For over a decade, the National Rural Water Association (NRWA) has ranked tap waters from around the country. Its Great American Taste Test awards the top three for their overall taste, clarity and bouquet. “Judges tell me that the best-tasting water tastes ‘pure,'” says water analyst Mike Keegan, of the Oklahoma-based NRWA. Other descriptors include “refreshing,” “satisfying” and “tasty.” Typical winners are also often characterized as “tasting good versus tasteless,” he adds.
