Class action lawsuit claims Mountain Valley Spring Water contains carcinogens

Mountain Valley Spring Water class action overview:

• Who: A consumer is suing Primo Water Corp., Primo Water North America Inc. and Mountain Valley Spring Co. LLC.
• Why: The plaintiff alleges Mountain Valley Spring Water is falsely advertised free of pollutants when it actually contains carcinogens.
• Where: The Mountain Valley Spring Water class action was filed in Florida federal court.

A new class action lawsuit claims Mountain Valley Spring Water is falsely marketed as purely sourced and free of pollutants when it actually contains multiple carcinogens.

Plaintiff Jeffrey Nadel filed the class action complaint against Primo Water, Primo Water North America and Mountain Valley Spring in Florida federal court, alleging violations of state and federal consumer laws.

According to the lawsuit, Mountain Valley Spring Water is marketed as “America’s Premium Spring Water” and “the very best bottled water you can drink,” commanding premium prices 4-8 times the cost of standard bottled water.

The lawsuit states these premium prices are justified through claims of “purely sourced” water that is “free of pollutants” and “exceptionally healthful,” with emphasis on the water’s “3,500-year natural filtration.”

However, independent laboratory testing in July 2025 allegedly detected arsenic, uranium and bromoform, which are substances with U.S. Environmental Protection Agency Maximum Contaminant Level Goals of zero, meaning no safe level for human consumption.

The lawsuit alleges the presence of bromoform, a chlorination byproduct, indicates likely undisclosed chlorine-based treatment, contradicting the defendants’ disclosed ozonation/UV processes.

The lawsuit further claims that Mountain Valley may have known about the contamination and concealed it, as the company experienced a supply shortage coinciding with viral social media posts exposing the issue.

Consumers paid premium prices for contaminated water, lawsuit says

Nadel says he and other health-conscious consumers paid substantial premiums believing they were purchasing “the very best bottled water you can drink” — water that was “purely sourced” and achieved through natural processes without additives.

Instead, they received water containing detectable carcinogens and disinfection byproducts, the lawsuit alleges.

Nadel seeks to recover the premium prices consumers paid based on the defendants’ false promises and to prevent them from continuing to deceive the public about the true nature of their water.

The lawsuit is looking to represent anyone who bought Mountain Valley Spring Water in glass bottles from retail stores for personal, family or household use during the period from June 7, 2023, through the date of class certification.

Nadel is suing for violations of state and federal consumer laws and seeks certification of the class action, damages, fees, costs and a jury trial.

In 2024, a Nevada jury awarded $230 million in damages to 15 plaintiffs who said they suffered liver damage from drinking Real Water’s alkaline water.
