 Newsroom Detail


Portland, OR—• DEQ and EPA emergency response crews are continuing their work in the Pearl District, downtown Portland, and other areas along the south bank of the Willamette River. Seven teams are looking for and removing asbestos-containing debris released from the May 14 North River Street warehouse fire.

• Results from the five stationary air sampling units continue to show either ‘no detection' of asbestos fibers or levels that are well below action levels. This means there are no special precautions people need to take as they go about their daily lives.

• In addition to the stationary air monitors, some field crew members are wearing portable, personal air samplers to measure asbestos concentrations in their breathing zone as they perform their debris reconnaissance and recovery duties. These personal devices are yielding data comparable to the stationary air sampling devices of either ‘no detections' of asbestos fibers or levels that are below action levels.

• Preliminary air sampling results and a map of the debris search and cleanup area are available at the following link: We will continue to provide air sampling results as they become available.

• Crews continue misting the warehouse debris pile with water. The misting efforts will continue around the clock to prevent further release of asbestos fibers.

• We are not aware of any instream or downstream asbestos contamination in the Willamette River resulting from the warehouse fire. Any asbestos deposited in the river from the fire would not pose a health impact.

• Community outreach efforts also continue, with teams walking affected neighborhoods and supplying safety tips and information about the cleanup.

Public Safety Tips:

• Do not touch, pick up, move or vacuum any debris that may have come from the fire. Asbestos-containing debris will look like ash or paper, and crumbles into fibers easily.

• If you find any of this debris, do not touch it and please call 503-229-6488. Leave a message with: your name and phone number, address or location where you saw the debris, and what the debris looks like. We will contact you with more information.
