Objective:
Polychlorinated biphenyls (PCBs), along with polyaromatic hydrocarbons (PAHs) and organochlorine pesticides, are contaminants in the Tampa Bay area that have been monitored since 1993. Four locations in the Tampa Bay have been significantly studied including the lower Hillsborough River, the Palm River, the Alfia River, and the Little Manatee River. PCBs have been detected in extremely high concentrations in the Palm River, moderate to high concentrations in the Hillsborough River, and low to moderate concentrations in portions of upper Hillsborough Bay. Based on the areas already affected by PCBs additional work must be done in areas of the Ybor channel and the Seddon Channel. Storm water runoff and landfill leaching are considered to be likely sources of PCBs in the Tampa Bay area. PCB sediment contamination in Tampa Bay has led to morphological and histochemical changes in fish and increased defense mechanisms in oysters. Since the high levels of PCBs in the Tampa Bay area are of concern, there is a need for a low cost, effective remediation technique. This project seeks to develop the necessary technique for in situ remediation of PCBs in the Palm River.
