Filed:

Feb 29, 2008

Appl. No.:

12/072802

Inventors:

Daniel T. Rogers - Geneva IL, US
Martin M. Kaufman - Commerce MI, US
Kent S. Murray - Dearborn MI, US

International Classification:

G06F 19/00

US Classification:

702 22

Abstract:

A method of calculating a soil contaminant risk factor for a chemical released into the environment is provided. The method comprises the steps of determining the toxicity value (T) of the chemical, determining the mobility (M) of the chemical in the soil where the chemical was released, determining the persistence value (P) of the chemical, and calculating the soil contaminant risk factor (SCRF) using the formula

Abstract:

A multi-level fluid transfer system, apparatus and process. In one well bore hole, there are multiple fluid transfer devices positioned to inject a fluid, such as air, at multiple levels in the well bore hole. There are seals between the levels establishing multiple compartments. Each fluid transfer device has an outlet in one of the compartments. The fluid transfer devices are connected to receive the fluid, which is transmitted into the well bore hole and released within the multiple compartments of the well bore hole. The fluid travels out of the well bore hole compartments in separate streams at different levels or depths and out into the contaminated ground. The multiple levels in the injection well allow for release of the fluid both above and below any lenses or areas of low permeability in the ground, to improve the efficacy of the remediation process. The multiple fluid transfer devices may be assembled into an apparatus with concentric riser conduits. The apparatus, system and method may be used for injecting a biological agent, for injection of an oxidant, and for injection of a sparging gas such as air.
