## Abstract

Fractures in underground rock formations significantly influence how water, solutes, and colloids move through the subsurface. These processes are crucial to addressing real-world challenges such as ensuring drinking water quality; providing sufficient water quantity for consumption, agriculture, and industrial purposes; and managing geothermal energy, carbon dioxide, hydrogen, and natural gas storage resources. However, the complexity of fractured rock systems makes them difficult to study and represent with mathematical models. This project will use multi-scale advanced imaging and geophysical monitoring technology to "see through" rocks and quantify how fluids and colloids move through fractures. These rich datasets will enable the development of simpler, more efficient models for predicting flow and transport in fractured rocks and thus enable scientists and engineers to better manage subsurface water resources. In addition to advancing science, this project prioritizes education and outreach. A major objective of the educational plan is improving STEM education in rural Wisconsin. Through a partnership with a nature-based learning center, hydrology modules will be developed for middle school summer camps, high school field trips, and community visitor events. Collectively, the education plan objectives of this project are anticipated to improve hydrogeology education across different educational levels, enhance participation of individuals from rural communities in centr
