About the lab
|
The Hydrology and Geochemistry Research Lab, led by Dr. Hasenmueller, has a variety of research projects in both natural and impacted systems. Our research focuses on (1) identifying the origin and transport of contaminants in surface waters and groundwaters, (2) understanding spatial and temporal variations in hydrology and geochemistry to identify anthropogenic influences on water budgets, and (3) determining the influence of critical zone soil biogeochemistry on weathering processes. The lab combines a ground-truth approach with a broad array of advanced analytical tools to address issues of environmental concern. Thus, most of our studies involve field observations of water quality and flow dynamics coupled with lab-based analyses of tracers (i.e., stable isotopes, major ions, and trace elements). To learn more about specific projects in the lab and research opportunities, check out the Research tab.

July 2, 2015: Andrew and Emily catch a storm series at Deer Creek! They observed an increase in E. coli levels as the flood progressed, which is likely the result of combine sewer overflow discharge.
June 23, 2015: A large storm hits the St. Louis area causing flash flooding around the city. Graduate student Heather (with help from the rest of the lab) was able to capture a series of flood water samples at both her rural and urban spring sites. Heather found that her urban site, Blackburn Spring, lived up to its flashy reputation! The left and middle pictures below show Blackburn during low flow, while the right photo shows Blackburn during the June 23 flood event - the entire valley was filled with flood water! Flood response samples like these help Heather determine transport mechanisms of chloride from road salting.
