Document 6: Exide lead contamination: The Exide lead contamination, in southeast Los Angeles County, California, United States, came from a battery recycling plant that emitted lead, arsenic and other dangerous pollutants over decades that contaminated as many as 10,000 homes in half a dozen working-class, Latino communities near the plant. Exide Technologies, owner of the lead-acid battery smelter located in Vernon, agreed in 2015 to close the facility while the massive cleanup of the contaminated soil will take years and cost hundreds of millions of dollars. The residents have expressed outrage over the failure of state regulators to act as the plant was allowed to operate without a full permit while documented violations were occurring. The Department of Toxic Substances Control, which allowed the plant to operate, is in charge of the cleanup and is finding that the many residents do not trust them. The residents must give them permission to test the soil around their home yet many feel betrayed by this government agency.
