Why "no violations" needs a caveat here

ALAMEDA WSD serves 2,480 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 ALAMEDA WSD 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. Water quality can still change between the meter and the faucet - household plumbing sits outside what a record of 0 logged violations can see. The guide to what this data misses covers that gap.
