This compilation of papers presents an international survey of contemporary issues related to groundwater management, and the current and emerging technologies involved. Modeling and case studies are provided, as topics range from groundwater/surface interactions to contaminated site remediation, multiphase flow, transboundary groundwater issues, and bioremediation. Geographic information systems, wellhead protection, agricultural contamination, and aquifer storage and recovery are also addressed. Specific papers examine the quantification, characterization, and treatment options of landfill leachate; irrigation, geology, and wetlands in semi-arid regions; remediation of contaminated aquifers with reclaimed sewage water; minimum cost design of a funnel-and-gate system; lake and surficial aquifer interaction; and evaluation of induced infiltration in glacial drift aquifers.
