(tl;dr at the end)Long,boring, poorly written story (read if you want):Living below my means has been a value that has been instilled in me from a young age, and in practicing this I've aggressively done what any money conscious college graduate with a job should do: pay off my student loans, and contribute to my Roth IRA.

Most generally, you'd want to drill holes in and around the tank, have the soil inspected by an ecological/hazardous waste company then determine if there's any contaminates in the soil.

Going forward,  if you choose to leave hundreds on the table because you like a tenant, consciously choose to do so,  knowing you might get smoked.  

It may cost you more money than you were planning to spend, but trust me, it's worth it.I hope this helpsP.S. please excuse any misspellings during my stream of consciousness.....
