Impacts of energy price changes on the financial viability of agricultural groundwater wells in Tulkarm district, Palestine
Water scarcity has often been recognised as a major challenge to sustainable development and viability of the anticipated Palestinian State. Recently, after the evolution of increasing oil prices, energy has become another major challenge. Groundwater, which is the major source for Palestinians, depends greatly on diesel and electricity whose prices have increased drastically during the past ...

Monthly groundwater level prediction using ANN and neuro-fuzzy models: a case study on Kerman plain, Iran
The prediction of groundwater levels in a well has immense importance in the management of groundwater resources, especially in arid regions. This paper investigates the abilities of neuro-fuzzy (NF) and artificial neural network (ANN) techniques to predict the groundwater levels. Two different NF and ANN models comprise various combinations of monthly variablities, that is, air temperature, ...

Fe Removal Drinking Water- Case Study
A water utility in the state of Delaware has potable groundwater wells with high levels of Fe (15 ppm peeks) with a combined flow rate of 1 MGD. The existing biological filter needed replacement due to extensive fouling, cost and excessive liquid waste structure. The well location is at a National Guard Air Force base. The iron needs to be removed in a cost effective manner, with minimal waste ...

Several natural indicators of radial well ageing at the Belgrade Groundwater Source, part 1
Over time, the radial collector wells of the Belgrade Groundwater Source, located in the alluvial sediments of the Sava River, exhibit a decline in discharge and a reduction in operating efficiency due to well ageing. An increase in hydraulic losses at the lateral screens, due to chemical and biochemical clogging, has been identified as the primary cause. Certain hydrogeological, hydrochemical ...

Relations between groundwater flow in an unconfined aquifer and seepage patterns in a closed-basin lake in glacial terrain
Groundwater dynamics affect lake water budgets, but its major factors and mechanisms still need clarification. This study evaluates the effects of surrounding groundwater flow on seepage direction and assesses factors that affect seepage flux in a closed-basin lake in northeastern Estonia – Lake Martiska. A piezometric map was used to determine directions of groundwater flow around the ...

Subsurface iron and arsenic removal: low-cost technology for community-based water supply in Bangladesh
The principle of subsurface or in situ iron and arsenic removal is that aerated water is periodically injected into an anoxic aquifer through a tube well, displacing groundwater containing Fe(II). An oxidation zone is created around the tube well where Fe(II) is oxidised. The freshly formed iron hydroxide surfaces provide new sorption sites for soluble Fe(II) and arsenic. The system's efficiency ...
