Charleston, South Carolina

• Problem - PAHs in soil from a manufactured gas plant - An urban Superfund site with limited area for in-situ remediation - Possible brackish shallow groundwater.
  
  
• Solution – Performed a greenhouse study to select saline-tolerant hybrids. Install phytoremediation consisting of hybrid poplars planted into contaminated soils.
  
  
• Traditional Technology Replaced - Soil excavation and disposal - Follow-up monitoring has documented PAH concentration reduction.
