• 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.
