Assistant Professor of Environmental Science and Geology at Buena Vista University, Benjamin Maas, will present his seminar on Friday, November 22.

 

Conducting place-based research at a small liberal arts university is not only possible but can offer critical support to students (i.e. place based learning) and the community (management decisions). The BVU campus is located on the shores of Storm Lake, providing ample research opportunities. Over the years, the waters of Storm Lake and of the watershed have been and continue to be assessed, allowing students to gain knowledge on water quality issues and take ownership of content.

The first portion of this presentation will highlight some of the findings from the ongoing water quality research. In short, data indicate that creeks flowing into Storm Lake have elevated nitrate as nitrogen concentrations and at times elevated sediment loads, the latter being caused by precipitation events. The lake also has elevated and increasing chloride concentrations. The City of Storm lake has used data from research projects to help guide ongoing stormwater projects to improve the lake’s water quality and the city’s flood management plan.

The second portion will focus on another example of research that can be completed at a small liberal arts university: remote sensing of agriculture and karst. Karst landscapes in the Midwest can be locally common and complicate agricultural activities. Complications include thin and rocky soil, nutrient and fertilizer management concerns, and effects on groundwater resources. Best Management Practices for agricultural activities have historically been written for surface water concerns, with minimal consideration for the interconnection between surface and groundwater in karst areas.

Presented here will be a description of concerns associated with higher livestock concentrations in karst landscapes and present approaches and regulations to minimize agriculture’s environmental impact in karstic areas. These regulations will aid in protecting groundwater and soil reserves.
