Chester Creek Water Quality Monitoring with Biology 373
Professor Frank von Hippel received a minigrant in spring 2012 to re-engage Biology 373 students with the Russian Jack Community Council and the Anchorage Waterways Council in a project focused on the reassessment of water and habitat quality. Students were involved with replicating analyses conducted by earlier classes (2001-2005 and 2009) for before and after restoration comparisons; assisting with new analyses using stable isotope techniques to test for the presence of marine-derived nutrients in the system; and making recommendations for future restoration work with a damaged portion of the creek. Prior studies found there were indications of "potential human health impacts and reduced species richness due to degradation of the watershed.
von Hippel commented on the demands of engaged learning with real life projects. Data quality is a concern in that student data has to be as good as faculty data if it is going to be used by the community for policy work or for publication; it requires considerable faculty time and oversight. He or a graduate student collect their own water chemistry data for comparison purposes and look at student data right away to redo what seems out of the realm of possible or probable, and for the invertebrate data, they are alongside students as they record data. They use occasions to teach critical thinking in the moment by looking at what students have done and asking, "Does this make sense?" Most of the data issues experienced in the early years were solved by switching to a simpler chemistry kit. A CCEL grant made it possible in the beginning to pay for supplies and a student helper, and the minigrants still assist with the costs of the monitoring kits. Long-term commitment to this project has made it possible for students to see the before and after impacts of the environmental intervention with the Westchester Lagoon and to deepen the relationship with the community partners.
