Water is arguably the most critical and at-risk resource currently endangering the health of humans and ecosystems. The primary function of the Environmental Processes Laboratory is to improve scientific understanding of the processes controlling the cycling of a variety of waterborne chemicals and microorganisms in native and managed systems at a variety of scales (e.g. benchtop, field). Many of these laboratory-level analyses support broader computational efforts used in guiding management and remediation efforts. Equipment includes: Shimadzu GCMS (N20, N2, CH4 trace gas analysis), Picarro 5208 (N20, CH4, CO2, NH3, and H20 trace gas analysis), UV Vis (NO3 PO4, SO4), Scan Spectrophotometers (N03, TOC, DOC, COD), and a titration station.
