Water sterilization study in the Philippines

IT WAS ENVISIONED THAT THE METHOD OF TREATMENT THAT WOULD BE RECOMMENDED WOULD BE FORMULATED IN A FORM THAT COULD BE INSTITUTED IN RURAL AREAS, UTILIZING MATERIALS AVAILABLE IN EVERY HOUSEHOLD AND THAT, MOST IMPORTANTLY, INSTRUCTIONS WOULD BE PRESENTED IN THE MOST SIMPLE TERMS THAT EVEN AN UNLETTERED INDIVIDUAL WOULD BE ABLE TO CARRY OUT AND THUS BE ASSURED OF SAFE DRINKING WATER. THIS STUDY EXAMINED SODIUM HYPOCHLORITE AND CALCIUM HYPOCHLORITE WHICH WERE FOUND TO BE EQUALLY EFFECTIVE AS CHLORINATING AGENTS USED TO DISINFECT UNTREATED WATER. THESE TWO AGENTS COST LITTLE AND ARE FOUND TO BE WIDELY AVAILABLE EVEN IN RURAL AREAS OF THE PHILIPPINES. THEY ARE EASY TO USE. THE SAMPLING METHOD AND DISINFECTION PROCEDURES FOLLOWED IN THE STUDY ARE DESCRIBED.
