1. Apparatus for delivery of remediation materials to underground contaminated soils and water, comprising:
- a water tank for holding water under pressure;
a remediation materials tank for holding remediation materials under pressure;
a compressor to deliver pressurized air to said water tank and to said remediation materials tank to pressurize said tanks;
a hollow cylindrical pipe for drilling to a site of underground contamination and for delivering remediation materials to the site of the underground contamination;
a pressure tip attached to one end of said hollow cylindrical pipe; and
means selectively connecting the water tank and remediation materials tank, respectively, to the hollow cylindrical pipe so that when the water tank is connected to the hollow cylindrical pipe, water under pressure flows from the water tank to the hollow cylindrical pipe and from the pressure tip as a pressurized stream, the pressurized stream being capable of drilling into ground to allow the hollow cylindrical pipe to be inserted into the ground behind the pressurized stream to the site of underground contamination, and when the remediation materials tank is connected to the hollow cylindrical pipe, remediation materials flow from the remediation materials tank to the hollow cylindrical pipe and from the pressure tip.

Abstract
An apparatus and method for delivery of remediation material to treat underground contaminated soils and water having a hollow cylindrical pipe through which both to apply water under air pressure and to deliver the remediation materials. Tanks of water, nutrients, and bacteria are typically mounted on the platform of a flat-bed truck or on a trailer which is transported by means of a hitch. A compressor is connected to the tanks of water, nutrients, and bacteria to provide pressurized air to create flow of water, nutrients, and bacteria from the tanks to the underground contaminated soils and water.

12. Apparatus for delivery of remediation materials to an underground site of contamination, comprising:
-
a source of pressurized drilling fluid; a source of pressurized remediation materials; a length of pipe for insertion into the ground from the surface to the site of contamination, the pipe having a forward end; means for selectively connecting the source of pressurized drilling fluid to the pipe so that when connected to the pipe the drilling fluid is forced, as a pressurized stream, from the forward end of the pipe, whereby the pressurized stream will drill a hole through the ground as the forward end of the pipe is inserted into the ground; and means for selectively connecting the source of remediation materials flow from the forward end of the pipe.

13. A method for delivery of remediation materials to underground contaminated soils and water comprising:
-
obtaining a length of hollow cylindrical pipe; forcing a drilling fluid as at least one high pressure stream from the forward end of the hollow cylindrical pipe into the ground adjacent to the forward end of the hollow cylindrical pipe to drill into such adjacent ground; continually inserting the pipe into the drilled adjacent ground to move the pipe into the ground toward an area of underground contamination and present new ground to be drilled adjacent to the forward end of the pipe until the site of contamination is reached by the forward end of the pipe; with the forward end of the pipe in the site of contamination, forcing remediation materials from the forward end of the pipe into the site of contamination. - View Dependent Claims (14, 15, 16, 17)
