What this data is and is not
Everything on this page is WAUKEGAN's own reported record under the Safe Drinking Water Act - a regulatory filing, not a sample of your tap. This record - 5 health-based violations on file for WAUKEGAN - 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.
