Water Our Thirsty World held its third annual Water Walk in Mt. Pleasant on Thursday night. Participants walked one mile while carrying two gallons of water — about 16 pounds — to represent the hardship that many in the world face when they are required to walk long distances each day to search for water. Funds raised from the walk will help distribute chlorination devices and dig wells in parts of the world that do not have safe drinking water. There were also walks held in Mediapolis and Urbandale.
