  • Using a Ground Penetrating Radar (Important terms)

    Air Low dielectric (~1), high velocity material i.e. EM waves travel almost at the speed of light. In air the emission pattern of GPR antennas is broader than in the ground. It is recommended to place the GPR as close to the ground as possible to direct emission energy further into a material. Some applications of GPR include emission exclusively in air.Ground / ...

  • AMS History

    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 ...

  • Performing Bridge Deck Inspections with Ground Penetrating Radar

    Maintenance of the nation’s infrastructure is a growing concern. No one wants to be delayed by road closures due to emergency repair. Unfortunately, often the organizations responsible for repairing and maintaining our roads are unaware of areas in the roads that need repair until the road is so damaged that it requires emergency repair. In the case of sensitive road areas like ...

  • Meltwater flow through a rapidly deglaciating glacier and foreland catchment system: Virkisjökull, SE Iceland

    Virkisjökull is a rapidly retreating glacier in south-east Iceland. A proglacial lake has formed in the last ten years underlain by buried ice. In this study we estimate water velocities through the glacier, proglacial foreland and proglacial river using tracer tests and continuous meltwater flow measurements. Tracer testing from a glacial moulin to the glacier outlet in September 2013 ...

  • U.S. troops get boost from soil sampling equipment supplier

    Top of the line soil sampling equipment isn’t the only thing that AMS produces. They also produce smiles on the faces of United States Troops overseas. The holidays can be lonely for U.S. troops, but it can also be immensely joyful when they know they have love and support from back home; not just from friends and family, but from complete strangers.  Rick Vollweiler, ...

  • Large TCE Plume with Extensive DNAPL - Case Study

    ABSTRACT High density sampling program was key to remediation of soil and groundwater impacted by TCE DNAPL at a former industrial site underlain by river deposits and sedimentary bedrock. CHALLENGES Impacted alluvium consisted of poorly sorted, fine to coarse grained sand. The source area was underlain by an aquitard of silt and clayey silt where dense ...

  • Automated screening of explosives in soil samples by online SFE-SFC-MS

    There are a large number of explosives-contaminated sites in the US, Europe, and Asia. High levels of explosives in soil can threaten the health of humans, livestock, and wildlife. A number of remediation efforts are underway, which require the analysis of explosives in soil samples. Recently, a new technique was introduced that allows the automated supercritical fluid extraction and SFC ...

  • Case study - UVF and LIF used together at oil refinery site

    A former oil refinery in Kansas has a 100-acre size plume of oil. The NAPL is commingled with gasoline, diesel, crude oil and other petroleum products. An environmental consultant used Sitelab’s UVF to field screen hundreds of soil samples for EPH C11-C22 aromatic hydrocarbons. Split samples sent to a confirmatory lab directly correlated (see graph). Laser Induced Fluorescence (LIF) had ...

  • Case study - Nigeria crude oil in soil site

    Safic Technologies, Ltd. - Port Harcourt A pilot study was conducted testing soil samples collected from a pipeline spill. Split samples were sent to Sitelab for EDRO analysis and results were the same. Samples were also sent to a Nigerian lab and a highly reputable lab in the United States for confirmation. After testing the samples a second time, the American lab got better results. ...

  • Source Area Remediation of PCE in Soil - Fair Lawn, New Jersey - Case Study

    TRS Group, Inc. (TRS) was retained by Anderson Mulholland and Associates, Inc. (AMAI) to perform an Electrical Resistance Heating (ERH) remediation of DNAPL in soil at the former Topps Dry Cleaners property in Fair Lawn, NJ. The remedial goal of this project was a reduction of tetrachloroethene (PCE) in soil to less than 1 milligram per kilogram (mg/kg) in every soil sample. Final confirmatory ...

  • Using sediment cores to establish targets for the remediation of aquatic environments

    When assigning site-specific restoration targets for deteriorating aquatic systems, it is necessary to have an understanding of the undisturbed or background state of the system. However, the site-specific characteristics of aquatic systems prior to disturbance are mostly unknown, due to the lack of historical water and sediment quality data. This study aims to introduce a method for filling ...

  • Historical decline and altered congener patterns of polychlorinated dibenzo‐p‐dioxins and dibenzofurans in fish and sediment in response to process changes at a pulp mill discharging into Jackfish Bay, Lake Superior

    Improved regulations for pulp and paper mill effluents and an industry shift away from elemental chlorine bleaching in the 1990s greatly reduced the release of polychlorinated dibenzo‐p‐dioxins and dibenzofurans (PCDD/Fs) into the environment. However, the high potential of these contaminants to persist in sediment and bioaccumulate in biota means that they have remained a concern. To document ...

  • Internal phosphorus load in a mexican reservoir: Forecast and validation

    To determine the internal phosphorus load (IPL) as a function of redox potential (Eh) in a Mexican reservoir, we extrapolate the results from a phosphorus (P) release experiment to temporal and spatial variations of Eh in sediments, obtaining an IPL‐Eh of 24.2 ± 2.5 t/yr. This result is compared to the P mass balance (MB) in the reservoir, where the IPL‐MB is determined as the difference ...

  • Optimizing the production of Polyphosphate from Acinetobacter towneri

    Inorganic polyphosphates (PolyP) are linear polymers of few to several hundred orthophosphate residues, linked by energy-rich phosphoanhydride bonds. Four isolates had been screened from soil sample. By MALDI-TOF analysis, they were identified as Bacillius cereus, Acinetobacter towneri, B. megaterium and B. cereus. The production of PolyP in four isolates was studied in phosphate uptake medium ...

  • Archaeological survey 2

    The site of the Meadows’ Wesleyan Cemetery in the Adelaide is thought to contain more than 130 unmarked graves. This site initially had a chapel constructed on it in 1840 and the first burial in 1855.  The initial chapel was replaced by a more substantial stone building in 1856.  Burials continued in this cemetery sporadically until the 1940’s although the site became less ...
