They are being exploited, via a ‘standing column’ heat pump arrangement in Markham No. 3 shaft, to produce thermal energy. From 2012, water was pumped from 235 m below g...

Owing to increased demands on ground water accompanied by increased drawdowns, technologies that use recharge options, such as aquifer storage recovery (ASR), are being used to optimize available water resources and reduce adverse effects of pumping. In this paper, three representative ground water flow models were created to assess the impact of hydrogeologic and operational parameters/factors...

Compared to surface water, groundwater resources are the primary source of water supply in arid and semi-arid regions of Iran, hence the importance of the management of these resources .  In this regard, we assessed the effects of landuse changes on the qualitative and quantitative status of groundwater resources in Eshtehard region, Iran. Through processing and analyzing the satellite images, ...

background and purpose: fluoride is one of the drinking water contaminants regulated by epa. this ion, in low doses in the mouth reduces tooth decay without health risk and at much higher doses causes health complications and can be toxic. the major sources of exposure to fluoride are drinking water, food, dental products, and pesticides. the biggest contributor to exposure for most people in i...

India is a subcontinent country with large amount of resources, though many places in India people uses ground water as only the sources for drinking and domestic purpose. But ground water is not safe in most of the places. Arsenic and Fluoride are the major concern of ground water pollution in these days. The Indian Ministry of Water Resources informs that several districts of nine states (i.e...

qorveh – dehgolan aquifer is one of the ground water resources in kurdistan. increase in pumping of water has dropped water table level significantly. this study considers the relationship of fluctuations in precipitation, humidity and evaporation with ground water table level. after preparing the base map and the rainfall data accuracy, isohyetal map of basin was drown. based on isohyetal ma...
