    Air pollution control for the remediation industry

    The remediation division of Anguil Environmental Systems (formerly known as Global Technologies) is focused on treating emissions and water contaminants extracted from below the earths` surface.  Formed shortly after the 1990 Clean Air Act targeted emissions associated with the extraction of polluted compounds from contaminated sites, Global subsurface remediation equipment has been successfully applied on contaminated sites in North and...

    TPH in Soil Remediation

    InfraCal TOG/TPH Analyzers allow for TPH (Total Petroleum Hydrocarbons) in soil testing at remediation sites such as leaking underground storage tanks and produced water evaporation ponds. Site managers can avoid having costly soil remediation equipment sit idle while waiting for off-site lab results. Sampling requires a few simple steps that can be performed by non-technical personnel. The soil is mixed with the extraction solvent, shaken, filtered, and then presented to the InfraCal Analyzer for measurement....

  • Monitoring of VOCs in Porewater

    Monitoring VOCs in porewater in the unsaturated zone is now possible.

    Sorbisense regularly offers new options for using the patented Sorbicell, which is used to monitor surface water, wastewater and groundwater.

    The latest is almost as “ground-breaking” as the SorbiCell itself. Until now it has been difficult, if not impossible, to directly monitor for volatile substances in pore water in the unsaturated zone. But the environmental consultancy firm Ejlskov A/S in Aarhus combined the use of...

  • Solutions for the in-situ soil remediation

    For over twenty years, BioSolve Pinkwater has been used for Surfactant Enhanced Remediation (SER) to mobilize and solubilize residual NAPL[i], facilitating its recovery and disposal. Depending on soil and plume characteristics, Pinkwater solution can reach contaminated zones through deep injection wells or be gravity fed from surface level injection galleries. After desorbing residual NAPL from soil surfaces on contact, Pinkwater then solubilizes the hydrocarbons in an aqueous emulsion, enabling extraction at...

  • Horizontal Remediation Well Systems

    Horizontal wells are a proven and effective remedial technology for site cleanup. For environmental applications, horizontal wells offer several advantages in comparison to traditional vertical wells. The first horizontal wells were installed using a mid-sized directional drill rig in 1993 by Directional Technologies, Inc. The three (3) horizontal Soil Vapor Extraction wells installed at John F. Kennedy International Airport was the beginning of a new industry. Directional Technologies, Inc. founders transferred...

    Oil in Water Analysis for Flowback or Produced Water

    The amount of water used in and produced by hydraulic fracturing of shale gas wells is in the millions of gallons per well. Whether the water is going to be taken off site for disposal or reused for re-injection, the flowback or produced water needs pretreatment to remove any residual oil from the water. Waiting for remote lab results can take several days to a week. InfraCal TOG/TPH Analyzers allow for oil in water testing at the well site in less than 10 minutes. The sampling requires a few simple steps that...
