  • Water contamination detector

    A contamination event at a UK water pumping station was successfully detected by the Chelsea Technologies FASTtracka II system. The event was automatically detected using the FASTtracka II, Fast Repetition Rate (FRR) chlorophyll a fluorometer combined with a novel Red, Amber, Green (RAG) algorithm, which has been developed to provide continuous, real-time protection for water supplies at the ...


  • BTEX contamination of soil and water

    BTEX is an acronym for benzene, toluene, ethylbenzene and xylene. They are all volatile organic compounds (VOCs) found in petroleum hydrocarbons. Contamination of soil and groundwater from BTEX has occurred at petroleum and natural gas production areas, gas stations and areas with underground and above-ground storage tanks of petroleum products. The compounds are also produced in large scale by ...


  • 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 ...


  • Contamination Threatens Tucson Drinking Water

    TUCSON, Arizona, July 16, 2007 (ENS) - The U.S. Environmental Protection Agency Friday ordered the Raytheon Company and the U.S. Air Force to clean up a migrating plume of contaminated groundwater at the Tucson International Airport Area Superfund Site. Under the order, Raytheon, formerly Hughes Aircraft, and the U.S. Air Force are required to treat two solvents, trichloroethylene (TCE) and ...

  • Radioactive contaminants removed from water

    A combination of forest by-products and crustacean shells may be the key to removing radioactive materials from drinking water, according to researchers from North Carolina State University. Pawlak and fellow researchers found that the new material, which forms a solid foam, has applications beyond radioactive materials and can also remove salt from sea water. “As we’re ...


  • 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 ...

  • US drinking water contaminated by pharmaceuticals

    A vast array of pharmaceuticals - including antibiotics, anti-convulsants, mood stabilizers and sex hormones - have been found in the drinking water supplies of at least 41 million Americans, an Associated Press investigation has claimed. Water in 24 metropolitan areas, including Detroit, Louisville, southern California and Northern New Jersey is particularly at risk. The report says the ...

  • 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 experts to address contaminants found in water

    Drinking water experts will convene at the Sacramento Convention Center, February 5 and 6 for a symposium focused on inorganic contaminants found in water. The Inorganic Contaminants Symposium will feature presentations and seminars led by renowned U.S. and international experts. Topics include: new techniques for treatment and analysis of drinking water, new challenges and risk assessment ...

  • Nanostructures to facilitate the process to eliminate organic contaminants in water

    In her PhD thesis, Silvia Larumbe-Abuin has developed nanostructures that assist in the process to decontaminate water. The nanostructures (particles of a microscopic size of between 1 and 100 nanometres) are coated in titanium oxide to which nitrogen has been added. This allows sunlight, rather than ultraviolet radiation, to trigger the process involving the chemical reaction and destruction of ...

  • Emerging Contaminants: New Challenges for the Water Industry

    Over the past decade there has been growing concern regarding the presence of biologically active contaminants including endocrine disrupters, pharmaceuticals, personal care products and other substances in the aquatic environment. Emerging contaminants not only include those substances in active or past production, but also include their metabolites and other transformation products and chemical ...


  • Drinking water of 41m Americans contaminated with pharmaceuticals

    An investigation by the Associated Press (AP) has revealed that the drinking water of at least 41 million people in the United States is contaminated with pharmaceutical drugs. It has long been known that drugs are not wholly absorbed or broken down by the human body. Significant amounts of any medication taken eventually pass out of the body, primarily through the urine. 'People think that if ...

  • Texas: Can`t Tie Water Contamination to Drilling

    The amount of explosive gas tainting a North Texas neighborhood's water supply has increased in recent years, but the state's oil and gas regulator says it can't link the methane to drilling activity nearby, according to a report it released Wednesday. The state Railroad Commission has found that the contamination has gotten worse in most of the private water wells it tested in September 2013 ...

  • Shale gas extraction linked to water contamination

    A new study suggests shale gas extraction leads to methane contamination of underground water sources and calls for thorough surveys of methane levels at extraction sites. The study presents a timely insight into a relatively under-researched area of science that will help support decisions on the future of shale gas exploration. Shale gas, or natural gas extracted from sedimentary rocks ...

  • Contaminated water still troubles Japan nuke plant

    The radioactive water that has accumulated at Japan's crippled nuclear power plant remains the biggest problem hampering the cleanup process three years after the disaster. The Fukushima Dai-ichi plant has stabilized substantially since the March 11, 2011, earthquake and tsunami destroyed its power and cooling system, triggering meltdowns. Massive amounts of water are being used to cool the ...

  • Density dependant water flow and contaminant transport

    SoilVision Systems Ltd. would like to announce the release of the addition of fully coupled density-dependent water flow and contaminant transport in ChemFlux and SVFlux. Using the new density-dependent flow capability can improve the accuracy of the simulation of heavy salt water. This new feature has been implemented in 1D, 2D, and 3D models and is enabled to work with the Professional version ...


  • Contaminants monitored for safe drinking water act

    As part of its commitment to implement sensible protections of drinking water for communities across the country, and as required by the Safe Drinking Water Act, the US Environmental Protection Agency (EPA) is proposing thirty currently unregulated contaminants for monitoring in water systems, and submitting this proposal for public comment. The comment period will allow the public and other ...


  • Low health risk from contaminated flood water

    Residents in flood-affected areas have been advised to take sensible precautions as the flooding subsides but have been reassured that there is only a small chance of picking up an infection from contaminated water.   The independent ...

  • Contamination concern grows over private water supplies

    Water supply specialists are urging farmers to monitor their private water supply for possible contamination now that flood waters have receded.  Flood water in a private water supply can cause increased susceptibility to iron related bacteria as well as stimulate bacterial activity if it is already present. Iron bacteria is one of the most common contamination problems in private water ...
