answer:Well, in most municipalities in this country – and all of the ones that I’ve lived in since my childhood – municipal sewer systems are part of the infrastructure. And all homes are hooked up to them, and all homeowners pay. The billing is usually a combined “water and sewer” charge, with the sewer charge being the larger part of the bill. I’ve had a well, and I liked it, but they aren’t inexhaustible, they are still subject to introduction of pollution from various sources, including farm runoff that manages to percolate to the water table, point pollution from other sources that becomes permanently part of the water table (or “permanent” in human terms, anyway, potentially lasting for thousands of years), and are generally not monitored except when the property changes ownership, which can mean decades between formal, calibrated tests. Municipal water systems, on the other hand, are constantly monitored. And while negligence can happen, as in the case of the Flint, Michigan public water supply, those are exceptions. As much as there is for me to dislike about aspects of Connecticut, the MDC sends periodic reports that one doesn’t have to be a chemist to read and understand. I’m relatively happy with the MDC.
