Residues containing Cr (VI) are classified as toxic and hazardous residues by the US Environmental Protection Agency (EPA). Cr (VI) could easily leach into the environment due to rain water passing through the Cr (VI), containing residues which could lead to ground water contamination if these residues are land filled without prior treatment. This book synthesizes and provides an overview of past, state-of-art research across the field of minimization, recovery, recycling and inertization of residues containing Cr (VI) and where the field is headed.
