Description

This work focuses on laboratory results completed July, 2016, as part of a Utah Department of Environmental Quality (UDEQ) funded project to develop methods for nitrogen transformation rate determinations. The objective of this portion of the project is to identify feasible laboratory-based methods which can be utilized to determine nitrogen transformation rates, representative of field determined rates, which can then be applied in water quality modeling. In order to evaluate this objective, rates determined from laboratory methods are compared to rates measured in-situ using benthic chambers and water quality model auto-calibration values, with the assumption that in-situ determination allows for true rates to be established. This poster will detail the laboratory-based methods used, results of each method, and comparisons to field-determined and model auto-calibration values. Recommendations of optimal laboratory methods based upon this comparison will also be provided.
