Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the geology, hydrogeology, and water quality/geochemistry of karst systems in geologically young terrain, using the state of Florida as an example. Also discussed are sinkhole-development models; sinkhole risk; eogenetic karst features developed in rocks as young as 125,000 years and as old as 65 million years; and karst landscapes of Florida, including regional geology and geomorphology with important examples of karst features, such as springs, sinkholes, caves, and other karst landforms. The eogenetic karst of Florida is largely covered and this book extensively discusses the interactions of karst processes with sand- and clay-rich cover materials.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Uncertainty around the relationship between underground injection-controlled wells and groundwater quality has spurred conversations around the potential environmental and societal impacts oil extraction may have on potable water, soil and plant life. The nature of the chemicals and disposal processes of water used within underground injection-controlled, coupled with advancements in oil and gas technology, have called for a closer look at how fracturing and flowback fluid may be affecting the environment. In this dissertation, a spatial evaluation of the groundwater quality constitutes related to salinity and underground injection-controlled well operations was performed on the Permian Basin extents of the Ogallala aquifer during the sample years 2004 to 2016. The foundation for this research was an assessment of the spatial patterns of freely available in situ data on groundwater quality provided by the Texas Water Development Board and underground injection-controlled operations by the Texas Railroad Commission. The goal of this research is to provide a regional assessment of the interactions between dynamically changing underground injection-controlled operations and salinity groundwater quality constitutes. Groundwater quality constitute datasets chosen for analysis underwent exploratory data analysis, Empirical Bayesian Kriging interpolation, and non-parametric Mann-Whitney-Wilcoxon statistical testing to measure data variation and significance of change across the study area and time. Relationships of underground injection-controlled well operations to salinity groundwater quality constitutes were evaluated using visual analysis and spatially constrained multivariate clustering. The analysis also explores the relationship of individual operational parameters, such as maximum fluid volume and pressure, to groundwater quality constitutes through cluster and outlier analysis and non-parametric Mann-Whitney-Wilcoxon testing to measure the magnitude of influence. To expand beyond the use of in situ data, an investigation of the application of salinity, vegetation, and moisture indices derived from Landsat imagery to explain regional variance in Total Dissolved Solids, an overall water quality indicator, was performed employing regression analysis. The research presented in this dissertation reveals a potential link between UIC operations disposal wells and increased salinity concentrations within the groundwater. Utilizing freely available secondary datasets, provided by the state of Texas, an assessment salinity focused groundwater quality constitutes and their relationship to UIC operations was explored. Results indicate that the southern region, comprised mainly of disposal well activity has seen rises in salinity groundwater constitute concentrations across the study period. Providing a regional and complete view at salinity groundwater quality and UIC operations, the research in this dissertation serves as a guideline for developing procedures on the environmental assessment of salinity around UIC operations and as a tool for operators to evaluate potential risks with new and existing development areas. The methods and techniques presented in this study are not specific to the region. Replicability to other basins with underground injection-controlled operations can be used to aide other researchers in determining localized impacts.

This book was released on 2016 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents the efforts and analyses conducted for the Applied Studies and Technology (AS&T) Ancillary Work Plan (AWP) project titled Evaluation of Pre- and Post- Redevelopment Groundwater Sample Laboratory Analyses from Selected LM Groundwater Monitoring Wells. This effort entailed compiling an inventory of nearly 500 previous well redevelopment events at 16 U.S. Department of Energy Office of Legacy Management (LM) sites, searching the literature for impacts of well redevelopment on groundwater sample quality, and—the focus of this report—evaluating the impacts of well redevelopment on field measurements and sample analytical results. Study Catalyst Monitoring well redevelopment, the surging or high-volume pumping of a well to loosen and remove accumulated sediment and biological build-up from a well, is considered an element of monitoring well maintenance that is implemented periodically during the lifetime of the well to mitigate its gradual deterioration. Well redevelopment has been conducted fairly routinely at a few LM sites in the western United States (e.g., the Grand Junction office site and the Gunnison processing site in Colorado), but at most other sites in this region it is not a routine practice. Also, until recently (2014–2015), there had been no specific criteria for implementing well redevelopment, and documentation of redevelopment events has been inconsistent. A catalyst for this evaluation was the self-identification of these inconsistencies by the Legacy Management Support contractor. As a result, in early 2015 Environmental Monitoring Operations (EMO) staff began collecting and documenting additional field measurements during well redevelopment events. In late 2015, AS&T staff undertook an independent internal evaluation of EMO's well redevelopment records and corresponding pre- and post-well-redevelopment groundwater analytical results. Study Findings Although literature discussions parallel the prevailing industry-wide assumption that well redevelopment is necessary to increase production or to extend the life of a well, no data in the literature indicate that redevelopment affects chemical signatures in monitoring wells. The comprehensive evaluation undertaken for this study also yielded no evidence that redevelopment has any quantifiable or predictable effect on groundwater sample quality. Both short-term and long-term changes in groundwater chemistry were assessed relative to preceding and subsequent well redevelopment events. Although short-term changes in specific conductance or contaminant concentrations likely attributable to well redevelopment were found at some sites, these cases were limited to a small subset of wells in which chemical stratification had been observed. Redevelopment causes mixing of the well water, resulting in short-term impacts, but not in a consistent direction. Long-term groundwater concentration trends of uranium, the primary contaminant of concern at most LM Uranium Mill Tailings Radiation Control Act (UMTRCA) sites, were evaluated for all 16 sites addressed in this study. Based on the data evaluated, there are no apparent impacts of well redevelopment on uranium trends. In most cases where deviations in trends were found, these could be attributed to water level fluctuations or other factors. A few exceptions were found where spikes or marked decreases in uranium concentrations could potentially be related to the preceding well redevelopment, but apparent impacts were neither predictable nor quantifiable. Summary and Recommendations A catalyst for this project was a concern that there was a need for strict criteria for a program-wide approach to well redevelopment at LM sites. There was also an implicit question as to whether well redevelopment was a necessary practice that was being overlooked at some sites. The primary objective of this study was to determine if there are significant differences in laboratory analytical results between pre- and post-rede...
