A safe water supply source should be obtained from an uncontaminated water-bearing formation or from a properly located and constructed farm pond. The water should be pleasing to drink, bacteriologically and chemically safe, and delivered through a system which will keep it safe at all times. To accomplish this, the water source and system must be located and constructed to keep out surface and near-surface contamination, or be continuously treated.
