groundwater quality management is one of the most important issues in many arid and semi-arid regions, including iran.nitrate (no3-) is one of the most common anions contaminating groundwater. this study aimed to range nitrateconcentrations in water resources in bahabad plain in yazd province. to evaluate the nitrate data in this descriptive study,260 nitrate samples from 13 wells in bahabad we...

abstract surface water restriction and supply variation of these resources causes of over extraction of groundwater and unbalance between feed and extraction of groundwater in iran. agricultural sector as the biggest consumer of water resources has the most share of this unsustainability. this paper studies the conjunctive use of surface and groundwater in agronomy production in qazvin basin, o...

Characterization of groundwater quality allows the evaluation of groundwater pollution and provides information for better management of groundwater resources. This study characterized the shallow groundwater quality and its spatial and seasonal variations in the Lower St. Johns River Basin, Florida, USA, under agricultural, forest, wastewater, and residential land uses using field measurements...

Water resources of a country constitute one of its vital assets. India receives annual precipitation of about 4000 km. The rainfall in India shows very high spatial and temporal variability and paradox of the situation is that Mousinram near Cherrapunji, which receives the highest rainfall in the world, also suffers from a shortage of water during the non-rainy season, almost every year. The to...

We estimated vulnerability and pollution risk of groundwater at the pan-African scale. We therefore compiled the most recent continental scale information on soil, land use, geology, hydrogeology and climate in a Geographical Information System (GIS) at a resolution of 15 km × 15 km and at the scale of 1:60,000,000. The groundwater vulnerability map was constructed by means of the DRASTIC metho...
