  • Treatment of abstracted groundwater

    Since abstracted groundwater can consist of a complex mixture of river bank filtrate and polder water, which have different origins and compositions, its treatment is challenging . An article in Drinking Water Engineering and Science discusses the effect of the properties of this mixture on the production of drinking water. In the Netherlands, over 60% of ...


  • Contaminants in US groundwater

    According to a new study by the USGS, more than 20% of untreated water samples from 932 public wells across the US contained at least one contaminant at levels of potential health concern. About one-third of the US population receive their drinking water from such a system. The USGS study (Contaminants in Groundwater used for ...


  • Gas analyser helps reveal NITRABAR success

    A portable FTIR multiparameter gas analyser from Quantitech is helping researchers at the University of Strathclyde to prove the efficacy of a novel technique ('NITRABAR' - an EC LIFE Environment Project) that helps remove nitrate pollution from groundwater.

  • Scientists develop improved groundwater forecasting model

    Scientists in India have developed a more efficient computing model to predict monthly changes in groundwater, which is depleted in many areas of developing countries because of damaged soils and poor irrigation practices. A team of scientists based in India's four southern states used the concept of an 'artificial neural network' (ANN), a computing technique that mimics the way millions of ...

  • Journal article evaluates methane sources in groundwater in Pennsylvania

    The findings of a new study in the journal Groundwater suggest that methane concentrations in Susquehanna County water wells in Pennsylvania can be explained without the migration of Marcellus shale gas due to hydraulic fracturing. “Testing of 1,701 water wells in northeastern Pennsylvania shows that methane is ubiquitous in groundwater, with higher concentrations observed in valleys vs. ...

  • 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 ...

  • Scientists Assess 100 years of Los Angeles Groundwater Replenishment

    A new study offers the most sophisticated analyses to date on how Los Angeles-area groundwater supplies are replenished. The analyses provide water managers with a clearer understanding of the sources and amount of available groundwater in the region – information that is important for planning and management of the vital resource. A new study offers the most sophisticated analyses to ...

  • Public Comment Phase: NGWA’s Groundwater and PFAS: State of Knowledge and Practice

    The purpose of Groundwater and PFAS: State of Knowledge and Practice is to identify for the defined audiences the known science and knowledge related to PFAS compounds present in groundwater and the subsurface, as well as the current state of the art in practices relating to the ecological impacts, as well as the anthropogenic uses of groundwater.  The document will also identify gaps in ...

  • We are Gonna Need a Bigger Pump

    The Problem: At a large industrial site, traditional horizontal and vertical extent investigations failed to reveal what eventually turned out to be highly localized seams of Trichloroethylene (TCE) DNAPL at areas of the property where unusual lithology came into play.  In addition to the “hide & seek” nature of finding the contamination in these areas, it became ...

  • New sewage sampler enables real-time control

    HACH LANGE has launched an innovative new wastewater sampling system, which will open up a new world of opportunity by enabling water companies to continuously monitor sewage at the plant inlet.
