 On well water, like I said, if there is chances of arsenic or things like that, I do recommend a state lab. There is one in Detroit Lakes that does a great job at that. It's all a state report and a lot of times I will go get the test and I will bring it to the lab and then they email me and then I can break down and tell you what's in your water, how we can fix it, what's the next step. How many different systems are there?
