Several people from the Bellingham, Portland, and Vancouver (WA) offices of Maul Foster and Alongi had a special seminar for SMoCS students today. The seminar used examples of cleanup sites the company has worked on near Portland. They showed examples of dredging and a sediment cap being placed. They showed examples of models used for decisions as to how deep a sand layer should be for a cap, what expected contaminant concentrations are on a site, and a TCE and degradates groundwater plume. They also showed an a strategy for cleaning up groundwater contamination with a permeable reactive barriers.
This presentation was a great supporting element to the Fate and Transport and SMoCS classes. Thanks to all who attended and presented!

Site Visit to the ESY Site
About 32 students went to the Port of Everett today to visit our site (the Everett Shipyard) for the SMoCS courses. We met representatives of the Port, who is responsible for the cleanup activities of the site. They presented background information about the Port, the site, and MTCA and then took us on a tour of the site. We saw the marine railway where boats were removed from the water and the areas where maintenance on the boats was conducted. The contaminated material from sand blasting was still present on site, which was interesting for the students to see. Our tour guides also showed up the new boat storage area, where all surface run-off is collected in underground tanks and sent to the municipal water treatment facility, essentially eliminating non-point source run-off from the site.

New SMoCS courses at Huxley
The new Science and Management of Contaminated Sites (SMoCS) courses started today. Almost 40 students from Environmental Sciences, Environmental Studies and Journalism are enrolled. The students are in for a great quarter as we learn about the Model Toxics Control Act (MTCA), which is the Washington State regulations through which some contaminated sites are cleaned up. We are focusing on the Everett Shipyard (ESY) site this quarter.` I'll have occasional posts about the course here.
