After three years working as a research technician at the University of Nebraska I have returned as a graduate student to complete a Master's degree in Natural Resources. While spending a summer in Colorado before my sophomore year at UNL, I became fascinated by the beautiful outdoor surroundings. My curiosity to learn about the subtleties lying within these landscapes motivated me to pursue a career in the environmental field. I declared a major in Environmental Studies and received my undergraduate degree in May of 2011. After graduation I worked as a research technician in two UNL laboratories specializing in aquatic ecology and crop physiology, which I've highlighted further in my CV. These positions allowed me to gain valuable lab, field, and technical writing experience. I am now applying this knowledge to my Master's research as I work with Dr. Dan Snow to understand contaminate transport and transformation in Hastings, NE. I will leverage the skills I build as I pursue a career in environmental consulting, specializing in water quality. Ultimately, I want to become a project manager, supervising other consultants focusing on these issues.

Measurement of accumulated nitrate in the vadose is critical for predicting whether changing surface activities are impacting nitrate leaching to groundwater beneath agricultural fields. This research investigated the occurrence and movement of nitrate over time using deep vadose zone soil cores collected from the Hastings, NE Well Head Protection Area (WHPA). Profiles were generated from cores collected from urban and irrigated farmland and compared to a previous study done at the same locations. Sampling previously collected sites allow for direct comparisons of current and historical nitrate-N profiles, potential movement, and can provide a method for evaluating effects of changing land use at the surface. Cumulative nitrate in the top 65 ft for urban irrigated lawns, pivot irrigated farmland, and gravity irrigated farmland had an average of 320, 540, and 700 total lbs-N/acre respectively. In farmland where irrigation changed from gravity to pivot application there was an average reduction of 170 lbs-N/acre in the top 55 ft of the profile over a five-year time span. This observation supports the use of sprinkler irrigation for more uniform water application, reducing potential leaching at the head and tail rows of gravity irrigated fields. While future studies are still needed, the importance of vadose zone monitoring in evaluating and protecting groundwater is beneficial in determining connections between surface activities and the underlying groundwater.
