There is an essential resource constantly flowing beneath our feet: groundwater. Urban denizens may not think about it often, or at all, because they don’t rely on wells, “but it’s still there,” says hydrologist Claire Welty, and it’s critical to understanding the health of urban ecosystems. 

Welty is director of UMBC’s Center for Urban Environmental Research and Education (CUERE) and a professor of chemical, biochemical, and environmental engineering. Groundwater is just one piece of a complicated puzzle that she and her team will work to put together over the next five years. A $4.8 million Critical Zone Collaborative Network grant from the National Science Foundation will make the large-scale project possible. The grant will support researchers at UMBC and eight other institutions that are part of the UMBC-led Urban Critical Zone Cluster.

Welty’s team will explore Earth’s critical zone, which extends from the tops of trees to the base of weathered bedrock, in urban centers along the Eastern Seaboard. In particular, they’re interested in how natural, geological processes occurring below the Earth’s surface and human-driven processes interact. Human influences include road salt application, polluted stormwater runoff, and soil-disturbing construction. These factors can all significantly influence urban water quality, water chemistry, and weathering processes. 

Most Critical Zone grants are for work in more pristine wilderness areas, because the added effects of urban processes make the research more complicated. But, Welty says, “that’s the most interesting part.”
