Water Taste Test Winner

The City of Sumas has the best tasting water in Washington! ERWoW had our Water Taste Test on August 29 at the Fall Conference at the Great Wolf Lodge. We had 23 entries. Our judges were Nina Helpling with Department of Health. Glen Womack with NRWA and Kari Fenton with ERWoW. The samples were graded on taste, order and clarity. The City of Sumas will be going back to Washington DC in February to compete in the Great American Water Taste Test! Congratulations!
