This document discusses methods for simulating bacterial growth on brownfield sites to aid in revegetation efforts. It describes taking soil samples from various points on an industrial site and growing bacteria from those samples in a gelatin simulation over 30 days at 25 degrees Celsius. This small-scale simulation allows for an accelerated view of how bacteria and potential plant growth might occur on the brownfield, identifying remediation needs to support amendment and safe reuse of the land. The simulation provides time intervals for bacterial multiplication at different scales to optimize brownfield revegetation strategies.

- 2. Brownfield revegetation Why is it important? By amending brownfield sites we Make ground water safer Increase homeostasis create oxygen production form animal habitats
- 4. Soil formation 2 Since soil bacteria is susceptible to climate, time, and necessary for making nutrients accessible for plant growth we concentrate on them.
- 5. Industrial site in operation
- 6. Industrial site in operation 2 By knowing the points of operation at the site when in use one will know the points of highest concentraion of soil contaminantschemical analysis to confirm. Seeing the plant in operation you can identify the soil parent material.
- 7. Present state of site Brownfield
- 8. Present state of site Taking soil from five points first the four points shown in the picture the circumference or the upper level soil (parent soil) then the fifth point the lower flat level.
- 9. Brownfiled bacterial growth simulation Simulation
- 10. Brownfiled bacterial growth simulation method 112 grams of gelatin boile in 300 mL of water until gelatinized 1 gram of soil form five points of the present day site. Left in a 25 degree celsius environment for 30 days.
- 11. Measure twice plant once Using a smaller simulated culture of the brownfield allows for an accelerated propagation giving the growth pattern for bacteria,therefore, plant growth. The simulation will show the effects of the contaminations allowing for precise actions needded for amendment and remediation of the brownfield site.
- 12. Time interval per area
- 13. Time interval per area The graph shows the duration for bacteria that multiply from 1E5 to 1.9E18 ( amount of bacteria per acre) and 1E5 to 1.6E7 (amount of bacteria on surface area of 2 cm2). Giving an accelerated propogation.
- 14. Conclusion By using a small-scale brownfield simulation one can increase the efficacy of amendment reducing time, cost, and resources.
