Abstract
A device and method for collecting sample fluids from an underground source which includes sample wells terminating in a corrugated conduit and sieve. The sampling regions for each sample well is separated by a grout or expanding seal barrier. Negative pressure is optionally applied to extract fluids from the underground matrix for sampling. The device can also be used for remediating an environmental contaminant from soil or aquifers. Upon identification of at least one environmental contaminant, a remediation composition is injected into the soil or aquifer using the sampling wells of the device. The remediation fluids can be directed to specific locations by selectively utilizing one or more sampling wells to inject the remediation fluid.
Claims20
An environmental well system, comprising:
- an elongated well conduit having a first end and a second end, the well conduit further including at least one well section and at least one non-well section;
- the well section having a plurality of perforations disposed through an outer lateral wall of the well conduit, thereby allowing fluid within the well conduit to pass through the perforations and exit the well conduit in a lateral direction;
- a sealant aperture disposed through the outer lateral wall of the well conduit;
- and
- a sealant line residing within the well conduit, the sealant line having a first end and a second end with the first end being angled towards and temporarily connected to the well conduit at a location that brings the sealant line into fluidic communication with the sealant aperture, such that sealant can be forced through the sealant line, and in turn, through the sealant aperture to create a seal, external to the well conduit, in a bore hole in which the well conduit resides.
An environmental well system, comprising:
- an elongated well conduit having a first end and a second end, the well conduit further including at least one well section;
- the well section having a plurality of perforations disposed through an outer lateral wall of the well conduit, thereby allowing fluid within the well conduit to pass through the perforations and exit the well conduit in a lateral direction;
- a sealant aperture disposed through the outer lateral wall of the well conduit in one of the non-well sections;
- a sealant line residing within the well conduit, the sealant line having a first end and a second end with the first end being temporarily connected to the well conduit at a location that brings the sealant line into fluidic communication with the sealant aperture, such that sealant can be forced through the sealant line, and in turn, through the sealant aperture to create a seal, external to the well conduit, in a bore hole in which the well conduit resides;
- and
- the connection of the sealant line to the well conduit being detachable, such that the sealant line can be removed from the well conduit after the seal has been created in the bore hole.
An environmental well system, comprising:
- an elongated well conduit having a first end and a second end, the well conduit further including a plurality of well sections, with a plurality of non-well sections;
- each well section having a plurality of perforations disposed through an outer lateral wall of the well conduit, thereby allowing fluid within the well conduit to pass through the perforations and exit the well conduit in a lateral direction;
- a plurality of sealant apertures, each sealant aperture disposed through the outer lateral wall of the well conduit proximate one of the non-well sections;
- a plurality of sealant lines residing within the well conduit, each sealant line having a first end and a second end with the first end being temporarily connected to the well conduit at a location that brings the sealant line into fluidic communication with one of the sealant apertures, such that sealant can be forced through the sealant line, and in turn, through the sealant aperture without discharging sealant into the well conduit thereby creating a seal, external to the well conduit, in a bore hole in which the well conduit resides;
- and
- the connections of the sealant lines to the well conduit being detachable, such that the sealant lines can be removed from the well conduit after the seals have been created in the bore hole.
