I didn't see any question in your post.
The statement that the water can't be treated is incorrect.
I really don't see anything wrong with what was done or how it was done. And I know that unless you had a few acres to drill on and were willing to have the well so far from the house, probably any location on say a 1 acre lot would result in the same situation. Maybe anywhere on 10 acres since the neighborhood has a problem with dry wells.
How did it come about that you bought a house in such an area?
IMO the BBB is a sham.
Is there someone that you think did wrong or something you believe was done wrong?
