Clean up crews have worked around the clock to excavate and remove diesel-contaminated soils from the site of Thursday morning’s locomotive derailing on the Swinomish Indian Tribal Community Reservation near Anacortes, Washington.

Thus far, crews have removed over 1,200 cubic yards of soil. Responders have also pumped out 3,000 gallons of contaminated groundwater found while excavating the soil. Crews will install groundwater wells to monitor for any migration of diesel from the spill site.

As a precaution, incident commanders from the U.S. Environmental Protection Agency and the Washington Department of Ecology estimate that up to 2,000 total cubic yards of soil may be removed. BNSF is temporarily storing the contaminated soil until it can all be sent for disposal in a permitted landfill.

No spilled diesel has reached the shoreline, but the area remains boomed as a precaution. There are still no impacts to wildlife.
