A device and method for collecting liquid from an underground source or remediating an environmental contaminant from soil or aquifers. The device includes injection tubing having one or more holes, disposed within a corrugated conduit and sieve. An injection channel is provided on the corrugated conduit allowing liquid to flow around the injection system. The injection system can be used in vertical or horizontal well settings. The device is inserted into contaminated soil or an aquifer, and a remediation composition is injected into the soil or aquifer using the injection tubing of the device. One or more of the devices are placed into a well bore, with multiple devices allowing for adaptive, directional injection of the remediation composition.

1. An injection system, comprising: a sieve having an upper end and a lower end and an interior lumen, wherein the sieve is made of flexible or semi-flexible material;a corrugated conduit disposed in the interior lumen of the sieve, wherein the corrugated conduit has a plurality of peaks formed of a plurality of external ribs and troughs formed of a plurality of internal ribs;wherein the plurality of peaks and troughs are disposed perpendicular to the longitudinal axis of the corrugated conduit, and wherein the corrugated conduit has an interior lumen;at least one injection channel formed on the outer surface of the corrugated conduit and running parallel to the longest axis of the corrugated conduit, wherein the at least one injection channel is formed from removal of the plurality of external ribs of the corrugated conduit;an injection tubing disposed in the interior lumen of the corrugated conduit, having a matrix end and a surface end;wherein the injection tubing has at least one injection hole disposed in the tubing wall; andan injection cap disposed on the matrix end of the injection tubing, thereby restricting injected fluids from exiting the matrix end of the injection tubing. 2. The injection system of claim 1, wherein the sieve is a geotextile sock, wire mesh, or stainless steel screen. 3. The injection system of claim 2, wherein the sieve is a polyester geotextile sock. 4. The injection system of claim 1, wherein the corrugated conduit is high density poly ethylene, low density polyethylene, a composite of high density poly ethylene and low density polyethylene, steel, rubber, or polyvinyl chloride or plastic. 5. The injection system of claim 4, wherein the corrugated conduit is low density polyethylene. 6. The injection system of claim 1, wherein the corrugated conduit has a thickness measured from the peak of the external rib of the corrugated conduit to the trough of the internal rib of the corrugated conduit, and wherein the at least one injection channel is formed by partially removing the exterior ¼ to ½ thickness of the external rib. 7. The injection system of claim 1, wherein the at least one injection hole is about 3/32 inches in diameter. 8. The injection system of claim 1, further including a plurality of injection holes, each injection hole being disposed at between 1 hole per foot and 5 holes per foot. 9. The injection system of claim 1, further including a plurality of injection holes, each injection hole being equally spaced along the distance of the injection tubing. 10. The injection system of claim 1, further comprising an injection system or injection pump in fluid communication with the surface end of the injection tubing, where the injection system or injection pump is a positive displacement pump, a diaphragm pumps, a screw pump, a metering pump, a piston, a pump, a centrifugal pump, a jet pump, or an electric diaphragm pump. 11. The injection system of claim 1, wherein the injection tubing is high density poly ethylene, low density polyethylene, a composite of high density poly ethylene and low density polyethylene, a polyvinylidene fluoride resin, flexible steel, rubber lines, polyvinyl chloride, or plastic. 12. The injection system of claim 11, wherein the injection tubing is high density polyethylene tubing. 13. The injection system of claim 1, further comprising a strap or tie wrap disposed on the lower end of the sieve. 14. The injection system of claim 13, wherein the strap or tie wrap is steel, plastic, or metal band. 15. The injection system of claim 1, further comprising a strap or tie wrap disposed on the upper end of the sieve, wherein the upper end of the sieve surrounds the injection tubing. 16. The injection system of claim 15, wherein the strap or tie wrap is steel, plastic, or metal band. 17. A method of remediating an environmental contaminant, comprising: providing at least one injection system, comprising: a sieve having an upper end and a lower end and an interior lumen, wherein the sieve is made of flexible or semi-flexible material;a corrugated conduit disposed in the interior lumen of the sieve, wherein the corrugated conduit has a plurality of peaks formed of a plurality of external ribs and troughs formed of a plurality of internal ribs;wherein the plurality of peaks and troughs are disposed perpendicular to the longitudinal axis of the corrugated conduit, and wherein the corrugated conduit has an interior lumen;at least one injection channel formed on the outer surface of the corrugated conduit and running parallel to the longest axis of the corrugated conduit, wherein the at least one injection channel is formed from removal of the plurality of external ribs of the corrugated conduit;an injection tubing disposed in the interior lumen of the corrugated conduit, having a matrix end and a surface end; wherein the injection tubing has at least one injection hole disposed in the tubing wall;an injection cap disposed on the matrix end of the injection tubing;providing a vertical or horizontal bore hole;inserting the at least one injection system into the bore hole; andremediating the contaminant, wherein the remediation is accomplished through remediator injection or contaminant extraction. 18. The method of claim 17, wherein the carrier liquid is water. 19. The method of claim 17, further comprising injecting the carrier and remediator into the soil. 20. The method of claim 17, further comprising providing a plurality of injection systems into a single bore hole. 21. The method of claim 20, wherein up to eleven injection systems are inserted into the single bore hole. 22. The method of claim 17, wherein the negative pressure source is a pump. 23. The method of 17, further including providing a seal on either side of the sieve. 24. A method of collecting data on contaminant concentration and location in a subsurface matrix, comprising: providing at least one injection system, comprising: a sieve having an upper end and a lower end and an interior lumen, wherein the sieve is made of flexible or semi-flexible material;a corrugated conduit disposed in the interior lumen of the sieve, wherein the corrugated conduit has a plurality of peaks formed of a plurality of external ribs and troughs formed of a plurality of internal ribs;wherein the plurality of peaks and troughs are disposed perpendicular to the longitudinal axis of the corrugated conduit, and wherein the corrugated conduit has an interior lumen;at least one injection channel formed on the outer surface of the corrugated conduit and running parallel to the longest axis of the corrugated conduit, wherein the at least one injection channel is formed from removal of the plurality of external ribs of the corrugated conduit;an injection tubing disposed in the interior lumen of the corrugated conduit, having a matrix end and a surface end; wherein the injection tubing has at least one injection hole disposed in the tubing wall;an injection cap disposed on the matrix end of the injection tubing;providing a vertical or horizontal bore hole;inserting an injection system into the bore hole;extracting a sample from the subsurface matrix; andsubjecting the sample to chemical testing to determine presence and concentration of a contaminant.
