About 129,000 Chicago children under the age of six are exposed to poisonous lead in their household drinking water because of lead pipes, according to a study published on Monday.
The study used artificial intelligence to analyse 38,000 home water tests conducted for the city of Chicago, along with neighborhood demographics, state blood samples and numerous other factors.
It found that Black and Latino residents are more likely to have lead-contaminated water because of lead pipes. And it estimated that the 19% of Chicago children who use unfiltered tap water as their primary drinking source have about twice as much lead in their blood as they would otherwise.
“These findings indicate that childhood lead exposure is widespread in Chicago, and racial inequities are present in both testing rates and exposure levels,” said the study, published by the Johns Hopkins Bloomberg School of Health in Jama Pediatrics. “We estimated that more than two-thirds of children are exposed to lead-contaminated drinking water.”
