Enhanced Vapor Intrusion Mitigation via Horizontal Remediation Wells


Courtesy of Directional Technologies, Inc.

Vapor Intrusion (VI) is a potential concern at any building - existing or planned, located near soil or groundwater contaminated with volatile organic compounds (VOCs). Conventional installation technologies (vertical wells) can fall short, especially when large structures such as factories, hangars, and offices buildings are involved because they typically involve expensive and lengthy business disruptions. 

The solution is Horizontal Remediation Wells (HRWs) installed outside the building footprint. With HRWs, there is no need to disrupt business operations or move inventory, and the site restoration costs are minimal compared to vertical. Additionally, HRWs can provide better aerial subsurface coverage, ensuring that there are no “dead spots” where vapors can persist.
