Water from Wells
There are a number of wells in use, the majority of which, however, supply
water used only for industrial purposes. The water from two wells is used for
drinking purposes, or for the preparation of food. Reports of the analyses of
water from these wells are received regularly and have been satisfactory for the
year under review.
