| 摘要 |
The invention provides repeated sequential stages of chemical and biological treatment to meet soil and/or groundwater treatment goals. Chemical treatmen t is undertaken to directly destroy a portion of the contaminants via oxidatio n, with such chemical treatment occurring in discrete injection events. Near th e completion of an injection event, the remedial additive concentrations or delivery rates are increased. During or subsequent to the chemical treatment event, beneficial nutrients and additional microbial populations are added t o the soil and or groundwater based upon field or laboratory testing and calculated optimal concentrations.
