  • Report: Groundwater pumping in California has land sinking

    Vast areas of California's Central Valley are sinking faster than in the past as massive amounts of groundwater are pumped during the historic drought, state officials said, citing new research by NASA scientists. They said Wednesday that the data show the ground is sinking nearly two inches each month in some places, putting roads, bridges ...

  • High quality groundwater sampling

    Representative Samples A project manager’s goal for groundwater sampling is to collect samples that are representative of actual in-situ conditions, and to maintain sample integrity by minimizing the changes in sample quality and chemistry during collection. Sampling has evolved from earlier techniques of bailing and high rate pumping, to techniques of minimal drawdown and low flow ...

  • Coordinated groundwater recharge needed

    The massive rains over California last month are not just a blessing but also a curse: a curse because the intensity of rain causes serious problems with flooding, erosion and landslides. Every watershed in California should therefore have a coordinated program to intentionally capture flood flows and recharge groundwater aquifers. Extreme weather is one reason so much reservoir storage has been ...

  • Groundwater development is not the answer for Africa

    Research showing the extent of Africa's significant groundwater reserves should not detract from the real challenges to meeting the continent's drinking water demands, argues Roger Calow, head of the Overseas Development Institute's Water Policy Programme. Recent research has found that Africa's groundwater resources — water found in non-renewable aquifers underground — are 100 times ...

  • Groundwater evaluation platform

    SuperGeo Technologies has developed a data platform for groundwater recharge areas in order to evaluate the recharge potential. The platform is able to assist researchers in delimiting groundwater recharge areas and also in determining parameters such as recharge rate, pumping rate, flow rate and recharge potential. Water resource protection is one of the most important policies in Taiwan. ...

  • Nanoparticles decontaminate groundwater

    Since their invention a decade ago at Lehigh University, iron nanoparticles 1,000 times thinner than a human hair have demonstrated an unprecedented ability to clean contaminated groundwater. The palladium-coated particles have remediated more than 50 toxic waste sites in the US and other countries in 10 times faster than traditional pump-and-treat methods. Researchers at Lehigh University have ...

  • Toxic compounds in groundwater

    Research is being conducted on degrading a toxic compound found in groundwater systems around the world Vinyl chloride is a cancer-causing compound formed from solvents in groundwater systems under anaerobic conditions. These solvents are used in many industrial applications around the world and often belong to the most encountered groundwater pollutants in industrialized countries. Groundwater ...

  • Deep Groundwater & Dissolved Gas Sampling with Double Valve Pumps

    Sampling groundwater from deep wells is a challenge on its own, but add to that the need for accurate dissolved gas analysis, and the task gets that much harder. Low Flow, Deep Groundwater Sampling HydroTerra, a leading Australian company, and exclusive distributor of Solinst products, provides environmental monitoring solutions. ...

  • Spanish earthquake could have been triggered by groundwater pumping

    An earthquake that killed nine people in Lorca, Spain, last year could have been triggered by groundwater being drained from the area for use in irrigation, according to scientists. The study found that the ground moved in the same places as subsidence has been occurring since the 1960s, due to the extraction of groundwater. In Europe, earthquakes are most common in southern and ...

  • High quality groundwater sampling explained

    The Solinst Technical Bulletin on High Quality Groundwater Sampling explains how to obtain representative groundwater samples using Solinst Bladder Pumps, 464 Electronic Pump Control Units and our 12 Volt Compressor. Solinst Bladder Pumps are designed for sampling in a variety of applications and are ideal for obtaining VOC samples. This bulletin describes where it is best to use stainless steel ...

  • Jordan - Groundwater to save the capital, for a while

    Bundles of massive pipes lay along the 30 kilometre road from Amman’s main airport to the city, giving commuters an unusual scene to behold, and the government a tough bargain to quench the thirst for rapid economic development. A taxi driver explains that these pipes will be installed along a stretch of 350 kilometres to the Disi aquifer in the south of Jordan. “There is no other ...

    The Environment Agency has recently renewed its contract for groundwater modelling software for up to a further 3 years. The Groundwater Vistas and Aquifer software is supplied by ESI, the UK's leading independent soil and groundwater consultancy. ...

  • New map of global groundwater depths

    Despite groundwater’s importance to ecosystems, little is known about its global distribution. Researchers have now developed a model to map groundwater, revealing that ecosystems covering 22-32% of the Earth’s surface rely on this important resource. Groundwater is vital for many ecosystems, providing crucial support to plants and animals, especially during droughts. ...
