SAN FRANCISCO - Response team members with the Cosco Busan Incident apply oil-lifting chemicals to oiled rocks in Berkeley Marina Nov. 21, 2007.
Three areas were surrounded by containment boom and used to test two chemicals. The third was a control area and was only sprayed with salt water.
Other responders used a boat to test the amount of oil at different depths in and around each area. The Unified Command will select the most environmentally friendly and most effective method to supplement ongoing response efforts.
