What this data is and is not
QUARRYVILLE BORO'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. Between the utility's meter and QUARRYVILLE BORO's customers' taps is household plumbing, invisible to a system-level record ranked 1,550th of 12,903 by violation count.
