• Abstract:
  The Colorado Department of Transportation (CDOT) uses approximately 24,000 tons of traction sand annually,
  
  especially in mountain locations. Once traction sand is applied, street sweepers reclaim approximately 50% of the
  
  sand, which is either stockpiled at a maintenance facility or disposed of in a landfill. The remaining 50% is left on the
  
  roadway and can collect in water quality ponds and rivers due to precipitation events.
  
  This research project consolidated physical and chemical characterization data on reclaimed traction sand from
  
  multiple mountainous areas in Colorado. The Principal Investigator determined that heavy metal contamination in the
  
  reclaimed sand is within naturally occurring levels and does not pose a risk to human health through the comparison to
  
  natural background and risk-based soil values. Additional volatile organic compounds and semi-volatile organic
  
  compound characterization sampling is required for the Colorado Department of Public Health and Environment
  
  (CDPHE) to approve beneficial re-uses.
  
  A simple bench-scale composting test was conducted to determine if elevated petroleum levels could be reduced
  
  through natural bioremediation. These results indicated that the simple actions did not reduce the levels to below
  
  regulatory levels.
