Many Americans are confused about the best ways to conserve water and have a slippery grasp on how much water different activities use, according to a national online survey conducted by Indiana University Assistant Professor, Shahzeen Attari.
Experts say the best strategy for conserving water is to focus on efficiency improvements such as replacing toilets and retrofitting washing machines. However, the largest group of the participants, nearly 43 percent, cited taking shorter showers, which does save water but may not be the most effective action. Very few participants cited replacing toilets or flushing less, even though toilets use the most volume of water daily.
