2.) Ultraviolet light/hydrogen peroxide oxidation is another'technology we have used to remove TCE and its breakdown components from groundwater. A thorough discussion of this process attached, from Dr. W. Carey of Nestle Foods about Rayox System (See Appendix). 3.) In-situ bioremediation is another technology we have used to remove TCE from groundwater. A trial run at our factory, where the TCE readings were much higher than the Stockton Street property, showed sizeable drops in relatively short time period and the readings stayed low even months after all treatment was stopped. The work to date has been done by ECOVA Corporation with technology developed by government utilizing certain bacteria strains to feed on toxics like TCE and break it down to harmless forms. The bacteria strain is rather common and does exist in our soil and water samples naturally but not in large enough quantities to reduce TCE levels. ECOVA will take samples of water from the site and encourage the development of this bacteria in the laboratory. Then they will bring the culture to the site and inject. Drawing #4 shows a schematic of equipment used in pilot trial. We would propose a similar layout for Stockton Street cleanup. Figure #2 shows the results of our Industrial Ave. work with bioremediation. The real plus for bioremediation, besides being quick and effective, is that it does not require wasting any water. The negative is the fact that we don't know yet how mobile it will be. In other words, how many injection wells will we have to drill to reach all the contami- nation. In summary, applying the three technologies described in this proposal are the best alternatives that we see to stop the spread of groundwater contami- nation. We have been working with the State of California Regional Water Quality Control Board since discovering this contamination in 1986. They are reviewing each step of our study and cleanup efforts. As I said, before we have used all of these technologies on our factory site at 230 Industrial Ave. , with good results. The Stockton Street site has the highest readings of contamination found in the study, next to the readings we had at factory site. Now the Stockton Street location has the highest TCE readings. The State has recently emphasized that the Stockton Street contamination should be cleaned up soon. We have rented the property to give us access to do the cleanup in an expedient manner. If you have any further questions about these cleanup technologies or about our plans to apply them, please contact us prior to the permit hearing. We would like to have the answers for your questions in an effort to get approval in one appearance.
