I live on a small inland lake in Michigan. We've not had our well tested in years. We have rust stains and most recently it smells like sulfur when running the hot water. We are having our hot water heater looked at and thinking about a filtration system.

I think it would be beneficial to get the well tested but am overwhelmed by all the tests offered by our county and the State of Michigan. It could be really expensive to test for all the contaminants. I am looking for recommendations on what tests I should have done on my well water.
