I don't have any in a consulting capacity at the present time, nor have I had any in the last.... Actually, this whole exercise started 15 years ago with a three-day consulting job to look at the potential for the presence of some toxic chemicals. I said that, yes, there were some, and pointed out some issues. I thought this area might be something to research. Since that time 15 years ago, it's all gone through the university to support graduate education.
