WINNECONNE WATERWORKS'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 WINNECONNE WATERWORKS's customers' taps is household plumbing, invisible to a system-level record ranked 1,086th of 12,903 by violation count.
