Groundwater Science, 2E, covers groundwater's role in the hydrologic cycle and in water supply, contamination, and construction issues. It is a valuable resource for students and instructors in the geosciences (with focuses in hydrology, hydrogeology, and environmental science), and as a reference work for professional researchers. This interdisciplinary text weaves important methods and applications from the disciplines of physics, chemistry, mathematics, geology, biology, and environmental science, introducing you to the mathematical modeling and contaminant flow of groundwater. New to the Second Edition:. New chapter on subsurface heat flow and geothermal systems. Expanded content on well construction and design, surface water hydrology, groundwater/ surface water interaction, slug tests, pumping tests, and mounding analysis.. Updated discussions of groundwater modeling, calibration, parameter estimation, and uncertainty. Free software tools for slug test analysis, pumping test analysis, and aquifer modeling. Lists of key terms and chapter contents at the start of each chapter. Expanded end-of-chapter problems, including more conceptual questions. Two-color figures. Homework problems at the end of each chapter and worked examples throughout. Companion website with videos of field exploration and contaminant migration experiments, PDF files of USGS reports, and data files for homework problems. PowerPoint slides and solution manual for adopting faculty.

This report reviews the available information on the use, environmental fate, and toxicity of spent lead shot and lost lead fishing weights. The report begins with a summary of information on the production, import, and use of lead shot and fishing sinkers in Canada. It then discusses the fate of these products in the environment, including chemical transformation of metallic lead in the environment, lead concentrations in soils and biota, and factors affecting the environmental mobility of lead compounds. The next section assesses the toxicity of lead shot and sinkers to waterfowl and non-waterfowl species, effects of lead shot ingestion in cattle, and human health concerns about hunting with lead shot. The report ends with a discussion of options for managing the negative impacts of those products, including using alternatives to lead, restricting use of lead shot, and alternative fishing sinker products.

Most reported incidents of soil contamination include an array of heavy metals species rather than a single ion. The various interactions in these multicomponent or multiple-ion systems significantly impact the fate and transport of heavy metals, and competition for sorption sites on soil matrix surfaces is a common phenomenon. Because of this, con
