摘要
Processes for removing hydrocarbon contaminants from soil and groundwater via enhanced biological denitrification. A contamination zone of groundwater and/or soil is identified to define a volume or zone of contaminants to be treated. A source of nitrate is applied to the contaminant zone to serve as an electronic acceptor for enhanced bioremediation of the petroleum hydrocarbons. A further carbon source, secondary to the primary contaminant hydrocarbons, is added to form a barrier about the nitrate treatment zone to stimulate degradation of any nitrate migrating from the treatment zone. A further carbon source is also added to stimulate the degradation of any residual nitrate once the primary carbon source of the contaminant hydrocarbons have been destroyed.
