I think the letter is a CYA to show the state that they asked for the info, I am not understanding the well pump issue. I would think a person has a separate shallow well to water the lawn that has no connection to city water,or a resident is totally on a deep well because they have no access to city water.... So that part is confusing to me. I dont know why a well would be physically piped into a city water.... Good to hear from you Op, You are in pur prayers!
