Air sparging is pushing large amounts of air through the water and vaporizing gasoline hydrocarbons. Sparging also oxygenates the water and sediment, promoting natural degradation by increasing the number of microorganisms that break down hydrocarbons. Thermal scanning of the soil for hot spots has been completed. Work continues to execute a water sampling plan to determine the extent of possible exposure to natural resources in Whatcom Creek and Bellingham Bay. Shoreline and stream assessment and sampling continue to determine the extent of contamination and erosion potential of the shoreline.
All fires are extinguished.
Gasoline is continuing to seep from a small spot on the hillside, near the water treatment plant. It is being contained using absorbent pads, as well as booms. Skimmer operations continue. Water sampling continues at the seep site as well. For safety reasons and in an effort to give nature a chance to repair, the public is advised to stay away from Whatcom Falls Park.
