The Exide battery recycling facility has caused lead and arsenic contamination in Jurupa Valley
The Exide battery recycling facility in Vernon, California, has been a source of lead and arsenic contamination in Jurupa Valley. Exide Technologies, the owner of the plant, agreed to close the facility in 2015 due to the massive cleanup of contaminated soil that will cost hundreds of millions of dollars. The plant had emitted toxic metal dust over decades, affecting as many as 10,000 homes in nearby communities. Lead is a harmful neurotoxin that can cause cognitive deficits, neurodevelopmental delays, and psychological impairments, especially in children.
Exide's battery recycling plant had a long history of environmental issues. The company acquired the plant in 2000 and filed for bankruptcy in 2020, resolving it through a federal court settlement. Prior to its acquisition, the plant had been cited as early as 1944 for releasing "poisonous, noxious" emissions. Exide itself was investigated in 2013 for emitting high levels of harmful pollutants, with hundreds of residents complaining about the toxic emissions for years before state and federal agencies took action.
The contamination resulting from the Exide plant extends beyond residential yards, with parkways and strips of land between sidewalks and streets also impacted. In 2018, county health officials traced a child's poisoning to leaded soil tracked into a home from a nearby parkway, underscoring the ongoing dangers. Researchers at USC and Occidental College tested soil samples from remediated homes and found that many still exceeded state health standards, indicating a failure in California's largest and most expensive environmental cleanup efforts.
The cleanup process has been slow and challenging. In 2019, Exide began decontaminating and deconstructing the westernmost building, known as Segment 1, where used batteries were recycled and raw materials were stored. Work on the easternmost building, Segment 2, which housed the blast furnace and lead smelting equipment, was halted in 2020 but later resumed by the Vernon Environmental Response Trust. The center building, Segment 3, containing the facility's air pollution control equipment, was completed in March 2022. The overall decommissioning process, led by the EPA and DTSC, aims to protect the community and ensure proper decontamination and deconstruction of the site.
