What I will attempt to explain about private well water systems is not from a regulatory, global belief, or a theoretical perspective. It is from credible facts, personal observations, and discoveries that I was fortunate to be a part of. What follows, I feel, is a logical, systematic interpretation of a private well system from the raw groundwater source to the end user having a glass of water. Within these pages, my primary focus will be on the concepts with as much detail as necessary to explain them because I believe that stepping back and looking at the big picture results in more understanding than being inundated with too much fine detail.
