Before posting this , I did a search for "oil tanks" in this group.
I got 84 results that ended up getting OFF TOPIC.

I saw some stupid advice, about "playing stupid" or "claiming
ignorance" of the EXISTENCE of an underground tank. I thougth I could
get away with this.

That no longer works.

Here in NJ, my next door neighbor is selling his house.
He had ( for whatever reason ) NOT ONE BUT TWO tank detection companies
come down and wave their magic wands looking for a tank.
The act of "playing dumb" about the existence of a tank won't work
here.

My neighbor and I got into a discussion about locating our tanks.
I plan on having a company come in and check and sand or remove it and
hope for no MAJOR $$$$ problems with contaminated soil.

My neighbor ended up sucking out sludge and sanding his tank HIMSELF.
He has NO paperwork and NO inspection was done when he cut the top
open.
Half his tank is under an extension on the house and the other half is
in the yard.

He tells me it is about 4 FEET to the top of the tank.
My tank then is about 4 FEET deep and under a 4 inch patio slab - more
work and $$ to remove and replace the patio in order to work on the
tank.

The MAGIC WAND that the tank detector companies use
How deep can they detect a tank ???
Do they detect straight down or can they detect tanks on an angle such
as under edge of a foundation ???
I say concrete is NO barrier to them. My neighbor thinks they may NOT
detect my tank. I disagree.

I found no posts on any of the above.
