Vapor intrusion and population exposures to toxic or hazardous
materials are commonly regulated by local health authorities and
permitting agencies. The transport of vapors in various
subsurface soil and into the vicinity of permeable structures
provides a pathway of exposure to toxic and hazardous
materials. RTP staff have conducted surveys to identify
vapor intrusion and worked with engineering groups to provide
solutions that mitigate exposures to sensitive receptors.
Since the problems are usually localized and specific to
individual projects, a detailed discussion of the issues and the
potential solutions or mitigative measures would then be
recommended. You should contact your local RTP office to
obtain information on the solutions RTP can provide.
