The Toxic Sludge Experiment of Baltimore and St. Louis
In the year 2000, Federally funded researchers from John Hopkins University, the EPA, HUD, The Kennedy Krieger Institute and Department of Agriculture spread sludge from a sewage treatment plant on the lawns of nine low-income families, and a vacant lot in Baltimore and East St. Louis. The families and residents were told the sludge was safe and not informed about the toxic mixture of human and industrial waste the sludge contained. The research was conducted to see if the toxic waste absorbed into the water supply could effectively reduce lead levels in children.
