An integrated approach to sustainable groundwater development and management in Nigeria

  Nigeria has greater challenges when it comes to groundwater development and management. The management of the resource is lagging behind the pace of development, and often, very little control is exercised in its exploitation. The current groundwater resources development and supply status is unacceptably low and needs a major transformation. With the rapid growth in population, urbanization,...

Effects of gas flaring on surface and ground waters in Delta State, Nigeria

  Surface and groundwater samples from gas flared region of Warri and a neighboring town, Abraka, where minimal gas flaring activity takes place were analyzed for their major, minor and trace element constituents and some physical characteristics. The results were evaluated with a view to determine and compare the quality and potability of the water from areas of high gas flaring activity with samples...

Geochemical modelling of uranium speciation in the subsurface aquatic environment of Punjab State in India

  Geochemical models like MEDUSA (make equilibrium diagrams using sophisticated algorithms) and the PRHEEQC versions 2 have been used to assess the uranium speciation under the influence of redox conditions and complexant concentration in ground water. For this study, the groundwater samples (bore well and hand pump) were analysed for different geochemical parameters including uranium. Using a...
