The objective of this cooperative research project is to examine the transport and fate of nitrate and pathogens at a dairy lagoon water application site and assess the performance of comprehensive nutrient management plans (CNMPs) to protect groundwater resources.
Approach: A CNMP field study will be initiated at a local dairy farm in San Jacinto, CA. This site will be instrumented to monitor and quantify the transport and fate of nitrate and pathogens. Complementary laboratory and numerical modeling studies will be conducted to improve our understanding of basic transport processes, to predict the transport behavior at other locations, and to address potential weaknesses in the land application design and operation processes.
