I haven't seen evidence of mold anywhere else in the property.I would like to fix this myself and avoid using remediation people if at all possible.1) Is the best course of action just to cut out those parts of the drywall/board that have it, so I don't risk contaminating other areas, rather than trying to scrub it off?

Most developers will look at the remediation work that is needed, which happens when the soil has been contaminated.

But the most outrageous is the apartment is contaminated with fleas and bedbugs from floor to cieling.Having cancer is one thing being filthy pigs is athother.

What I did not tell you , the loan term is amortized over 2 years, the park is only worth 450k and best part is since you were too hung up on a down payment, you did not dish out for a phase 1 and bought a contaminated property.  

A pawn shop takes all kinds of TVs, electronics and small appliances that, if damaged and left to sit can pose contamination issues.

To me 24 feet seems shallow but I would just insure the water is not subject to contamination from other sources (not to close to septic etc) and has adequate flow.

We have eliminated all oil due to the risk of contamination from leaks/spills and the additional insurance risks.If you have oil make sure you have spill coverage as it can cost hundreds of thousands to mitigate.

If you find a contaminated property you are looking to redevelop, you may want to look into the"Brownfields" Program.  

Because you want to remove the contaminated air from the house.

This category of liquid used to be called grey water, and is described as having a level of contaminates that may cause illness or discomfort if ingested.
