  • Revolutionary new meter field tests Lead, Mercury and Cadmium levels in Water

    The new eXact LEADQuick™ photometer is the ideal meter for field testing Lead, Mercury and Cadmium amounts in potable water. This new modified method accurately detects 3 to 500 µ/L (ppb) on site lead (as Pb+2) levels in either water (as low as 3 µg/L), soil (as low as 50 mg/kg) or paint (as low as 0.05 mg/cm2) with resolution of 1 µg/L and accuracy of +/-3 µg/L. The ...

  • First-of-a-kind sequestration field test begins in West Virginia

    Injection of carbon dioxide (CO2) began today in a first-of-a-kind field trial of enhanced coalbed methane recovery with simultaneous CO2 sequestration in an unmineable coal seam. The ultimate goal of the U.S. Department of Energy–sponsored project is to help mitigate climate change by providing an effective and economic means to permanently store CO2 in unmineable coal seams. CONSOL Energy ...

  • ASTM D4829 - 11 standard test method for expansion index of soils

    The expansion index, EI, provides an indication of swelling potential of a compacted soil. The EI test is not used to duplicate any particular field conditions such as soil density, water content, loading, in-place soil structure, or soil water chemistry. However, consistent test conditions are used in preparation of ...

  • ASTM D3080 / D3080M - 11 Standard Test Method for Direct Shear Test of Soils Under Consolidated Drained Conditions

    1. Scope 1.1 This test method covers the determination of the consolidated drained shear strength of a soil material in direct shear. The test is performed by deforming a specimen at a controlled strain rate on or near a single shear plane determined by the configuration of the apparatus. Generally, three or more ...

  • Soil Particle Size Distribution

    Particle size distribution, also known as gradation, refers to the proportions by dry mass of a soil distributed over specified particle-size ranges. Gradation is used to classify soils for engineering and agricultural purposes, since particle size influences how fast or slow water or other fluid moves through a soil. Two proposed new ASTM standards provide test methods for determining particle ...

  • ASTM D7202 - 11 standard test method for determination of beryllium in the workplace using field-based extraction and optical fluorescence detection

    Exposure to beryllium can cause a potentially fatal disease, and occupational exposure limits for beryllium in air and on surfaces have been established to reduce exposure risks to potentially affected workers (4, 5). Sampling and analytical methods for beryllium are needed in order to meet the challenges relating to exposure assessment and risk reduction. Field-portable sampling and ...

  • Precompression stress in soils

    The precompression stress as a factor to assess the mechanical stability of soils is predictable by using pedotransfer functions. Over the past decades arable soils have been deteriorated because of the heavy machinery on the farm. Increase loads enhance subsoil compaction which is mostly irreversible. As a consequence of this deformation, the soil productivity decreases while the erodibility ...


  • Protecting valuable urban soil

    Soil provides multiple services, ranging from food production, water-filtering and carbon capture, to green park areas in towns and cities, important for human well-being. However, increased urbanisation is leading to a loss of soil resources. Researchers have developed an online evaluation method that can be used as an aid to urban planning to avoid the loss of precious areas of good quality ...

  • Pesticide impact: comparing lab, field-scale results

    Assessing the environmental risk of pesticide use is an important, complex task that requires knowledge of the equilibrium sorption parameter. This helps researchers assess the risk of pesticides leaching into groundwater. For cost-effective assessments, this is usually determined through batch experiments that find the amount of pesticide in test soils as a function of concentration at a ...

  • Drain rice fields to cut methane, say scientists

    Global methane emissions from rice paddies could be cut by 30 per cent if fields are drained at least once during the growing season and rice crop waste is applied off-season, according to a study. Methane is a significant contributor to global warming and is produced by certain types of bacteria in oxygen-deprived environments — such as those feeding on the organic waste in water-covered ...
