  • 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 ...

  • Groundwater Plume, Source and Risk Identification Using Passive Soil Gas

    Abstract The results from sixty passive soil gas (PSG) samplers placed at a grain silo and mixed-use industrial facility with a known chlorinated solvent release aided with the rapid investigation time-schedule. The samplers were used to determine potential sources, plume extent and vapor risks in areas beyond the previous discrete soil sampling and permanent groundwater monitoring well ...

  • 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 ...

  • The 75-year history of soil sampling equipment supplier, AMS

    Almost 75 years ago in the small town of American Falls, Idaho, a man had a dream and a vision. Art Vollweiler had the philosophy that “everything was a work of Art.” Associating his name with everything he created meant something in 1942. It meant that everything he designed and built was made to last. Art’s assurance in quality has stood the test of time, and continues to be ...

  • DOC and UVA attenuation with soil aquifer treatment in the saturated zone of an artificial coastal sandfill

    Results from a direct recharge experiment conducted in the field to investigate DOC and UVA254 attenuation rates during the direct injection of UF treated wastewater into a artificial coastal sandfill are presented in this paper. Approximately 500 m3 of ultra-filtered wastewater was injected into the saturated zone, over a period of 9 days. The movement of the plume was tracked over 80 days, ...

  • Manufactured gas plant investigation

    A two-person BEACON field team installed 304 PSG Samplers over a two-day period. Samplers were installed through soils, gravel, asphalt, and concrete. To accommodate field schedules, the Samplers were exposed for eight days in the field and the two-person field team required one day for retrieval of the Samplers. Survey results clearly showed where source areas are present on the site, as well as ...

  • Small Diameter Piston Sampling with Cone Penetrometer Equipment

    A small diameter piston sampler that can be operated by a cone penetrometer rig has been developed specifically for recovery of sand and clay samples under conditions where sample recovery using ordinary means is difficult. The 22-mm-diameter sample that is recovered in a polythene sheath is valuable for visual examination of the soil rather than for most laboratory testing purposes. Provided the ...

  • Tracking chiral polychlorinated biphenyl sources near a hazardous waste incinerator: Fresh emissions or weathered revolatilization?

    The Swan Hills Treatment Centre (SHTC), located in central Alberta, is the primary facility in Canada for incinerating polychlorinated biphenyls (PCBs). Past studies have shown significant contamination by PCBs and other pollutants of the immediate surrounding region. However, it is unclear whether the major source of contamination to the region's atmosphere is historical release incidents or ...

  • The radiological impact on some workers due to the natural radionuclides from some industries

    A total of 37 different soil samples and 22 air samples were collected from natural industrial sources. The air samples were collected at a height of 1 m above the ground on 10.4 cm diameter filter paper (with a desired collection efficiency) using a high-volume air sampler. The activity concentration levels of naturally occurring radionuclides such as the U-238 series and Th-232 series were ...

  • Asarco Plant site remediation case study

    Asarco, Inc. Omaha, Nebraska, USA For more than a century, the former American Smelting and Refining Company (Asarco) operated a lead refinery on the banks of the Missouri River in Omaha, Nebraska. Plant closure in 1997 presented an opportunity to reclaim the riverfront as public space. Led by HDR, this successful transformation became the largest voluntary clean up ...

  • DNAPL Characterization Methods and Approaches, Part 2: Cost Comparisons`, Ground Water Monitoring & Remediation

    Contamination from the use of chlorinated solvents, often classified as dense nonaqueous phase liquids (DNAPLs) when in an undissolved state, pose environmental threats to ground water resources worldwide. DNAPL site characterization method performance comparisons are presented in a companion paper (Kram et al. 2001). This study compares the costs for implementing various characterization ...

  • Short-term variations in ambient particulates and their sources in Taichung, Taiwan

    Ambient particulate measurements were carried out using TE-PUF sampling and a Universal Air Sampler between 8 March and 25 April 2001 at Taichung. Samples were collected every 6 hours beginning at 0100 LST (Local Standard Time) each day at two sites, one at a university campus and the other at a roadside. Chemical species (Cl-, NO3-, ...

  • Standard Chlorine of Delaware Remediation

    By designing a 70-foot deep barrier wall, Black & Veatch was able to cut off contaminant source areas from a creek near New Castle, Delaware. The groundwater treatment system that Black & Veatch designed prevents site contamination from reaching the underlying drinking water aquifer. The Standard Chlorine of Delaware Site is a 65 acre area including an abandoned chlorobenzene ...

  • Review of polyoxymethylene (POM) passive sampling methods for quantifying freely‐dissolved pore water concentrations of hydrophobic organic contaminants

    Methods involving polyoxymethylene (POM) as a passive sampler are increasing in popularity to assess contaminant freely‐dissolved porewater concentrations in soils and sediments. These methods require contaminant‐specific POM‐water partition coefficients, KPOM. Specific methods for determining KPOM perform reproducibly (within 0.2 log units). However, different methods can lead to highly ...

  • Source contribution of atmospheric aerosols in Bangkok metropolitan area by CMB8 receptor model

    The CMB8 model was applied for source apportionment of particulate matter in Bangkok area. The 24 h of ambient data were collected and analysed for elemental composition during December 1996 to January 1997 by high volume air samplers at a station in Bangkok, Thailand. Seven source profiles and the average mass concentrations of 42 ambient data were used to run the chemical mass balance ...
