  • Earthquakes continue for years after gas field wastewater injection stops, study finds
    on February 13, 2018 at 7:58 pm

    Shutting down oil and gas wastewater injection wells may not stop human-induced earthquakes quickly, say seismologists. The scientists analyzed earthquakes at DFW Airport that began in 2008 and found that even though wastewater injection was halted after a year, earthquakes continued for at least seven more years. They concluded that high-volume injection, even for a short time, can induce long-lasting seismicity when it's near a critically stressed fault. […]

  • Small gold mines in Senegal create high mercury contamination
    on February 9, 2018 at 3:06 pm

    A new study has found high levels of mercury and methylmercury in soils, sediments and rivers near artisanal gold mines in Senegal. Nearly every sample collected from four mining villages contained mercury levels at least ten times higher than World Health Organization and U.S. Environmental Protection Agency standards. […]

  • Biotechnologists look to bacteria in extremely cold environments for 'green' detergents
    on February 7, 2018 at 5:06 pm

    Despite subzero temperatures, increased UV radiation, little liquid water, and few available nutrients, bacteria living at Earth's poles thrive. They manage it thanks in part to molecules called biosurfactants, which help them separate the complex substrates they feed on into easy-to-metabolize droplets. Researchers now review the hypothetical uses of these cold-loving molecules for 'green' detergents, fuel additives, and other applications. […]

  • Tracking wastewater's path to wells, groundwater
    on January 24, 2018 at 1:56 pm

    We often 'flush it and forget it' when it comes to waste from toilets and sinks. However, it's important to be able to track this wastewater to ensure it doesn't end up in unwanted places. Tracing where this water ends up is hard to measure: What's something found in all wastewater that will allow us to account for all of it? The answer, of all things, is artificial sweeteners. […]

  • Use of dirty heating oil in New York City concentrated uptown
    on January 22, 2018 at 8:08 pm

    Residential buildings that continued to burn residual fuel oil were concentrated in Northern Manhattan and the Bronx, as of late 2015. Compared to cleaner heating sources such as natural gas, these dirty fuels produce high levels of particulate matter, exposure to which is linked to asthma, obesity, developmental delays, and other health problems.

  • The scent of the city
    on January 22, 2018 at 8:07 pm

    In a new study, researchers present the world's first chemical fingerprint of urban emission sources of volatile organic compounds (VOCs). Accordingly, the abatement strategy for organic solvents is having an effect in Europe. At the same time, the data suggest that the total amount of human-made VOCs globally is likely to be significantly higher than previously assumed. […]

  • Bio-renewable process could help ‘green’ plastic
    on January 21, 2018 at 3:34 pm

    Plastics are often derived from petroleum, contributing to reliance on fossil fuels and driving harmful greenhouse gas emissions. To change that, scientists are trying to take the pliable nature of plastic in another direction, developing new and renewable ways of creating plastics from biomass. […]

  • Radioactivity from oil and gas wastewater persists in Pennsylvania stream sediments
    on January 19, 2018 at 7:11 pm

    More than seven years after Pennsylvania officials requested that the disposal of radium-laden fracking wastewater into surface waters be restricted, a new study finds that high levels of radioactivity persist in stream sediments at three disposal sites. Radioactivity at these sites is 650 times higher than at unaffected sites upstream. The contamination comes from conventional, or non-fracked, oil and gas wastewater, which, under current state regulations, can still be treated and discharged into streams. […]
