Field Research Laboratory

This laboratory serves as the Groundwater Geochemistry and Remediation Research Group’s field-sample processing location. Our investigations include inorganic and organic samples of various scales such as water samples, cores, sediments, sludges, and various rock and mineral samples that may range from individual minerals to a tonne of rock. At this location and the adjacent loading dock, we can receive all samples and process them without introducing contaminants into the analytical laboratories. Additionally, within this laboratory, we have the capability to perform pre-analytical processing such as aqueous field measurements, milling and pressing for x-ray fluorescence/diffraction, or soil water removal from cores along with experimental areas to conduct weathering experiments in cold and ambient temperatures.
