Why "no violations" needs a caveat here

CASS CO RWD 1 serves 2,958 people. EPA requires smaller systems to test less often than large ones, so a clean record here is real but weaker evidence than the same record on a system serving hundreds of thousands - fewer tests means fewer chances to catch a problem. See the guide to reading a clean record for what that does and does not tell you.

What this data is and is not

This is what CASS CO RWD 1 reported to its state primacy agency and EPA under the Safe Drinking Water Act - real regulatory record, not a lab test of your specific tap. This record - 0 health-based violations on file for CASS CO RWD 1 - 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.
