VIMS presence in Portsmouth
• Elizabeth River Project, Board of Directors 16 years.
• Technical assistance, Portsmouth Wetlands Board
• Designs for wetlands at 4 Norfolk Naval Shipyard superfund sites.
• PAH toxicity and clean up, new technology. • PAH toxicity and clean up, new technology.
• Port expansion at Craney Island - modeling and mitigation.
• Continuing tide sensing for circulation and storm surge modeling.

Creosote-another source for PAHcoal-tar distillation fraction, approximately 90% PAH
In the Elizabeth River old abandoned wood-treatment facilities are a source for PAH via contaminated sediments

Antibody-based Chemical Sensor Development at VIMS
Current technology focuses on physicalCurrent technology focuses on physicalconditions and inorganic chemicals
What about PAH? Can we make an oil spill detector?
There is a need for “real-time” analysisThere is a need for “real-time” analysisof toxic chemicals in the environmentWhat about PAH? Can we make an oil spill detector?

Compensatory Mitigation Plan for Port Expansion at Craney Island
• Environmental Impacts
• Filling 522 acres open water and submerged bottom habitat
• Loss of fisheries habitat
• Loss of benthic habitat
• Compensatory actions.
• Toxic Sediment Remediation: Dredging to remove highest concentrations and sand caps to isolate remaining contaminants
• Wetland Restoration with • Wetland Restoration with fisheries habitat benefits: Excavate disturbed upland areas to create salt marsh habitat
• Restore previously disturbed tidal wetlands
• Oyster Reef/Clam Ground Restoration
