  • New monitoring tools for petrol additive MTBE in groundwater

    Methyl tertiary-butyl ether (MTBE) is a petrol additive which can contaminate groundwater supplies. MTBE often breaks down naturally in the environment, but regulators need to be certain that this is taking place. New research highlights a number of tools in development that may offer better data on spilled MTBE in the environment, and improve the ability to monitor its degradation. MTBE is added ...

  • Gasoline additive MTBE widespread in New Hampshire’s groundwater

    The gasoline additive methyl tert-butyl ether (MTBE) is widespread in New Hampshire's ground water, particularly in four counties -- Rockingham, Strafford, Hillsborough and Merrimack. Ground water from these counties was more likely to contain MTBE than were samples from the rest of the state. Across the state, however, the MTBE concentrations were significantly below the state drinking water ...

  • EPA Determination on 11 Contaminants

    The U.S. EPA has made a preliminary determination not to regulate 11 contaminants on the second drinking water contaminant candidate list (CCL). The agency?s preliminary regulatory determination, based on an extensive review of health effects and occurrence data, concludes that the specific contaminants do not occur at levels of public health concern in public water systems. 'We are confident ...

  • Rhodococcus bacteria can help clean up fuel-contaminated sites

    Fuel spillages and leaks from petroleum storage facilities can lead to serious pollution of soils and underground water. In a recent study, two strains of Rhodococcus bacteria were found to be effective at degrading a number of petroleum hydrocarbons and thus helping clean up contaminated sites. Fuels can be significant pollutants of soils and groundwater, especially around fuel storage ...

  • Court upholds $236M verdict in Exxon Mobil pollution case

    New Hampshire's highest court upheld a record $236 million judgment Friday against Exxon Mobil for its use of a gasoline additive that contaminated groundwater in the state. A jury reached the verdict in April 2013 after finding the company liable in a long-running lawsuit over contamination by the chemical MTBE. Lasting nearly four months, the trial was the longest and resulted in the largest ...
