Innovative Groundwater Remediation Treatment Technology Commissioned

Pleasant Hill, CA - An innovative treatment technology is now being commissioned at a groundwater remediation site in Mountain View, California. 1,4-Dioxane, a pollutant recently identified in a decades-old groundwater contamination plume, will be removed using HiPOx™;, the innovative, commercially proven treatment system that destroys contaminants onsite. In addition to destroying the newly discovered 1,4-dioxane—a compound that can not be removed with conventional air stripping or carbon technology—the treatment system will be used to remove solvent contamination that responsible parties have been treating at the site for a number of years.

APPLIED PROCESS TECHNOLOGY, INC. ("Applied") was awarded a contract earlier this year to treat groundwater contaminated with 1,4-dioxane at a site located within the Middlefield-Ellis-Whisman (MEW) EPA Superfund site in Mountain View, California. Applied was awarded the contract after an exhaustive technology search and subsequent onsite testing that indicated Applied's HiPOx™ treatment system would provide the most effective and economical solution for removing contaminants such as 1,4-dioxane, trichloroethylene (TCE), 1,2 dichloroethylene, (1,2 DCE) and vinyl chloride. Applied delivered the treatment system, designed to site-specific conditions, at the end of November. The system is now going through final commissioning and will be fully operational shortly.

Terry Applebury, President and CEO of Applied, stated, "We are very pleased to be recognized for the superior treatment efficacy and fail-safe operation delivered by our HiPOx technology. This technology has been proven time and again in field tests and at commercial installations to destroy 1,4-dioxane and a host of other contaminants. We are certain that it will meet the client's expectations at this site."

The HiPOx advanced oxidation technology mixes hydrogen peroxide and ozone to form hydroxyl radicals, an aggressive oxidant that reacts chemically with volatile organic compounds (VOC's) including 1,4-dioxane, vinyl chloride, TCE, PCE, MTBE, TBA and other compounds, converting them into benign carbon dioxide and water. The carbon dioxide is vented off, while the cleansed water is returned to the ground or put to productive use. Unlike air stripping and carbon systems, HiPOx actually destroys contaminants onsite rather than transferring them to another medium for further treatment and disposal.

The HiPOx system at the MEW site is designed to treat up to 50 gallons-per-minute (gpm) of groundwater. A compact HiPOx "cabinet unit" with a footprint that measures approximately 8 feet by 4 feet is being installed.

Applied Process Technology, Inc. provides technically superior pump-and-treat and in-situ water treatment solutions and services to the drinking water and environmental remediation markets. Applied specializes in treatment technologies that do not generate by-products or waste streams. Its first two product lines, HiPOx™ and VadoZone, are based on advanced oxidation processes that destroy a wide variety of contaminants including MTBE, TBA, VOC's and 1,4-dioxane. Additionally, Applied and its alliance partners offer other technologies that treat a variety of contaminants including perchlorate. New, advanced products are under development.
