I was a military wife for 6 years, before my husband was honorably discharged.  

The guy is in the Air Force and is pending a medical discharge.

We have a bankruptcy 4 years discharged, we are building our credit (him at a 650 and me at a 620) but only as of recently.

#1 - I do not see accidental water discharge listed- although it could still be included.

Maybe there was an accidental/negligent discharge from the inside.

Septic could be problematic since oils and cleaning chemicals could be discharged and then leach into soils/groundwater.

waste fluids could have been discharged into septic system.(5) you say gas station is currently vacant. have the tanks been properly closed in accordance with temporary closure requirements? 

The owner received the notice of discharge, due to bankruptcy, from the lender in Feb 2019.Because I have the connection to the former owners, I know who the lender is and I know that the property is not currently being communicated to the public as a foreclosure.

They need to slope up until discharges from the building.
