Chloride pollution of surface water and groundwater is an intractable problem. On one hand, sodium chloride (salt) is an important component of winter maintenance efforts that keep roads and other traveled surfaces free of snow and ice. On the other hand, many scientific studies have examined the potential risks to human health and natural resources associated with excess chloride in the environment, such as deteriorated ambient water quality, toxicity to aquatic and benthic organisms, adverse effects on vegetation, and even impacts to drinking water supplies. Yet little of that scientific wor ..read more

Chicago’s water policy has been a regular subject of conversation at the Law School, whether in the form of public events, faculty scholarship, or blog posts. So, too, has the history and development of the Great Lakes Compact. Today’s post digs into the unique relationship between the two, given the recent announcement that Chicago has entered into a water supply agreement with the city of Joliet, approximately 35 miles to the southwest. Chicago will supply treated Lake Michigan water to Joliet for a century, beginning in 2030, at a cost estimated to approach $1 billion in today’s dollars. T ..read more

In June 2022, Wisconsin lawmakers approved a new drinking water standard for two of the most widely used per- and polyfluoroalkyl substances (PFAS). Prized for their water and stain-resistant properties, PFAS are found in an array of industry and consumer products, including firefighting foam, cosmetics, waterproof fabrics, nonstick cookware, and food containers. These human-made compounds are commonly referred to as “forever chemicals.” Resistant to chemical breakdown, they persist and accumulate in our bodies and environment. A growing body of scientific evidence links these chemicals to inc ..read more

Flooding is the most common and most costly natural disaster in the United States, and the toll it takes is only expected to grow over the coming years. Rising sea levels, more powerful hurricanes, and more intense rainfall—all worsening thanks to climate change—will displace people from their homes and put increasing strain on the systems ..read more

When it rains or snows, the resulting runoff can collect pollutants including salts, fertilizers, chemicals, oils, and sediment, among other things. These contaminants have the potential to impair surface water and groundwater that receive the runoff. Communities in the United States face growing challenges to effective stormwater management as a result of aging infrastructure, increasing urbanization, changing ..read more

  As summer began, one of my colleagues introduced readers of this blog to Tom Merrill’s and my new book, Lakefront: Public Trust and Private Rights in Chicago (Cornell University Press 2021). The book explores how Chicago, a city known for commerce, came to have such a splendid public waterfront—its most treasured asset. Tom and ..read more

About four years ago I wrote a blog post titled “The Quiet Revolution in Wisconsin Administrative Law.” My purpose then was to point out an “unprecedented makeover in longstanding principles of state-level administrative law” that “shift[ed] power away from agencies and toward courts, the legislature, and the governor.” Last week the Wisconsin Supreme Court finally ..read more

Thank you to my colleague, Professor David A. Strifling, director of Marquette Law School’s Water Law and Policy Initiative, for his generous post a few weeks ago concerning Tom Merrill’s and my new book, Lakefront: Public Trust and Private Rights in Chicago (Cornell University Press). The book ranges over almost two centuries and the different ..read more
