Our Soil and Groundwater Remediation System experience includes:
|
|
› Soil-vapor extraction systems to remediate soil impacted by volatile organic compounds (VOCs);
|
|
› Groundwater containment systems, including interceptor trenches, sparging, and reactive media walls for solvents, phenols, TPH, toxic metals and perchlorate;
|
|
› Groundwater treatment systems, including air stripping and carbon adsorption for chlorinated solvents and physical chemical treatment for groundwater impacted by metals;
|
|
› In-situ heating of soil and groundwater coupled with soil vapor extraction for VOCs;
|
|
› High-vacuum multi-phase extraction to treat soil containing petroleum and chlorinated hydrocarbons;
|
|
› Injection systems for treatment by chemical oxidation of BTEX, MTBE, TBA and naphthalene via Ozone, Hydrogen Peroxide, and Air.

Groundwater Treatment System Expansion, Sacramento California
As part of a multi-year contract with this aerospace contractor, our scope of services at this site included, connection of two additional extraction wells to an existing groundwater pump and treat system. Work included installation of submersible pumps, well vaults, transformer pads, bollards, fencing, and HDPE piping to connect the wells to an existing main pipeline header. Glacier excavated 4,500 feet of trench and installed two 4 inch and one 6 inch conduits to energize the new systems.

Gasworks Park, Seattle Washington
Installation of an in situ remediation system at this former coal gasification plant included connecting 49 air sparge wells to a treatment system using over 18,000 feet of small diameter HDPE pipe. Approximately 1,500 feet of 6-inch solid and perforated horizontal vapor extraction and conveyance piping was installed to recover hydrocarbon vapor. The pad mounted treatment system consists of a 500 cfm thermal/catalytic oxidizer, two 10 horsepower vapor extraction blowers, and a 30 horsepower sparge blower.

Air Sparge & Soil Vapor Extraction System, Tukwila Washington
These air sparging and soil vapor extraction systems for a former truck manufacturer in Seattle, Washington consist of 29 air sparge wells situated approximately 25 feet below the groundwater surface. Each well was piped individually to an equipment room where flow measurement and control is performed. During trenching approximately 1200 tons of soil contaminated with metals and VOC’s was excavated and transported to an off-site disposal facility.

Navel Submarine Base, Bangor Washington
At the Naval Submarine Base in Bangor, Washington, Glacier constructed a 300,000 GPD treatment plant for removal of volatile organic compounds from groundwater. The system components include influent and effluent flow equalization tanks, a 48 foot air stripping tower with a 5 hp blower system, solid filtration systems, and chemical injection to control mineral precipitation and biological growth throughout the treatment process; as well as modern computer technology allowing the system to be controlled and monitored remotely.
