  • 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 ...

  • LNAPL At Petroleum Product Terminal - Case Study

    ABSTRACT BOS 200® was injected at a refined petroleum product terminal to remediate LNAPL in groundwater. Within one year after treatment, the site received a No Further Action status. CHALLENGES The remedial goal was to eliminate the reoccurrence of light non-aqueous phase liquid (LNAPL) which persisted with no apparent pattern. Annual ...

  • An approximate model on three-dimensional groundwater infiltration in sewer systems

    Groundwater infiltration through cracked sewer pipes has caused significant economic losses. This paper presents a three-dimensional analytical expression for calculating the steady-state groundwater infiltration rate into sewer systems. As an extension of the previously developed two-dimensional model by the author, this new model can be used to simulate the infiltration through an orifice ...

  • Large Precipitation Events are Critical in Replenishing Groundwater Resources

    Large precipitation events that occur about every 10 years are a critical source of recharge for replenishing groundwater resources, according to a new study by the U.S. Geological Survey and the Bureau of Reclamation. Groundwater is a vital source of water in the western United States, and will be increasingly ...

  • Groundwater discharge downstream of an arid inland river in Northwestern China

    Nalenggele River is an inland river located in the arid, fragile ecological environment area in Northwestern China. Groundwater discharge to the river can significantly impact the ecologic environment in the Nalenggele River basin, but few hydrogeological studies have been conducted in the inland arid basin. In this paper, two sections were chosen to analyze the groundwater discharge in the ...

  • Submarine groundwater discharge and alkaline earth element dynamics in a deltaic coastal setting

    Submarine groundwater discharge is a process that is often considered negligible in deltaic systems given their low gradient and fine-grained sediment. However, hydrologic budgets and radon surveys indicate that it may be a significant component of the Mississippi River Delta system. To more concretely indicate groundwater's contribution to the local environment, we conducted an analysis of ...

  • New study assesses the global volume and distribution of “modern” groundwater

    Groundwater has long been an important resource for spraying, drinking water, energy production and more, but getting a clear picture of how much is available and being recharged over time has been a challenge. Now an international group of hydrologists led by Tom Gleeson, engineering professor at the ...

  • Evaluation of submarine groundwater discharge into the northern Bohai Bay, China using 226Ra

    Submarine groundwater discharge (SGD) has been widely recognized as a significant source of water and dissolved material transport from land to ocean. To quantify SGD into the northern Bohai Bay, China, naturally occurring radium isotope (226Ra) was measured in water samples collected along two transects in September 2012. Based on a tidal prism model, two different flushing times of the ...

  • Groundwater banking: opportunities and management challenges

    Groundwater banking is the use of aquifers to store water to balance seasonal or longer-term variations in supply and demand. The large storage capacity provided by aquifers can be a valuable tool for conjunctive use of surface water and groundwater as well as other elements of integrated water resources management. Successful groundwater banking requires favorable hydrogeological conditions to ...

  • Management and protection of groundwater resources in semi–arid zones: application of hydrochemical methodologies to Essaouira Synclinal Basin, Morocco

    The water resources of the Essaouira basin are characteristic of a semi–arid climate. It is a coastal aquifer located on the Atlantic coastline, corresponding to a sedimentary basin with an area of about 200 km². The geological structures delineate a syncline bordered by the Tidzi diapir of Triassic age which outcrops to the E and S. In the Essaouira basin, a multi–aquifer composed of detrital ...

  • Chemical composition of groundwaters in the Hornsund region, southern Spitsbergen

    Chemical composition of groundwaters was investigated in the region of the Hornsund fjord (southern Spitsbergen). The investigations were conducted during polar expeditions organized by the University of Wroclaw in two summer seasons of 2003 and 2006. Three zones of groundwater circulation: suprapermafrost, intrapermafrost and subpermafrost, were identified in areas of perennial permafrost in ...

  • Assessment of groundwater resources using climatic and hydrologic budget methods

    The Pageru River basin is situated in drought prone areas of the Rayalaseema region, Andhra Pradesh, South–India. In the absence of perennial surface water bodies, groundwater is an important source of water and has played an important role in developing industry, agricultural and domestic supply. In the present study, the efforts have been made to assess the groundwater resources using both ...

  • Estimating the submarine groundwater and nutrients discharge of Yellow River delta with cross-section method

    In this paper, cross-section method was used to estimate the groundwater and nutrients discharge fluxing to the Bohai Sea from the Yellow River Delta. The flux of shallow phreatic groundwater (within 10 m) in the Yellow River Farm discharging into sea was 2.9 × 10−5 m3/m d in 2004 and 3.1 × 10−5 m3/m d in 2005. Time distribution monthly mean flux is consistent with the Yellow River's runoff but ...

  • Performance of intermittent aeration reactor on NH4-N removal from groundwater resources

    To study the effect of intermittent aeration period on ammonium–nitrogen (NH4-N) removal from groundwater resources, synthetic groundwater was prepared and three reactors were operated under different conditions – “reactor A” under continuous aeration, “reactor B” under 6 h intermittent aeration, and “reactor C” under 2 h intermittent aeration. To facilitate denitrification simultaneously with ...

  • San Diego formation groundwater development and storage potential.

    Groundwater as a resource has been little utilized in San Diego County, California, compared to neighboring counties to the north. The San Diego formation in southwestern San Diego County is one resource that has seen limited utilization historically, but in recent years has been viewed with increasing interest by local agencies for expanded groundwater development. Potential uses include ...

  • Wet water v. paper water: water management under the 1980 Arizona groundwater code.

    The Arizona Groundwater Management Code was enacted in 1980 to address the trend of widespread groundwater depletion across the State. The Code limits withdrawals of groundwater within designated areas (known as Active Management Areas or AMAs) to holders of groundwater rights, service area rights, groundwater withdrawal permits, and small domestic water users. Each AMA is required to maintain a ...
