Abstract: Provided herein is a method for flavoring an ingestible composition with an organoleptically effective amount of the flavoring agent. The flavoring agent may be used in a wide variety of ingestible vehicles such as chewing gum compositions, hard and soft confections, toothpaste, dairy products, beverage products including juice drinks and juice products, green vegetable and chicken products, salad dressings, deserts, bottled water, frozen treats and the like. The present invention also pertains to an ingestible composition comprising an ingestible vehicle and an organoleptically effective amount of the purified flavoring agent. The present invention also pertains to oxaloacetic acid and salts of oxaloacetic acid, represented by the formula, HOOCCH2CO—COOH and salts of the same. The invention further uses oxaloacetic acid and salts of oxaloacetic acid as a method to preservative in the preparation of ingestible compositions, without increase in toxicity.

Abstract: A system for the onsite storage, treatment and disposal of contaminated soils and sediments includes a trench that is excavated at the site. The trench is formed with a bottom surface that includes a sump reservoir and a sloped portion oriented to feed liquids into the sump reservoir. An impervious liner is positioned in the trench to prevent leakage into the surroundings. A sump system that includes the sump reservoir, drain tubes and geotextile netting is disposed in the trench to transfer fluids between the sump reservoir and the contaminated material. A geotextile filter sheet is positioned over the sump system allowing fluid transfer between the sump system and the contaminated material while preventing solids from entering the sump system. An access pipe allows fluids to be introduced into and withdrawn from the sump reservoir to accomplish various treatment methods including de-watering, vapor extraction, bioremediation, surfactant washing and solvent extraction.

Abstract: A process for removing solvent from soil and debris comprised of the steps of removing the solvent by soil vapor extraction and then washing the soil with a mixture of solvent eating bacteria, nutrients, and water is shown. The process decreases overall capital costs of solvent extraction systems, allows flexibility to size the equipment according to the needs at the individual clean-up site, allows for the purchase of "off the shelf" equipment, allows for easy transportation from site to site, operates more energy efficiently than current art, reduces material handling problems, and reduces the possibility of air emissions.
