  • Groundwater Atlas for pesticides

    The recently published Groundwater Atlas for pesticides provides an overview of where and when pesticides have been found in groundwater. The results can be used to improve water quality in the Netherlands. The data will be used by the Board for the Authorisation of Plant Protection Products and Biocides (Ctgb) to monitor groundwater quality. The Groundwater Atlas was developed between 2015 and ...

  • Pesticide pollution slow to reach groundwater

    Underground water aquifers are a significant source of drinking water. In a recent study, French researchers found that pesticides applied to crops can take many years to sink down through the ground and reach groundwater. This means that they may still be entering aquifers, even after agricultural application has stopped. Groundwater is found underground in absorbent layers of rock. ...

  • Pesticides persist in groundwater, say SSSA

    Numerous studies over the past four decades have established that pesticides, which are typically applied at the land surface, can move downward through the unsaturated zone to reach the water table at detectable concentrations. The downward movement of pesticide degradation products, formed in situ, can also contribute to the contamination of ground water. Once in ground water, pesticides and ...

  • EPA to fund monitoring of groundwater wells at California pesticide dump

    The U.S. Environmental Protection Agency is asking for public comment on a proposed agreement with Target Corporation to allow for redevelopment of land adjacent to the Frontier Fertilizer Superfund site. Under this agreement, Target Corporation, with EPA oversight, will fund and perform movement of eight groundwater monitoring wells at privately-owned parcels lying to the north and west of the ...

  • Mapping pesticide contamination risk

    A new computerised tool helps regulators identify water sources at risk of pesticide contamination. The tool can be used to produce maps indicating water bodies at risk of contamination by taking into account: adjacent land-use, the concentration of pesticides in the environment and biological indicators of contamination. Protection of water resources is a key priority for the EU and water bodies ...

  • EC completes pesticide review programme

    The European Commission made an important step forward in its efforts to ensure improved protection of human health and the environment, as it completed the review of existing pesticides that were on the market before 1993. This programme concerned about 1,000 substances, of which about 250 have passed the harmonised EU safety assessment. All reviewed pesticides have undergone a detailed risk ...

  • 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 ...


  • 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 ...

  • Pesticide impact: comparing lab, field-scale results

    Assessing the environmental risk of pesticide use is an important, complex task that requires knowledge of the equilibrium sorption parameter. This helps researchers assess the risk of pesticides leaching into groundwater. For cost-effective assessments, this is usually determined through batch experiments that find the amount of pesticide in test soils as a function of concentration at a ...

  • Encouraging results in evaluating groundwater contaminants

    The widespread use of pesticides across the United States has been in practice for decades, with little knowledge of the long-term effects on the nation’s groundwater. The results of a new study show that samples taken from over 300 wells across the US have not retained a high concentration of pesticide contamination. The news is a result of a decadal long study to assess the extent of the ...

  • Determining the good status of groundwater in the EU

    Groundwater standards in Member States are to be established by the end of 2008, according to the European Union's new Groundwater Directive. Recent research has developed a new method to determine the chemical status of groundwater which is applicable across the EU. This procedure has been assessed by testing the quality of the groundwater of the Upper Rhine Valley in Germany, Switzerland and ...

  • Soil microorganisms help prevent non-target effects of pesticides

    A new study has investigated the properties of different types of soils which can cause pesticides to cling on to soil and prevent them from affecting non-target species. It demonstrates that microorganisms can play an important role in binding pesticides to soil. Microbial levels can therefore help indicate how much pesticide is freely available in soil. Pesticides applied during agricultural ...

  • US drinking water and watersheds widely contaminated by hormone disrupting pesticide, Atrazine

    A widely used pesticide known to impact wildlife development and, potentially, human health has contaminated watersheds and drinking water throughout much of the United States, according to a new report released by the Natural Resources Defense Council (NRDC). Banned by the European Union, atrazine is the most commonly detected pesticide in U.S. waters and is a known endocrine disruptor, which ...

  • US Groundwater Foundation launches green sites program

    The Groundwater Guardian Green Site program for 2008 has been launched with the aim of recognizing good stewards of groundwater by encouraging managers of highly-managed green spaces to implement, measure, and document their groundwater-friendly practices. The program will document current practices related to pesticide and fertilizer use, water use, pollution prevention, water quality, and ...
