What this data is and is not
Everything on this page is Saint Joseph's own reported record under the Safe Drinking Water Act - a regulatory filing, not a sample of your tap. This record - 1 health-based violation on file for Saint Joseph - stops at the meter and cannot see household plumbing on the other side of it. The guide to what this data misses covers that gap.
