  • Nitrate problems are soluble – but who pays?

    The world needs to double food production by 2050 but surface and ground water pollution from agricultural fertilizers will have to be reduced at the same time. Consequently, there is an urgent requirement for solutions that will permit the use of fertilisers to maximise yields whilst protecting the environment from pollution. Nitrate pollution in rivers, lakes, reservoirs and underground ...

  • Nitrate concentrations of groundwater increasing in many areas of US

    Nitrate is the most common chemical contaminant in the world’s ground water, including in aquifers used for drinking-water supply. Nitrate in drinking water of the United States is regulated by the U.S. Environmental Protection Agency (USEPA) because of concerns related to infant health and possible cancer risks. Use of man-made synthetic fertilizers has steadily increased since World War II, ...

  • Study: Two major U.S. aquifers contaminated by natural uranium

    Nearly 2 million people throughout the Great Plains and California live above aquifer sites contaminated with natural uranium that is mobilized by human-contributed nitrate, according to a study from the University of Nebraska-Lincoln. Data from roughly 275,000 groundwater samples in the High Plains and Central Valley aquifers show that many Americans live less than two-thirds of a mile from ...

  • Studies reveal why drinking water wells are vulnerable to contamination

    New USGS groundwater studies explain what, when, and how contaminants may reach public-supply wells. All wells are not equally vulnerable to contamination because of differences in three factors: the general chemistry of the aquifer, groundwater age, and direct paths within aquifer systems that allow water and contaminants to reach a well. More than 100 million people in the United States receive ...

  • Fertilisers linked to contaminated drinking water in Evros, Greece

    In a new study, samples of drinking water from the north-east of Greece have been found to exceed European limits for nitrates, sulphates and phosphates - chemicals that are linked to health problems such as reproductive disorders and cancer. The research has produced a map of the Evros area showing the location of 64 water sampling sites and found that pollution levels are highest in areas with ...

  • USGS report `contaminants in groundwater used for public supply` released

    The US Geological Survey (USGS) a unit of the Interior Department, has released a study of untreated water samples from 932 public wells across the nation.  Findings showed that naturally occurring contaminants, such as radon and arsenic, accounted for about three-quarters of contaminant concentrations greater than human-health benchmarks. Man-made contaminants were also found including ...

  • Aerobic cometabolism of tetrachloroethylene (PCE)

    Tetrachloroethylene (PCE) is a problem contaminant because of its widespread use, potential toxicity and persistence in the environment. Like other chlorinated solvents, remediation of PCE in soil and ground water has proven to be very difficult. While there has been has been widespread success under anaerobic conditions, the application of bioremediation under aerobic conditions has not been as ...

  • Increasing water supplies - reuse of treated wastewater

    Reusing wastewater, particularly for agricultural purposes, plays an increasingly important part in water management, particularly in areas of low rainfall. A recent study of the Apulia region in southern Italy shows that wastewater can be used to meet agricultural water needs. The Apulian water agency (AQP) runs the largest aqueduct system in Europe, importing water from neighbouring regions and ...

  • New EU study warns of significant water impacts from climate change

    The EIB and Mediterranean action group Plan Bleu have released a study on climate change, energy and water in the Mediterranean that predicts that the economic and human impacts will be significant but that improvements are possible if a sustainable approach is taken. On water resources, the report notes that these are ‘limited and very unevenly distributed over both space and time’. The southern ...

  • Study finds contaminants in California public-water supplies

    Nearly one-fifth of the raw groundwater used for public drinking water systems in California contains excessive levels of potentially toxic contaminants, according to a decade-long U.S. Geological Survey study that provides one of the first comprehensive looks at the health of California's public water supply and groundwater. One of the surprises in the study of 11,000 public supply wells ...

  • 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 ...

  • Groundwater pollution in Europe: an overview

    An overview of groundwater contaminants in Europe is provided by a recent study, which calls for more integrated monitoring using a range of indicators. Groundwater contamination presents serious health and environmental concerns. A number of Directives, including the Water Framework, Groundwater, Nitrates, Industrial Emissions and Landfill Directives, together aim to protect groundwater from ...

  • Water pollution exceeds drinking-standard limits in many OECD farming areas

    Pollution of rivers, lakes, and aquifers exceeds recommended limits for drinking water in farming areas in many OECD countries, according to a new OECD report. Environmental Performance of Agriculture in OECD Countries since 1990 shows that excess levels of nitrates, phosphorus or pesticides were found in more than one out of 10 monitoring sites in 13 OECD countries. Treating pesticide- and ...
