  • Effects of global climate change on groundwater resources

Research Impacts

My current research focuses on the protection and sustainable use of groundwater resources. Globally, about 1.7 billion people rely on groundwater as the primary source of drinking water. Within the United States, groundwater is the main water source for about 40% of the population. Both the quality and quantity of groundwater have profound implications for public health and well being.

The research projects that I am currently working on can be divided into three research themes. In the first research theme, I seek the understanding and prediction of the transport of contaminants such as bacteria and nanoparticles within the groundwater systems. Policy makers, scientists, engineers and concerned citizens can use the information to develop management, protection and remediation plans. The second theme of my research focuses on the development of novel and inexpensive geosorbents (e.g., modified zeolite) to remove contaminants from water. Finally, I am studying how global climate change could potentially influence groundwater resources.
