Reasons for Monitoring

• Protection of the Environment
  • Fugitive gas emissions
  • Leachate seeps
  • Liner leakage
  • Slope failures
    
    
• Gauging System Benefits
  • Waste stabilization
  • Gas generation rate and quality
  • Leachate quality
  • Settlement rate
    
    
• Improving System Performance
  • Compare wetting and gas collection methods
  • Assess leachate treatment options
  • Experiment with cover materials for control of gas emissions
  • Operate anaerobic and hybrid to compare the rate of stabilization
  • Monitor cold weather operation

Proposed Monitoring for the Buncombe County Bioreactor

• Leachate Quality and Quantity
  • Monthly monitoring (until stable)
  • Test for pH, BOD, COD, and Ammonia
  • Monitors leachate treatment and decomposition process
  • Ongoing for wetting process and leachate removal
  • Flow meters at each pump station
  • Needed to obtain optimum moisture content and avoid oversaturation
    
    lllllllll
    
    
• Gas Composition, Volume, and Flow Rate
  • Quarterly surface sweeps
  • Ongoing volume monitoring
  • Monthly flow monitoring and composition at the wellheads
  • Determine impact of bioreactor on gas production
    
    
    

• Liner System Leakage
• Monthly samping and testing
• Determine performance of alternative liner system
  
  
• Waste Stabilization
  • North Carolina State University – Dr. Barlaz
  • Buried waste vessels
  • Test for BMP and moisture content
    
    
    
    
• Settlement
  • Quarterly survey of plates and annual aerial topographic survey
  • Monitor rate of settlement and airspace gained
