I only posted so people realize that not in every state you can do this. We also have wells and you have to have laws so you don't contaminate your neighbors well.
I have a friend who has a farm in Missouri and I am sure they can do what they want, since they have hundreds of acres.
To throw politics in your answer was not very mature. We are also talking about keeping people safe.
It is the same with testing well water, since we have a lot
of ledge you can have radon in your water and certain area's have high arsenic. So when people buy a house the water get tested.
Yes a failed septic system should be fixed to prevent contaminating the ground water but it is also important that
you keep your neighbors in mind.
