Americans’ knowledge of how to save water isn't exactly spot-on. A national survey found that approximately 75% of people believe curtailment actions, such as reducing shower lengths and shutting off the water while brushing your teeth, are the most effective way their household can save water—but that's not true.

Researchers who conducted the study—published online today in the Proceedings of the National Academy of Sciences—believe efforts to correct the public's misinterpretations need to be put in place.
