  • 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 ...

  • The Role of Flow Velocity in the Vertical Distribution of Particulate Organic Matter on Moss-covered Travertine Barriers of the Plitvice Lakes (Croatia)

    We investigated the distribution patterns of particulate organic matter (POM) on travertine barriers in respect to flow velocity. Research was conducted on the barrage-lake system of the Plitvice Lakes, Croatia. Four layers were distinguished within the substrate (moss mat + three travertine layers) in three hydraulic habitats at three sites. Substrate samples were collected monthly with a core ...

  • Assessment of Nitrification Potential in Ground Water Using Short Term, Single-Well Injection Experiments

    Abstract  Nitrification was measured within a sand and gravel aquifer on Cape Cod, MA, using a series of single-well injection tests. The aquifer contained a wastewater-derived contaminant plume, the core of which was anoxic and contained ammonium. The study was conducted near the downgradient end of the ammonium zone, which was characterized by inversely trending vertical gradients of ...


  • Validation of a New Method for Screening Soil and Water for TCE Contamination

    INTRODUCTION ASTM Method D 7203-06, Standard Test Method for Screening Trichloroethylene (TCE)-Contaminated Media Using a Heated Diode Sensor, (ASTM 2006) can be used to screen a sample of soil or water known to contain the halogenated volatile organic compound (HVOC) TCE. The method calls for measuring the TCE concentration in the headspace above the sample using a heated diode sensor ...

  • LIMS and the Automation of the Water Lab

    (Reproduced by permission from Laboratorium Magazine) Europe’s most modern water lab is located in Leeuwarden, in the Netherlands. Vitens made a big splash when it brought this modern building, with its transparent design, into operation in January 2005. Many colleagues from Dutch and foreign labs are eager to visit this installation, where water control samples are routed automatically with the ...
