Access to clean and safe water does not come easily. While we may have mental images of people in distant parts of the world spending their whole day traveling to and from water sources and preparing it so that it is safe to consume, in the United States, we’ve come to expect clean and safe water at the turn of a tap. This water that flows freely from our faucet didn’t get there quickly, however. In order to provide safe and clean drinking water, systems collect water, treat it through various means, and disseminate it out through a complicated infrastructure system, so that it can show up in our household when we want it. Large urban water systems in the United States may have their own special challenges with consent orders and older infrastructure. But small water systems in the United States have special challenges owing to their size. There are probably more of these “small” water systems in this country than you realize.
