The Coast Guard, state and local agencies as well as contracted environmental agencies continued the unified effort to cleanup and investigate Friday night's oil spill in the Delaware River. Limited traffic is being permitted to transit the security zone on a case by case bases. Protective barriers will be in place as needed to ensure the oiled areas around the vessel are not spread during the vessel's movement. Daily over-flights and boat crews will monitor the channel for further oil. The vessels will be cleaned after they transit the impacted area to limit the spread of the oil. An additional 170 workers will be added to the efforts bringing the total to 400 people involved in the clean up. Crews have recovered thousands of gallons of oil and oil water mixtures.
