Production Possibilities Curve to clean up the Petroleum contaminated The Y Axis of this Graph represents the money spent on Equipment, Chemicals and Energy required to clean up a given quantity of contaminated soil. OUTSIDE CAPITAL Greater Benefits Expanding out from Curves Q0 to QL show greater Benefits like the Amount of Soil Bio-Remediated for a specific combination of Money as Capital and Labor. The X axis represents money paid to workers in the form of wages and benefits to clean up a given unit of contaminated soil. WAGES and LOCAL EMPLOYMENT • BOBS SCHEME 7 Disadvantages of Conventional Remediation Methods • high chemical, mechanical and transportation costs • offsite and/or onsite pollution • not true remediation (burning, chemical, burying, relocating) 8 International Success of IOS-500 Bacteria on Petrol-Contaminated Soils • We will demonstrate several systems for growing and implementing non-toxic bacterial methods that are adequate for petroleum spills on land and in various aquatic environments. 9 Santa Alejandra Swamp 11 12 13 14 GROWING METHODS: Composting as Bacterial Farming • Utilizing bacteria in a composting process to treat waste products such as petroleum contaminated soil. 15 BP Cleanup Site in Egypt. 16 DILUTION! Bacteria and Carbon are the magic ingredients. It is necessary to dilute the concentration of contaminants below a level of 15% and provide Carbon mass to support bacterial survival and augmentation (Cow and Chicken manure are excellent supplements) 17 The Fire Triangle Analogy Critical components for the survival of aerobic Bacteria (like us we need food and oxygen to survive) 18 Why Bioremediation is an Art Composting microorganisms require the correct mix of carbon, nitrogen, oxygen and water to operate. The recipe: • • • • • Blending the correct ratios of raw materials during windrow formation is one of the key steps to successful composting. According to literature, the optimum recipe will have a carbon-to-nitrogen (C:N) ratio of between 20:1 and 30:1. This means there will be between 20–30 units of carbon, by mass, for every unit of nitrogen present. The optimum moisture content of the recipe is 40-60%. Feel is the best measure for determining proper moisture, because clay and sand hold different amounts of water and feel different in the hands. The materials must be blended or piled to allow for oxygen to infiltrate the pile — materials should not be compacted in a compost pile.

Short term, Long term planning. 43 Potential proposals • Present here today we have universities, indigenous, regional organization leaders, municipalities-- each with their individual strengths. • A Communication platform to elaborate on the social and environmental problems to work to find the adequate solutions • Ideally, an institution where we can collectively train local leaders, organizations, students, professors in these multi-disciplinary themes and investigations • Ideally, a location for on-site remediation demonstrations and continued training Criteria: security, electricity, containment, capacity, credibility, etc. (potential sites like Municipality of Cascales where criteria are met) • Such pilot projects can provide important opportunity to organize our collective strategies in preparation for the larger scale remediation that will be possible when the Texaco Case is successfully concluded. 44 A Proposed Example of Stacking Multiple Functions that hypothetically could provide jobs for Affected Communities, and improve the economy. • Grow Enormous numbers of Bacteria using waste products in the manner that Alvaro Borja is in process of demonstrating at the City of Cascales and then using these bacteria to treat the landfill leachate to reduce the strength of the pollution being discharged to rivers. • These same bacteria can then be used in many other applications including: Bio-Remediation of Petroleum contaminated soil, and in agriculture to treat fungal and bacterial plant pathogens including Black Pod which is attacking the Cacao Crops, and other agricultural commodities. 45 • WE APPRECIATE YOUR PRESENCE, YOUR ATTENTION, AND YOUR FUTURE COLLABORATION OF IDEAS AND PROJECTS. Robert Rawson, President of Bioremediation International [email protected] Alexis Gropper, [email protected] 46 Controlling temperature is important 47 Windrow pile construction. • 4 feet (1.25 meters) or more high, by as much as 12 feet (3.5 meters) across in layers of matrix such as manure or green chop and contaminated soil. I like a 9 foot high pile. • Consider Mass Effect in determining the size. More mass more heat and more moisture retention. Cold and warm climate are considerations. 48
