Padre is currently assisting a San Francisco Bay Area school district with the bioremediation using land-farming techniques of approximately 4-acres of PCBs-containing soil as part of the development of a new elementary school. Padre’s Sacramento school site consulting / development team led by Alan Klein, C.E.M. and Alan Churchill, P.G. is managing the project. The photo below shows the mechanical tilling of the PCBs-containing soil following the application of the bioremediation active agent and moisture conditioning. The bioremediation process is estimated to require approximately 90 days to complete.
