I live in a rural area in central Illinois. My domestic water is supplied from a 22' hand dug, brick lined well. Through last summer's drought I never ran out of water. However, I have had the water tested by the state lab and we have microrganisms, nitrates from fertilizer and hard water. What I am looking for is some guidance on what kind of whole house filter, water softener, UV treatment unit and RO filter to get. There are normally just 2 of us living in the house. I have looked online and at the big box stores but I am uncomfortable with the the quality in many cases. I am also a bit hesitant about ordering something this important from California with no local dealer. I believe I have the ability to install and maintain the system. I am just looking for some feedback from other's experiences.
