This book was released on 1997 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods commonly used to delineate protection zones for water-supply wells are often not directly applicable for springs. This investigation focuses on the use of hydrogeologic mapping methods to identify physical and hydrologic features that control ground-water flow to springs to aid in delineating springhead protection zones. Two public-supply springs were selected as study sites to represent diversegeologic settings. One spring discharges from fractured dolomite and one from fractures siltstone, sandstone, and shale. Hydrogeologic mapping techniques, as applied in this study, are methods for mapping geologic or hydrologic features or geophysical/geochemical signatures of subsurface features. These data are often supplemented with information from subsurface investigations to aid in extrapolating surface results to aquifer depths. In this investigation, geologic mapping, fracture-trace analysis, topographic analysis, catchment area estimation, geochemical characterization, elemental isotope studies, and a tracer study were used to locate and describe potential ground-water flow boundaries and pathways and develop conceptual models for site hydrogeology. Results were integrated to estimate the zones of contribution to each spring and evaluated for use in the delineation of potential protection zones. Data from borings and hydraulic tests supported this characterization by providing direct and indirect information regarding susurface lithology and hydraulic parameters. In these case studies, results of hydrogeologic mapping allowed development of the conceptual model for site hydrology and evaluation of potential ground-water flow controls. Although definitive ground-water flow boundaries suitable for delineation of practicable protection zones could not be identified at either site, these techniques provided sufficient information to support an initial evaluation of potential protection zones. These results would also serve as a strong basis for additional investigations if more detailed or reliable delineations were warrented.

This book was released on 2006-09 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Environmental Protection Agency has recommended that states develop Pesticide Management Plans for four agricultural chemicals - alachlor, atrazine, metolachlor, and simazine - used in Utah as herbicides in the production of corn and sorghum, and to control weeds and undesired vegetation (such as along right-of-ways or utility substations). This report and accompanying maps are intended to be used as part of these Pesticide Management Plans to provide local, state, and federal government agencies and agricultural pesticide users with a base of information concerning sensitivity and vulnerability of ground water in the basin-fill aquifer (bedrock is not evaluated) to agricultural pesticides in the central Virgin River basin, Washington and Iron Counties, Utah. We used existing data to produce pesticide sensitivity and vulnerability maps by applying an attribute ranking system specifically tailored to the western United States using Geographic Information System analysis methods. 24 pages + 2 plates

Book excerpt: Geologists and geographers study how to develop how and where karst develops and how sinkholes form, but engineers must use this information to develop karst terrane. Over the past ten years, these multidisciplinary conferences on the applied aspects of karst hydrogeology and engineering have been successful in bringing together engineers, geologists, other scientists and government regulators who must safely establish human infrastructure on karst terrane whilst protecting the environment. The essences of these conferences has always been communciation between geologists and engineers with an emplasis on practical applications and case studies. This text contains the proceedings of the fifth conference on karst geohazards. It presents 65 papers that cover topics such as: groundwater contamination through sinkholes and the karst surface; stormwater drainage and flooding problems; and foundation considerations and improvements in karst.
