Solutions for the in-situ soil remediation

by The BioSolve Company     based in Lexington, MASSACHUSETTS (USA)

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 down gradient recovery wells or trenches.

Monitoring of VOCs in Porewater

by SORBISENSE     based in Tjele, DENMARK

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 Sorbisense sampling equipment with the proven technology of soil water samplers. With this combination, a practical new method is made available, which allows for monitoring the presence of porewater-dissolved VOCs above the groundwater table. This provides a significantly improved basis to define and determine the leaching risk to the groundwater, and thus allows for better and more cost-efficient decisions to prevent the pollution in reaching the groundwater.

A simple construction with multiple options

The application uses SorbiCell VOC combined with suction cells, soil water samplers. When installed correctly, and applied with the correct procedures, the suctions cells extract capillary bound water from the soil matrix. The system demands no other resource than a container that is put under vacuum. The vacuum in the container then ensures a flow through of the Sorbicell over a period of time, fx. 2-3 weeks. The method is highly suitable for monitoring a site over longer periods of time.

Mining & minerals solutions for acid mine drainage industry

by WesTech Engineering, Inc.     based in Salt Lake City, UTAH (USA)

Through the application of modern mining technologies, WesTech helps to assure that the byproducts of minerals extraction process are made inert, reliably contained and kept from causing environmental damage. Implementation of WesTech tailings processing technology assures protection of the groundwater, surface waters, wildlife and communities which in the past have been the victims of tailings dam leaks and levy failures.
