  • 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 ...

  • Evaluation NUVIA process to map radiological contaminations

    The evaluation has demonstrated that Kartotrak can provide key information to a project manager for a better risk management. After several technical exchanges between NUVIA Process and Geovariances about the use of geostatistics for radiologically contaminated soil characterization, a guided evaluation was conducted to try Kartotrak on a real dataset. The first ...

  • Mapping human health risk in urban environments

    A new study demonstrates how mapping software can be used to analyse data on heavy metal soil pollution in an urban environment. The researchers incorporated land use information to gain realistic estimates of potential risks to human health that could help inform land use planning. Human activities, including industrial manufacturing and road travel, contaminate the soil with heavy metals such ...

  • Genes and GPS used to map spread of typhoid

    A combination of geographic and genetic data is showing how typhoid fever spreads, and could be used for mapping other disease patterns, a study has reported. Researchers used DNA sequencing, global positioning system (GPS) and Google Earth technologies to track typhoid transmission in Kathmandu, the rapidly growing capital city of Nepal, where thousands fall ill with typhoid fever each year. ...

  • Vermont mapping software wins national EPA award

    A computer mapping program that lets you calculate your carbon footprint and that was developed by a company in Shelburne, Vt., was recently recognized in a national challenge by the US Environmental Protection Agency. Hootroot, developed by Brighter Planet, was given the overall runner-up award in EPA’s Apps for the Environment challenge, which encourages the development of innovative ...

  • Earthwatch Puts Clean Water on the Map in Africa

    Oxford - Scientists and volunteers from Earthwatch, the environmental charity, have developed a comprehensive new Geographic Information Systems (GIS) database that will help local communities in the Samburu region of Kenya to manage their water supply and avert public health crises. Compiled over three years, the maps detail permanent and temporary water sources, including springs, rivers, ...

  • Identifying areas at risk for arsenic contamination

    The contamination of groundwater with arsenic poses a risk to the health of millions of people, especially in the densely populated river deltas of Southeast Asia. To date, no method has been available for identifying high-risk areas without conducting costly sampling campaigns. Now, Eawag has developed a model that allows vulnerable areas to be pinpointed using existing data on geology and soil ...

  • Predicting amount of oil in contaminated soils

    Scientists are reporting a new technique for mapping and testing oil-contaminated soils. Traditionally, samples need to be collected from the field and returned to a lab for extensive chemical analysis, costing time and money when neither is readily available during a clean-up operation. The new method can take measurements in the field and accurately predict the total amount of petroleum ...

  • Cholera outbreaks blamed on contaminated water

    Recurrent outbreaks of cholera in the western province of Nyanza are caused by widespread water contamination, including seepage from latrines, health officials said. 'The major contributor to the recent outbreaks in the area was unsafe water,' Shahnaaz Sharif, the senior deputy director of medical services in Kenya's health ministry, said. 'In Kisumu, many wells are built near the latrine; ...

  • Drinking water wells 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 ...

  • EPA Unveils Calif. Mapping Tool for Developing Renewable Energy Sources

    The U.S. Environmental Protection Agency, in partnership with the U.S. Department of Energy’s National Renewable Energy Laboratory, announced an online mapping tool that enables users to find contaminated and degraded properties in California ideal for renewable energy redevelopment. The Renewable Energy Siting Tool, funded by EPA, screens approximately 11,000 contaminated, degraded or ...

  • Study maps pollution’s pathway to the Arctic, sets path for future research

    MIT researchers have built a model that will be further developed as part of an NSF-funded project to track how chemicals get to remote Arctic environments. Written by Vicki Ekstrom. You can read the original story in MIT News It's been more than a decade ...

  • EPA Releases Online Mapping Tool to Help Protect Drinking Water Sources

    The U.S. Environmental Protection Agency today released DWMAPS – the Drinking Water Mapping Application to Protect Source Waters. This robust, online mapping tool provides the public, water system operators, state programs, and federal agencies with critical information to help them safeguard the sources of America’s drinking water. DWMAPS allows users to learn about their watershed ...

  • Customer uses Sitelab to test LNAPL to map plume of subsurface oil

    Are you managing petroleum sites with subsurface plumes of non-aqueous phase liquids (NAPL) at an oil refinery, fuel storage site, military base or Brownfield site? If so, use Sitelab's oil forensics field screening application for testing NAPLs for their diesel range and gasoline range content. This case study illustrates a one-day site investigation on a 30-acre tank farm site where 40 ...

  • Trio of Documents Provides the First Comprehensive Road Map for Cleaner Cleanups

    The Sustainable Remediation Forum (SURF) has issued three key guidance documents that set the stage for the future of environmental cleanup. The documents comprise a comprehensive road map for sustainable remediation – a movement to encourage cleanup projects that remove potentially dangerous contaminants from the environment while limiting external impacts and minimizing the use of energy, ...

  • Risk map shows European ‘hot spots’ for pharmaceuticals in the environment

    A new tool has been developed which highlights ‘hot spots’ of pharmaceutical pollution in Europe, where human health and aquatic environments could potentially be affected. The results suggest that the substances and locations posing the greatest risk are not the same for the aquatic environment as for human health. Both the pharmaceuticals we consume, and those that we ...

  • Shipping oil pollution: new hazard mapping method developed

    A new method for mapping the spread of oil released by ships is presented in a recent study, where it is applied to the Adriatic and Ionian Seas of the Mediterranean. The method pulls together a range of data, including information on shipping routes, oil particle behaviour, currents and climate. In this case study, it reveals pollution hotspots in the south-western Adriatic Sea and north-eastern ...

  • New hazardous waste research shows map of a growing market

    In 2007 the amount of hazardous waste that was collected and treated in Europe accounted to 67.6 million tonnes. It represents only a small percent of the total waste generated. However, its toxicity, technical/infrastructure expertise needed to handle them and the harmful impact it could have on the environment have made hazardous waste a cause of concern. Most of the European countries have ...
