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.

I have purchased Mountain Valley Water for many years. First by delivery and the last 5 years at my local grocery store. I have noticed a change in the taste of the water in the last year. Very sad to hear of these claims. Please share the information and count me in if it validates.

I started buying 12 x 1/liter bottles of mountain valley spring water for my family.. I have a 5 year old son with autism as well as a 16 year old daughter who had to get plasma exchange as a child due to encephalitis. We’ve been buying around at a case of one litre bottles per week due to claims that your water was clean! Please feel free to contact me as soon as possible, I can’t believe just how corrupt this is. Is there any water out there that is actually clean. My family had faith in your water for years and now things have been getting worse and I find this out?!
Please add me to this class action for mountain valley spring water of which I purchased many cases last year and have all of my receipts

I have been purchasing mt valley glass bottles for years. Especially the 5 gallon ones, approx. 3 per month. I just saw this information. I was searching online because I feel the water does not taste good like it used to. I have had water with sedime t in the bottom, too.
I’ve noticed the quality has gone down since mountain valley spring sold out to primo. It used to be a local company in Hot Springs, but as everything happens when big money comes in, something clearly changed.
My wife and I have been buying and drinking Mountain Valley Spring water for last 11 or 12 years. We are deeply angry about this and want to be part of this class action suit.
