What this data is and is not
Oak Park Heights'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 5 logged violations can see. The guide to what this data misses covers that gap.
