Regional groundwater monitoring network Vallei en Eem - Case Study
Project Regional groundwater monitoring network Vallei en Eem Client Platform Water Vallei en Eem Country The Netherlands Background and objective Since 2007, the ‘Municipal Water Management Act’ is in force, which introduces a duty of care for the groundwater. This new duty for care entails that municipalities are responsible for the prevention of structural groundwater ...

Beaver Dam Groundwater Survey Project, Utah - Case Study
In May 2014, we conducted seismoelectric survey for Willowstick Technologies LLC in Beaver Dam area, Utah, USA. According to our client’s requirement, we designed 3 seismoelectric survey lines, with total 50 measurement stations. After data processing and interpretation, we located 3 layers of aquifers. The red layers are the top and bottom of the first aquifer; the green ones for the ...

Economic Evaluation of the Cadiz Groundwater Storage and Dry Year Supply Project, Metropolitan Water District of Southern California
This report summarizes the Pacific Institute’s economic evaluation of the Cadiz groundwater storage and transfer project. The evaluation is consistent with and elaborates on the analysis previously submitted by Professor Charles Howe of the University of Colorado at Boulder, a highly experienced water resources economist, in response to the draft Environmental Impact Report. It also ...

Vista Clara delivers slim-line Javelin Wireline to Leibniz Institute of Applied Geophysics in Hanover Germany
In January 2020, Vista Clara President, Dave Walsh, traveled to Hanover, Germany to provide on-site training and support for the Leibniz Institute of Applied Geophysics (LIAG), one of the first customers to deploy the new Javelin 238 Wireline system. LIAG purchased the state-of-the-art Javelin Wireline including both 2.38 (60 mm) inch and 3.5 inch (90 mm) NMR logging tools in order to ...

Privatization of Water-Resource Development
This paper analyzes the inefficiencies from market power and return-flow externalities in private construction of a water project. The model pays special attention to increasing groundwater pumping costs, project set-up costs, limited project capacity, and return flow to the aquifer. For a given capacity, the return-flow externality causes project owners to construct the project too late when the ...

Evaluating the cumulative rainfall deviation approach for projecting groundwater levels under future climate
In south-western Australia (SWA) groundwater levels have been declining under the changing climate associated with a decline of rainfall. Possible future groundwater yields in SWA have been estimated under a range of climate change scenarios using a number of numerical groundwater models. For the Northern Perth Basin (NPB) in SWA, where no groundwater models were available, a relatively simple ...

Nitra-Seal Protects Multi-Acre Tampa Logistics Center- Case Study
A new, expansive logistics center in Tampa, Florida, was the site of a former brownfield, where past operations left petroleum hydrocarbons and methane contaminants in soil and groundwater. The project required a cost effective solution to mitigate the potential vapor intrusion risk from these contaminants. After reviewing multiple vapor intrusion mitigation system (VIMS) options, the project ...

Rapid Groundwater Exploration - Case Study
A Vehicle-Mounted Solution Using CrossOver CO730 Customer’s task The Swedish Geological Survey (SGU) has been engaged in groundwater exploration projects to investigate Sweden’s many glacial river deposits. The deposits are spread across the country and are the most significant groundwater resources for drinking water supplies in Sweden. SGU wanted a GPR solution to deploy rapidly to ...

Assessing climate change impact on root-zone water balance and groundwater levels
The present study employs regional climate model projections for assessing the impact of root-zone water balance and groundwater levels using crop and groundwater models. The projections from Hadley Regional Model 3 (HRM3) for A1B scenario showed an increase in temperature and rainfall (RF) of 1.8 °C and 328 mm, respectively, during mid-century (MC) (2021–2050) for Indian central Punjab. The ...

Natural background levels for chemicals in Icelandic aquifers
Information about natural background levels (NBLs) of chemicals in source waters allows water utilities to identify trends in drinking water contamination. We estimate NBLs for chemicals in source waters for Icelandic water utilities at both national levels with all data pooled, and according to geological regime. NBLs were derived by collecting samples from 79 aquifers considered largely ...

Cape Town Rushes to Produce More Fresh Water as ‘Day Zero’ Approaches
Residents focus on conservation as they prepare for taps running dry Cape Town, at the southern tip of South Africa, is surrounded by beautiful ocean vistas, but austere water conservation measures put in place to counter a third year of severe drought have thrown some shade on the idea of a sunny vacation there. The arrival of “Day Zero” — the day on which the taps of a ...

NAUE shores up Schwarze Elster´s detour case study
Lusatia is a region in Germany and Poland. The original meaning of Lusatia is something along the line of “swampy, wet meadows.” Lusatia is separated into two parts that, in terms of the landscape, are completely different: Upper Lusatia and Lower Lusatia. In the Northwest, Lower Lusatia is bordered by the Fläming ridge; and in the West it’s bordered by the Schwarze ...

Feasibility study of in-situ bioremediation for nitrobenzene-contaminated groundwater
Although many studies have simulated in-situ bioremediation of contaminated groundwater, most of them have not considered hydrochemical conditions and indigenous microorganisms, thus potentially rendering results inapplicable to actual in-situ groundwater bioremediation projects. This study focused on a nitrobenzene-contaminated groundwater site located in Jilin City, China. The actual ...

Membrane investment earns green light for brownfield site development
A contaminated brownfield site with a history of industrial use and failed development attempts has been given the green light for a much-needed local housing development thanks in part to a revolutionary barrier membrane. Permission to build nine new homes at Upper Bar, Newport, Shropshire was granted to Days Homes by the local council subject to a contamination investigation and satisfactory ...

Three-phase approach to improve deep groundwater supply availability in the Elidar district of Afar region of Ethiopia
This study provides new evidence on the effectiveness of a combined remote sensing and hydrogeological investigation method for deep groundwater development in complex geologic and geomorphologic situations in Ethiopia. The study was undertaken in the Elidar district of the Afar region of Northern Ethiopia. Due to the water availability and vegetation in this district, the majority of the ...

Project - Regional Groundwater Model for the Grand River Basin
Earthfx Incorporated developed a preliminary regional-scale groundwater model for the entire Grand River Conservation Authority area. The objective of the study was to better understand regional groundwater flow in the GRCA and evaluate the interaction between the river and the various aquifer systems in the basin. A key aspect of the study was the integration of multiple smaller-scale models ...
