For students in Rob Turner\u2019s Environmental Monitoring Practicum, it\u2019s just a matter of minutes between dipping water samples in the North Creek wetlands and testing their quality at a science lab in Commons Hall on the University of Washington Bothell campus. More than convenience, it connects fieldwork and analysis. <\/p>\n\n\n\n

\u201cThere are a lot of times where you just get the data without knowing how to collect it, so this class really helps you understand where it comes from, what\u2019s the proper technique to get it,\u201d said Nina Tran (Environmental Science \u201919). <\/p>\n\n\n\n

Several teams of Turner\u2019s students collected water for various tests. One team caught water as it flowed from storm drains through catch basins to the wetlands. Their samples would measure changes in dissolved oxygen, temperature, conductivity and turbidity (or water clarity) in the runoff system. Another team measured nitrates in bioswales \u2014 ditches with vegetation that buffer the wetlands. Others collected samples they would test for E.coli bacteria back in the lab. <\/p>\n\n\n\n

As interesting as the results may be, the main lesson is attention to the process, said Turner, a senior lecturer in the School of Interdisciplinary Arts and Sciences<\/a>. That includes careful record keeping, equipment calibration and sterilization of lab gear and sample bottles. <\/p>\n\n\n\n

\u201cYou have to be rigorous in your methods to make sure you don\u2019t mess up your samples and the quality of the data you generate,\u201d Turner said. <\/p>\n\n\n\n

Where the water flows<\/h2>\n\n\n\n

The 58-acre wetlands<\/a> along North Creek were restored in the late 1990s when establishing the 132-acre campus, which was once part of the Truly-Boone farm. A preserve for native plants and animals, the wetlands are a living laboratory for faculty and students at UW Bothell. <\/p>\n\n\n\n

On one sampling day in mid November, when a few yellow leaves hung in the branches and gnawed tree trunks showed where beavers had been busy, a group of students dubbed \u201cTeam Nitrate\u201d probed for samples in the bioswales. <\/p>\n\n\n\n

When rainwater flows, samples from different locations would indicate varying nitrogen levels, said Bee Elliott (Environmental Studies \u201920). After a dry spell, the bioswales were empty or held stagnant water. <\/p>\n\n\n\n

Guessing from the smell of the stagnant water, it would have a high nitrate level, said Allyn Rwamashongye (Environmental Science ’19).<\/p>\n\n\n\n

Jordan Fette (Environmental Science \u201919) said he had been \u201cmucking around in the wetlands\u201d for a few other classes and appreciated learning the techniques. \u201cYou get to go out there firsthand and use the equipment, use the sensors, see the changes and physically check it out,\u201d he said. <\/p>\n\n\n\n

On another day back in the lab, UW2-231, students put on white lab coats, goggles and purple nitrile powder-free exam gloves to process samples for E.coli. This requires filtering water samples, incubating portions in petri dishes and counting the growing E.coli bacteria. <\/p>\n\n\n\n

\u201cYou\u2019re involved in every step of the experiment, and you know all the variables that are going into it \u2014 and things that could go wrong,\u201d said Nicole Tim (Environmental Science \u201919). \u201cSomeone just in the lab, they don\u2019t necessarily know. If you get to see the whole continuum, I feel that\u2019s really beneficial.\u201d <\/p>\n\n\n\n

Robert Young (Environmental Science, \u201919) said he expects the real-world experience will help when he looks for a job in government or companies that study environmental impacts. <\/p>\n\n\n\n

E.coli, common to the gut of any warm-blooded animal, serve as a proxy measurement for all pathogenic organisms that might come from feces, Turner said. No one has to look, or step, far for a possible source. <\/p>\n\n\n\n

\u201cWe found pretty high E.coli counts, particularly within the roost zone for the crows,\u201d Turner said. \u201cThey do a lot pooping on campus and particularly in the wetlands.\u201d<\/p>\n\n\n\n
