'I felt I killed my children': lead poisons California community – and fills kids' teeth »

For years, Terry Gonzalez-Cano encouraged her children to get outside and play in the dirt. “I grew up doing everything outside, and I encouraged my kids to do the same thing. We played in the backyard, we gardened,” she said. “I thought I was being a good mother by forcing them to spend time outside.”

Gonzalez-Cano, 48, didn’t know that, for decades, the Exide lead battery recycling plant in the neighboring Los Angeles-area city of Vernon had blanketed blue-collar Latino communities with layer after layer of lead and cancer-causing arsenic.

In June 2015, the soil on her property in the LA neighborhood of Boyle Heights was tested for lead by the California department of toxic substances control. Gonzalez-Cano said the results had come back in April 2016, 10 months after her property had been tested: her home had more than double the 80 parts per million (ppm) that California deems acceptable. At her father’s home a block away, where she and her brother spent countless hours playing in the backyard when they were children, the number averaged over 800ppm. One neighbor’s soil tested so high that it surpassed the 1,000ppm required to qualify as toxic waste.

“When I found out, I couldn’t breathe,” said Gonzalez-Cano. “I felt like I was the worst mother in the world. I felt that I had killed my children.”

Sitting next to her on the couch at her home recently, her brother Jose Gonzalez emptied a plastic bag full of bracelets from his dozens of trips to the hospital for sinus cancer on to the floor. “Here’s Exide’s legacy,” he said. “I thought I was staying fit when I used to play football in the mud. I didn’t know it, but I was poisoning myself.”

Six years after their property was tested, the siblings say that the state has not given them even a prospective timeline for when their property will be cleaned up. They worry about the damage that has already been done, and the health problems they and their families may have that will only manifest with time.

The evidence of the plant’s contamination is not just in the soil of local homes, but in the teeth of the children who inhabit them. A 2019 study found high levels of lead in the teeth of local children, indicating long-term exposure that was passed along to many while they were still in their mother’s wombs. “Mothers in these communities are exposed, and they pass that exposure on to their children before they’re even born,” said Jill Johnston, an assistant professor of preventive medicine at the University of Southern California who authored the study.

Despite its nearly 100-year presence, many in the community had never heard of Exide until less than a decade ago, although community organizers had been protesting against the plant and demanding action for many years. The company could not be reached for comment.
