  • Traditional Groundwater Diviners/Dowsers v/s Science and technology for Groundwater Exploration- a burning problem in the world

    Throughout world including India, the Groundwater diviners/dowsers claim having the special extra ordinary powers within them by which they could find out the site, for constructing/drilling the bore / wells having best yield of groundwater with definite depth and yields. Literate and illiterate villagers & farmers are highly affected by the ground water diviners. In our country, farmers and ...

  • Genetic diversity of Escherichia coli isolates from surface water and groundwater in a rural environment

    The genetic characteristics among Escherichia coli strains can be grouped by origin of isolation. Then, it is possible to use the genotypes as a tool to determine the source of water contamination. The aim of this study was to define water aptitude for human consumption in a rural basin and to assess the diversity of E. coli water populations. Thus, it was possible to ...

  • Application of leaching tests on phosphogypsum by infiltration-percolation

    The phosphoric acid production obtained by attacking phosphate rock by sulphuric acid cogenerates considerable quantities of phosphogypsum. The world cogeneration is estimated about 100–280 Mt per year. In another context of sustainable development, the phosphate chemical industry develops different ways of phosphogypsum valorization, which makes its storage stack in a suitable way for its ...

  • Modelling spatio-temporal heterogeneities in groundwater quality in Ghana: a multivariate chemometric approach

    Chemometric techniques were applied to evaluate the spatial and temporal heterogeneities in groundwater quality data for approximately 740 goldmining and agriculture-intensive locations in Ghana. The strongest linear and monotonic relationships occurred between Mn and Fe. Sixty-nine per cent of total variance in the dataset was explained by four variance factors: physicochemical properties, ...

  • Researchers: Current global groundwater recharge models inaccurate

    A large-scale analysis of existing water resource models used around the world has found some key processes are missing, which means estimates of water availability could be wrong and cannot be reliably used for making water management decisions. The international team of scientists found that important climate change impact models are wrong in some areas. One finding was that groundwater ...

  • Fighting saltwater intrusion into groundwater supplies

    As freshwater supplies around the world diminish, human intervention is needed to protect existing sources to slow the onset of water scarcity. One ongoing struggle is to preserve the water in underground aquifers, which cities often rely on for drinking water. Intrusion of saltwater into these underground supplies is rendering them unfit for consumption or irrigation. The rock and soil that ...

  • Multi-criteria analysis of site selection for groundwater recharge with treated municipal wastewater

    Geographic information systems (GIS) and remote sensing techniques are used as a decision support system to identify potential soil aquifer treatment (SAT) sites for groundwater recharge of Kerman aquifer, which is located in the southeast of Iran. These sites are identified using a single-objective multi-criteria analysis. To ensure technical feasibility, environmental sustainability, social ...

  • Local groundwater supply systems for remote settlements, current state and prospects for utilization: case studies from Serbia

    Water supply for remote rural settlements is a big issue in the Republic of Serbia. Most local supply systems are developed and maintained by the local community and are in a poor condition. Based on a national strategy, this issue should be resolved with the construction of regional systems using artificial reservoirs. In this paper, case studies from three areas in Serbia are shown in order ...

  • How food production impacts global groundwater supplies

    The ever-increasing global trade in food is accelerating groundwater depletion in many areas of the world, emptying aquifers faster than they can be naturally recharged, according to newly released research. Although groundwater depletion is a well-known and frequently studied issue, the new research focuses on how groundwater supplies are affected by international trade. Agricultural ...

  • Report documents effects of 40 years of groundwater withdrawal

    The cumulative effects of 40 years of groundwater withdrawals in the Houston-Galveston region are documented in a report from the United States Geological Survey. Decades of extensive withdrawals have caused the land to sink, or subside. The Houston-Galveston region is one of the largest areas of land surface subsidence in the U.S., according to the agency. Water withdrawals started as early as ...

  • Groundwater level response to hydrogeological factors in a semi-arid basin of Beijing, China

    In this study, the mode of groundwater level fluctuations is analyzed by statistical approaches for 51 monitoring wells located in a semi-arid basin in Beijing from 1998 to 2013. Firstly, a geostatistical method was performed to characterize the spatial and temporal behaviors of data sets and analyze the responding mechanism of groundwater level to hydrologic features using the Geostatistics ...

  • Rainfall changes blamed for India’s groundwater depletion

    Changes in rainfall may be responsible for reducing groundwater storage in India more than withdrawals for agricultural irrigation, according to a recently published analysis. Overextraction has long been thought to be responsible for declines in groundwater, but the researchers found less rainfall to be a more important factor. They believe it’s the result of higher temperatures in the ...

  • USGS surveys, models high plains groundwater resources

    A United States Geological Survey publication and model of groundwater resources in the Northern High Plains aquifer can be used to better understand the region’s water resources, a critical component of scientific water management. This type of comprehensive study has not been made in more than 30 years The models can be used to assess the flow, quantity, sources, and sinks of groundwater ...

  • Salting icy roads affects water supplies

    It’s basic chemistry: Saline water’s freezing point is much lower than fresh water’s, which can help keep ice from forming on roads. To reduce winter accidents, municipal and state workers often apply salt and other compounds to icy roads, because if not accidents start to happen and people end up in need cash in emergency. Unfortunately, this may have unintended consequences ...

  • Optimal location of artificial recharge of treated wastewater using fuzzy logic approach

    Increasing water demands in light of limited water resources have intensified exploitation and drawdown of groundwater. On the other hand, rising water demand has accelerated wastewater production. Therefore, urban wastewater management via artificial recharge may play a significant role in aquifer management. While site selection for artificial recharge projects is a major challenge, fuzzy ...

  • Making Australian groundwater data accessible: the value of collaboration

    Access to nationally consistent information is essential to support informed decision-making about Australia's vital groundwater resources. However, until now it has been difficult to depict a seamless national picture of groundwater resources and frame groundwater issues at a national scale. This is because groundwater data is typically managed locally without consistent format or ...

  • A transboundary aquifer of potential concern in Southern Africa

    Tuli Karoo transboundary aquifer (TBA) is shared between Botswana, South Africa and Zimbabwe in the Southern African Development Community (SADC) region. The TBA provides groundwater resources for various economic activities. Irrespective of the value offered by this TBA, there is very little research that has been conducted to improve understanding of the physical system and potential ...

  • Wavelet analysis–artificial neural network conjunction models for multi-scale monthly groundwater level predicting in an arid inland river basin, northwestern China

    In this study, the ability of a wavelet analysis–artificial neural network (WA-ANN) conjunction model for multi-scale monthly groundwater level forecasting was evaluated in an arid inland river basin, northwestern China. The WA-ANN models were obtained by combining discrete wavelet transformation with ANN. For WA-ANN model, three different input combinations were trialed in order to optimize ...
