Assessment of Aquifer Vulnerability Based on GIS and ARCGIS Methods: A Case Study of the Sana’a Basin (Yemen)
Groundwater Vulnerability DRASTIC GIS Sanaa Basin
2013/3/20
Groundwater is the main source of water in arid and semi-arid regions. Therefore, pollution of groundwater is a major issue because aquifers and the contained groundwater are inherently susceptible to...
Cylindrospermopsin in Water Supply Reservoirs in Brazil Determined by Immunochemical and Molecular Methods
Aphanizomenon Cyanobacteria Cylindrospermopsis Raciborskii CYN Sphaerospermopsis Aphanizomenoides Toxin
2013/3/19
It is reported for the first time in Brazil and South America the presence of cylindrospermopsin (CYN) in water supply reservoirs. CYN is a powerful hepatotoxic alkaloid implicated in outbreaks of hum...
Monitoring Groundwater Contamination Using Surface Electrical Resistivity and Geochemical Methods
Groundwater Uyo Urban Resistivity VES Dumpsites
2013/3/19
Surface electrical resistivity has been used as a tool in the detection of groundwater contamination. In this work, five geoelectric soundings with two at waste dumpsites have been carried out in Uyo,...
