Geweke, FRP - 4 - 15 September 1993 <br /> 1.8. There is no mention of how putting the liquid medium into wells will affect ground water <br /> (LI flew or contamination. <br /> There was no estimate of how long in-situ bioremediation would take at this site. <br /> The following information must be submitted: <br /> 1. Locations and descriptions of GL-3, GL-4, and VW-1 through VW-4; <br /> 2. A signed copy of the letter in Appendix C; <br /> 3. A proposal to remediate the "smear zone"; <br /> 4. Data on any laboratory studies, bench scale tests, and feasibility studies already conducted; <br /> 5. Soil characteristics such as pH, FC, moisture content/water-bearing capacity/moisture <br /> retention curves, adsorptionidesorption gates, metals toxicity, oxygen demand, nitrogen <br /> content, phosphorus content, trace mineral content, porosity, and soil particle size <br /> distribution; <br /> 6. Discussion of how the existing soil characteristics will affect in-situ bioremediation and how <br /> they may be modified or controlled to improve remediation; <br /> 7. Number and location of wells to used to introduce bacterltotthe ground water; <br /> S. Contents of the medium and bacteria] species in the consortia; <br /> 9. Volume of medium plus bacteria to be placed down each well and total volume to be used in <br /> each inoculation; <br /> 10. Whether more than one inoculation will be necessary; <br /> 11. Whether nitrogen, phosphorus, and any other nutrients must he added, and the method and <br /> location of introduction; <br /> 12. A monitoring program to monitor soil moisture, ground water elevation during soil <br /> bioremediation, if nitrogen must be added, the presence of nitrate in the ground water; <br /> SO' d 800' ON ££:6 25, 91 dad ON 131 <br />
