This book was released on 2013-12-17 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: The region of southeastern Massachusetts where the Towns of Plymouth, Carver, Kingston and Duxbury are located is known for its abundant water resources, its cranberry agriculture, and its unique ecosystems. Rapid population growth in this region, however, has resulted in increased competition among agricultural, commercial, ecological, and residential demands for water resources. Continued population growth has created the potential for increased groundwater withdrawals that could deplete streamflow and lower surface-water levels in streams, ponds, and wetlands and increase the loading of nonpoint-source septic contamination. These potential effects may contribute to habitat destruction, degradation of water quality, and loss of wetlands. The unconfined aquifer that underlies this region is composed mostly of glacially deposited sediments ranging in size from clay to boulders and is the second largest aquifer system in Massachusetts (Hansen and Lapham, 1992). It ranges in thickness from less than 20 to more than 200 ft, and contains more than 500 billion gallons of freshwater (Williams and Tasker, 1974). Groundwater discharge from the aquifer supports numerous kettle ponds and coastal streams (fig. 1). The aquifer was designated as a Sole Source Aquifer by the U.S. Environmental Protection Agency, recognizing that groundwater is a vital source of drinking water for many of the communities in the area. The population in this region has nearly tripled in the past 30 years; as a result, nearly 40 percent of agricultural lands in the region have been lost to development (Woods Hole Research Center, 2007). Over the next 20 years, the overall population of southeastern Massachusetts is projected to increase by more than 200,000, making this part of southeastern Massachusetts the fastest growing region in the State (The Nature Conservancy, 2002). Large increases in population and the conversion of open space to residential development creates concerns for potential effects on the quality and quantity of the region's water supply. Historically, the Plymouth-Carver area has been one of the most important centers of cranberry production in the United States. Cranberries produced in this region account for most of the Massachusetts harvests, and in 2001 were about one-third of the Nation's harvest (New England Agricultural Statistics Service, 2002). In recent years, a variety of economic factors, including out-of-state competition and declining cranberry prices, has led some cranberry growers to convert upland portions of their land holdings to residential development (Flint, 2002).The Nature Conservancy has recognized this area as one of the most significant ecosystems in the northeastern United States. The region contains unique ecosystems such as the Plymouth Pinelands, an approximately 30-mi2 area in the northeastern portion of the region, a large state forest (Myles Standish State Forest), and two State-designated Areas of Critical Environmental Concern (Ellisville Harbor and the Herring River Watershed) (fig. 1). Current and predicted growth in population and residential development and the reliance in this area on groundwater for water supply created the need for a reexamination of the water resources of the Plymouth-Carver-Kingston-Duxbury (PCKD) aquifer system. The U.S. Geological Survey (USGS), in cooperation with the Massachusetts Department of Environmental Protection, has conducted previous hydrologic studies of the aquifer system, including hydrologic assessments of aquifer yield and water quality (Williams and Tasker, 1974; Persky, 1993) and a regional modeling study (Hansen and Lapham, 1992). Advances in computing capabilities, numerical groundwater-flow models, and geographic information system (GIS) tools developed since the previous studies were conducted have allowed for the development of a more sophisticated groundwater-flow model that builds upon those earlier efforts.

Download or read book Natural Groundwater Flow written by Wouter Zijl and published by CRC Press. This book was released on 1993-02-03 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural Groundwater Flow is an important volume focused on providing a complete description of groundwater flow velocity field and the velocity oriented approach for conducting numerical simulations and other applications. The book presents background information regarding the causes leading to spatial variations of the water table, related concepts of phreatic and specific storage, artificial flow, and flow driven by differences in groundwater density. Block-scale permeability is discussed in detail, and numerical applications using the Galerkin finite element method and pre-modeling techniques for obtaining data required for numerical modeling are examined. The book also presents never-before-published information regarding the theoretical justification and elucidation of hydrological systems analysis to analyze the effects of different spatio-temporal scales. Natural Groundwater Flow is an important reference for environmental physicists, hydrogeologists, civil engineers, mathematical geologists, and petroleum reservoir engineers.
Download or read book Groundwater Management in El Paso Texas written by William Hutchuson and published by Universal-Publishers. This book was released on 2006-06 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundwater represents an important supply source for municipal and irrigation uses in Far West Texas. The City of El Paso receives about 50 percent of its municipal water supply from surface water and 50 percent from local groundwater. Groundwater pumping in El Paso is from the Hueco Bolson and the Mesilla Bolson. Historic groundwater pumping in the Texas portion of the Mesilla Bolson has not resulted in significant changes in groundwater levels or groundwater quality in existing wells. Historic pumping in the Hueco Bolson has resulted in lowered groundwater levels and brackish groundwater intrusion. The groundwater level declines have resulted in the intrusion of brackish groundwater into areas that historically pumped fresh groundwater. A 1979 assessment concluded that El Paso would deplete fresh groundwater in the Hueco Bolson by 2030 if groundwater pumping continued to increase. Partly as a result of the 1979 assessment, El Paso reduced its groundwater pumping from the Hueco Bolson by increasing surface water diversions from the Rio Grande, increasing conservation efforts, and increasing reclaimed water use. As a result, groundwater levels in many parts of the Hueco Bolson have stabilized. Brackish groundwater intrusion remains an issue, and is being addressed with a brackish groundwater desalination plant, currently under construction. The new wells and existing wells that will supply this desalination plant will also assist in the management of brackish groundwater intrusion by intercepting the brackish groundwater before it can flow towards existing fresh groundwater wells. The 2006 Far West Texas Regional Water Plan contemplates a groundwater transfer project to meet increasing demands in El Paso County beginning about 2030, mostly from the Dell City area in Hudspeth County, Texas. Groundwater management in the Dell City area is governed by a groundwater conservation district that has established limits on groundwater pumping based on existing and historic uses. Groundwater pumping for irrigation began in the Dell City area in 1948, and groundwater levels have been essentially stable for since the 1980s. Future planning for a groundwater transfer project will require a detailed understanding of the hydrogeology of the groundwater in the Dell City area.
Download or read book Groundwater Recharge and Flow written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2020-01-17 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water of appropriate quantity and quality is essential for drinking, sanitation, and food, energy, and industrial production for any society and is derived for most needs from surface- or groundwater sources. Studies suggest that groundwater use in irrigation globally is increasing in total volume as well as a percentage of all water used for irrigation, with the demand for groundwater resources increasing as available primary surface water supplies are depleted. Particularly in arid regions, groundwater may be the most accessible water supply for any purpose, leaving groundwater withdrawals concentrated in areas that are already experiencing water stress. Even in the presence of direct ground observations and measurements of the water table, quantitative evaluation of groundwater storage, flow, or recharge at different scales requires remotely sensed data and observations applied to groundwater models. Resolving the interaction of groundwater storage, flow, and recharge at a scale at which basins are managed requires remotely sensed data and proxy data. In June 2019, the Water Science and Technology Board of the National Academies of Sciences, Engineering, and Medicine convened a workshop to identify scientific and technological research frontiers in monitoring and modeling groundwater recharge and flow in various regions of the world. The goals of the workshop were to assess regional freshwater budgets under major use scenarios, including agriculture, industry, and municipal; examine state of the art research frontiers in characterizing groundwater aquifers, including residence time, quantity, flow, depletion, and recharge, using remotely sensed observations and proxy data; discuss groundwater model uncertainties and methods for mitigating them using sparse ground observations or data and other approaches; and consider our ability to detect which water management strategies that affect groundwater flow and recharge are being used and any changes in their use over time. This publication summarizes workshop presentations and plenary discussions.
