Hazardous waste buried on property under bank ownership

[Jeffrey Lacombe]

I have purchased a property from US Bank that while they owned it, they hired crews to remove of trash and debris.  One thing this crew did was bring in a backhoe, dig a large hole and put 55 gallon drums of car oil, transmissions and engines into the hole and covered.  There is a video of them doing this and eye witness.

What is my action of recourse?  I assume sue them for cost of clean up but could I also get additional funds from them?  Do you think it would go to court or would they try to settle out of court?

Concerned about fighting a large bank, but, I think I have a very good case!
