NORTH SHORE WATER COMMISSION'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 NORTH SHORE WATER COMMISSION's customers' taps is household plumbing, invisible to a system-level record ranked 8,033th of 12,903 by violation count.
