Kohler: The grcater Anchorage Area Borough Department of Environmental Quality has received a satisfactory chemical water analysis on the subject water system. The chemical analysis was completed by Alaska )ltneral and ~aterial Laboratory on August 12, 1974. It is interesting to note, when reviewing this chemical analysis, that your water supply has one-half part per millionth fluoride in the supply. For your information this can be of a substantial benefit to young children during the ages of one (1) through ten (1el years old in the prevention of dental cavities.
