John, Your statement; <<All soil naturally carries the "bugs", most insitu bio-remediation systems just enhance the bugs and provide a means to increase / excellerate their growth.>> Dr. Mery C. Robinson a.k.a. (the Bug Lady) and President of the Sub-Surface Waste Managenment Division of Global Venture Funding had this to say about that very topic; Biostimulation vs. Bioaugmentation/Soil Stabilzation, and Site Restoration. "Over the years, it has become a popular belief that the microbes that do the cleanup of contaminated sites occur in all or most sites and only require some sort of stimulation to kick them into gear and make them clean up the contaminated soils or other wastestream. While it is true that many sites do contain some levels of the "right" microbes, usually, they are not present in sufficient numbers to do the job. When the site is stimulated with fertilizers and other nutrients (e.g. Biostimulation-for example with the Valdez cleanup), there are other microbes which also also thrive on the nutrient stream which are of little use to the cleanup effort and which tend to discourage the growth of the truly beneficial and hard-working microbes needed to get the job done. When the site is seeded and treated with a sufficient number of microbes which have been selected and blended to address a site-specific contaminant and introduced to the site and allowed to do their job (e.g.Bioaugmentation as in the Queen Mary bunker oil cleanup, the landmark Cat Canyon/Santa Barbara County, Ca. cleanups and other agricultural wastestream cleanips, et. al.) the site is remediated or restored in a more efficient and cost effective manner." It is my understanding that the right synergistic mix of microbes is of the utmost importance. That is where the above individual is in her realm. Her work follows her fathers who devoted his attention on obtaining the proper mix of the microbes necessary to attack and remediate a specific waste site. That is where the Bug Lady is supposed to have the 30+ years of expertise. There is an article that appears in Civil Engineering Magazines September '97 issue that details the entire sequence and logistics. Many individuals who discredit bioaugmentation may not be aware that the right blend of microbes is mandatory. The system has been shown to be effective if the proper preliminary due diligence and subsequent proper ratios of microbes are applied. Sounds totally reasonable to me. Let's see if her expertise and ratio mixtures can undergo the scrutiny of other microbial-biologist specialist that will be making the determination to use Sub Surface Waste Managements- bioaugmentation in specific clean-up projects.
