  • Monitoring and Treatment of Selected Nanoparticles

    With their increasing use, nanoparticles will become concentrated in urban effluents in the future. Both adequate monitoring methods and water treatment technologies will be necessary to assess and avoid consumer exposure. This paper reports results in these two challenging areas for both organic and inorganic nanoparticles. Treatment experiments indicate that lamellar settling is better adapted ...

  • Nanotechnology Briefing Paper Clean Water Act

    The purpose of this briefing paper is to evaluate the existing statutory authority under the Clean Water Act (CWA or Act) to regulate nanotechnology and nanoparticles.2 One of the stated national goals of the CWA is the elimination of the discharge of pollutants into the navigable waters. Accordingly, the CWA generally provides the U.S. Environmental Protection Agency (EPA) with authority to ...

  • IEG multi level sampling well (MLSW) case study - IEG Technologie GmbH

    The MLSW-system is used for the recovery of multiple high-quality samples of soil-gas and groundwater from numerous isolated horizons in a single standard borehole. The system is also used to accurately delineate contamination profiles in three dimensions, which is vital or the design, installation and monitoring of remediation systems. MLSWs also can be used for activly dispersing substances ...

  • Spolchemie site remediation and NanoRem field site application

    Site Remediation The Spolchemie site was chosen as one of the NanoRem case study sites, to test two types of nanoparticles (NPs) (zerovalent iron - nZVI and iron oxide NPs) for in situ remediation of BTEX (Benzene, Toluene, Ethylbenzene, and Xylenes) contamination. Nanoremediation was seen as an opportunity to enhance the in situ biodegradation of the BTEX contaminants and to reduce the ...

  • New EU RoHS finally here – significant changes for EEE on the horizon

    After three years of debate, the revised RoHS Directive (65/2011/EU) has finally been adopted by the European Parliament and the Council resulting in significant changes  for electrical and electronic equipment. In 2008, the European Commission launched the review of the related directives of WEEE, addressing  the collection and recycling of electrical and electronic equipment (EEE), ...

  • Tiny materials in countless products raise big questions for environment and health

    Nanotechnology opens a universe of possibilities — but also creates a world of unknowns. In recent years, efforts to develop the Next Big Thing — whether in medicine, computer technology, pollution prevention or high-performance materials — have turned to some really, really small things: nanomaterials. Working at the ...

  • Reaching underground resources

    Accessing critical resources such as geothermal energy and natural gas requires drilling — an expensive, energy-intensive, messy process with today's technology. An MIT team has been looking into a more elegant approach. Instead of grinding rock to bits, they would use a continuous beam of energy to vaporize it and then blow out the tiny particles that form with a high-pressure stream of ...
