Center for Urban Waters research team evaluates constructed hyporheic zone in stream restoration
 PSI’s parent organization the Center for Urban Waters at UW Tacoma is collaborating with Seattle Public Utilities (SPU) to evaluate water quality improvements in a constructed hyporheic zone in Seattle. Project PI: Ed Kolodziej.

Several scientists at the Puget Sound Institute and the University of Washington Center for Urban Waters are developing new techniques for analyzing the chemical composition of stormwater. They recently published a paper co-authored with collaborators from NOAA and the Washington Stormwater Center outlining some of these techniques in the journal Environmental Science. The authors used “time-of-flight” mass spectrometry to identify novel compounds in runoff and fish tissues.
