What CHATHAM WATER DEPARTMENT's record does not cover

This is what CHATHAM WATER DEPARTMENT 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 68 logged violations can see. The guide to what this data misses covers that gap.
