US Patent:

6416250, Jul 9, 2002

Filed:

Oct 29, 1999

Appl. No.:

09/429878

Inventors:

Tyler Gilmore - Pasco WA
Daniel I. Kaplan - Aiken SC
George Last - Richland WA

Assignee:

Battelle Memorial Institute - Richland WA

International Classification:

B09C 108

US Classification:

4051285, 40512815, 40512875

Abstract:

A reagent delivery method includes positioning reagent delivery tubes in contact with soil. The tubes can include a wall that is permeable to a soil-modifying reagent. The method further includes supplying the reagent in the tubes, diffusing the reagent through the permeable wall and into the soil, and chemically modifying a selected component of the soil using the reagent. The tubes can be in subsurface contact with soil, including groundwater, and can be placed with directional drilling equipment independent of groundwater well casings. The soil-modifying reagent includes a variety of gases, liquids, colloids, and adsorbents that may be reactive or non-reactive with soil components. The method may be used inter alia to form reactive barriers, control pests, and enhance soil nutrients for microbes and plants.

Filed:

Mar 19, 1999

Appl. No.:

09/272761

Inventors:

Tyler J. Gilmore - Pasco WA
Kirk J. Cantrell - West Richland WA

Assignee:

Battelle Memorial Institute - Richland WA

International Classification:

G01N 122

US Classification:

436181, 436148, 422 681, 422 83, 422 99, 422102, 73 191, 73 1912, 96257

Abstract:

The present invention is an improvement to the method and apparatus for measuring volatile compounds in an aqueous solution. The apparatus is a chamber with sides and two ends, where the first end is closed. The chamber contains a solution volume of the aqueous solution and a gas that is trapped within the first end of the chamber above the solution volume. The gas defines a head space within the chamber above the solution volume. The chamber may also be a cup with the second end. open and facing down and submerged in the aqueous solution so that the gas defines the head space within the cup above the solution volume. The cup can also be entirely submerged in the aqueous solution. The second end of the. chamber may be closed such that the chamber can be used while resting on a flat surface such as a bench. The improvement is a sparger for mixing the gas with the solution volume.

International Classification:

B09C 108

US Classification:

4051285, 4051287, 40512875, 40512815

Abstract:

A method of treating soil contamination by forming one or more zones of oxidized material in the path of percolating groundwater is disclosed. The zone or barrier region is formed by delivering an oxidizing agent into the ground for reaction with an existing soil component. The oxidizing agent modifies the existing soil component creating the oxidized zone. Subsequently when soil contaminates migrate into the zone, the oxidized material is available to react with the contaminates and degrade them into benign products. The existing soil component can be an oxidizable mineral such as manganese, and the oxidizing agent can be ozone gas or hydrogen peroxide. Soil contaminates can be volatile organic compounds. Oxidized barriers can be used single or in combination with other barriers.
