Only about a third of Americans say they usually drink straight from the tap. There are costs associated with mistrust of tap water. This report, which focuses on tap water mistrust in the city of Los Angeles, found that L.A. households purchasing bottled water pay 25 to 125 times the cost of tap water. This can add thousands of dollars to household expenses each year.
