  • Case study - Oil analysis - House Calls - Help reduce offshore equipment failures

    A new approach It is hard to think of another environment where an equipment failure could have a greater negative impact on employee safety and lost production than an offshore oil and gas production platform. Yet offshore platforms are among the world’s most difficult locations to operate and maintain equipment. In most cases, skilled people and supplies can only reach the ...

  • A practical low-cost model for prediction of the groundwater quality using artificial neural networks

    The quality monitoring of water wells is always a costly and time-consuming process. To avoid the unnecessary cost and time of future sampling, applying some powerful and well known prediction models can be a suitable alternative. In this research, the groundwater quality of Amol-Babol aquifer was predicted using the artificial neural network (ANN) model with a data set from 1987 to 2010. ...

  • 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 ...

  • Oil Sampling Best Practices

    Obtaining a representative oil sample from a closed loop lubrication system is essential to any good oil analysis program. As oil analysis programs become more standardized for routine monitoring, especially within equipment warranty support programs, equipment makers provide more sampling points on new equipment. These ...

  • Oxidative treatment of diclofenac via ferrate(VI) in aqueous media: effect of surfactant additives

    The potential reaction of diclofenac (DCF) with ferrate(VI) and influences of coexisting surfactants have not been investigated in depth, and are the focus of this study. The results demonstrated that DCF reacted effectively and rapidly with Fe(VI) and approximately 75% of DCF (0.03 mM) was removed by excess Fe(VI) (0.45 mM) within 10 min. All of the reactions followed pseudo first-order ...

  • GoForth, NC Case Study

    ABSTRACT Trap & Treat® BOS 200® was used to remediate petroleum hydrocarbon impacted groundwater within fractured bedrock and overburden soil at a former retail gasoline site in North Carolina. After a thorough remedial design characterization was completed, BOS 200® was surgically injected over two field events to successfully achieve the ...

  • How HDXRF Helps Volcom Comply with Global Regulations - Case Study

    Volcom, Inc. is a lifestyle brand that designs, markets, and distributes high-quality boardsportsoriented products like clothing, footwear and accessories. As a global company, their restricted chemicals list is a combination and reflection of many international standards. CPSC and Proposition 65 lead the way for many of the chemicals’ lower limit regulations, but Canadian, Chinese, and ...

  • Source tracking of Enterococcus moraviensis and E. haemoperoxidus

    Enterococci were detected occasionally in 100 L samples of water abstracted from a shallow aquifer in a natural dune infiltration area for drinking water production. Enterococcus moraviensis was the species most frequently identified in these samples. Because there are no existing reports of faecal sources of E. moraviensis and the closely related E. ...

  • On the right track

    High-speed train manufacturer, CAF, rely on world-class beamforming technology to reduce the noise generated by their trains – helping to make high-speed trains a more viable option for travellers and operators alike. Because of its relatively low levels of CO2 emissions, train travel is considered one of the ...

  • Radon-222 from different sources of water and the assessment of health hazard

    Water samples collected from different sources were analysed for radon concentrations in order to evaluate the health effect associated with radon in water. The radon concentrations were in the range of 3.56–98.57, 0.88–25.49, 0.73–1.35 and 0.24–1.03 Bq.L−1 for borehole, well, packaged and utility water, respectively. Samples from boreholes had the highest radon concentrations with about 67% ...

  • Norovirus genogroups I and II in environmental water samples from Belém city, Northern Brazil

    This study investigated the presence of norovirus (NoV) GI and GII in environmental samples from the northern region of Brazil. Water samples were collected monthly (November 2008/October 2010) from different sources and sewage and concentrated by the adsorption-elution method. The NoV investigation used molecular methods followed by sequencing reactions. The general positivity for NoV was ...

  • Do storm event samples bias the comparison between sewer deposits contribution?

    Previous researches demonstrated the occurrence of unique in-sewer sediment, the organic layer, on the Marais site in Paris, capable of explaining the entire wet weather sewer production of suspended particles. Other studies on sites having no similar organic sediment, Clichy in Paris and Ecully in Lyon, demonstrated a wet weather sewer deposits contribution (SDC) to effluent pollution ...

  • Microbial source tracking of private well water samples across at-risk regions in southern Ontario and analysis of traditional fecal indicator bacteria assays including culture and qPCR

    Many people living in rural areas rely on privately owned wells as their primary source of drinking water. These water sources are at risk for fecal contamination of human, wildlife, and livestock origin. While traditional bacteriological testing involves culture-based methods, microbial source tracking (MST) assays present an opportunity to additionally determine the source of fecal ...

  • Beliefs, Politics, and Environmental Policy

    Introduction Many of us who work on environmental issues have faced the challenge of conveying their importance to nonspecialists. Perhaps we have found ourselves defending the robustness of climate science to a contrarian uncle, or extolling the importance of biodiversity to a dubious aunt. Our relations and friends are often educated people, skilled in their own professions, who have ...

  • Using nanometer TiO2 modified with cetyl trimethyl ammonium bromide for separation and preconcentration of Parathion in water sample

    In this work, nanometer TiO2 modified by cetyl trimethyl ammonium bromide (CTAB) was used as adsorbent for solid-phase extraction (SPE) of Parathion in environmental water samples. Adsorbed Parathion was then desorbed with different eluents and determined by gas chromatography (GC)/flame ionization detection. Greater selectivity, resolution, and sensitivity have been seen by GC compared with ...
