Saltwater intrusion (SWI) is a type of pollution that adversely affects the quality groundwater in coastal aquifers. The Nile Delta aquifer (NDA) Egypt contains large amount freshwater. Increasing abstraction from and sea level rise have led to an increase SWI, which has reached up 100 km inland. Therefore, practical measures are required prevent further SWI. This study aims identify optimal we...

Old Las Salinas spring in Medina del Campo, Duero river basin, central Spain. Campo groundwater body (MCGWB) is a multilayer semiconfined aquifer subject to intensive pumping since the 1970’s, where current existence of spas there used be traditional baths could confirm deep flow paths. The old (OSLS) saline anomaly an with predominance CaCO3H waters whose occurrence has not yet been formally e...

This paper presents results of hydro-chemical processes controlling groundwater chemical composition, using an integrated application of hierarchical cluster analysis and factor analysis of a major ion data set of groundwater from Mighan playa aquifer. Cluster analysis classified samples into four clusters(A, B, C and D) according to their dominant chemical composition: cluster A (dominant comp...

Globally, about 54 million ha of cropland are irrigated with saline water. the soils associated 1 billion affected by salinization. A small decrease in irrigation water salinity (and soil salinity) can result a disproportionally large increase crop yield. This study uses zero-valent iron desalination reactor to effect surface processing ground water, obtained from an aquifer, partially desalina...

In the Marrakech region of Morocco, where water resources are particularly limited, excessive salinity has been measured in from some wells intended for human consumption and irrigation. Moreover, start-up a mine exploitation polymetallic sulfide deposit progress work have revealed existence very saline deep groundwater with total mineralization over 80 g/L. The hydrogeochemical study using con...

Wells screened across multiple aquifers can provide pathways for the movement of surprisingly large volumes of groundwater to confined aquifers used for public water supply (PWS). Using a simple numerical model, we examine the impact of several pumping scenarios on leakage from an unconfined aquifer to a confined aquifer and conclude that a single inactive multi-aquifer well can contribute near...
