  • 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, ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Train derailment prompts contaminated land investigation

    On March 30th 2015 a long freight train, transporting a variety of goods including lumber and chemicals, wound its way through the state of Mississippi. At around 5pm, part of the train failed to negotiate a curved portion of the track in a rural area near Minter City, resulting in the derailment of nine railcars, one of which leaked chemicals onto agricultural farmland and woodlands. Emergency ...

  • 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 ...

  • 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 ...

  • Floodway Chemical, Pesticide Contamination below levels of health concern

    Detailed analysis of the May 24 limited sampling of floodwaters in the Birds Point-New Madrid Floodway in southeast Missouri found contamination at levels typically found in the Mississippi River in nine samples of collected water. The samples are also below levels of health concern for those involved with continuing cleanup activities. Previous results had indicated the presence of E. coli ...

  • Hurricane Sandy May Cause Sewage Contamination after Floods

    Although Hurricane Sandy has officially passed, many on the East Coast continue to feel the effects. Every East Coast state, from North Carolina to Massachusetts and as far in land as Michigan, experienced flooding, and an estimated eight million were without power as of Tuesday. In areas where extreme flooding occurs, sewage contamination usually follows. Environmental sewage contaminations not ...

  • 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 ...

  • Industrial Hygiene Publication Highlights Mycometer’s Surface and Air Sampling Technologies
