Abstract:
A soil gas monitoring device comprising;a) a chamber having an elongated chamber housing with an upper open end and a lower open end; said lower open end removably coupled essentially airtight to the soil, b) a cover removably coupled using an essentially airtight elastic seal to said upper open end thereby forming a closed chamber, c) an intake port in said chamber housing, d) an exhaust port in said chamber housing, e) an exhaust manifold disposed in said chamber and removably connected to said exhaust port, f) a means for open circuit sampling said closed chamber for efflux gases during a selectable monitoring time via said exhaust manifold, said selectable monitoring time having a selectable recording time, g) a means for periodically removing said essentially airtight cover thereby exposing said chamber to ambient conditions, and h) a heat shield removably disposed on said cover.
