What this data is and is not
ST MARIES CITY OF's numbers here come from its own required reporting to EPA under the Safe Drinking Water Act, not from an independent test of your glass of water. Water quality can still change between the meter and the faucet - household plumbing sits outside what a record of 25 logged violations can see. The guide to what this data misses covers that gap.
