  • Why Your Project Should Include Articulated Concrete Blocks

    During any construction project, large or small, planning for potential construction erosion is essential. Failing to take into consideration the possibility of erosion when planning a construction site will not only reduce the quality of the soil at the site, but it may also damage surrounding properties, harm the local environment and result in hefty fines and liability costs. To avoid the ...

  • Shredding tyres stops zika virus breeding

    Zika is a dangerous disease threatening millions of people today in southern hemisphere. It is spread mostly by the bite of an infected Aedes species mosquito (Ae. aegypti and Ae. albopictus). These mosquitoes bite during the day and night. Once you get bitten it is too late to do much but what is important is to prevent this mosquito from breeding. Mosquitos typically lay eggs near water because ...

Alternative water supplies include brackish water sources that must be converted to potable water using desalination ...

  • 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, ...

  • Rain water meets thermal water – Drainage system in wellness-oasis

    The new “Kristall swim and health spa” in Ludwigsfelde is going to be the “finest spa resort” in Europe, the investor believes. On 4 November 2005, only five months after laying the foundation, the work was finished. The celebration crown was mounted on top of the wooden frame for the transparent dome roof, under which visitors will enjoy Mediterranean wellness delights. 300,000 visitors are ...

  • The Effects That Well Depth and Wellhead Protection Have on Bacterial Contamination of Private Water Wells in the Estes Park Valley, Colorado

    Over the past five years, it is estimated that 10% of residential water wells have tested positive for total coliform and 2% for E.coli bacteria in the Estes Park Valley, Colorado. Many of these water wells are shallow or hand-dug in construction. In this study, samplings of 30 private untreated water wells were tested for total coliform bacteria in the Estes Park Valley. Water wells were ...

  • 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. ...


  • Treatment of polluted river water by a new constructed wetland

    Abstract: A new constructed wetland was built to purify one polluted river in Taiwan, and this study was conducted to evaluate the treatment efficiency of the wetland. Due to the very limitation of available budget, several water quality items, which were stipulated by Taiwan’s Environmental Protection Administration for rivers, in the influent and effluent of wetland were analyzed and ...

  • 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 ...


  • 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 ...

  • 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 ...

  • 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 ...

  • Hydrochemical investigation of water from the Pleistocene wells and springs, Jericho area, Palestine

    Rising salinity levels is one of the significant signs of water-quality degradation in groundwater. The alluvial Pleistocene wells in the Jericho area, Palestine show high salinity and a high susceptibility to contamination. Future exploitation and management of the water resources under these conditions will require an in-depth understanding of the sources and mechanisms of contamination. The ...
