OCT 23 89 14:44 BIO NP"TOh4AL CORP. <br /> BIO NATIONAL CORPORATION <br /> Water, drawn from below the floating product in the collection/bio-treat- <br /> ment tank, will be transferred to a 500 gallon surge tank to continue <br /> biodegradation as the water is drawn to the AOU and treated for final <br /> disposal. The AOU's ozone/uv/carbon procedure will destroy residual <br /> microbes and oxidize remaining contaminants. (NOTE. The system has the <br /> flexibility to utilize the AOU as a pre-treatment before biodegradation, <br /> but the amount of floating product precludes this as the <br /> most viable alternative at this time.) <br /> We will draw samples of extracted, bio-treated and ozonated extractions <br /> daily for one week, every other day for two weeks, and weekly <br /> thereafter, These will be submitted for laboratory analysis and reported <br /> to you as directed. On site air pollution control and water quality <br /> readings can be made available, as you require. We will maintain pH and <br /> Oxidation ]Reduction Potential (ORP) records as well. <br /> APPLICATION FOR VARIANCE TO TREAT CONTAMINATED SOILS IN SITU - As <br /> previously stated in numerous prior communications, we will submit, <br /> during the groundwater extraction phase, an application to DOHS/Alterna- <br /> tive Technology, for a variance to treat the contaminated soils in situ. <br /> We hope to initiate this phase of work while the groundwater extraction <br /> phase is still underway. The movement of groundwater toward the <br /> extraction well MW-'1 is important to the process for containing potential <br /> excess watery inoculum in biotreatment, or returning ozone charged -water <br /> in soil flushing, should that be a required component in the approved <br /> system. <br /> WE ARE R-8QUEST1NG NO ACTION ON THIS PHASE NOW. THE RESULTS OF <br /> THE PHASE II REPORT WILL BE THE BASIS OF A VARIANCE APPLICATION. <br /> Thanks for your prompt reply. The groundwater extraction equipment is <br /> ordered for two week delivery. We will have a set of Mass Spectrometer <br /> readings on the treated well development water available after a minor repair <br /> is effected on the AOU. <br /> Kindest regards, Y <br /> 0;el <br /> Gerald Todd, Ph.D. <br /> President <br /> cc: Dames & Moore/Duane Balch <br /> Holt Bros./Al Nielsen <br /> RWQCB/Tom Peltier <br /> DOHS/Aternative Techriology/Dr. Iden Smarkel <br /> 2 HOLT910 <br />
