  • Landfill Liners Vary by Application

    It was in 1991 that the Environmental Protection Agency promulgated its Criteria for Municipal Waste Landfills that set location restrictions, design and operating standards, groundwater monitoring requirements, corrective actions, closure requirements, and more for landfills. It was these rules that mandated that landfills be lined on the sides and bottom before waste is deposited and capped on ...

  • Evaluation of geomembrane, amended soil and composite liner system as lining materials for chromium decontamination in landfill site

    A comprehensive laboratory and field–scale study was performed to explore the efficacies of geomembrane, amended soil liner material and composite liner packs for using as containment liner systems for attenuating chromium transport emanating from a chrome laden solid waste disposal site. Soil samples were collected from the site and were admixed with different amended materials, such as rice ...

  • Assessing Frost Damage in Compacted Clay Liners

    Methods used to assess frost damage (here defined as a large increase in hydraulic conductivity) in compacted clay liners are reviewed and evaluated using data collected from two test pads that were instrumented and then exposed to winter weather. The methods include comparisons of measurements of either water content and dry unit weight or hydraulic conductivity made before and after winter ...

  • Pollution level detection in dump clay liners by hyperspectral imaging

    Landfill is the most common and cost–effective method of waste disposal, with collection and transportation accounting for 75% of the total cost. A key point in waste disposal is the picking up and the drainage of percolation fluids to limit the risk of groundwater contamination. Aim of this study was to evaluate the possibility to develop fast and reliable methods to perform an in situ ...

  • Hydraulic conductivity of residual lateritic soil permeated with organic chemicals

    In this study, three lateritic soil samples compacted at 2% wet of optimum moisture content with British Standard Light (BSL) effort were permeated with acetone and ethanol over a range of concentrations (0, 25, 50, 75, 100%), while benzene and heptane were used at full strength. Hydraulic conductivity of specimens permeated with diluted solutions of acetone and ethanol ( ...

  • Compatibility of compacted lateritic soil treated with bagasse ash and Municipal Solid Waste leachate

    Compatibility tests were carried out on lateritic soil treated with up to 12% bagasse ash compacted at about 2% wet of their respective optimum moistures using the standard Proctor energy. Samples were sequentially permeated with distilled water and municipal solid waste (MSW) leachate for 22 and 69 days, respectively, until steady flows were established. The final hydraulic conductivity values ...

  • Detection of chlordane in water

    MATRIX: Water (surface, ground and drinking) ANALYTE: Chlordane RANGE OF DETECTION: 2.0 to 60.0 ppb MATERIALS: EnviroGard Chlordane in Soil Test Kit (Item #73110) Methanol (pesticide grade) Glass vials with teflon lines caps PROCEDURAL NOTES: Water samples should be collected in glass ...


  • Petrol and heating oil bioremediation using EU70 (case study)

    As a result of an accident a tanker lost its load of petrol and heating fuel. A large quantity of fuel approximately 2000 litres soaked into the soil. Analyses revealed that the average level of hydrocarbons present was in the order of 0.55 %. The pollution affected an area of 100 m2 and to a depth of 0.6 m. Our goal was to reduce hydrocarbon levels to the lowest possible value in order to ...

    MATRIX: Water (surface, ground and drinking) ANALYTE: DDT RANGE OF DETECTION: 10 to 500 ppb MATERIALS: EnviroGard DDT in Soil Test Kit (Item #73100). Methanol (pesticide grade). Glass vials with teflon lines caps. PROCEDURAL NOTES: Water samples should be collected in glass vessels with teflon cap ...


  • Biopiles

    Biopile treatment is a full-scale technology in which excavated soils are mixed with soil amendments and placed on a treatment area that includes leachate collection systems and some form of aeration. It is used to reduce concentrations of petroleum constituents in excavated soils through the use of biodegradation. Moisture, heat, nutrients, oxygen, and pH can be controlled to enhance ...

  • Solar energy landfill caps

    Things weren’t going well at the Erewhon Landfill. It was time to close the facility, and there was no soil left onsite for construction of the cap. Erewhon was a County facility, and the money available for 30 years of post-closure gas monitoring, groundwater sampling and reporting, erosion repairs and maintenance of a grass cover was sorely needed elsewhere. The landfill manager recalled ...

  • Sustainable, Low-maintenance Disinfection for Onsite Systems

    Most of the regulations applicable for onsite wastewater treatment system are based on the use of native soil for effluent dispersal. However, there are more and more situations where dispersal of effluent in native soil is impossible: repairs of existing systems on undersized lots for implementation of required dispersal fields: sites located in soils having low permeability: or where the ...

  • Bioremediation of an Oil Spill

    Bioremediation is the method of choice to effectively clean up a small spill of hydrocarbons. In this case, five-hundred liters of BTEX has spilled from an above ground storage tank into a pasture that is located at the west edge of the Royal Roads University (RRU) grounds. The soil is classified as a Gleyed Eutric Brunisol based on recent laboratory analysis; it contains clay, but is fairly ...


  • Ontario Regions Invest In Residential Organics Diversion

    The Regions of Peel and Durham have distributed bins and kitchen containers for source separated organics to 460,000 households to receive weekly curbside collection. Starting April 2nd, residents in Caledon, Brampton and Mississauga, Ontario - all in the Region of Peel - began setting out kitchen waste and soiled paper at the curbside for weekly collection. Between February and March, more ...

  • Taking Geosynthetics CQA To - New Heights - Case Study

    For years, the geosynthetics Construction Quality Assurance (CQA) industry has struggled to find a cost-effective, accurate, and sustainable solution to data collection, validation and review. Since the inception of geosynthetics CQA, the challenge with CQA has been to obtain all the required data in a logical, efficient and error free manner while insuring that the project construction and data ...

  • Composting releases less air pollution than previously thought - study

    A new study funded by the California Integrated Waste Board (CIWMB) indicates that well-managed composting of green waste and food waste releases significantly less air pollution than previously thought. The study also demonstrates that a relatively inexpensive management technique - covering active compost piles with a layer of finished compost - may lower air emissions even further, by as ...

  • Source separated residential composting in the US

    THE Field of Dreams movie theme, “if you build it they will come,” is definitely à propos to source separated residential organics composting. While conducting this year's survey, we asked program managers what they think the key ingredients are to offering households the ability to divert more than just yard trimmings at the curb - a practice that is widely adopted in some Canadian provinces and ...
