Methane Soil-Gas Testing
|
|
Methane is a combustible natural gas which can accumulate in soils at former or active oil fields, dairy farms, and landfills. Due to its explosive nature, high concentrations and/or pressures of methane gas, accumulated underneath building structures, can create unsafe conditions. In order to prevent potential fire/explosions, the City of Los Angeles and many surrounding cities/counties, have mapped specific geographic areas as being within a Methane Zone or Methane Buffer Zone. When a new building is proposed for construction, or when certain additions are to be made to existing buildings within these Zones, the B & S Departments require that the sub-surface soils be investigated for methane and other soil gases.
