November 16, 2011, 1:00 PM - 3:00 PM, EST (18:00-20:00 GMT)

Dr. Burken will present his work using traditionally high pressure waterjet in a new and innovative manner to inject remediation amendments such as powdered activated carbon at varying depths in contaminated sediments. This method also decreases contaminant bioavailability and minimizes resuspension and the impact on benthic communities. Waterjet placement can be applied for a suite of amendments targeting nearly all common sediment contaminants, specifically polychlorinated biphenyls (PCB), polycyclic aromatic hydrocarbons (PAH), and redox sensitive metals. In addition, the waterjet can be used for sediments with overlaying caps.
