  • Survey detects contamination on proposed waste disposal site

    Two small areas of radioactive contamination have been detected during a survey of grazing land adjacent to the former nuclear research site at Dounreay. They were excavated and removed to the site for analysis. One was identified as a 'minor' particle of fast reactor fuel and the other as soil contaminated with radioactivity. The finds were 5-30cm below the surface and covered by vegetation, ...

  • Improved cholera toxin detection

    With cholera on the rampage in Haiti and almost 40 other countries, scientists have reported the development of a key advancement that could provide a fast, simple test to detect the toxin which causes the disease. Details are published in the American Chemical Society’s journal Bioconjugate Chemistry.Cholera affects more than 200,000 people annually, mainly in developing countries, and ...


  • 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 ...

  • PFOS not widespread contaminant of drinking water

    Although limited data exists on perfluorinated chemicals in water, a recent study published in CIWEM’s Water and Environment Journal has found that perfluorooctane sulphonate (PFOS) is not a widespread contaminant of drinking water in England. PFOS has a number of industrial and commercial uses, including as a surfactant for fire-fighting foam, a mist suppressant for metal-plating baths and ...


  • 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 ...

  • 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 ...


  • Analysis of produced water contaminants by ion chromatography

    Drilling for oil or gas holds many challenges. Keeping pipes free of scale deposits is one of them. This involves the monitoring of ionic components in produced water, a task that is best handled by ion chromatography (IC).Avoid clogging of your pipe systemProduced water is water trapped in underground reservoir rocks and is brought to surface along with the crude oil and gas. Besides dispersed ...

  • Real-time detection of PETN explosive with PTR-MS

    The recent terror plot to transport printers containing the explosive pentaerythritol tetranitrate, or PETN, from Yemen to Chicago synagogues has once again focused attention on the need to detect explosives reliably and in real-time. PETN is the same explosive that the so-called “shoe-bomber” tried to set-off on an American Airlines jet to Miami in 2001.  More recently PETN was ...

Featuring dual-wavelength IR sensor technology in a rugged 316 stainless steel package, IRmax is designed to detect methane gas and other potentially explosive hydrocarbons in the harshest conditions. Unlike conventional IR gas detectors, IRmax does not ...

  • Mercury Hotspots Detected in Eastern U.S. and Canada

    WASHINGTON, DC (ENS) – U.S. sources of mercury emissions, particularly coal-fired power plants, are the major cause of five biological mercury hotspots identified in New England, New York and Nova Scotia, according to two new scientific studies. The findings indicate the U.S. Environmental Protection Agency, EPA, is greatly underestimating local and regional impacts of mercury ...

  • Using lasers to detect explosives and hazardous waste

    A soldier in a humvee aims a portable device at an abandoned car 50 meters away (more than 150 feet). Pressing a button, a laser in the device fires. She reads a screen, and beckons her patrol to move away quickly. In a lab, a technician is inserting a fragment of a toy into a sample case, inserting it into a machine, and pressing a button. He inserts one fragment after another—each test takes ...
