  • 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 ...

  • World Bank: groundwater management specialist

    The World Bank is currently looking for a senior water resources specialist specializing in groundwater management to join the South Asia water team. The World Bank’s regional portfolio is in South Asia comprises over $5 billion of lending, of which around half is for water supply and sanitation and half for water resource and irrigation projects and a strong focus in India. These projects ...


  • Bank filtration as managed surface-groundwater interaction

    Riverbank Filtration (RBF) is a managed surface-groundwater interaction process where surface water is induced to flow to pumping wells installed on the banks of rivers and lakes. We present the surface-groundwater interaction issues at various geomorphologic settings, from the headwaters of a river to its confluence with the oceans/lakes. In each reach, the factors for the sustainable operation ...

  • Of transboundary basins, integrated water resources management (IWRM) and second best solutions: the case of groundwater banking in Central Asia

    This paper tells the story of trade-off between hydropower and irrigation and its implications for groundwater use in Syrdarya basin in Central Asia. With the independence of the central Asian republics, this trade-off has become a transboundary issue. Efforts to coordinate bilateral action using integrated water resources management (IWRM) principles of basin-wide cooperation have not yet ...

  • India - Groundwater governance case study

    Groundwater comprises 97 percent of the worlds readily accessible freshwater and provides the rural, urban, industrial and irrigation water supply needs of 2 billion people around the world. As the more easily accessed surface water resources are already being used, pressure on groundwater is growing. In the last few decades, this pressure has been evident through rapidly increasing pumping of ...

  • Why it’s time to elevate groundwater

    Groundwater stored in the earth’s crust underpins all our lives – the ultimate source of freshwater for billions has become victim of over-extraction and the ultimate sink for pollutants.   For too long, not enough has been done to regulate the use of this precious, on-demand resource and manage disposal of waste. If rates of groundwater depletion have tripled in the past 3 ...

  • The ponds of Hattuša – early groundwater management in the Hittite kingdom

    From about 1650 until 1200 BC Hattuša (pronounced Hattusha) was the capital of the Hittite Empire in central Asia Minor. On the steep terrain of today's ruined city lived and worked thousands of people whose homes, cattle, tools and places of worship had to be supplied with water. The question arose regarding how water was conveyed into the large-scale ponds in the urban area. The ...

  • Groundwater/surface water interactions along the Curtiss reach of the San Pedro River.

    A reach of the San Pedro River flows east of the Apache Powder Superfund Site and west of the Town of St. David in Cochise County, Arizona. As a result of the remedial investigations associated with the Superfund Site, this reach has been surveyed extensively since the mid-1980’s from approximately the Escalante Crossing to the Pomerene Diversion. In particular, the section downstream from ...

  • Serological responses to Cryptosporidium antigens among women using riverbank-filtered water, conventionally filtered surface water and groundwater in Hungary

    ABSTRACTWe compared serological responses to Cryptosporidium parvum antigens using surplus sera from females undergoing routine screening for pregnancy from three counties in Hungary where bank-filtered surface water, conventionally filtered and disinfected surface water, and groundwater from either a karst or confined aquifer are commonly used for drinking water. The primary purpose was to ...

  • The dynamic of groundwater level in the lower reaches of Tarim River affected by transported water from upper reaches

    Using the grey system theory and the observed data from the monitoring section of Yingsu, the paper studied the dynamics of groundwater level in the lower reaches of Tarim River affected by transported water from upper reaches. The main findings are as follows: 1) the groundwater level has revealed an upward trend versus time since 2000, but downward trend versus the distance from the river ...

  • Groundwater and stream E. coli concentrations in coastal plain watersheds served by onsite wastewater and a municipal sewer treatment system

    The goal of this study was to determine if onsite wastewater treatment systems (OWS) were influencing groundwater and surface water Escherichia coli concentrations in a coastal plain watershed. Piezometers for groundwater monitoring were installed at four residences served by OWS and five residences served by a municipal wastewater treatment system (MWS). The residences were located in two ...

  • Nitrate pollution in groundwater in two selected areas from Cameroon and Chad in the Lake Chad basin

    The shallow aquifer in the Lake Chad basin is highly vulnerable to pollution. Analysis carried out on 316 wells and boreholes have showed a tendency towards an increase of nitrate values, exceeding 50 mg l−1. Nitrate concentrations ranged between about 1 and 300 mg l−1. Large variation in concentration was observed in wells and boreholes that are only short distances apart. High concentrations of ...

  • A Lakeside Community Tackles a WWTF Upgrade

    Blodgett Landing, a community of about 145 homes on the shores of Lake Sunapee in Newbury, New Hampshire, operates a 50,000-gpd wastewater treatment facility (WWTF) that is unable to meet current groundwater discharge standards with the existing Imhoff tank and sand filters/rapid infiltration basins (RIBs). A pilot project was begun in 2001 to reduce nitrate loadings to the groundwater. Effluent ...

  • Modelling present and future Po river interactions with alluvial aquifers (Low Po River Plain, Italy)

    A modelling study on a multi-layered confined/unconfined alluvial aquifer system was performed to quantify surface water/groundwater interactions. The calibrated groundwater flow model was used to forecast climate change impacts by implementing the results of a downscaled A1B model ensemble for the Po river valley. The modelled area is located in the north-western portion of the Ferrara Province ...

  • Dumping of the effluent of Punjab in Sindh

    The province of Punjab has been blessed with immense quantity of fresh groundwater. On the contrary, the quality of groundwater in the province of Sindh is mainly saline. There are very few pockets in Punjab where the quality of groundwater is saline. The commands of Punjnand Abbasia Canal and Fordwah Sadqia Canal, on the let bank of River Sutlej, are one of those pockets, which are underlain ...


  • Modelling the Long-term Release of Sulphate from Dump Sediments of an Abandoned Open Pit Lignite Mine

    The generation of acid drainage from overburden spoil piles at open-pit lignite mines impacts water quality in large parts of the Lusatian mining area in Germany. The Lohsa Mine was exploited until the early 1990s and is to be flooded by 2005. It will then be used as a reservoir basin for the river Spree. Future acidity and sulphate concentrations in the surface water are of great interest ...

  • GW monitoring in saxony

    Background During the hundred-year flood in 2002 in Eastern Germany the river “Elbe“ and a lot of rivers in the catchment area exceeded the banks and caused damages of millions within a short period of time. Often unnoticed, the groundwater level was rising extremely after a certain time. The time of rising groundwater took considerably longer than the actual flood, and caused enormous ...
