  • Horizontal Well Systems for Improving Remedial Efficiency and Zone of Influence

    To improve remediation efficiency and expand the zone of influence, Directional Technologies, Inc. transferred technology from the oil and gas industry to the environmental industry. The oil and gas industry has used directional drilling for decades to improve oil recovery, based on a simple concept that the more screen contact there is with the “pay-zone,” the more production gained. ...

  • Case study - Hydraulic slurry emplacement of potassium permanganate and zero valent iron for integrated site remediation

    Site Description: An active electronic manufacturing facility had an on-site TCE handling unit that was active for 10 years. During this time, approximately 1,365 gallons of solvent was released, which created an approximate 16 acre plume in saprolite and bedrock. Contaminants: Primarily TCE at concentrations greater than 200,000 ug/L in the source area with ...

  • What`s the Best Air Pollution Control Technology for My Process?

    Air pollution control equipment is not something that business owners address by saying, “Let’s do the right thing for the environment and install an oxidizer!” In fact, the scenario is more likely to be “We need to increase productivity (always a good thing!), but that will put us over our annual emissions limits. Do we know what we will need? Where do we start? Who can ...

  • Horizontal Directional Drilling - A Green and Sustainable Remediation Remedy

    Interest in using sustainable practices and technologies for environmental cleanup has increased notably within the past few years. The US EPA and many states have published recommended practices to reduce the environmental footprint of cleanup operations, and many consultants and contractors are attempting to “go green” in contaminated site remediation. It makes sense to conserve ...

  • Planning-Level Source Decay Models to Evaluate Impact of Source Depletion on Remediation Time Frame

    A recent United States Environmental Protection Agency (US EPA) Expert Panel on Dense Nonaqueous Phase Liquid (DNAPL) Source Remediation concluded that the decision-making process for implementing source depletion is hampered by quantitative uncertainties and that few useful predictive tools are currently available for evaluating the benefits. This article provides a new planning-level approach ...


  • The Time-Value of bioCycle

    BIOCYCLE’S 50th anniversary party in San Diego provides a perfect opportunity to write about the enormous contributions that have been made over the last five decades. Thinking about all the forward progress in organics utilization since 1960, I am humbled by the BioCycle legacy. To really appreciate the enormity of the biological utilization challenge 50 years ago, we need to reflect on what was ...

  • Tackling remediation emissions

    Organisations commissioning regeneration projects now have the option to substantially reduce the carbon emissions associated with any remediation project, while offsetting the remaining carbon impact of these works, says Joe Teer, operations director of QDS. QDS introduced a carbon neutral remediation (CNR) service earlier this year triggered at this particular time by the fact ...

The remediation ...


  • Recent papers in groundwater remediation

    Computational cost is a critical issue for large-scale water resource optimization under uncertainty, since time-intensive Monte Carlo simulations are often required to evaluate over multiple parameter realizations. This paper presents an efficient approach for replacing most Monte Carlo simulations with efficient surrogate models within a noisy genetic algorithm (GA). The surrogates are trained ...

  • Lake Jamno remediation proposal

    Lake Jamno………. near the city of Koszalin in Poland, has been contaminated by bio-mass sludge build-up from many years of agriculture run-off. Once a popular recreational and vacation destination, the Lake has been closed to swimming and boating since 2001. A Letter of Intent has been signed between the City of Koszalin and BluePlanet for the reclamation of Lake Jamno using an AQUACLEAN Treatment ...

  • Time-Tested Advantages of Horizontal Wells

    Wells are wells are wells, right? Both conventional vertical wells and directionally drilled horizontal wells have a screened casing that is connected to solid riser casing which leads to the ground surface. Groundwater or soil vapor is drawn through a well screen to remove contaminants. Remediation agents such as air, bioamendmnents or potassium permanganate are injected through a well screen to ...

  • Important Facts About Saltwater Remediation

    Soil that has suffered erosion due to salt, generally becomes useless to any kind of vegetation. This soil becomes crusty and if a lot of acreage is involved, it can cause upsets in ecosystems as well. While researchers have found some ways to treat these areas, the time those processes took were long and tedious. Thanks to today's technology for ...

  • Phytocapping: an alternative technique for landfill remediation

    An alternative technique of landfill remediation known as 'Phytocapping' was trialled at Rockhampton, Australia. Twenty one tree species were established on two types of phytocaps (thick cap; 1400 mm soil and thin cap; 700 mm). The trial was monitored for plant growth, transpiration loss, canopy rainfall interception and methane oxidation. The results show that the tree species can intercept ca. ...

  • Remediation of DNT drum disposal area.

    In 1991, an abandoned drum disposal area was discovered in a small ravine known as the Wash 3 tributary at the Apache Powder Superfund Site near Benson, Arizona. The 110-gallon steel drums were found to have been used to store 2,4- and 2,6-dinitrotoluene (DNT) that was purchased for experimental formulation of a composite explosive for the mining industry in the 1955 to early 1960's timeframe. ...
