Yeah , that's what I'm thinking too, Phil.
Your county health department could probably have it checked for you. If not try your agricultural agent. If they can't help, try the state agencies. For your own sake, and your family's, you need to know what's in your water. Just because the water came out of the ground does not make it safe. Some wells have high concentrations of
atrazine and other ag agents. Some also have heavy metal problems, mine run off problems, etc.
