Reference: Lisa Alvarez-Cohen, Civil and Environmental Engineering University of California, Berkeley, Earth Science Division, LBNL www.EOSRemediation.com Copyright © 2011 EOS Remediation, LLC Slide 6 Applying In Situ Bioremediation Natural Attenuation – biotransformation occurs naturally: indigenous microbes present, substrates & nutrients present (can be Monitored Natural Attenuation MNA). Biostimulation / bioenhancement - indigenous microbes present, but substrates &/or nutrients must be added to foster bioactivity. Bioaugmentation – indigenous microbes not present, so organisms are added. www.EOSRemediation.com Copyright © 2011 EOS Remediation, LLC Slide 7 Why Bioremediation?
