What this data is and is not
Everything on this page is CARLSBAD MUNICIPAL WATER SYSTEM's own reported record under the Safe Drinking Water Act - a regulatory filing, not a sample of your tap. Water quality can still change between the meter and the faucet - household plumbing sits outside what a record of 21 logged violations can see. The guide to what this data misses covers that gap.
