There was talk on the news of a 30M solution. I can't imagine a wall. Would that be terracing the whole mountain?
I don't think there's a shortage of research in this country. I can't imagine Japan or any other country even coming close to the amount of research done at our universities and all the different firms and groups out there. For just about every aspect of our society--medical, social, science...
You may get better success if you know what your dealing with. Depending on the contamination and the site specifics, the microorganisms can be very different. There are labs that can profile your biomass. Once you know what you've got you may be able to target the bad actors.
