Research just published in Nature Communications by HAS Assistant Professor Laura Condon shows that even under modest climate warming scenarios, loss of groundwater may accelerate drying trends in the eastern United States. This new first-of-its-kind study simulates how water moves in the subsurface, particularly lateral movement, and connects with the land surface.
Condon used a large-scale computer simulation to demonstrate how groundwater will respond to persistent warming. Results show the eastern U.S. becoming much more sensitive to a lowering of the water table with the depletion of grou... Read More

Congratulations to HAS Assistant Professor Bo Guo whose ongoing research on PFAS in groundwater, Chemicals in Soils are 'Ticking Time Bomb,' was reported in a news article by UANews.org, on February 11.
A growing health crisis fueled by synthetic chemicals known as per- and polyfuoroalkyl substances, or PFAS, in groundwater has garnered much attention in the past few years. To understand how the chemicals migrate through the soil between the land surface and groundwater (vadose zone), Guo and his collaborators developed a novel mathematical model to simulate the different complex processes tha...
