Why some towns say “no public system”. A handful of towns here are served almost entirely by private wells. Nobody is required to test a private well — not at purchase, not ever — so there is no public record to publish. Those pages say so plainly rather than showing a neighbouring town’s numbers.

What these reports are not. Every figure comes from a sample taken at a wellhead or out in the mains, never inside a house. Your own service line, solder and fixtures are the last thing the water touches, and no public report covers them.
