  • A Self-Boring Pressuremeter System

    The paper describes some of the development work on the Cambridge University version of the self-boring pressuremeter (the so-called “Camkometer”), which has been carried out at the University of Western Australia over a number of years. This work included improvement of the pore-pressure measuring system and development of a deairing system for the pore-pressure transducers, new supply-voltage ...

  • New advances in planning a bore

    Software helps take out the guesswork Horizontal directional drilling (HDD) is challenging and difficult work fraught with unknown obstacles. While it’s not possible to eliminate every obstacle, bore planning software tools developed by drill manufacturers can help small and large contractors create a bore plan that may help minimize risks. Bore planning software was ...

  • Uncertainty Analysis of Mound Monitoring for Recharged Water from Surface Spreading Basins

    This study has conceptually reviewed issues related to implementation of a groundwater mound monitoring well (GMMW) for monitoring recharged water from a surface spreading basin with emphasis on uncertain hydrogeological conditions. For this, we selected a recharge site in the City of Mesa, Arizona, that is characterized with near surface clay lenses of low permeability. A geostatistical ...

  • Precise Contaminant Distribution Delineation Using Membrane Interface Probe (MIP) Technology (PDF)

    Project site: a former Air Force Base, Portsmouth, NH Project objectives: to obtain a comprehensive set of data regarding the distribution of the jet fuel in the subsurface prior to the injection of Oxygen Release Compound (ORC), a bioenhancing product. The subsurface data were used to achieve precise placement of the ORC. Technology utilized: Membrane ...

  • Chlorofluorocarbon (CFC) remediation case study 2002

    Project Description The project site is located in Northern California and was leased and operated as a chemical storage and solvent recovery operation from late 1972 through April 1993. During an earlier period, the site may also have been used as a waste transfer station. Previous investigations indicate that soil and groundwater at the site, and groundwater down-gradient (westward) from ...

  • Assessment, Field Testing, and Conceptual Design for Managing Dense Non-Aqueous Phase Liquids (DNAPLs) at a Superfund Site

    AbstractDense non-aqueous phase liquids (DNAPL) greatly complicate groundwater remediation because the heavy DNAPL will sink and follow topographic lows within an aquifer system, and because DNAPL is difficult to extract using conventional pumping methods. These problems are now ...


  • Chloroflourocarbon (CFC) remediation case study

    Project Description The Site location was an industrial facility located in the greater South Los Angeles region that manufactured chemicals for local petrochemical and other industrial operations from 1919 through late 1990’s. Refrigerants were initially produced in 1964 including chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) such as trichlorofluoromethane (R-11), ...

  • Establishing environmental baseline case study

    Challenge: A major integrated oil company, intending to divest a portfolio of 68 retail petroleum facilities in the northwest United States, requested the services of Antea Group to conduct Phase II Environmental Site Assessments in order to establish an environmental baseline prior to selling the assets. Among the project-specific challenges were a short performance timeframe, a newly ...

  • Achieving

    Introduction The leak repair requirements, under Title VI Section 608 of the Clean Air Act Amendments of 1990, require that when an owner or operator of an appliance that normally contains a refrigerant charge of more than 50 pounds discovers that refrigerant is leaking at a rate that would exceed the applicable trigger rate during a 12-month period, the owner or operator must take corrective ...


  • Do You Know the 4 V’s of Big Data?

    From professional sports, to advertising, to investment banking and almost everything in between. Big data is driving thousands of decisions each day that impact us all in areas big and small. But what is big data exactly, and how or why should it impact efforts in the realm of health and safety? First a definition of big data itself. Big data is a term that began to emerge over the last decade ...

  • New monitoring technology helps reveal Arctic secrets

    A group of Arctic researchers has employed the latest monitoring technology to investigate the effects of climate change, by measuring temperature and salinity in the water column beneath surface ice. The results of the investigation, which utilised YSI’s new 'Castaway-CTD', could cast new light on our understanding of the ways in which shifting ocean currents impact upon the climate in ...

  • What’s the Temperature? Thermal Modeling and its Importance in Thermal Remediation

    What is a model? A beautiful person who struts down a run way, a scaled down sculpture of the Empire State Building, or a series of equations that describe some phenomenon? Did you guess all of the above? Gold star! Models come in many different shapes and sizes. In the environmental consulting and remediation industry, the word “model” often refers to a numerical model. Numerical ...
