Napa Valley landfill dumped toxic waste into waterways for decades, workers allege in federal lawsuit

By Shannon Kelleher

A California landfill has been illegally dumping toxic waste into the Napa River for years, polluting waters that feed a valley known around the world for the quality of its vineyards, according to a federal lawsuit filed by landfill employees.

Fifteen workers from Clover Flat Landfill and Upper Valley Disposal Service (UVDS) in Napa County, California, allege that operators of the landfill intentionally diverted what is called “leachate” – untreated liquid wastewater often containing heavy metals, nitrates, bacteria and pathogens – into the Napa River and other area waterways for decades. The actions were done to “avoid the costs of properly trucking out the toxic leachate” to facilities designated for safe disposal, the lawsuit alleges.

“Defendants’ deliberate pollution of the Napa River watershed with toxic wastewater is particularly disturbing because Napa Valley contains some of the most valuable agricultural land in the country, and water from the Napa River is used by local wineries to irrigate Napa’s famous vineyards, and is a significant community water resource,” the complaint said.

The workers say the practice not only endangered the public but created unsafe working conditions, exposing the employees to “toxic chemicals, pollution, and poisons” without providing employees proper protective gear.

The action, which was filed Oct. 28 in US District Court in San Francisco, seeks more than $500 million in damages and names as defendants both current owner Waste Connections, a nationwide waste management company, as well as the facilities’ former owners.
