  • Geostatistical Sampling Optimization and Waste Characterization of Contaminated Premises

    Abstract This methodological study presents a geostatistical approach suitable for radiological evaluation in nuclear premises. By modelling the spatial continuity of activities, geostatistics provide sound methods to estimate and map radiological activities, together with their uncertainty. The main geostatistical principles are first recalled and illustrated on a real premise ...

  • Increased sample throughput for ICP-OES on drinking water and waste water

    The application of an SC-FAST sample introduction system to the analysis of natural and certified water samples is described. The SC-FAST system consists of an autosampler, sample loop, switching valve, high efficiency nebulizer and a glass cyclonic spray chamber to perform analysis by direct nebulization. The potential benefits of this introduction system are numerous and include: increased ...

  • Biodegradation Tests for Wastewater Samples

    Biodegradation Tests for Wastewater Samples Biodegradation tests usually involve comparison of the oxygen uptake of a test sample – or gas production for anoxic or anaerobic tests – to that for a readily biodegradable control substrate (usually acetic acid, ethanol, or aniline). While biodegradation characteristics can vary among chemical types and wastewater sources, typical patterns are shown ...

  • General Air Sampling Guidelines (PDF)

    This Standard Operating Procedure (SOP) provides guidance in developing and implementing sampling plans to assess the impact of hazardous waste sites on ambient air. It presents the United States Environmental Protection Agency/Environmental Response Team's (U.S. EPA/ERT's) approach to air sampling and monitoring and identifies equipment requirements. It is not within the scope of this SOP to ...

  • Setting the standards for headspace sampling by PID

    The responsiveness of PIDs to virtually all VOCs has seen them become the accepted tool for initial site entry assessment, ensuring optimal detection of unknown and often toxic or hazardous chemicals found at hazardous waste sites and chemical emergencies. The speed and accuracy of modern PID equipment means that many worker and community safety concerns during initial and ongoing operations can ...

  • Determination of Polychlorinated Biphenyls (PCB) and Phthalates in Waste Polymer Samples intended for Mechanical Recycling

    The purpose of this study was to determine the levels of polychlorinated biphenyls (PCBs) and phthalates in homogenized polymer samples from polymer waste streams using two different pressurized fluid extraction instruments (ASE and SpeedExtractor). Both extraction methods showed very similar results. Measured PCB levels were in the lower and sub ppm range. Calculated total PCB levels using the ...

  • Use of stratified cluster sampling for efficient estimation of solid waste generation at household level

    Relatively few studies have been performed to characterize municipal solid waste (MSW) at household level. This is due in part to the difficulties involved with collecting the data and selecting an appropriate statistical sample size. The previous studies identified in this paper have used statistical tools appropriate for analysing data collected at a material recovery facility or landfill site. ...

  • Determination of Total Petroleum Hydrocarbons in Soil, Sediment, and Waste Samples using the SpeedExtractor E-916

    Total petroleum hydrocarbons (TPH) are a family of several hundred chemical compounds made from crude oil. TPH are found in soils and water. Exposure to TPH can affect human health and, therefore many laboratories around the world are analyzing TPH levels in the environment. This application note describes the extraction of TPH from soil, sediment, and waste samples using the SpeedExtractor ...

  • TOC Determination in Solid Samples using the Suspension Method

    The TOC content in solids plays an important role in the classification of soils, sludges and sediments. According to the German Ordinance on Environmentally Compatible Storage of Waste from Human Settlements, TOC in solid materials is one of the key parameters for the characterization of wastes as part of the acceptance control of landfills. This important control measure requires a ...

  • Biosolids sampling and handling approaches for microbial analyses

     ABSTRACT The protection of human health and the environment while making the use of biosolids products more practical is a joint goal of utilities and regulatory agencies. Assuring the safety of biosolids is paramount to gaining wide public acceptance of this waste-to-beneficial use product. Making effective decisions about the safety of biosolids use relies on quality data. Satisfying ...

  • Residential Vapor Intrusion Evaluation: Long Duration Passive Sampling v. Short Duration Active Sampling

    Abstract Sampling indoor air for potential vapor intrusion impacts using current standard 24-hour sample collection methods may not adequately account for temporal variability and detect contamination best represented by long-term sampling periods. Mr. Henry Schuver of the U.S. Environmental Protection Agency (EPA) Office of Solid Waste staled at the September 2007 Air & Waste Management ...

  • Flaxseed Oil Waste

    A commercial manufacturer of flaxseed oil was having a problem obtaining the FOG and TSS level required by their local POTW. A sample was submitted to our laboratories for treatment analysis. The wastewater was at a pH of 7.0 so no adjustment was required. The sample was treated with Floccin J and the results met their ...

  • Efficient Waste Water Treatment

    Clean drinking water is an essential need of mankind. Often surface water like rivers or lakes is used as drinking water source. To prevent these resources from pollution the effective treatment of waste water is a must. For example in China 75% of discharged waste water is coming from pulp and paper, textile and dyeing industries. To run a waste water treatment plant in the most efficient way ...

  • Tackling waste in the sands of the Sahara

    When gas was discovered in the mid Sahara areas of North Africa in the 1990s Andy Ive was asked by BP to help set up the water and waste infrastructure for what amounted to four small towns 600 km into the desert. No local infrastructure at all existed for the waste and water to be produced by 2-3000 workers. IVE overcame sandstorms, extreme heat, poisonous snakes and patented a novel solution to ...
