  • Fast bioremediation of a hydrocarbon contaminated site

    The use of bioremediation has been demonstrated to be a very effective treatment technology for a hydrocarbon contaminated site within a month of starting. In addition to selection and preparation of an appropriate microbial inoculum the other key considerations were effective mixing, addition of suitable nutrients and maintenance of soil moisture levels. Careful management of all these ...

  • Getting ahead of the Caribou - pitdry process—innovative solidification solution for spent drilling fluids

    An oil company has been producing oil and gas in British Columbia’s Southern Foothills since 1992. The operator has continuously invested in the area and recently opened up new gas producing wells northwest of Fort St John, the largest city in the northeast region of British Columbia. The new wells are situated 4,600 feet above sea level in a rigid mountain terrain. The viable way to connect the ...

  • London 2012: Legacy or Liability?

    After spending hundreds of millions of tax payers’ money on a high profile ‘clean-up’, it has become clear that the 2012 Olympic Park actually remains classified as a contaminated brownfield site. Documents show that the whole area is to have as little as 2 feet (60cm) of “clean” material placed on top of a warning marker layer of orange plastic fabric sheeting, of a type called Terram 1000, ...

  • Compacted lateritic soil treated with blast furnace slag as hydraulic barriers in waste containment systems

    Laboratory testing was conducted to assess the feasibility of using lateritic soil mixed with up to 15% blast furnace slag (BFS) by dry weight of soil as a suitable hydraulic barrier. Tests were carried out on the lateritic soil-slag mixture to ascertain the particle size distribution, index properties and compaction characteristics. The relationship between hydraulic conductivity, unconfined ...

  • Bioremediation of soil

    In our experience, Bioremediation is best accomplished with Bio-augmentation, the addition of large numbers of selected micro-organisms grown in the production laboratory. In addition to bio-augmentation, several physical and chemical parameters must be controlled in order to obtain optimal growth and maximum degradation of soil contaminants. The major factors that are controlled during ...

  • Field-scale cleanup of atrazine and cyanazine contaminated soil with a combined chemical-biological approach

    A former agrichemical dealership in western Nebraska was suspected of having contaminated soil. Our objective was to characterize and remediate the contaminated site by a combined chemical-biological approach. This was accomplished by creating contour maps of the on-site contamination, placing the top 60 cm of contaminated soil in windrows and mixing with a mechanical high-speed mixer. ...

  • Zn and Cd hyperaccumulating characteristics of Picris divaricata Vant.

    A field investigation and a pot experiment were conducted to study the Zn and Cd accumulation in Picris divaricata Vant. Under natural conditions, the average Zn and Cd concentrations in shoot of P. divaricata were 5911 and 246 µg g−1 (DW), with the maxima of 18,339 and 585 µg g−1, respectively. Grown on a mixed soil for three months, P. divaricata accumulated up to 15,183 μg g−1 Zn and 364 µg ...

  • Recreating a functioning forest soil in reclaimed oil sands in Northern Alberta: an approach for measuring success in ecological restoration

    During oil-sands mining all vegetation, soil, overburden, and oil sand is removed, leaving pits several kilometers wide and up to 100 m deep. These pits are reclaimed through a variety of treatments using subsoil or a mixed peat-mineral soil cap. Using nonmetric multidimensional scaling and cluster analysis of measurements of ecosystem function, reclamation treatments of several age classes were ...

  • Sampling moisture in the soil profile

    Patterns of water replenishment and use give rise to large spatial variations in soil moisture over the depth of the soil profile. Accurate measurements of profile water content are therefore the basis of any water budget study. When monitored accurately, profile measurements show the rates of water use, amounts of deep percolation, and amounts of water stored for plant use.Experimental ...

  • New ground ripe for foundry sands

    The US foundry industry uses around 100 million tons of sand each year to produce metal castings. Although the sand is recycled inside the casting process, about 10 percent of the sand is discarded and potentially could be utilized in commercial soil blending operations. Currently only around a million tons of that sand is recycled; the remaining 8-12 million tons are landfilled, according to the ...

  • Soil baked to clean up contamination...

    Can an old drill site be cleaned up without adding truckloads of contaminated soil to the landfill? Chevron Canada will be using a technology called thermal desorption to clean up a site located 13 kilometres southwest of Pincher Creek. Leif Sollid, spokesman for Chevron, who is the operator of the site, said they considered two options for the clean up. The soil is classified as a non-dangerous ...

  • Compost in the mix for storm water management

    Bioretention areas, also known as rain gardens, are increasingly being used to capture and treat storm water runoff from impervious surfaces such as roofs, sidewalks and parking lots. These landscaped areas often feature native plants installed in an engineered soil mixture that includes compost. “Bioretention areas or rain gardens are an attractive storm water Best Management Practice (BMP) ...

  • Charcoal distribution affects Carbon and Nitrogen contents in forest soils of California

    Fire is the dominant natural disturbance regime in most ecosystems of California. The long-term relict of fire is charcoal, which has been shown to increase N mineralization and also represents a pool of chemically stabilized C whose quantity and spatial distribution have not been well characterized in forest soils. We examined the charcoal content in three different ecosystems of the Sierra ...
