Do I need to worry about this? Has anyone else received an email about account sharing?

I moved into my house last year. It's on three acres and has a septic system in the back. The grass on the septic mound is pretty consistently brown, so I assumed the weeping bed was located there.

This spring, I started digging a pond. But while digging tonight, I hit concrete about three feet down in the soil.

I specifically dug the pond far from the septic mound, assuming that the weeping bed wouldn't extend that far.

The house was built in the 90s. This land is zoned agricultural.

Any idea why there is concrete underground? Is this an old septic system? Is there any chance it is connected to the current system? Do I have to start digging a new pond somewhere else on the property (please god say no)?

I originally posted this in the septic tank subreddit, but no one seems to have an answer there so I thought I would see if anyone here had some suggestions.

Moved into my house last year. The septic system is directly behind the house and it is in a long mound that extends ~100 feet. I assumed that this was where the weeping bed was under the mound, as the grass in the back half tends to be brown.

I started digging a pond this month. I chose to put it past the aboveground pool, as I figured it was a safe distance from the septic system. Today, I hit cement roughly three feet underground. Would this be an old septic system? Is this somehow part of the weeping bed?

The house was built in the 90s so I guess it could be possible that it is on its second system?

In my field, muddy size 9 boot for scale.

I started digging a pond a couple of weeks ago with the intention of making something deep enough for leopard frogs to overwinter in (a few died in my shallow pond this winter, I did not expect them to try to shelter in 3 inches of water and am pretty upset that it happened).

I was following the advice someone had offered in this sub about taking it slow, shoveling for an hour every other day. And then it rained.

My questions at this point:

1. do I need a liner? I bought one but I'm starting to think there's more clay in the soil than I originally thought.

2. the deepest point of this pond is probably around 3 feet. If I can forego a liner, would I still need to dig to a 6 foot depth for leopard frogs to survive the winter or can they dig into the mud?

Also, I should note that the water wasn't that murky originally. I continued digging out what I could today, which is why it looks like a mud puddle.
