Flint, Michigan, is nearly finished replacing lead pipes 11 years after the water crisis. Financial struggles still cloud the water system's future.

There’s tons of documentation on the plume’s legal, technical and local history, but finding answers to big-picture questions can be difficult. Here's what I've learned after 18 months of research.

The Great Lakes Water Quality Agreement needs to be updated to address the urgent issue of microplastic pollution. Scientists suspect high levels of microplastics in the Great Lakes because they are landlocked, and closer to people, which are the main source of plastic pollution.

Locals have been pushing for more aggressive solutions to the Gelman plume, but the company isn't required to fully clean it up. EPA intervention could change that — if it survives Trump 2.0.

Since the 1990s, cyanobacterial blooms have become increasingly common each summer in western Lake Erie. The blooms are cause by an overabundance of nutrients, namely phosphorus, that spills into the lake off farms.

The Great Lakes temperatures are slightly cooler than typical for this time of year. Overall climate change is causing the lake temperatures to increase.

Rita Loch-Caruso and the Yale Superfund Research Center want to use Ann Arbor’s case study to learn more about what they call “another forever chemical.” There’s a lot to learn and a surprising amount that isn’t known.

Marianne Martin has lived in the same home for over 50 years, despite groundwater contamination that rendered her drinking water well unusable. She sued the company responsible — and lost. Now she’s worried the same contamination could threaten Ann Arbor's drinking water.

Water-based economic researchers in the Great Lakes region are seeing U.S. government resistance to funding world-changing hub for water technology.

Decades of industrial pollution on Lake Superior has seen stretches of its shore deemed areas of environmental concern for both Canada and the U.S. A massive investment of time and money is letting nature return.
