![]() ![]() Environmental Protection Agency published a report about how high water age causes undesirable changes in the chemical, microbiological and physical quality of drinking water. As engineers, scientists and public health professionals, we are studying the health effects of drinking water and concerned that not enough attention is being paid to what high water age can mean for public health. The water age, or time water spends in pipes from treatment to consumption, increases. Consequently, shrinking cities can have drinking water sit in their old and corroded distribution system pipes longer than desired. Oversized water treatment and distribution systems are common in shrinking cities that experience less water demand than they did decades ago. Water systems are typically designed for growth, not shrinkage. So the infrastructure, which is largely underground, out of sight and out of mind, deteriorates largely outside of the public eye. ![]() Shrinking cities often don’t have the tax base to pay for maintenance and replacement needs. Many of the pipes and treatment plants built with those funds are now approaching or have exceeded the end of their expected lifespan. drinking water occurred after the World Wars and through the Drinking Water State Revolving Fund created by the 1996 amendments to the Safe Drinking Water Act. Major federal and state investments in U.S. Urban shrinkage can be bad for drinking water in two ways: through aging infrastructure and reduced water demand. Although shrinking cities exist across the U.S., they are concentrated in the American Rust Belt and Northeast. The geographic locations where Americans live are shifting in ways that can negatively affect the quality of their drinking water.Ĭities that experience long-term, persistent population decline are called shrinking cities.
