Science on Tap is a science lecture series where you can sit back, enjoy a pint, and laugh while you learn. Listen to experts talk about the science in your neighborhood and around the world. You don’t have to be a science geek to have fun—all you need is a thirst for knowledge!

The Portland Harbor Superfund Site is a stretch of the Willamette River north of downtown Portland where sediment was contaminated due to industrial activities over the past 100 years. Cleanup efforts are complex and involve numerous government and private organizations, and this talk will focus mainly on one aspect of the work: Oregon Department of Environmental Quality’s efforts to clean up properties that can contribute pollutants to the river. Onshore contaminants from still operating or long-shuttered industrial businesses can make their way into the river, and the DEQ has been working since the 1980s to prevent contamination from getting into the water.

At this Science on Tap, Keith Johnson, DEQ Northwest Region Cleanup Manager, and Alex Liverman, DEQ Portland Harbor Stormwater Coordinator, will talk about the cleanup efforts, including specific site examples of eroding soil/banks, groundwater, and stormwater. Hear about collaboration with the Environmental Protection Agency to ensure that on-going land-based activities don’t pollute the river again after EPA’s cleanup, and how plans are moving forward to clean up the river sediment.
