Making the Invisible Visible: Olympia's Artesian Wells and Public Space Design
… today the majority of Olympia's free-flowing artesian wells are all but forgotten. Only a few of more than ninety-six historic wells have not been capped, diverted into the sewer or stormwater system, or permanently decommissioned. The neglect, loss, and deliberate destruction of Olympia's …

Living near permanent water in the upper Murray-Darling Basin Implications from the micromorphology of buried soils near artesian springs
Understanding links between landscape change and early peoples that lived along Eulo Ridge in the upper Murray Darling Basin, Australia are hampered by poor environmental data and chronological frameworks. To address such issues, steep sided gullies (arroyos), soil micromorphology and pedology, and …

The sorption of fluoride ion with special reference to fluoride removal from potable waters
… are obtained almost exclusively from the artesian wells of the Dakota Sandstone formation. In the district the dental lesions have found to be especially severe. </p><p> During the past two years the writer has assisted Professor G. A. Abbott, of the University, in making a comprehensive …

Groundwater management using a GIS case study : Uitenhage Subterranean Government Water Control Area
… Cape forms the centre of one of the biggest artesian groundwater basins in South Africa. The Table Mountain Group quartzitic sandstones are overlain by a thickness of postPalaeozoic sediments giving rise to artesian groundwater. The most wellknown of this manifestation are the springs at …

A radiocarbon method and multi-tracer approach to quantifying groundwater discharge to coastal waters
… Carolina. In coastal North Carolina, fresh water artesian discharge is characterized by a low Δ14C signature acquired from the carbonate aquifer rock. Mixing models were used to evaluate the inputs from potential sources of DIC-Δ14C to each estuary, including seawater, springs, fresh water stream …

Bioassessment and the Partitioning of Community Composition and Diversity Across Spatial Scales in Wetlands of the Bonneville Basin
… steep, gravelly slopes of these ranges. Numerous artesian desert springs are present at the base of the mountains and in the valley floors that form various sizes of both isolated wetlands and wetland complexes. Many these wetlands are some of the most unique and currently some of the most …

Ground water reservoir response to earth tides
Existing models for the response of artesian aquifers to earth tides have been examined anda new model developed. A formula for the computation of poresity from tidal water level measurement is presented. Tidal water level fluctuations in three artesian wells of southwest Virginia were recorded, …

A Conceptual Model for the Development and Persistence of Soap Holes (Unique Prairie Groundwater Discharge Features)
… glacial sediments under strong flowing artesian conditions, resulting in quick conditions and liquefaction. Geoelectric and hydraulic conductivity contrasts (2-5 orders of magnitude), as well as groundwater geochemistry, suggest preferential groundwater flow of artesian aquifer …

A radiocarbon method and multi-tracer approach to quantifying groundwater discharge to coastal waters
… Carolina. In coastal North Carolina, fresh water artesian discharge is characterized by a low A14C signature acquired from the carbonate aquifer rock. Mixing models were used to evaluate the inputs from potential sources of DIC-A'4C to each estuary, including seawater, springs, fresh water stream …

A garden in the desert? A regional study of ranching and farming in Southern Nevada, 1870-1930
… for agriculture. The availability of cheap land, artesian water, railroad transportation, nearby markets, along with enthusiastic support from town boosters facilitated their determined efforts to develop agriculture as a viable economic activity. Ranching and farming played an important role in …

Measurement of radio-frequency magnetic fluctuations in the VTF magnetic reconnection experiment
… created, and magnetic fluctuations in all three artesian directions were measured in the 1-101)MHz range. A preliminary hodogram analysis of the fluctuation spectra found the propagation direction of low-frequency (1-5MHz) electromagnetic waves to be parallel to the direction of the plasma …

The geochemistry of water-filled sinkholes at Bitter Lake National Wildlife Refuge, Roswell, NM : implications for hydrochemical evolution and trophic support
… found at the discharge region for the Roswell Artesian Basin, recharged by upwardly flowing artesian springs. Constant head is confirmed by a lack of measured change in depth during two sampling sessions (October 2008, May 2009), low relief (<10m change across study area), and deployment of …

The Investigation Of Okhissa Dam Using A Real-Time Monitoring System
… Prior to this investigation of Okhissa Dam artesian conditions were present. The Artesian conditions were alleviated by placing additional fill material on the downstream side. It is presumed these high piezometric water levels resulted from pressure in the aquifer due to communication from …

Going up Bell's Hill : a social history of a diverse, Waco, Texas, community in the industrial new south.
… economic diversity. From its early history when artesian wells attracted investors, Bell's Hill became a working-class community where industries located adjacent to the nearby railroad, attracted a growing, diverse population. Once there, residents built strong social institutions and developed …

Evaluation of Spring Discharge for Characterization of Groundwater Flow in Fractured Rock Aquifers: A Case Study from the Blue Ridge Province, VA
… for some springs, while other springs and artesian wells are sourced only in the deep aquifer. The technique is suitable for rapid characterization of flow paths leading to spring outlets. Rapid characterization is important for evaluation of potential water quality problems arising from …

Travertine from Egypt's Western Desert: a terrestrial record of North African paleohydrology and paleoclimate during the late Pleistocene
… tapping of modern pumped waters relative to past artesian conditions. Travertine stable isotopic signatures from Dahkla also differ from the other oases and are interpreted to reflect its lacustrine rather than spring-mound depositional environment. These observations lead to a depositional model …

Hydrochemical Response of Groundwater Following the 2020 Monte Cristo Range Earthquake Sequence within Mineral and Esmeralda Counties, NV
… Marsh (CM) located 5 km from the epicenter; an artesian thermal well from Fish Lake Valley (FLV); a well at Willow Ranch (WR) tapping cool water above the FLV waters; and a spring along Mina Dump Road (MD) located 15 km north of the Candelaria fault on the Benton Springs Fault. GPS and InSAR …

Seismicity and structure of the eastern Gawler Craton and Lake Eyre region
… of fluid-assisted hydrofracturing, as the Great Artesian Basin groundwater is found to circulate through the upper crust and interact with mantle-derived volatiles. Thus, the thesis provides new constraints on the crustal structure of a hitherto under-explored region in the heart of the …
