  • How much does a Horizontal Remediation Well cost?

    In the early days of horizontal remediation wells, the estimated costs made many projects completely unfeasible. However, with the advance of technology in directional drilling and innovative solutions within the environmental industry, this technology is becoming affordable and practical. Like most environmental projects, the cost of a Horizontal Remediation Well will depend on the size and ...

  • The Phase 1 Environmental Assessment

    In today’s world where every property is subject to potential environmental risks a Phase 1 Environmental Site Assessment or ESA is an appropriate action to take. An ESA can help determine if the property has been contaminated by previous or current activities. The ESA can help protect the purchaser of a property from environmental risks prior to the closing on a property.  Lenders ...

  • Horizontal Remediation Wells - Don`t Disrupt your Client`s Business

    The use of Horizontal Remediation Wells for environmental cleanup is a proven solution for project managers with many benefits including the benefit of the continuation of business activities during mitigation or remediation activities.   Since 1993, Directional Technologies, Inc. has installed thousands of Horizontal Remediation Well systems in the United States and abroad at many different ...

  • Multipurpose Horizontal Remediation Wells Treat Impacts from Former DOD Operations

    The site, a former DOD plant previously used for the manufacture of aircraft and missile systems had TCE impacts that posed a threat to the current occupants at the site.    The site had been recently redeveloped into an industrial complex for several companies. For the new occupants, a disruptive indoor construction to install a vertical remediation system was out of the question. In ...

  • The Effectiveness of Using Automated Belt Oil Skimmers as a Method of Well Remediation

     ABSTRACT In many sites across the country, groundwater has been contaminated by petroleum products due to leaky underground tanks or past spills. If the leak has gone unnoticed, a considerable amount of product could exist in an aquifer (underground water reservoir), and may be trapped in the surrounding rock. Remediation can take months or years to complete and is frequently labor ...

  • DTI installs 3 blind horizontal remediation wells in cobble

    The Issue An active retail gas station next to a wetland area has benzene and trimethylbenzene plumes in a water table aquifer containing sand, gravel and cobbles. Rock fragments and boulders several feet in diameter lie in the vadose zone, between the ground surface and the water table. Business at the gas station would slow down or stop for an extended period of time if a vertical ...

  • DTI installs horizontal remediation wells under busy intersection

    The Issue A retail gasoline station in Tallahassee Florida with leaking underground storage tanks sits atop a local groundwater divide, causing petroleum hydrocarbon plumes to migrate in opposite directions from the site. In one direction, the plume has migrated under a residential neighborhood on downward sloping terrain, and in the opposite direction, the plume has migrated under a ...

  • Enhanced Vapor Intrusion Mitigation via Horizontal Remediation Wells

    Vapor Intrusion (VI) is a potential concern at any building - existing or planned, located near soil or groundwater contaminated with volatile organic compounds (VOCs). Conventional installation technologies (vertical wells) can fall short, especially when large structures such as factories, hangars, and offices buildings are involved because they typically involve expensive and lengthy ...

  • Horizontal Remediation Wells used in order to preserve military security

    Project Description: Remediate a plume of trichloroethylene (TCE) under multiple military buildings by air sparging (AS) and soil vapor extraction (SVE). There are two target zones: the shallow zone is approximately 70' below grounds surface (bgs) and 20' below this is the deep zone. The plume was located under multiple buildings comprising an area of approximately 150,000 SF. Scope of Work: ...

  • Multifunctional Well Implemented for In Situ Remediation of Hydrocarbon Contaminations in Soil and Groundwater

    Abstract A recently developed Multifunctional Well has been implemented for the remediation of subsurface contamination caused by hydrocarbon spills. Four different remediation processes can be operated within the same well. At optimal efficiency of each remediation process, successive treatment of the capillary fringes, the vadose zone, and the aquifer can be accomplished. Each treatment ...


  • 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, ...

  • Sustainable remediation

    The term remediation refers to procedures implemented to eliminate contaminants and toxic waste from polluted landfills, water bodies and other places to promote environmental health and safety. Since its inception in the 1970s, remediation itself has evolved into a full-fledged industry. Organizations engaged in environmental construction activities typically execute remediation projects. In ...

  • Horizontal Wells - Technology Overview

    Horizontal well technology has been incorporated into many current environmental remediation applications (and associated contaminants), such as in situ bioremediation, air sparging, vacuum extraction, soil flushing, free product recovery, etc. Ac cording to information reviewed, this technology is most applicable to sites with relatively shallow soil and/or groundwater contamination, and can ...

  • Well oiled machines

    On November 1, 2004, Bridgewater's first oil skimmer began removing oil from its mill drains. At a cost of $6,500, the skimmer, supplied by Abanaki UK Ltd, represents a significant investment and underlies Bridgewater's commitment to enhancing the operation of its Effluent Treatment Plant. The acquisition of an oil skimmer materialized following lengthy periods of under performance from a ...

  • 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, ...

  • 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 ...

  • 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 ...
