Geography, Geology and the Environment


Agriculture is known to be one of the leading causes of surface water pollution. Illinois and the Midwest in general experiences extensive agricultural activities due to availability of fertile lands. Nutrients such as nitrogen from agricultural activities are the principal source of nonpoint surface water pollution. The US Environmental Protection Agency (EPA) recommends use of saturated buffer zones (SBZ) for nutrient load reduction prior to water entry into streams (Mayer et al, 2006). Previous works illustrate how the SBZ is effective in nitrate load reduction (Jaynes and Isenhart, 2019a; McEachranet al (2020). This study focuses on using a 3D steady state heterogeneous numerical model to understand groundwater flow in the SBZ with T3 site as case study.
