What Quechan Utility's record does not cover
Quechan Utility'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 490 logged violations can see. The guide to what this data misses covers that gap.
