Vapor Mitigation: Farallon's Newest Service

Farallon Now Installs Sub-Slab Depressurization Systems for Indoor Air Contamination

Indoor air impacts in buildings where soil and groundwater contamination exists in the subsurface have become an increasing concern in Washington and Oregon in recent years.  In many cases, indoor air quality in occupied buildings has been impacted by subsurface contaminants at levels that require mitigation while cleanup actions are implemented at the site.  Farallon understands the sensitivity of indoor air quality issues and has installed mitigation systems that prevent contaminants from entering buildings with minimal impacts to ongoing operations.

Farallon now offers turnkey vapor intrusion services that include installation of vapor mitigation systems in addition to site evaluation and regulatory negotiation to determine whether vapor mitigation is necessary to protect indoor air quality.  The sub-slab depressurization systems installed by Farallon have proven highly effective in mitigating the migration of contaminant vapors from beneath a building slab into indoor air.  These systems are designed to be an unobtrusive, affordable method to extract contaminant vapors from beneath buildings and safely discharge them away from occupants.

Farallon’s Engineering Group designs and installs sub-slab depressurization systems in buildings of all types in a manner that integrates with existing building infrastructure.  These systems typically are installed in combination with Farallon’s patented sub-slab monitoring probes to obtain data demonstrating system effectiveness in preventing contaminants from affecting indoor air.  Farallon also can incorporate sub-slab depressurization systems into building plans for future construction on or near contaminated properties where vapor intrusion is a known risk.

Farallon has successfully designed and installed sub-slab depressurization systems at multiple commercial and industrial facilities in the Pacific Northwest, including national restaurant chain locations, retail membership warehouses, strip mall facilities, and office buildings.

If you are involved with a site with underlying volatile contaminants in soil or groundwater and require a vapor intrusion assessment or mitigation of a confirmed indoor air quality issue, Farallon would be happy to discuss your situation and suggest turnkey options to resolve the matter in a discreet and cost-effective manner.
