California Sues Walmart, Says It Illegally Dumps Batteries, Other Toxic Waste in Landfills

California filed a lawsuit against Walmart Monday, with state prosecutors claiming the retail company illegally dumps over one million batteries, aerosol cans of insect killer, toxic cleaning supplies and more into landfills annually.

"Pesticides, electronics, household hazardous waste must be disposed of properly, or they can be released into our air, our water and soil resulting in a number of negative health outcomes — including cancer, neurological disorders, asthma, or learning disabilities," said California Department of Toxic Substances Control Director Meredith Williams during a news conference announcing the lawsuit.

The state conducted 58 inspections in 13 counties of trash compactors taken from Walmart stores from 2015 to 2021. Dozens of products considered hazardous waste, medical waste, or customer records with personal information were discovered in every case, California Attorney General Rob Bonta said.

"As we shop the brightly packed aisles there are products that will never make it into the cart — returned, damaged, or pulled from the shelves for a variety of reasons," said Bonta.

"When a big box store disposes of unwanted goods, just like the rest of us, they need to do so properly. Unfortunately, Walmart — the largest company in the world by revenue — has failed to do that on a grand scale here in California," Bonta said.

Walmart will fight the "unjustified lawsuit" filed, company spokesperson Randy Hargrove said.

"The state is demanding a level of compliance regarding waste disposal from our stores of common household products and other items that goes beyond what is required by law," Hargrove said.

The attorney general's office settled a previous similar lawsuit in 2010 in which Walmart, which operates more than 300 stores in California, paid $25 million and agreed to stop the dumping into local landfills that are not equipped to contain the hazardous products.

It paid $1.25 million to Missouri in 2012 to settle a similar lawsuit.

And in 2013, the company pleaded guilty to six federal misdemeanors of negligently discharging a pollutant into drains in 16 California counties, part of an $81 million deal that also included charges in Missouri.

Hargrove said a judge was ready to sign off in 2018 on Walmart's compliance under the 2010 settlement until the attorney general's office started a new investigation with "new rules" in a bid to force a new settlement.

More than 3,800 audits overseen by the attorney general's office since 2010 found that Walmart's trash compactors "contain at most 0.4% of items of potential concern," compared to a statewide average of 3%, Hargrove said: "Our compactors are far cleaner than the state average."

Bonta said Walmart's own inspections show it illegally disposes of nearly 80 tons of such waste each year, which his office estimated amounts to more than 1 million individual items.

The attorney general's office was joined in the lawsuit by Williams' agency and the district attorneys of Alameda, Fresno, Monterey, Orange, Riverside, Sacramento, San Bernardino, San Diego, San Joaquin, Solano, Tulare, and Yolo counties in filing the lawsuit.

By contrast with Walmart, Bonta said other large retailers have disposal practices that comply with state laws "to different degrees, some with great compliance."

"It's not rocket science," he said. "You can't be sending these hazardous waste products into the general stream of sanitation. It's dangerous, it's unhealthy."

Williams added that "other companies manage to comply with those laws," while Walmart has even more means and incentive based on its prior violations.

"So it's really quite astounding that they continue to violate these hazardous waste control laws," she said.
