Central Iowans should feel safe drinking tap water. That’s the message behind a new information campaign, Water for All, which seeks to give immigrants and refugees reliable and science-based information about tap water in Polk County. The campaign, a joint $150,000 project between Polk County, Des Moines Water Works and the University of Iowa, is based on a study that found low-income and refugee residents are more likely to drink and spend money on bottled water instead of tap water.
