Dozens of California communities have experienced recent rates of childhood lead poisoning that surpass those of Flint, Michigan, with one Fresno locale showing rates nearly three times higher, blood testing data obtained by Reuters shows.
The data shows how lead poisoning affects even a state known for its environmental advocacy, with high rates of childhood exposure found in a swath of the Bay Area and downtown Los Angeles. And the figures show that, despite national strides in eliminating lead-based products, hazards remain in areas far from the Rust Belt or East Coast regions filled with old housing and legacy industry.
In one central Fresno zip code, 13.6 percent of blood tests on children under six years old came back high for lead. That compares to 5 percent across the city of Flint during its recent water contamination crisis. In all, Reuters found at least 29 Golden State neighbourhoods where children had elevated lead tests at rates at least as high as in Flint. "It's a widespread problem and we have to get a better idea of where the sources of exposure are," said California Assembly member Bill Quirk, who chairs the state legislature's Committee on Environmental Safety and Toxic Materials. Last week, prompted in part by a December Reuters investigation pinpointing thousands of lead hotspots across the country, Quirk introduced a bill that would require blood lead screening for all California children. Now, just a fraction of the state's children are tested. The newest zip code-level testing data was released by the California Department of Public Health in response to a longstanding Reuters records request and adds to a limited set of numbers previously disclosed by the state.
