i'm taking a civil environmental engineering class at college and I got to thinking about hazmat cleanup. Particularly digging out the soil around a leaking oil tank. I see this as a growing market. Would a mini x be able to hand that type of stuff or would i need a full backhoe, or excavator. I don't own anything but in a couple yoears i'd like to have bobcat/mini-x combo with a dump 1ton. and i'm trying to figure out steady work i could get with the two. Also what kind of money do you get for that work, all I think i'd want to do is dig up the contaminated soil and haul it. What kind of certifications do you need (hazmat CDL comes to mind). I know the work is expensive to have done, but is that mostly disposal fees or do you get a premium for digging the dirt out?
