  • Leachate and Groundwater Quality in Lagos, Nigeria.

    ABSTRACT Water as a gift of nature is generally believed to have no enemy. Despite the abundance of fresh water on the earth, many regions are in deep crisis of water shortage due to there being polluted by human activities, or the ever increasing demand by industrialization and high population growth. Thus, groundwater is the alternative source of fresh water in areas where surface water is ...


  • Assessment of groundwater quality in sunamganj of Bangladesh

    Huge quantities of groundwater, particularly from the shallow aquifers, are used for irrigation in Bangladesh and in the absence of adequate surface water in the dry season, irrigation becomes heavily dependent on groundwater. The water quality management is essential for long-term irrigation system as it persuades the soil properties. In irrigation water evaluation, emphasis is given on chemical ...

  • Evaluation of groundwater qualities in a paddy-dominated alluvial fan

    Analytically assessing groundwater quality is indispensable for sustainable use of groundwater and its effective pollution controls. A large volume of groundwater is stored in the Tedori River alluvial fan one of which of the predominant land uses being irrigated paddy fields. Much groundwater under the fan is used for drinking and industrial purposes. For assessing agricultural activities at ...

  • Groundwater Remediation

    Groundwater remediation or clean-up is required when concentrations of contaminants exceed or are expected to exceed predetermined levels for the type of resource that is impacted (Grossman et.al., 2008). For example, lead levels in drinking water should not exceed the EPA action level of 0.015 mg/L. What caused the high levels of lead? How can the lead be removed from the aquifer? (Grossman ...

  • Evaluation of groundwater quality and its suitability for drinking purpose in Rajshahi City, Bangladesh

    A study was conducted to evaluate the hydrochemical processes controlling the water quality variations and to determine the water type of groundwater in Rajshahi City, Bangladesh, for drinking purposes. A total of 120 shallow and deep tubewell water samples were collected in pre- and post-monsoon seasons during the year 2008–2009 and analyzed for various physico-chemical parameters. The results ...

  • Effect of soil-use on deep groundwater quality in Southern Chile

    This study evaluated the effects of farming activities on the quality of deep well water in Southern Chile. In this area, the use of fertilisers is becoming more widespread and the accumulation and poor management of cattle slurry and silage sub-products increases the risk of contamination. The study was carried out in the province of Osorno, where rainfall occurs all year round (maximum in ...

  • Application of a GIS-based DRASTIC model and groundwater quality index method for evaluation of groundwater vulnerability: a case study, Sefid-Dasht

    Pollution control and removal of pollutants from groundwater are a challenging and expensive task. The aims of this paper are to determine the aquifer vulnerability of Sefid-Dasht, in Chaharmahal and Bakhtiari province, Iran, using the DRASTIC model. In addition, the groundwater quality index (GQI) technique was applied to assess the groundwater quality and study the spatial variability of major ...

  • Impact of recycled water use at mammoth golf courses on basin groundwater quality

    ABSTRACT The Mammoth Community Water District’s proposed plan for recycled water use in golf course irrigation as a solution to the district’s water shortage problem develops concerns over protecting its basin groundwater quality. A detailed assessment through model development, and monitoring and testing is done in this study to determine the fate and transport of concerned pollutants in ...

  • Hydrogeochemistry and groundwater quality assessment of Astaneh–Kouchesfahan Plain, Northern Iran

    In this study, the hydrochemical characteristics of 230 bore well samples were analysed in Astaneh–Kouchesfahan Plain. Data interpretation shows that alkaline earths (Ca2+ and Mg2+) exceed the alkalis (Na+ and K+) and weak acids (HCO3−) exceed the strong acids (Cl− and SO42−) and ...

  • Stochastic hydro-economic model for groundwater quality management using Bayesian networks

    A strong normative development in Europe, including the Nitrate Directive (1991) and the Water Framework Directive (WFD) (2000), has been promulgated. The WFD states that all water bodies have to reach a good quantitative and chemical status by 2015. It is necessary to consider different objectives, often in conflict, for tackling a suitable assessment of the impacts generated by water policies ...

  • Impact of treated wastewater on groundwater quality in the region of Tiznit (Morocco)

    The Tiznit region has an arid to semi-arid climate. Rainfall is scarce and the reuse of wastewater for crop irrigation is common, and consequently groundwater can be contaminated by chemical and biological pollutants. A wastewater treatment plant is constructed with the aim of producing water suitable for reuse in agriculture and reducing groundwater pollution. The aim of this study is to assess ...
