I'm not a schill. I posted this thread. This sounds like a better idea than dredging.
Been there, done that, doesn't work.
I like the idea of bio remediation. Spray the oil slick owith bacteria, or introduce the bacteria in the contaminated sediment, let them chow down, recycle the bacteria in the food chain.
Since we know about the law of unintended consequences, I wonder about the types of by products these bacteria produce? I also wonder what happens when you spray them on blacktop. Do they digest the asphalt that holds the blacktop together?
You don't appear to understand. According to the article mercury is a driver for the remediation. Bioremediation is targeted at organic contamination, not inorganic contaminants such as mercury. Furthermore, sediment is anaerobic, and petroleum hydrocarbon degradation such as that in the advertisement you've posted is an aerobic process. The two are incompatible.
Bioremediation does work, and quite effectively in some cases, but it is not a cure-all and it needs to be carefully tailored to the situation at hand.
