Book Description
A study of groundwater flow, quality, and mixing in relation to Wind Cave National Park in western South Dakota was conducted during 2007-11 by the U.S. Geological Survey in cooperation with the National Park Service because of water-quality concerns and to determine possible sources of groundwater contamination in the Wind Cave National Park area. A large area surrounding Wind Cave National Park was included in this study because to understand groundwater in the park, a general understanding of groundwater in the surrounding southern Black Hills is necessary. Three aquifers are of particular importance for this purpose: the Minnelusa, Madison, and Precambrian aquifers. Multivariate methods applied to hydrochemical data, consisting of principal component analysis (PCA), cluster analysis, and an end-member mixing model, were applied to characterize groundwater flow and mixing. This provided a way to assess characteristics important for groundwater quality, including the differentiation of hydrogeologic domains within the study area, sources of groundwater to these domains, and groundwater mixing within these domains. Groundwater and surface-water samples collected for this study were analyzed for common ions (calcium, magnesium, sodium, bicarbonate, chloride, silica, and sulfate), arsenic, stable isotopes of oxygen and hydrogen, specific conductance, and pH. These 12 variables were used in all multivariate methods. A total of 100 samples were collected from 60 sites from 2007 to 2010 and included stream sinks, cave drip, cave water bodies, springs, and wells.

Book Description
This book illustrates the diversity of hypogene speleogenetic processes and void-conduit patterns depending on variations of the geological environments by presenting regional and cave-specific case studies. The cases include both well-known and newly recognized hypogene karst regions and caves of the world. They all focus on geological, hydrogeological, geodynamical and evolutionary contexts of hypogene speleogenesis. The last decade has witnessed the boost in recognition of the possibility, global occurrence, and practical importance of hypogene karstification (speleogenesis), i.e. the development of solutional porosity and permeability by upwelling flow, independent of recharge from the overlying or immediately adjacent surface. Hypogene karst has been identified and documented in many regions where it was previously overlooked or misinterpreted. The book enriches the basis for generalization and categorization of hypogene karst and thus improves our ability to adequately model hypogene karstification and predict related porosity and permeability. It is a book which benefits every researcher, student, and practitioner dealing with karst.

Book Description
"Knowledge and understanding of cave and karst systems have evolved dramatically since the creation of the Geological Society of America in 1888. This book, which came out of a session during GSA's 2013 Annual Meeting, highlights the changes in the study and application of cave and karst systems since GSA's origin, while looking ahead to future advancements"--

Book Description
In this 46-page report, we characterized the deep aquifer system and its connections to the overlying aquifers in the area of the Hurricane fault in Washington County by examining well logs, creating regional potentiometric-surface maps, compiling groundwater quality data, conducting gravity surveys, examining remote sensing data for surface lineaments, and determining areas for potential monitoring wells. Results of the study were: (1) R and C aquifer groundwater depths are > 500 feet in the I-15 corridor area, (2) a groundwater divide likely exists south of the Utah-Arizona state line, (3) groundwater flow follows open fracture systems, (4) fracture conductivity is highest near the fault, (5) dissolution of evaporites increase groundwater TDS, and (6) a well should be drilled into the Hurricane fault near Pintura.

Book Description
Methods for the Determination of Metals in Environmental Samples presents a detailed description of 13 analytical methods covering 35 analytes that may be present in a variety of sample types. The methods involve a wide range of analytical instrumentation including inductively coupled plasma (ICP)/atomic emission spectroscopy (AES), ICP/mass spectroscopy (MS), atomic absorption (AA) spectroscopy, ion chromatography (IC), and high performance liquid chromatography (HPLC). The application of these techniques to such a diverse group of sample types is a unique feature of this book. Sample types include waters ranging from drinking water to marine water, in addition to industrial and municipal wastewater, groundwater, and landfill leachate. The book also includes methods that will accommodate biological tissues, sediments, and soils. Methods in this book can be used in several regulatory programs because of their applicability to many sample types. For example, ICP/AES, ICP/MS, and AA methods can be used in drinking water and permit programs. Methods applicable to marine and estuarine waters can be used for the EPA's National Estuary Program. Terminology is consistent throughout the book, an important feature especially for the quality control sections where standardized terminology is not yet available. Methods for the Determination of Metals in Environmental Samples is an indispensable methods guide for all environmetal labs, wastewater labs, drinking water labs, lab managers, consultants, and groundwater engineers.
