Hand-washing improves quality of stored water (ANI) – Alexandria Boehm, Jenna Davis, and their students note that almost half of the world’s population — over 3 billion people — have no access to municipal drinking water supply systems. They obtain drinking water wells, springs, and other sources, and store it in jugs and other containers in their homes. Past research showed that this stored water can have higher levels of bacterial contamination than its source.
The scientists found a strong link between fecal contamination on the hands of household residents and bacterial contamination in stored water in Dar es Salaam, Tanzania.
Stored water contained nearly 100 times more fecal bacteria than the source where it was collected.
