Bragging rights and a trip to the national water tasting championships are at stake as water utilities square off at Maine’s 26th annual drinking water taste test competition. The Maine Rural Water Association is holding the taste tests Thursday at its yearly conference and trade show in Freeport. For the testing, water districts compete in chlorinated and non-chlorinated categories. The winners in each category then compete in a “taste-off” to determine the winner, which represents the state in the National Rural Water Association’s Great American Water Taste Test in Washington, D.C., in February. The Kingfield Water District was the winner in last year’s contest in Maine.
