The Sludge War is a five-year investigative documentary that begins when a young woman discovers her home was built on a toxic substance deliberately buried there. Following a hidden trail of evidence from rural towns to major cities across America, she uncovers one of the most well-hidden environmental cover-ups in U.S. history. For more than fifty years, this dangerous practice has been concealed beneath homes, schools, parks, and athletic fields, quietly affecting the health of millions of Americans.
