  • Environmental sound barriers: a mixed blessing

    Busy roads have major impacts on the environment of surrounding areas, with noise pollution from traffic being one of the biggest problems. Building sound barriers alongside the road is a common way to minimise such noise. A recent study highlights the benefits and disadvantages of sound barriers. Earth mounds, fences or walls are frequently constructed as sound barriers alongside busy roads and ...

  • BAUER Maschinen GmbH and RTG Rammtechnik GmbH introduce new soil mixing tool (SCM-DH)

    Different soil mixing techniques have been in operation for many years. When mixing cement slurry into loose or soft, non-load-bearing subsoil, the load-bearing capacity of the subsoil increases and the settlement is reduced. For this purpose, the BAUER Group offers several types of equipment and processes which are also suitable for the construction of cut-off and load-bearing retaining walls ...

  • MIXED IN-SITU & EX-SITU PROJECT SUCCESS

    Envirotreat Ltd have recently undertaken remedial works at an operating gas governor station to the north of Manchester (UK), that had previously used as a full gas production facility. The voluntary remediation project formed part of the comprehensive programme being undertaken by the Client at a number of old gas production sites across the North West of England. The first phase of the ...


  • Automated Soil pH Analysis

    MANTECH (Canada) a manufacturer of automated multi-parameter, titration, COD and BOD analyzers has recently installed a number of automated soil pH analyzers around the globe. Laboratories with demanding requirements came to MANTECH with the need for a durable and rugged solution to measure soil pH for difficult samples. The nature of these samples required complex sample preparation, timing and ...

  • Absorbing organic pollutants in soils

    A new study closely examines the role degrading plant materials play in absorbing organic pollutants in the soil. These “biopolymers” are the waxy, water resistant barriers between the plant cells and the environment. This information is important to evaluate the role of these biopolymers as a natural sorbent for organic pollutants in the environment. The study, reported in the ...

  • Oil and water don’t mix – but can they co-exist?

    Real progress is being made to reduce the environmental impact of oil sands activities. But that message is being lost in the flood of bad press about contamination of adjacent waterways and concerns about those ugly tailings ponds. Oil and water don't mix. But can they co-exist? August has not been a good month for the Alberta oil sands industry. The tidal wave of bad news that flooded the media ...

  • Predicting amount of oil in contaminated soils

    Scientists are reporting a new technique for mapping and testing oil-contaminated soils. Traditionally, samples need to be collected from the field and returned to a lab for extensive chemical analysis, costing time and money when neither is readily available during a clean-up operation. The new method can take measurements in the field and accurately predict the total amount of petroleum ...

  • Free Soil Testing For Accurate Fertiliser Application

    With the growing season nearly upon us, Welsh farmers are being given an opportunity to discover the benefits of soil analysis through a number of free soil testing workshops at Farming Connect. Regular soil testing enables farmers to adopt a targeted approach to fertiliser use, thus providing significant cost savings, according to Lisa Roberts of Farming Connect. Soil analysis also identifies ...

  • Soil Association response to Defra on food security in the UK

    In response to a Defra discussion paper titled, “Ensuring the UK’s food security in a changing world”, Patrick Holden, Soil Association director, said: “Credit to Hilary Benn for joining the debate that has been live amongst far-sighted individuals and food and farming groups for years. But the dead-hand of the Treasury is still visible on the document – with its outdated economic mantra of ...

  • Silver nanoparticles in sewage sludge harmful to soil microorganisms

    Recent research has found that silver nanoparticles in sewage sludge, which is used on agricultural land as a fertiliser, can be toxic to soil microorganisms. The researchers calculated that a maximum of 30mg of silver nanoparticles per kilogram of sludge can be applied to land before harm occurs, based on typical application rates in Germany of five tons per hectare of farmland every three ...

  • Willow trees are cost-efficient cleaners of contaminated soil

    Using broad-leaved trees such as willow trees in the phytoremediation of contaminated soils constitutes a cost-efficient method for restoring mining areas and landfills, according to a research project led by the University of Eastern Finland. Funded by the EU, the project studied willow tree growth in contaminated soils in Finland and Russia. "This is a cost-efficient solution for ...


  • New reference material for hexavalent chromium in contaminated soil

    The National Institute of Standards and Technology (NIST) has issued a new standard—a certified reference material—to aid in the detection and measurement of the potent carcinogen hexavalent chromium in soil. Developed in collaboration with the Environmental Protection Agency (EPA) and the New Jersey Department of Environmental Protection (NJDEP), the new reference material will provide a crucial ...

  • Healthy soil is essential for a biobased & circular economy

    The soil is the ground beneath our feet and the growth place for biomass. For a biobased & circular economy it is crucial to preserve this ‘pantry’ storage function of the soil. This is why Wageningen University & Research is performing dedicated research into various aspects of the soil, such as nutrients and organic material, smarter cultivation systems of a larger diversity ...

  • Shifts in soil bacteria linked to wetland restoration success

    A new study led by Duke University researchers finds that restoring degraded wetlands -- especially those that had been converted into farm fields -- actually decreases their soil bacterial diversity. But that’s a good thing, say the study’s authors, because it marks a return to the wetland soils’ natural conditions.“It sounds counter-intuitive, but our study shows that in restored wetlands, ...

  • Basin wetlands checked for acid sulfate soils

    More than 1000 wetlands throughout the Murray-Darling Basin are being assessed to determine the risk posed to them by acid sulfate soils, the Murray-Darling Basin Commission (MDBC) announced today. Chief Executive Dr Wendy Craik AM said the MDBC was funding the project which is being carried out by State agencies, the Murray-Darling Freshwater Research Centre, CSIRO, Southern Cross University and ...

  • Hanford tank may be leaking waste into soil

    An underground tank holding some of the worst radioactive waste at the nation's most contaminated nuclear site might be leaking into the soil. The U.S. Energy Department said workers at Washington state's Hanford Nuclear Reservation detected higher radioactivity levels under tank AY-102 during a routine inspection Thursday. Spokeswoman Lori ...

  • Soil microbes hold key to climate puzzle

     Climate scientists puzzled by the traffic of carbon between soil and air may have to think more deeply about the role played by soil microbes − the planet’s smallest inhabitants. One research team has just found that soil microbes could actually lighten the colour of arid land soils, to  ...

  • Water hits and sticks: findings challenge a century of assumptions about soil hydrology

    Researchers have discovered that some of the most fundamental assumptions about how water moves through soil in a seasonally dry climate such as the Pacific Northwest are incorrect -- and that a century of research based on those assumptions will have to be reconsidered. A new study by scientists from Oregon State University and the Environmental Protection Agency showed -- much to the surprise ...

  • Proposed New Zealand environmental standard for assessing and managing contaminants in soil

    The New Zealand Government is proposing to introduce a National Environmental Standard for Assessing and Managing Contaminants in Soil. A proposed standard was notified on 6 February for consultation.
