Description

A sampling apparatus is described for monitoring vadose zones, geologic media or buried waste in sediment and more particularly to such an apparatus which is operable as an access port for geophysical logging and collecting fluid samples to permit analysis of such fluid samples for the presence of toxic substances, having a pipe-like, stainless steel, longitudinally extending, access tube with two ends, where the first end extends above the surface of the sediment and has a removable air tight seal. The subject invention further has a backing in fluid communication with the access tube and a fluid permeable plate contiguous ... continued below

Description

A sampling apparatus is described for monitoring vadose zones, geologic media or buried waste in sediment and more particularly to such an apparatus which is operable as an access port for geophysical logging and collecting fluid samples to permit analysis of such fluid samples for the presence of toxic substances, having a pipe-like, stainless steel, longitudinally extending, access tube with two ends, where the first end extends above the surface of the sediment and has a removable air tight seal. The subject invention further has a backing in fluid communication with the access tube and a fluid permeable plate contiguous with the backing, wherein the fluid permeable plate is made up of porous stainless steel. A reservoir is integrated into the second closed end of the access tube for containing the collected fluid. A vacuum pump, having a vacuum gauge/transducer attached thereto, is connected to the removable air tight seal for applying a vacuum to the access tube, such that gas and fluid samples may be drawn through the fluid permeable plate. A fluid sample connector coupled to the removable air tight seal, in addition to the vacuum pump with vacuum gauge/transducer, for withdrawing a fluid sample from the access tube.
