You're speaking from what I'll call a water and waste treatment engineering perspective, of using some type...? No. I have done some work where there have been some companies or organizations that have tried to treat some of this material with, say, advanced oxidation or something like that, and I've looked at how that has changed the toxicity of the material. But in terms of the actual engineering activity associated with changing the process of treatment, I'm not an engineer. I don't do that type of work; I look at the effect.
