  • Lower costs, fewer delays - a highway expansion project applies XRF technology to obtain cost-effective remediation.

    X-ray fluorescence (XRF) spectrometry is a non-destructive, analytical method used primarily to detect the metal composition in soil/solids samples. Portable XRF instruments can provide rapid, accurate analysis of heavy metal levels in soil on new construction or redevelopment sites. In response to the growing need for field analysis of metals, many of these units have been adapted for use in the ...

  • Soil Sampling Protocol to Certify the Changes of Organic Carbon Stock in Mineral Soils of European Union

    The Kyoto Protocol (UNFCCC, 1998) considers soils as an essential component to mitigate the increasing concentrations of greenhouse gases in the atmosphere. Two additional reports: (1) Land Use, Land-Use Change, and Forestry (LULUCF) (IPCC, 2000) and (2) Good Practice Guidance for LULUCF (IPCC, 2003) identify soil organic carbon (SOC) monitoring to be an obligatory tool when implementing Articles ...


  • Soil CO2 Flux Measurements -- Using the LI-8100 System to Collect Air Samples for Estimating Soil Trace Gas Flux

    Air samples can be collected from the same air stream used to measure soil CO2 flux with the LI-8100 Automated Soil CO2 Flux System, for estimating the flux of trace gas, such as methane (CH4), ammonia (NH3), nitrous oxide (N2O), isotopic species, etc. This application note describes a simple method for obtaining air samples from the LI- ...

  • Chemical Impregnation of Cohesionless Soils

    Existing methods to obtain and test high-quality undisturbed samples of cohesionless soil below the water table depend at some stage on freezing. This limits the range of application to relatively clean sands, and even for those soils the freezing operation is delicate, time-consuming, and costly. Moreover, there is no direct way to check, independently, the effects of the freezing process on the ...

  • Parallel Pressurized Solvent Extraction of PCDD/PCDF, PBDE, and PFC from Soil, Sludge, and Sediment Samples

    The efficacy of pressurized solvent extraction with BUCHI's new SpeedExtractor was examined for the extraction of dioxins/furans (PCDDs/PCDFs), polybrominated diphenyl ethers (PBDEs), and perfluorinated compounds (PFCs) from different environmental matrices: PCDDs/PCDFs from soil samples, PFCs from soil and sewage sludge, and PBDEs from lake sediments. The results of the extraction of PCDDs/PCDFs ...

  • Small-increment electric soil sampler

    Measurement of soil bulk density and volumetric water content in small (2-cm) depth increments is tedious and time consuming. Most methods require compositing several subsamples to control measurement error, and few are feasible with loose, dry soils. We developed and tested a sampler that uses an electric linear actuator to push an intact soil core out of the sampling tube. The soil core is ...

  • A method for measuring saturated hydraulic conductivity in Anisotropic soils

    Saturated hydraulic conductivity (Ks) is an important soil parameter that is difficult to measure, especially in an anisotropic medium. Many methods for determining Ks have been developed over time, but taking different water flow directions into consideration is possible in only a few of them; furthermore, these few methods cannot be universally applied. The method proposed here allows Ks to be ...
