A former chemical storage operation with historical groundwater contamination.

I have used chemical treatments on various units 3 times in the last 3.5 years.  2 of the units I am virtually certain was maid cross contamination (both units in detached duplex got bedbugs at same time with no common guests).The chemical pesticide amount used for bed bugs should be substantially higher than for termites.  

This will rarely change, but you need to tell AI how to think like you by telling it what you would be looking for when reviewing your data. b) a data injection prompt (uploading your report exports from Stessa/RentRedi) c) comparison prompt (feed prior year outputs into the model for YOY analysis.Each section that you listed should have its own prompt template so that results stay clear, errors don't contaminate the project, you can improve each module independently and rerun only the sections that you care about.

I engaged an environmental engineer for a preliminary report, and found the contamination much more limited than feared.  

I also have a large former refinery property that is in a sub S that I cannot ever put in my name due to contamination issues. 

The soil which we can assume is contaminated and be covered with mulch, straw (would pass a clearance test) or planting new sod. 

My two cents are the following:  you would want to check with the local jurisdiction's planning department to make sure they are okay with that type of use...even if the zoning technically allows it, sometimes, from an environmental perspective, they have concerns about oil and other contaminants seeping into the ground.

They may have requirements on the frequency of testing the water for contamination.

I did have some general knowledge of soil contamination and remediation, and figured $50,000 would clean up the problem.  

Whichever you choose, define pickup day, container location, contamination rules, and fines for overflow.
