Aquifer Characterization: The Case of Hawassa City Aquifer
, 2021 Hydrogeologists and other water experts agree on that the effective groundwater management requires: firstly, a good understanding of the aquifer system; secondly, identification of practical measures to control abstraction; and thirdly, improvement in groundwater resource through artificial recharge.

Anthropogenic depletion of Iran’s aquifers [PDF]
Proceedings of the National Academy of Sciences, 2021 Significance Iran is facing a state of water bankruptcy that threatens its socioeconomic development and natural environments. Using an exceptionally rich measured groundwater dataset, we illustrate the extent and severity of Iran’s groundwater depletion and salinization problems during the 2002 to 2015 period, when the number of

Characterising aquifer treatment for pathogens in managed aquifer recharge
Water Science and Technology, 2010 In this study the value of subsurface treatment of urban stormwater during Aquifer Storage Transfer Recovery (ASTR) is characterised using quantitative microbial risk assessment (QMRA) methodology. The ASTR project utilizes a multi-barrier treatment train to treat urban stormwater but to date the role of the aquifer has not been quantified.

Molybdenum Mobility During Managed Aquifer Recharge in Carbonate Aquifers
Environmental Science & Technology, 2023 The mobility of molybdenum (Mo) in groundwater systems has received little attention, although a high intake of Mo is known to be detrimental to human and animal health. Here, we used a comprehensive hydrochemical data set collected during a multi-cycle aquifer storage and recovery test to study the mechanisms that control the mobility of Mo under ...

Determination of In Situ Bacterial Growth Rates in Aquifers and Aquifer Sediments [PDF]
Applied and Environmental Microbiology, 2003 ABSTRACTLaboratory and field-scale studies with stained cells were performed to monitor cell growth in groundwater systems. During cell division, the fluorescence intensity of the protein stain 5-(and 6-)-carboxyfluorescein diacetate succinimidyl ester (CFDA/SE) for each cell is halved, and the intensity can be tracked with a flow cytometer.

Saturated-Unsaturated flow in a Compressible Leaky-unconfined Aquifer [PDF]
, 2012 An analytical solution is developed for three-dimensional flow towards a partially penetrating large-diameter well in an unconfined aquifer bounded below by an aquitard of finite or semi-infinite extent.

The impact of boundary conditions on CO2 capacity estimation in aquifers [PDF]
, 2010 The boundary conditions of an aquifer determine the extent to which fluids (including formation water and CO2) and pressure can be transferred into adjacent geological formations, either laterally or vertically.

Weighing risks against GHG reduction benefits in emerging green technologies
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Green technologies represent promising strategies for mitigating carbon emissions and combating global warming. However, their implementation in civil and industrial applications is not without risks, as intrinsic uncertainties and latent safety concerns can threaten their effective deployment.

Preliminary Investigation of the Ground-Water Resources of Baxter, Fulton, Izard and Sharp Counties, Arkansas [PDF]
, 1980 One hundred and seventy-seven drillers\u27 well reports were used to investigate the groundwater resources of Baxter, Fulton, Izard, and Sharp counties. The most widely utilized aquifer zone is composed of the Cotter and Jefferson City dolomites.
