part of the county the artesian water is already tQo highly mineralized to be suitable for irrigation or for domestic or public water supplies. These areas of high mineralization should be definitely outlined, and the adjacent districts should be carefully studied to determine whether the highly mineralized water is encroaching on the areas of low mineralization. If encroachmept caused by draft frommwells is taking place, methods can be adopted for preventing or retarding the process. A careful study of the pressure heads or water levels in wells throughout the county will give much needed information regarding the fluctuation of water levels, the extent of the permanent loss of head that is taking place, the direction of flow of the artesian water, and the effect of withdrawals of water on the mineralization.
