Short Description of your Research or Creative Project (700 characters or less)

The Arcata Wastewater Treatment Facility uses constructed wetlands to treat municipal wastewater. In this study, we examined how dissolved carbon and nitrogen were removed, degraded, and transformed within the Arcata Wastewater Treatment Facility over the course of a year. It was found that dissolved carbon was removed by the treatment system, and the biological activity transformed it into a form that had less impact on Humboldt Bay, while dissolved nitrogen was removed effectively, except in winter and spring months. Overall, the study provides a better understanding of the temporal variation of dissolved carbon and nitrogen in the constructed wetlands system, which will help the City of Arcata better manage the wastewater discharged to Humboldt Bay.
