  • Pathogenic features of heterotrophic plate count bacteria from drinking-water boreholes

    Evidence suggests that heterotrophic plate count (HPC) bacteria may be hazardous to humans with weakened health. We investigated the pathogenic potential of HPC bacteria from untreated borehole water, consumed by humans, for: their haemolytic properties, the production of extracellular enzymes such as DNase, proteinase, lipase, lecithinase, hyaluronidase and chondroitinase, the effect ...

  • Stratigraphy of Quaternary inner-shelf sediments in Tai O Bay, Hong Kong, based on ground-truthed seismic profiles

    High-resolution boomer profiles from Tai O Bay, Hong Kong SAR, were ground-truthed using ten discontinuously sampled boreholes penetrating bedrock with a maximum length of 82.1 m. The relationship between depth below seabed and seismic profiles was established through the measurement of two borehole compressional-wave velocity profiles. In departure from previous interpretations, nine Quaternary ...

  • IEG multi level sampling well (MLSW) case study - IEG Technologie GmbH

    The MLSW-system is used for the recovery of multiple high-quality samples of soil-gas and groundwater from numerous isolated horizons in a single standard borehole. The system is also used to accurately delineate contamination profiles in three dimensions, which is vital or the design, installation and monitoring of remediation systems. MLSWs also can be used for activly dispersing substances ...

  • An environmentally–friendly integrated seismic imaging for coal exploration in the Miocene Soma Basin, Western Turkey

    Seismic reflection data from target depths of several hundred metres have been acquired and processed as an aid for lignite exploration in the Miocene Soma Basin, western Turkey. An environmentally–friendly approach was followed by acquiring the data with mini–vibroseisseismic source along crooked lines, using available mountain/forest and village roads; quality control tests were conducted to ...

  • Potential soil characteristics for riverbank filtration using 2-D ground resistivity in Kota Lama Kiri, Kuala Kangsar

    Identifying the subsurface profile for riverbank/bed filtration (RBF) using conventional methods such as drilled boreholes is usually labor intensive, costly and acquires only 1-D profiling. Hence, a 2-D ground resistivity method was used as an alternative to obtain a 2-D subsurface profile by extending to 200 m length at Kota Lama Kiri, Kuala Kangsar, Perak site area. Four resistivity survey ...

  • H-ADCP Flow Gauge Installation

    Wessex Water contracted HL to install a new flow-gauge to provide flow data on the environmental impact of abstraction upstream and downstream of a riverside borehole for public-supply. Due to the channel and hydraulic conditions at the site on the River Yeo in Somerset, HL selected a horizontal ADCP Channelmaster device from Teledyne RDi for providing accurate velocity profiles at one elevation ...

  • Soil and groundwater assessment, North-West England

    Project Remediation Strategies were retained to undertake contamination delineation and assessment work at a logistics depot following an accidental release of a large volume of diesel.  An overnight failure in a joint on a pressurised fuel pipeline had resulted in a loss of 15,000 litres of red diesel. Initial response works identified a small proportion of the diesel had ...

  • High-Resolution Site Characterization with Multilevel Systems

    Within the last few years, the U.S. EPA added a new focus area on high-resolution site characterization (HRSC) to their Contaminated Site Clean-Up Information (CLU-IN) website. The U.S. EPA’s definition of HRSC is: “High-resolution site characterization (HRSC) strategies and techniques use scale-appropriate ...

  • ITRC technical regulatory guidelines for passive diffusion sampling, 2004

    Polyethylene diffusion bag (PDB) samplers are low-density polyethylene bags containing deionized water, used to collect water samples in groundwater wells for laboratory analyses of volatile organic compounds (VOCs). PDB samplers are passive devices, relying on the movement of groundwater from the aquifer or water-bearing zone through the screen or open interval of a well. VOCs in groundwater ...

  • Salinity modeling for the Altona sewerage strategy

    City West Water’s Altona sewerage system is possibly one of the most studied sewerage networks in Melbourne, Australia. Currently the tertiary sewage effluent from the Altona treatment plant is discharged to Port Philip Bay with an average salinity of approximately 4500 mg/litre.  This study involved the development of a detailed model that accurately reflected the sources and dilution of ...

  • Eco-Hydrology

    The Habitats Directive and the Environment Agency’s Restoring Sustainable Abstraction programme (RSAp) have focused attention on a large number of wetland sites across the country. Some of these are large, high profile sites that have been subject to many detailed studies in the past. However, many sites have had little work carried out on them and the behaviour of their hydrological ...

  • Sinking Costs

    Today there is more pressure than ever for businesses to minimize costs and increase productivity. Companies are always looking for ways to reduce overall costs. Unfortunately, these efforts are often hampered when a company is faced with an environmental investigation. Regulatory agency requirements, such as determining the full horizontal and vertical extent of contamination in soil and/or ...
