  • Articulated Concrete Blocks Provide Much Needed Protection for Your Pipeline

    One of the many ways that articulated concrete blocks can protect pipelines is by adding structural stability in areas that are particularly prone to erosion. This erosion is not the only type of hazard posed to your pipeline, though, and if you don’t have the proper protection in place, your pipeline could be susceptible to deterioration at the hands of these other threats as well: ...

  • London Hotspots for Noise Nuisance Complaints [Infographic]

    As we continues our quest to build up a noise nuisance map of the UK, we recently turned our attention to our fair Capital, London. With 33 boroughs in Greater London, it was always going to be something of a time-consuming task to get the noise complaints data via Freedom of Information (FOI) requests. However, we were pleasantly surprised by the London Local Authorities efficiencies. The vast ...

  • Fire Codes: A Foundation of Safety for a Rapidly Changing World

    Chief among these safety features is fire protection. There are myriad codes and regulations relating to fire safety in commercial buildings, from standards on portable fire extinguishers to the installation of stationary pumps for fire protection — the U.S.- based National Fire Protection Agency (NFPA) alone has more than 300 consensus codes that have been adopted in whole or in part ...

  • 99% of Interceptor contamination remediated - Case study

    What is an Interceptor Tank? An interceptor tank is a trap used to filter out hydrocarbon pollutants from rainwater runoff. It is typically used in road construction and on petrol station forecourts to prevent fuel contamination of the water table via runoff. Petrol interceptors work on the premise that some hydrocarbons such as petrol and diesel float on the ...

  • Nonaqueous Phase Liquids Compatibility with Materials Used in Well Construction, Sampling, and Remediation

    The EPA Regional Ground Water Forum is a group of EPA professionals representing Regional Superfund and Resource Conservation and Recovery Act Offices (RCRA), committed to the identification and resolution of ground-water issues impacting the remediation of Superfund and RCRA sites. The Forum is supported by and advises the Superfund Technical Support Project. The compatibility of remediation, ...

  • Escalating well construction costs in South Florida significantly exceed ENR construction cost index

    The South Florida Water Management District (SFWMD) develops long-term, comprehensive regional water supply plans to provide for current and future water use. The use of alternative water supplies is extremely important to the development of future water supply in South Florida. Alternative water supplies include brackish water sources that must be converted to potable water using desalination ...

  • Think health as well as safety

    Lee Calver of Workplace Law writes about how the HSE is making sure that the construction industry ‘thinks health’ as well as safety’. Not many weeks pass without the Health and Safety Executive (HSE) releasing new research or detailing ...

  • Oil and gas well’s fires

    In this paper we will introduce the oil well’s fires and model their modern extinguishing process. The fire mechanism was introduced and its quenching mathematical model was constructed based on the fire thermal parameters. The solution of this program was enhanced with the help of the international MATLAB program and its solution was based on the available international oil fire data. Then the ...


  • Evaluation of a Horizontal Well

    Background: Air Sparging Air sparging is an in-situ remediation technology where air is injected into the saturated zone of an aquifer. It is an alternative to conventional ex-situ pump and treat systems for remediation of contaminated ground water. It is necessary to understand the pattern of air flow that will occur in the subsurface in order to determine the optimal placement, ...

  • Abandoning Monitoring Wells: Safety Issues

    Monitoring wells are typically constructed to gauge the extent of contamination, assess water quality and conduct other hydrogeologic studies. Depending on its objective, the monitoring well may remain in use or may be abandoned permanently. When declared inactive, the well is many a times left as it is. Open unused wells are hazardous to life and environment: • Contamination may spread from one ...

  • In-well Vapor Stripping - Technology Overview

    In-well vapor stripping technology involves the creation of a ground-water circulation pattern and simultaneous aeration within the stripping well to volatilize VOCs from the circulating ground-water. Air-lift pumping is used to lift ground-water and strip it of contaminants. Contaminated vapors may be drawn off for aboveground treatment or released to the vadose zone for biodegradation. ...


  • Extraction well design for DNAPL recovery.

    The potential for downward migration of dense nonaqueous phase liquid (DNAPL) into deeper portions of a saturated hydrogeologic unit has important implications for successful groundwater remediation. Little information has been published regarding the design of extraction wells that allow DNAPL recovery without simultaneously creating a conduit for cross contamination by vertical migration ...

  • Latin America well-positioned for CDM

    The coastal desert of Colombia’s La Guajira state is a world away from Kyoto, the temperate Japanese city where representatives of 159 countries in 1997 signed the Kyoto Protocol on reducing greenhouses gases. The Caribbean laps against rickety settlements. Herds of goats range across scorching sands. Months, whole years, pass without rain. But Kyoto is well known to the inhabitants of La ...


  • Geotextiles in Construction Dewatering

    Woven geotextiles work wonders in dewatering applications as wraps around well screens and sump pit screens. The textile can be sewn into sleeves or tubes to be slid over the well screen or sump pit framework. This technique allows the user to compensate for well screens with slots that are too large or for sump pit piping with large perforations. By adding the geotextile sleeves the user ...

  • Temporary Construction Dewatering Solutions

    Mention “dewatering” to anyone outside of the underground construction trade, and typically, with a blank stare, they’ll ask what is D-watering? Mention dewatering to anyone in the underground construction trade, and they’ll likely state that it is one of the most important phases in the project, as a well designed and installed dewatering system will allow them to ...

  • Performance characterisation of a constructed Wetland

    Performance of a constructed wetland is commonly reported as being variable due to the site specific nature of influential factors. This paper discusses the outcomes from an in-depth study which characterised the treatment performance of a wetland based on the variation in the runoff regime. The study included a comprehensive field monitoring of a well-established constructed wetland in Gold ...

  • Geotech and construction case study

    Pre-Construction Surveys The VIY2-300 GPR was used to survey Korolenko Square and contiguous area in Rivne town from 5 to 6 December 2006. Surveys were carried out both on the lawns and reinforced paving slabs. Large building structures, presumably ruined bridge foundation, are marked in blue. River at this place is no more than 100 years. Large buried ...

  • ECSMGE CONFERENCE 2015: Managing the Clogging of Groundwater Wells

    This is the poster or summary of a paper being presented at the XVI ECSMGE  - European Conference on Soil Mechanics & Geotechnical Engineering - in Edinburgh from 13th to 17th September 2015. Groundwater wells are common to many civil engineering projects and their operational performance can play a crucial role. The wells may be part of a construction dewatering system, ...

  • Locate abandoned production abandoned well case study

    Clearwater, Florida Historical records discovered during construction of a commerical building indicated that a deep well with steel casing was likely present within a portion of the project site. Regulatory officials halted construction and insisted that the presence (or absence) of the well be confirmed. If the well was present, it was required that the well be exposed so that it could ...
