This lab manual features a hands-on approach to learning about the physical and chemical processes that govern groundwater flow and contaminant movement in the subsurface. It will aid users in developing a deeper understanding and appreciation for the science and art of hydrogeology. Twenty-one lab exercises provide practical material that explore regional aquifer studies, slug tests, and the use of tracers to determine aquifer and contaminant parameters and modeling retardation, biodegradation, and aquifer heterogeneity, and much more. For individuals interested in the study of hydrogeology.
