Introducing EZVI
A+ Environmental Solutions, LLC (AES) has the specialized knowledge and expertise to provide the most up-to-date, advanced solutions available for Phase III environmental bioremediation.
One of the main reasons environmental cleanup of chlorinated solvent contamination has historically been so difficult is the unique physical nature of PCE and similar chemicals. To combat this, scientists with the National Aeronautics and Space Administration (NASA) developed an Emulsified Zero-Valent Iron (EZVI) solution. They found that by injecting the EZVI solution directly into groundwater aquifers, it quickly reacted with the PCE and effectively destroyed it in place.
EZVI is composed of a food-grade surfactant, vegetable oil, water, and Zero-Valent Iron (ZVI) particles. When mixed together, ZVI particles are contained in water, and surrounded by an oil-liquid membrane. This membrane has physical characteristics similar to PCE, thus allowing EZVI to thoroughly mix with and destroy the PCE directly in place.1 This method of cleanup is called in-situ (in-place) remediation.
Recently, in-situ treatment methods have gained popularity as an environmental remediation strategy. And now, thanks to NASA’s groundbreaking technology, in-situ remediation using EZVI is clearly the most cost-effective and time-efficient method of PCE remediation for many sites. Compared to traditional treatment technologies, which can take years or even decades to remediate PCE contamination, EZVI has proven to clean up sites in as little as two to three months.2
In fact, the new treatment technology is so effective it has won the NASA 2005 Government Invention of the Year Award, NASA 2005 Commercial Invention of the Year Award, and the 2006 Award for Excellence in Technology Transfer (Federal Laboratory Consortium). In addition, EZVI was inducted into the NASA 2007 Technology Hall of Fame.2
AES is proud to be one of only seven companies in the nation to be licensed by NASA to produce and implement EZVI technology. We are the only firm on the West Coast to receive this privilege.
AES has two mobile soil and groundwater in-situ remediation trailers ready to be rapidly mobilized. While many consultants still dabble in out-dated and ineffective mitigation strategies, AES is always on the cutting edge of the newest, most effective remediation technologies. Our team of scientists and certified workers clean up chemically-impacted soil and groundwater quickly and efficiently. We have saved our clients millions of dollars, cleaned up, and closed sites where others have said it was not possible to do so.
In our 18 years of experience, AES has excavated and transported chemically-impacted soils. We have designed, built, and installed vapor extraction, UV ozone, thermal desorption, air strippers, bio-reactors, and pump-and-treat systems. These systems have their uses, but are mostly out-dated, expensive, and less effective than in-situ chemical oxidation and bioremediation. AES has, and continues to search out the most effective methods of treating chemically-impacted soil and groundwater.
The AES team is expert in putting the appropriate agents in contact with chemically-impacted soil and groundwater. We have the equipment and skill for hydraulic and pneumatic fracturing of soil structures to penetrate geologic formations for treatment and effective cleanup.
AES has state-of-the-art, cutting-edge know-how and equipment to clean up a wide variety of chemicals in soil and groundwater. We are frequent attendees and presenters at environmental conferences to stay abreast of the newest technologies.
