What Cascade Municipal Water Supply's record does not cover
Everything on this page is Cascade Municipal Water Supply'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 13 logged violations can see. The guide to what this data misses covers that gap.
