What CREVE COEUR's record does not cover
Everything on this page is CREVE COEUR's own reported record under the Safe Drinking Water Act - a regulatory filing, not a sample of your tap. This record - 4 health-based violations on file for CREVE COEUR - 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.
