Green Technologies for the Environment.

G'Day from South Australia! Representing VeruTEK, I have made my way down under to aid the setup and design for treatability/laboratory dosage studies to be performed at CRC CARE, one of VeruTEK's Australian federal research collaborators. Co-located with the Centre for Environmental Risk Assessment and Remediation (CERAR) in the new multi-million dollar purpose built facilities at the Mawson Lakes Campus of the University of South Australia, CRC CARE aims to bring together the foremost expertise in science, industry and government in a partnership for the development, commercialization and extension of advanced technologies and methods.

Over the next two weeks, I will guide CRC CARE scientists through VeruTEK's treatability/laboratory dosage study to treat contaminated soil associated with an Australian Federal Defense Site.

The basic steps of treatability include:

1. 1. Initial Characterization of Site Samples
2. 2. Supplemental Surfactant Screening
3. 3. Desorption/Solubilization Enhancement of Target Contaminants from Site Sample
4. 4. Oxidation of Desorbed/Solubilized Target Contaminants with S-ISCO
5. 5. Soil Columns to Simulate S-ISCO Field Treatment

Based on results from the treatability/laboratory dosage study, CRC CARE and VeruTEK can design a pilot- or full-scale field implementation schedule to remedy the Defense Site.

The collaborative work being done between VeruTEK and CRC CARE represents one of VeruTEK's many projects expanding green chemistry and the S-ISCO technology platform for global environmental remediation.

Groundwater samples were collected from a former industrial manufacturing facility with moderate FREON-113 and
chlorinated hydrocarbon contamination. These samples were characterized to determine initial FREON-113 and other
volatile compound contamination levels prior to using in three laboratory tests:
• Test 1: No treatment (control)
• Test 2: Alkaline persulfate
• Test 3: Fe-EDTA Catalyzed Persulfate

Soil samples were collected from a farm with moderate pesticide contamination. These samples were characterized to determine initial pesticide contamination levels prior to using in three laboratory tests:
• Test 1: No treatment (control column)
• Test 2: Alkaline persulfate and VeruSOL™
• Test 3: Iron-activated persulfate with VeruSOL™
Each test contained the same amount of soil and groundwater. Each test also contained approximately the same amount of contaminants initially; the table and graph below demonstrate the effectiveness of S-ISCO in destroying pesticide contamination after just 7 days:

VeruTEK Technologies, Inc. (VTKT.OB) provides proprietary, patent-pending, green nanotechnology solutions for cleaning up the environment.  The Company's S-ISCO™ and S-ESCO™ solutions treat soil contamination "in place" eliminating the need for costly excavation and enabling custom remedies for individual sites. VeruTEK works with environmental consulting firms, government agencies and large corporations such as manufacturers, chemical companies and railroads to implement site-specific remedies that are environmentally safe and non-intrusive to the nearby community. The Company's mission is to help create a sustainable environment for future generations.

VeruTEK Technologies, Inc. (VeruTEK) performed a large-scale green remediation field test. The test focused on treatment of subsurface coal tar at a former Manufactured Gas Plant with VeruTEK's Coelution TechnologyTM, surfactant-enhanced in-situ chemical oxidation (S-ISCOTM). The test results exceeded expectations. Greater than 4 times the test designed soil contamination was destroyed and the test achieved a sustainable reduction in groundwater contamination.

Traditional ISCO methods have had limited success in degrading non-aqueous phase liquids (NAPLs) because of mass transfer limitations controlling the rate of dissolution of NAPL constituents into groundwater. In Situ Chemical Oxidation (ISCO) reactions predominantly take place in the aqueous phase in the subsurface. Treatability studies andfield verification pilot-studies have been conducted to evaluate the effectiveness of a new type of Coelution Technology®, Surfactant-Enhanced.

In-situ chemical oxidation has been shown to be an effective approach for treating volatile organics compounds (VOCs) and polycyclic aromatic hydrocarbons (PAHs) in lightly contaminated soil and groundwater at former manufactured gas plant (MGP) sites.

According to USEPA (2004), Cleaning up the Nation's Waste Sites, an estimated 294,000 contaminated sites will need to be cleaned up. The estimated cost to clean up these sites is about $209 billion. Many of these sites contain Non Aqueous Phase Liquids (NAPLs), which VeruTEK's technology specifically remedies. NAPL may be dense or light with respect to the density of water, approximately 1.0 gm/ml at 25º deg. C.

Green technologies for environmental cleanup provide unique opportunities for green job creation, enhancement of the health and well‐being of the nation. This stimulus would not only provide dollars for cleanup of environmental contamination on federal lands and facilities, but for Superfund Sites, our nation's vast legacy of industrial contamination.
