Remtech is an Environmental Remediation and General Construction firm with offices in Spokane Washington and Ridgefield Washington, near Portland Oregon.
Remtech has successfully completed environmental remediation projects throughout the world, from remote areas of Alaska to the continent of Africa. Since Remtech`s incorporation in 1990, it has built a solid reputation for responsiveness and technical excellence in a wide variety of construction and remediation services.
Remtech is one of the oldest and most experienced thermal remediation firms in the nation, and is widely recognized as one of the leading environmental remediation service firms in the Pacific Northwest. In addition to thermal desorption, Remtech`s expertise includes soil stabilization, bioremediation, habitat restoration, operation and maintenance of groundwater treatment systems, and construction of hydraulic cut-off walls.
Environmental Remediation Services
Remtech has performed numerous environmental remediation projects, on time, and under budget. With experienced personnel on staff, and a variety of company-owned equipment, Remtech is a very cost-effective solution to your environmental needs.
Remtech has performed numerous large and sensitive environmental remediation and excavation projects in residential, commercial, and industrial settings. These projects involved implementing erosion and dust control measures, as well as measures designed to prevent potential cross-contamination.
Remtech provides a wide variety of environmental remediation services to both public and private sector clients, including:
Thermal Desorption
Thermal Desorption or low temperature thermal desorption (LTTD), also known as low temperature thermal volatilization, thermal stripping, and soil roasting, is an ex-situ remedial technology that uses heat to physically separate petroleum hydrocarbons from excavated soils. More info
Thermal Oxidation
Thermal Oxidation is accomplished by heating the contaminated off-gas stream by direct exposure to a fossil fuel flame. The air is preheated, thoroughly mixed, and combusted at high temperatures so that organics burn to form carbon dioxide and water. More info
LTTD Services
LTTD, or Low Temperature Thermal Desorption separates contaminants from soil. Soil is heated in a chamber in which water, organic contaminants and certain metals are vaporized. A gas or vacuum system transports vaporized water and contaminants to an off-gas (i.e., air emission) treatment system. More info
Thermal Remediation Equipment Manufacturing
Remtech Inc provides the thermal remediation equipment industry with high quality and economically priced custom engineered equipment. More info
Soil Flushing
In situ soil flushing is an innovative treatment technology that floods contaminated soils with a solution that moves the contaminants to an area where they are removed. “In situ" meaning “in place” refers to treating the contaminated soil without digging up or removing it. More info
Bioremediation
Bioremediation is a treatment process that uses microorganisms (yeast, fungi, or bacteria) to break down, or degrade, hazardous substances into less toxic or nontoxic substances. More info
Phytoremediation
Phytoremediation is implemented by establishing a plant or community of plants that have been selected to provide the required remediation mechanisms. The technology exploits the natural hydraulic and metabolic processes of plants, and thus is passive and solar driven. The technology can be used in combination with mechanical treatment methods or as a "stand alone" treatment method. More info
Bioslurping
Vacuum-enhanced recovery (Bioslurping) is performed using a tube positioned in a well so the end of the tube is near the water-table level in the formation. Vacuum is applied to the well using a single aboveground vacuum pump, and LNAPL and groundwater are removed from the well by air entrainment. More info
Slurry Walls
Slurry wall subsurface barriers consist of vertically excavated trenches filled with slurry. The slurry, usually a mixture of bentonite and water, hydraulically shores the trench to prevent collapse and retards ground water flow. More info
Contaminated Soil Disposal
Remtech's contaminated soil disposal facility was permitted to store up to 45,000 cubic yards of contaminated soil. The contaminated soil disposal facility consisted, in successive layers, of bedding sand, an impermeable composite liner, crushed gravel and asphalt. More info
Soil Treatment
Thermal desorption soil treatment is a phrase applied to many different types of soil treatment technologies. All of these soil treatment technologies consist fundamentally of a two-step process, heat is applied to a contaminated material, such as soil, sediment, sludge, or filter cake, to vaporize the contaminants into a gas stream that, in Step 2, is treated to meet regulatory requirements prior to discharge. More info
PCB Remediation
Remtech has conducted PCB remediation of contaminated soil at numerous sites where soil became contaminated. Projects completed by Remtech that involved remediation include many different environments and situations, including but not limited to: residential yards, superfund sites, former fuel sites, former wood treatment plants, former Air Force and Navy bases or drilling operations, including work sites above the Arctic Circle. More info
Groundwater Treatment
Remtech operated and maintained a 1,300 gallon per minute groundwater treatment plant a site identified as the Explosives Washout Lagoon Groundwater Operable Unit Three, located in the east-central portion of UMCD. At one time, the site consisted of two adjacent unlined lagoons, each approximately 25 by 75 feet and 6 feet deep. The lagoons were used for infiltration of wastewater from the Explosive Washout Plant during the 1950s and 1960s. During their operation, the lagoons received approximately 85 million gallons of wastewater containing high concentrations of explosives. More info
Habitat Restoration and Containment
Remtech was contracted by the National Oceanic Atmospheric Administration to perform stream habitat rehabilitation at two separate locations within Commencement Bay. The purpose of this project was to reestablish a habitat that allowed for the reintroduction of aquatic wildlife. More info
