  • The Basics of Slope Stability Analysis for Geosynthetics

    Slope stability analysis is vital to preventing slope failures in a variety of engineering applications including landfill design, roads, dams and embankments, to name a few. Proper analysis anticipates both natural and manmade slopes and failure of foundations and retaining walls. This blog covers the necessity of slope stability analysis, how to conduct the analysis and the role of ...

  • Modeling Tip: How to Import BREEZE AERMOD files into BREEZE Risk Analyst for Human Health Risk Assessments

    Humans can be exposed to hazardous air pollutants (HAPs) either directly through inhalation or indirectly through ingestion or dermal contact, which can result in acute or chronic health effects. The risk of exposure varies depending on a number of variables, including the meteorological conditions, local geographical and emissions characteristics, the age of the individuals being exposed, and ...

  • Purge Trap for GC Analyses of Volatile Aromatic (BTEX) Compounds in Soils and Sediments

    The BTEXTRAP purge trap was designed specifically for monitoring benzene, toluene, ethylbenzene, and the xylene isomers (BTEX compounds).  The trap allows large amounts of methanol (used in the US EPA Method 5030 procedure for preparing soil and sediment samples) to pass through the adsorbent beds while retaining the analytes of interest.  In evaluations of trap performance, relative ...

  • Comparison of linear and non–linear, space frame–raft–soil interaction analyses, by using finite element method

    The objective of the present study is to estimate the realistic displacements and force quantities in the structural members, accounting for their three dimensional behaviour and non–linear constitutive relations of soil. This demands usage of proper constitutive model for soil and its numerical model, which is validated experimentally. A program has been developed in the present work to compare ...

    Leading instrumentation company HACH LANGE is helping a number of key customers save valuable time and costs with its new IL550 TOC-TN analyser. TOC analysis is vitally important in applications ranging from power generation, wastewater, drinking water, surface water and ultrapure water, to agricultural soils, contaminated land and food. HACH LANGE analysers therefore offer a range of options ...


  • Hired metals analyser ensures remediation success

    Cognition Land and Water Ltd, a UK based remediation specialist, has hired a portable XRF metals analyser to improve the speed of remediation work at a project in London’s Kentish Town. The project had a major impact on local residents so timescales were extremely tight but Cognition’s Charlie Jarvis says “It would not have been possible to meet the deadline without the use of ...

  • Soil geography and geostatistics

    Geostatistics, which can be defined as the tools for studying and predicting the spatial structure of georeferenced variables, have been mainly used in soil science during the past two decades. Since now, hundreds of geostatistical papers have been published on soil science issues. The use of geostatistical tools in soil science is diverse and extensive. It can be for studying and predicting soil ...

  • Assessment and Reporting on Soil Erosion

    Untitled Document This report presents the results of a peer review of work on soil erosion carried out by the EEA up until 2001. It also summarises the conclusions of an expert ...

  • Analysing the sensitivity behaviour of two hydrology models

    Recently, the New Morris Method has been presented as an effective sensitivity analysis tool for mathematical models. The New Morris Method estimates the sensitivity of an output parameter to a given set of input parameters (first-order effects) and the extent these parameters interact with each other (second-order effects). This method requires the specification of two parameters (runs and ...

  • The role of soil chemistry in wine grape quality and sustainable soil management in vineyards

    ABSTRACTThis study aimed to establish if there is any evidence that soil mineralogical and/or chemical composition influence the composition and quality of wine grapes. In the initial phase of the study, soils and grapes were sampled in two riesling vineyards in South Australia. Soils were analysed for a wide range of total major and trace elements; soil cation extracts and grape juices were ...

  • Transcriptional profiling of the soil invertebrate (Folsomia candida) in pentachlorophenol contaminated soil

    Pentachlorophenol (PCP) as a widely used pesticide is also considered to be an endocrine disruptor. Molecular effects of chemicals with endocrine disrupting potential on soil invertebrates are largely unknown. In this study we explored the transcriptional expression changes of collembola (Folsomia candida) in response to PCP contamination. A total of 92 genes were significantly differentially ...

  • Holistic approach to biodiversity and bioindication in soil

    After the Rio Conference in 1992, Biodiversity became synonymous with protecting the environment.Bioindication has emerged as useful process for environmental evaluation particularly of the soil, whichis a complex entity able to perform a multitude of key functions, vital for life, such as breathing,assimilating nutrients like carbon and nitrogen, transforming and mineralizing organic materials ...

  • An investigation and remediation of TNT contaminated soils.

    An investigation and remediation of TNT contaminated soils and wastes was conducted at the Apache Powder Superfund Site in Cochise County, Arizona during 1999 and 2000. TNT contamination was most likely the result of salvage operations of World War I munitions. Characterized by a steep hillside and arroyo cutting through the wastes, the site offered challenges of stability, access, health and ...

  • Spoil, rubble and a soil-tar mix

    National Grid and Wales and West Utilities recently completed their first joint remediation project at the Aberaman Gasworks following the sale of the Wales and south west of England gas network in 2005. Here Scott Lewis from National Grid and Ashley Griffiths from Wales and West Utilities explain the challenges and processes. The project was undertaken using a stabilisation and solidification ...

  • Cleanup criteria for radionuclides in US surface soil

    The maximum concentrations of individual contaminants that will be allowed to remain in the environment after cleanup are developed on a case-by-case basis and may depend on site-specific risk analyses as well as stakeholder concerns. A database of cleanup criteria has been established from site-specific agreements at US Department of Energy (DOE) remediation sites and was used to analyse the ...

  • Soil and groundwater assessment, south-east England

    Project Remediation Strategies were appointed to undertake a soil and groundwater assessment to assist a client in understanding the potential environmental liabilities associated with the shallow soils beneath part of the site.  The client was undertaking a phased renewal of the site tank farm areas, which required the excavation and replacement of shallow soils to allow for new ...

  • Bioremediation of ground water by treatment of soil at source with Vaporremed

    A heating oil company during servicing of a home in PA released almost 150 gallons of heating oil that seeped into the basement and below. Ground water was shallow and PA DEP wanted to ensure that the contamination did not pollute the water. The environment company overlooking the cleanup decided to use VaporRemed to reduce the fumes. In three weeks time the level of contamination of the soil and ...

  • Tungsten effects on microbial community structure and activity in a soil

    Tungsten, once deposited onto a soil as a result of private, industrial, and military activities, may persist as tungstate anion or, via polymerization, as a variety of poly-tungstate species, each with varying solubility and soil sorption characteristics. In this study, the impact of weathered tungsten on a soil microbial community was measured. Fatty acid analyses indicated that weathered ...

  • Prediction of Soil and Nutrient Losses in A Highland Catchment

    Highland catchments in tropical regions are frequently subjected to soil erosion and the transport of chemicals downstream. Any drastic changes in land use will increase the severity of these processes of land degradation. A simulation study using GLEAMS (Groundwater Loading Effects of Agricultural Management Systems) was conducted at a catchment presently under tea farming in Cameron Highlands, ...
