It has had wide use in a wide variety of commercial products ranging from leaded gas to household paint.
Chicago Lead in Drinking Water Study

Not long after Peter and Erica Finin moved from Michigan to Pittsburgh, they had the tap water in their new home tested for lead. Test results showed they had a serious lead problem, with levels high enough to potentially harm children and infants. The Finins were one of nearly families across the country included in a study, released on Tuesday, of people who had their water tested by HBBF. That included 97 households in New Orleans, and from elsewhere in the country. Lead in drinking water remains a critical issue in the US, despite attention brought by the crises in Flint and other cities, says Jane Houlihan, research director for HBBF. Consumer Reports has long been concerned about the effects of lead, particularly on children, whose brains and bodies are still developing. Lead is ubiquitous, found in some soil, toys and ceramics, as well as some paint found in homes built before , when lead paint was banned.
Lead in Drinking Water and Human Blood Lead Levels in the United States
Many schools across the country have too much lead in their tap water, but most are not even testing for it, according to new research published Wednesday. And even in those that do test for lead, more than 40 percent of schools turned up at least one sample with higher-than-recommended levels of lead in the water. That could translate to millions of kids getting lead in the water they drink at school, the report from the Harvard School of Public Health and the Robert Wood Johnson Foundation found.
But in summer , that changed. Suddenly, Walters found that the water spewing out of her faucets was discolored and foul-tasting; her son would come out of the bath with alarming rashes. The chemistry of the water flowing through her pipes had changed profoundly—with toxic results. Walters tried to contact city and state officials for guidance, but was mostly ignored. With Walters' assistance, Edwards and his team conducted the first major study showing that lead levels in the water of more than a hundred of the city's homes exceeded safe levels in
