquifers where mineral water is sourced, the incident heavily damaged consumer trust regarding the brand’s quality control and purity standards in bottling.
Corporate Water Stewardship Framework: As part of Keurig Dr Pepper , relies on the parent company's broader corporate social responsibility (CSR) and water stewardship guidelines. KDP outlines corporate targets aimed at improving water use efficiency in manufacturing, supporting watershed protection, and boosting recycling infrastructure. However, like many multinational-owned beverage lines operating in water-stressed regions of Mexico (such as Puebla and surrounding central/eastern regions), the broader corporate practice of drawing heavy volumes of mineral-rich groundwater faces the general, systemic criticism aimed at the bottled water industry as a whole—namely, extracting local public liquid assets for export and commercial profit.
Would you like to explore Keurig Dr Pepper's corporate sustainability report or dive deeper into how mineral water aquifers naturally accumulate elements like arsenic?
Peñafiel’s reputation is mixed but not uniformly negative. The biggest blemish is a serious 2019 bottling-quality incident; on sustainability, the brand has made tangible improvements, but it still relies substantially on disposable PET bottles.
Bottling practices and product quality
The most important event was in 2019, when Keurig Dr Pepper voluntarily withdrew Peñafiel unflavored mineral water from the U.S. after independent testing found arsenic above the FDA’s 10-ppb bottled-water standard. The affected products were 600-mL and 1.5-L PET bottles. The FDA says the recall was subsequently completed and terminated.
KDP said it suspended production at Peñafiel facilities and installed enhanced filtration systems, after which the water being produced was within regulatory guidelines.
There was also criticism surrounding the episode: Consumer Reports reported that FDA records indicated the agency had been aware of elevated arsenic results involving Peñafiel several years before the 2019 withdrawal.
So I would characterize Peñafiel's bottling reputation as “a significant historical quality-control problem followed by corrective action,” rather than a brand generally known for poor bottling practices.
Environmental sustainability
The picture is more favorable, particularly under KDP's current sustainability program.
Recycled PET: KDP currently says Peñafiel single-serve bottles contain at least 30% recycled PET (rPET).
Refillable glass: In Mexico, KDP maintains refillable glass-bottle operations where collection, sanitation and refilling infrastructure exists. Its 2023 report says its Tehuacán plant has more than 70 years of experience with refillable glass and that beverage volume in this format increased 90% over the preceding five years. The program includes Peñafiel flavors and mineral water.
Water stewardship:Grupo Peñafiel has a longer history of water-conservation initiatives, including efforts to reduce water consumption and wastewater and community water-awareness programs.
Broader packaging improvements: KDP reports that in 2025, 96% of its packaging was recyclable or compostable and that virgin-plastic use across its portfolio had fallen 21% from 2019. These are KDP-wide figures, however—not -specific performance.

Bottom line: I wouldn't describe Peñafiel today as an inherently unsafe or environmentally irresponsible brand. Its 2019 arsenic episode is a legitimate reason for caution about its historical quality controls, but the subsequent filtration and monitoring measures are significant. Environmentally, its use of recycled PET and established refillable-glass infrastructure are positives, while the continued use of single-use plastic and the resource demands of bottled water remain drawbacks.
For someone choosing bottled water specifically on environmental grounds, I'd rate Peñafiel as better than its historical reputation suggests, but still clearly behind reusable/refillable alternatives.
Substantial corporate programs, but some claims are KDP-wide rather than Peñafiel-specific
Peñafiel
Packaging and Plastic Footprint: Peñafiel relies heavily on traditional single-use polyethylene terephthalate (PET) plastic bottles and glass formats. While its parent company publishes sustainability metrics regarding recycled content goals and lightweighting bottles, the brand remains associated with the widespread environmental criticisms targeting plastic pollution and the massive carbon footprint of shipping heavy bottled mineral water internationally from Mexico to markets in the United States.
