It appears to be an old 1 1/2" copper pipe. It is not Cast Iron because it does not bend.

I doubt it is copper, it is 1/4" thick, even type K copper is not this thick.
As I dug down deeper and deeper, the soil I excavated became more and more reddish orange, this is consistent with cast iron pipe corrosive color, never seen copper pipe do that.
The bent can possibly be explained by the backhoe hitting it. That's a lot of force, or years ago something rolled over it when compacting the crushed stone base for the asphalt driveway.
But my main concern is whether it is broken off of something it's connected to, can a septic tank be 42" below? Do septic tanks have vents?

Cast iron would break before it bent. The top end appears to have been driven in with a sledge hammer. Probably a piece of 1 1/2" galvanized pipe used as a guy wire anchor for a TV tower or a clothesline post.

Nice fence. are you going to stain it? clear?
your water table is ridiculously high. You are lucky there are no earthquakes in Florida - just the hurricanes and alligators.

Sum, did you ever determine what that rectangular underground chamber was?

Here is a picture with the dirt I dug up next to this pipe.
I don't think copper will stain the dirt like that. This is from something ferrous.

I never did find out what that rectangular thing was. I end up measuring it's size and location then filled it in entirely.
Some thought it may have been a cistern, some thought it may have been a gray water dry well for a washing machine, some thought it may have been a home made rectangular riser with a septic tank below.
