Develop Remediation Action Plan and Addenda (Rule 62-770.700, F.A.C.), which included excavation and on-site thermal treatment of over 60,000 cubic yards of soil, groundwater pump-and-treat, air sparging, and soil vapor extraction. Operate, maintain, and troubleshoot remediation systems. Negotiations with Orange County's environmental personnel minimized the volume of excavated soil while maintaining high environmental standards. On-site soil treatment substantially reduced costs versus off-site methods. Innovative use of horizontal drilling methods minimized site disruption and repairs to newly-installed pavements.

Agricultural Methane Consulting - Granja Jeroa

Location:	Mato Grosso do Sul, Brazil
Client:	Estância Jeroá Suinocultura Ltda
Need:	Design, construct, operate, and monitor an 8,800 M3 anaerobic digester system that optimizes retention time and maximizes CH4 capture.
Scope:	Develop and implement practice changes in animal waste management system from open lagoons to an anaerobic digester system. Design, construct, operate, and monitor an anaerobic digester system. Develop a Clean Design Mechanism (CDM) project for sale of Certified Emissions Reductions (CERs). Design and construct carbon-neutral source of renewable energy to supply constant biogas to an 80 KW generator. Provide a renewable free source of energy from farm waste. Created new revenue stream for client from the sale of greenhouse gas emission reductions. Client reduced electric bill by generating power using biogas (free source of energy). Reduced greenhouse gas emissions on livestock farm. Reduced odor and fly population, benefitting both client and surrounding neighborhoods. Improved waste-effluent fertilizer quality. Prevented groundwater and surface water contamination. Allowed client to increase production capacity without violating environmental regulations. Reduced client's effluent discharge BOD and COD levels. Helped client meet environmental laws and regulations.

Agricultural Methane Consulting - Granja Santa Irene

Location:	Cachapoal Province, Chile
Client:	Agricola Santa Lucia Ltd
Need:	Design, construct, operate, and monitor a 12,190 M3 anaerobic digester system that optimizes retention time and maximizes CH4 capture.
Scope:	Develop and implement practice changes in animal waste management system from solid separators and open lagoons to an anaerobic digester system. Design, construct, operate, and monitor an anaerobic digester system. Design and construct carbon-neutral source of renewable energy to supply constant biogas to a 650,000 Kcal/hr boiler. Provide a renewable free source of energy from farm waste. Client can generate hot water with renewable energy (biogas). Client can modify diesel boiler to use biogas and eliminate monthly diesel fuel consumption (operational cost reduction). Reduced greenhouse gas emissions on livestock farm. Reduced odor and fly population, benefitting both client and surrounding neighborhoods. Improved waste-effluent fertilizer quality. Prevented groundwater and surface water contamination. Allowed client to increase production capacity without violating environmental regulations. Reduced client’s effluent discharge BOD and COD levels. Helped client meet environmental laws and regulations.
